Description

Fiber-opening apparatus

The application's denomination of invention that to be the applicant propose on November 11st, 2003 is dividing an application of 200310103660.4 application for a patent for invention for " fiber-opening apparatus that the compound spun yarn of length, its manufacture method, the greige goods fabric of using it and composite spinning are used ", application number.

Technical field

The present invention relates to drafted staple fibre bundle and opened fine synthetic fiber multifilament overlap, while by implementing really to twist with the fingers (actually twisting) fiber-opening apparatus that the compound spun yarn of novel length that obtains and manufacture method, the grey cloth that has used it or fabric and composite spinning use of reeling.

Background technology

In the past, as with staple fibre bundle and multifilament composite methods, known had: with the drafted staple fibre bundle looping multifilament of boundling state roughly, the method for twisting winding (1) perhaps by the false twisting looping, forms the method (2) of silk with coiling fine hair then; Or use the fine drafted fibre bundle of multifilament looping, the method for twisting winding (3) then opened; Perhaps, form the method (4) of silk with coiling fine hair by the false twisting looping.

, the shortcoming that exists in the said method (1) is, in order to strengthen the complexing of drafted fibre bundle and multifilament, must add the more twisting count of twisting count than the common spun yarn that only is made of staple fibre (staple).The shortcoming that exists in the said method (2) is in addition, and because of as if only carrying out the false twisting looping, complexing difference and can not become useful silk is so must take the method for deadlocked, fusion or loose twist.

The shortcoming that has said method (3) to exist again is though the silk of being reeled in the twisting back evenly, to have smooth sense and reflective.In the said method (4), too opened fibre because of multifilament and make staple fibre can not give full play to effect as coiling fine hair, therefore silk is in that the inconstant situation of looping state is more longitudinally.

In addition, the someone has proposed to make fibre bundle and the bulky yarn method (for example opening clear 49-101639 communique with reference to the spy) of winding mutually., owing to must once make fibre bundle be in excessive state, reach and use high speed rotating flow spinning head etc. in this method, exist easy generation bonding and shortcoming inhomogeneous, outward appearance (appearance) variation.

The somebody has proposed, in the compound silk that constitutes by long filament composition and staple fibre composition, the long filament composition is configured in core, the staple fibre composition is configured in the structure (for example open clear 59-30925 communique and the spy opens clear 61-239036 communique) of sheath portion with true sth. made by twisting shape with reference to the spy., the snowflake sense of this compound silk when catching different colours respectively is bad, and the specking that dark color adds man-hour is many, and the number of stoppages during weaving is many.

In synthetic fiber, the acrylate series fiber is gazed at as having the fiber of high function (temperature adjustment, damping, mediation), and in order to bring into play its feature, the spun yarn of acrylate series fiber and other materials blending is used to the system of knitting of a part of sweat shirt underwear.But the intensity of acrylic ester resin has only 0.55-1.82g/d, and knot strength is 0.30-1.5g/d, extremely a little less than, therefore exist the shortcoming that is subjected to further damage in the blending process with other materials and brings out staple fibre fracture and fibre shedding etc.This shortcoming becomes remarkable along with the rising of the rate of using with of acrylate based material.

On the other hand, if the rate of using with of acrylate based material is reduced, though above-mentioned shortcoming can be eased a little, the mortality problem as the characteristic remarkable reduction of functional fiber can take place.Therefore, there is very big problem in the blended yarn that contains the acrylate series fiber that in the past used aspect the quality of the rerum natura of silk and silk.Be, to make the rate of using with of acrylate series fiber be subjected to bigger restriction, and then for spinning number, also be only limited to low count yarn in detail because the damage the when rerum natura of acrylate series fiber and technological process can cause the remarkable decline of an intensity.

In addition, with regard to the quality of silk, the fracture that exists the staple fibre that takes place when the technological process because of the acrylate series fiber significantly increases the quantity of the filoplume that spun yarn has, and then this filoplume increases in the position that produces of vertically concentrating of silk, thereby makes the significantly reduced shortcoming of quality of silk.Like this, when the dyeing cloth and silk, the position that filoplume is concentrated seems to turn white and causes the also significantly reduced fatal shortcoming of the quality that makes cloth and silk.Therefore, the blending spun yarn that contains the acrylate series fiber generally is used in the inboard of cloth and silk, or is defined to the not too high purposes of requirement to the quality of cloth and silk.

Have, as the using method of the fibrous physical property of having considered the acrylate series fiber, what attempt morely is again, will pulverize the acrylate series fiber and forms short fibre object and add the method for man-hour with coatings such as coating in dyeing.From give functional aspect this be good method, but because of can make feel hardening, the thickening of cloth and silk with coating acrylate series fibers such as coating, have the problem of the original feel that has of damage cloth and silk, so aspect purposes, still can be restricted.

In recent years the needs for the high-quality sweat shirt underwear cloth and silk of having brought into play the high functionality that the acrylate series fiber had become strong.If as the above, improve the rate of using with of acrylate, be difficult to give the high functionality that this fiber has.

Therefore, at present, the compound silk that has used the acrylate series fiber as mentioned above is not also by known to the people.

On the other hand, as the method for making compound silk, establish method for fiber by cable and be known (as, the spy opens clear 54-17063 number).In addition, also being disclosed of compound silk of double-decker silk or fibre bundle and single thread etc. (for example, the spy opens flat 6-228838 number and the spy opens 2000-17532 number).In these communiques, there is not the relevant record of having used the compound silk of acrylate.

The compound spun yarn of length can make mixed filament by the combination of various fibers, perhaps can make various forms by various complex methods., the compound spun yarn of length that uses the solution dyeing silk for further improvement feel and form and aspect is not also by known to the people.If utilize the solution dyeing silk, the even undercompounding that takes place during then because of the manufacturing of solution dyeing silk, it is irregular to produce fiber number on the solution dyeing silk, or because of the solution dyeing particulate, produces the problem that reed or sewing needle are worn in manufacturing procedures such as weaving.

As the solution dyeing silk, known have mixed the solution dyeing silk of the particle of pigment etc. in synthetic fiber such as polyester, nylon, and relevantly how to open fine these silks hardly by known to the people.Particularly the black polyester fiber that obtains by solution dyeing (hereinafter referred to as black solution dyeing silk) normally when polyester reacts, or after polymerization to any stage that is shaped, by add that carbon black makes (as, open flat 8-13248 communique with reference to the spy)., use this solution dyeing silk to implement to open fibre and when making compound silk, be difficult to open equably fibre.(as, with reference to special fair 4-78749 communique and special public clear 54-17063 communique), the color spot of the compound silk that obtains is obvious, is difficult to use on the clothing of formal social usefulness such as full dress.When silk is not opened fibre equably, be made into behind the cloth and silk more significantly problem of its color spot with regard to existence.

Make as above-mentioned compound spun yarn the time, as making multifilament open fine device, known have an electric fiber-opening apparatus, for example, multifilament is passed through in the voltage additional electrodes of tubular, then in ground loop, pass through, make the silk ribbon electricity and make it out fine device (real public clear 50-9366 communique); And to behind the multifilament spraying compressed fluid, make it in the voltage additional electrodes by tubular, then in ground loop, pass through, make the silk ribbon electricity and make it out fine device (real public clear 50-35149 communique).

The influence of kind of opening tension force (tension) that fiber number is subjected to silk is applied, surrounding environment (as temperature, humidity), multifilament of multifilament etc. in such electric fiber-opening apparatus.If for example improve the transporting velocity of multifilament, the carried charge of multifilament descends, and the tension force of silk is increased, and opens the fiber number variation.Therefore,, be necessary experience and pilot study, determine size and the transporting velocity of silk and the size of tension force of applied voltage according to operating personnel in order to guarantee the stable fiber number of opening corresponding to the change of operating condition.

Therefore, in order to improve operating efficiency, requiring provides a kind of no matter how operating condition changes, and can guarantee the stable electric fiber-opening apparatus of opening fiber number of multifilament.

In this fiber-opening apparatus,, make the voltage additional electrodes inside of silk by tubular in order to make multifilament charged and make it out fibre.Therefore, if multifilament is opened fibre fully, then held the silk outlet that fine silk can be contacted with electrode continuously, this outlet just is subjected to loss easily so.Its result if multifilament is fully opened fibre, just need change the electrode of loss continually, and the operation that thereupon causes stops to cause operating efficiency decline to wait other problem.

Therefore in order to improve operating efficiency, require to provide to guarantee multifilament stable to open the fiber-opening apparatus that fiber number can prevent the loss of voltage additional electrodes again.

If observe the cross section of compound spun yarn of the present invention, it is characterized in that, form central core by the even mixed layer of synthetic fiber multifilament and staple fibre, and the staple fibre group surrounds this central core, to adjust form.

Compound spun yarn of the present invention has good complexing, the feel that wool matter is arranged, when making fabric and knitted fabric, can be made into lightweight and the little fabric of penetrating sense, minimizing obtaining high dark color and specking aspect the formal occasion purposes of black is applicable to man's western-style clothes and formal full dress, senior dress and overcoat.

Light-weight fabric of the present invention is that the compound spun yarn of above-mentioned length is used as warp thread or/and weft yarn, the average Density coefficient (Av.count factor) that is woven into longitude and latitude in the plain cloth reaches 35-47, is woven into the scope that the average Density coefficient of longitude and latitude reaches 45-60 in the TWILL CLOTH and obtains.

The said plain cloth of the present invention is the fabric that weaves based on the tissue with the plain of one of three foundation weave, but with the tissue that the elementary organization that changes this plain forms, the fabric that weaves as rib tissue, seven strand canvas tissues is also included within the plain cloth.

The said TWILL CLOTH of the present invention is the fabric that weaves based on the tissue with the drillipg of one of three foundation weave, but with the tissue that the elementary organization that changes this drillipg forms, the fabric that weaves as diagonal weave, rhombus twill-weave etc. is also included within the TWILL CLOTH.

The averag density coefficient of the longitude and latitude of light-weight fabric of the present invention is 35-47 in plain cloth, it is desirable to be made in the scope of 38-45, and in TWILL CLOTH 45-60, it is desirable to be made in the scope of 48-57.

Here, in plain cloth, if the averag density coefficient of longitude and latitude is lower than 35, the penetrating sense of fabric can become excessive, and can not guarantee the Practical Performance of fabric, and is not ideal.In addition,, just can not obtain desirable gas permeability if the averag density coefficient of longitude and latitude is higher than 47, also not ideal.In TWILL CLOTH, if being lower than 45, the averag density coefficient of longitude and latitude just can not guarantee the Practical Performance of fabric and not ideal, if the averag density coefficient of longitude and latitude is higher than 60, just can not obtain desirable gas permeability, also not ideal.

The bulkfactor T of warp thread is, with warp thread radical/(number) among the wide 10cm of fabric ^1/2, the bulkfactor W of weft yarn is with weft yarn radical/(number) among the wide 10cm of fabric ^1/2Calculate, the averag density coefficient of the longitude and latitude of light-weight fabric of the present invention calculates with (the bulkfactor W of the bulkfactor T+ weft yarn of warp thread)/2.

The air permeability of light-weight fabric of the present invention is 50cc/cm ²More than the sec, it is desirable to 90cc/cm ²More than the sec.If air permeability is lower than 50cc/cm here ²Sec is then descended by the ventilative ventilation heat release meeting that brings, and can not get refrigerant sense, thereby not ideal.

Air permeability can use Fu Leize (Frazier) type tester to measure.

Compound spun yarn with above-mentioned special cross-section form of the present invention, by with the electric fibre of opening of synthetic fiber multifilament, overlap in the dead ahead of preliminary roller with drafted staple fibre group then and when making compound spun yarn, the staple fibre of center that can be by will opening the multifilament behind the fibre during with described the coincidence must silk the center coincide together and reach, feeding tension that particularly can be by control synthetic fiber multifilament or open fine voltage and make out fine amplitude variation narrow, perhaps make out fine amplitude variation narrow with special-purpose thread-carrier, the even mixed layer of synthetic fiber multifilament and staple fibre is concentrated on the center of compound spun yarn, and form around surrounding it by the staple fibre group.

In the manufacture method of compound spun yarn of the present invention, electric opening after the fine synthetic fiber multifilament, with trailed staple fibre group preliminary roller just before in main the coincidence, importantly the fine width of cloth of opening of synthetic fiber multifilament is set for staple fibre must clump amplitude peak identical or be lower than amplitude peak.

If the synthetic fiber multifilament open the biggest that fine amplitude ratio staple fibre must clump, just can not obtain the silk structure that staple fibre surrounds the even mixed layer of long filament and staple fibre, the fine hair lodging effect that is produced by long filament increases, and then can not get lightweight and the little fabric of penetrating sense, and is not ideal.

Therefore be necessary to set for the fine width of cloth of opening of synthetic fiber multifilament with staple fibre must clump the most identical or be lower than that staple fibre must clump the most significantly, it is desirable to be set at the most significantly 10-60% that staple fibre must clump.In the cross section of the compound spun yarn of producing thus, even mixed layer by multifilament and staple fibre has formed central core, and staple fibre surrounds this central core, is expected to obtain special silk structure and effect (the little fabric of the raising of weaving, lightweight and penetrating sense, high bathochromic effect and the minimizing of specking).If here multifilament open that the fine width of cloth is lower than that staple fibre must clump the most significantly 10%, can descend by holding fine effect, weaving can drop to the level of core silk, can not get the effect of above-mentioned purpose, and is not ideal.

Synthetic fiber multifilament and staple fibre must clump the special-purpose thread-carrier that can utilize out the position of fine electrode or open fine long filament of determining of supply position adjust.The adjustment of opening the fine width of cloth of synthetic fiber multifilament depends on out the special-purpose thread-carrier of fine voltage, feeding tension, long filament etc.

The compound spun yarn of length of the present invention can use device as shown in Figure 2 to make.Promptly according to Fig. 2, dispose back roller 1, reel cage 2, preliminary roller 3 in this device successively, preliminary roller 3, and below preliminary roller 3, dispose twizzle 4, and the below disposes the coiler device that possesses steel loop and steel traveler (traveler) 5 again, and the top of sending into side of described preliminary roller 3 has static from top to bottom and adds fine electrode 6 of opening of usefulness and ring-type thread-carrier 7.

The manufacturing of the compound spun yarn of length is, at first unties the multifilament A on the cop 8, adds static through thread-carrier 9 usefulness electrodes 6 and makes it out fibre, on one side then open the fine width of cloth by 7 controls of ring-type thread-carrier on one side and preliminary roller 3 is supplied with in the supply position.On the other hand, rove B is supplied with back roller 1, drawing-off between reel cage 2 and preliminary roller 3 then makes fiber and must supply with preliminary roller 3 behind the staple fibre bundle B of clump (fleece) shape.The staple fibre bundle B that multifilament A and fiber behind the fibre must the clump shape that opens that is supplied to preliminary roller 3 mixes in the faller gill setting point of preliminary roller 3, at this moment controls the fine width of cloth of opening of multifilament and be the most significantly 10-60% that staple fibre must clump, and coincides with center that staple fibre must clump width of cloth and mix.The multifilament and the staple fibre that have passed through preliminary roller 3 must be formed the special silk structure that cross section middle short fiber group surrounds the even mixed layer of long filament and staple fibre by twisting by clump, and through being wrapped on the pipe silk 10 by steel loop and steel traveler 5 behind the twizzle 4.

The compound spun yarn of the 3rd main points of the present invention, the filoplume above with 1mm calculates, be advisable with hairiness index with 200-900/10m, so on this basis the above filoplume of 5mm 30/be better below the 10m.This is for the feel of bringing into play wool matter improves back processabilities such as weaving again, so when suppressing weaving cotton knot generation and improve the quality of commodity.Here said hairiness index is to measure with the F-イ Application デ Star Network ス テ ス one that applies island weaving Co., Ltd. system.

The compound spun yarn of the 3rd main points of the present invention is characterised in that if observe its cross section, multifilament group and staple fibre group are arranged in swirl shape.Can about the direction of vortex.This can be by reaching in the coincidence position of spinning stage control long fiber bundle and staple fibre bundle.

The compound spun yarn of the 3rd main points of the present invention has good complexing, the feel that wool matter is arranged, after making fabric and knitted fabric, it is few and be imbued with the cloth and silk of gas permeability that the formal occasion that the snowflake sense in the time of can obtaining that long filament and staple fibre dyed different colours respectively increases, implements black adds the specking minimizing in man-hour or filoplume with the dark color of clothing.Therefore be applicable to man's western-style clothes and formal full dress, senior dress and overcoat.

This compound spun yarn identical fabric in the time of can being woven into compound spun yarn with above-mentioned the 1st main points, the above-mentioned explanation of the relevant fabric that is made into from the compound spun yarn of the 1st main points all is suitable for the fabric of the compound spun yarn of the 3rd main points.

With the electric fibre of opening of synthetic fiber multifilament, overlap with drafted staple fibre group in the dead ahead of preliminary roller then and when making compound spun yarn, if the pass of the maximum open-width H of the staple fibre palpus clump during described coincidence the and the maximum open-width h of long fiber multifilament is, distance from the end points of H to the end points of h overlaps with respect to the 10-90% that the most significantly staggers of H, just can reach above-mentioned, according to the manufacture method of the compound spun yarn of the special section morphology of having of the 3rd main points of the present invention.

The important point is in the manufacture method of above-mentioned compound spun yarn, with the electric fibre of opening of synthetic fiber multifilament, then with drafted staple fibre group when the dead ahead of preliminary roller overlaps, supply shaft that must clump synthetic fiber multifilament and staple fibre staggers.

The maximum open-width h of synthetic fiber multifilament preferably set must clump with staple fibre maximum open-width H identical or greater than it.If less than staple fibre must clump the width of cloth, the fine hair that is brought by long filament lodging effect descends, weaving reduction and then the quality of cloth and silk is reduced is not ideal.

In addition, be necessary to make the 90-10% of the maximum open-width that staple fibre must clump, preferably the maximum open-width h of the length of 80-20% and multifilament is overlapping.In the cross section of the compound spun yarn of producing thus, be formed with long and short two kind material respectively as the vortex of the volume sushi shape of laver, sushi meal special silk structure and the effect (increase, the dark color of the minimizing of filoplume, the raising of weaving, the snowflake sense when dying different colours respectively add the minimizing of specking in man-hour) that are expected to obtain.Here, if the stack of the open-width of the open-width of multifilament and staple fibre palpus clump disappears, perhaps both separate fully, and compound structure will change and can not form gyrate silk structure so, can not get the silk effect as above-mentioned purpose, and will be not ideal.

Synthetic fiber multifilament and staple fibre must clump the decision meeting of supply position the structural configuration of the silk produced is exerted an influence.During silk that spinning Z twists with the fingers, the synthetic fiber multifilament must be staggered by clump to the right facing to staple fibre, during silk that spinning S twists with the fingers, stagger to the left side that staple fibre must clump.Can obtain more stable target silk structure thus.At this moment, the vortex direction in the cross section of silk is as follows, is clockwise direction when promptly Z twists with the fingers, and S is counterclockwise when twisting with the fingers.

Decision synthetic fiber multifilament and staple fibre must clump the supply position time, can adjust with position of opening fine electrode or the special-purpose thread-carrier of opening fine long filament.The adjustment of opening the fine width of cloth of synthetic fiber multifilament is to finish by the special-purpose thread-carrier of opening fine voltage, feeding tension, long filament etc.

The compound spun yarn of the length of the 3rd main points of the present invention can be made by the control spinning conditions with the device shown in Figure 2 that has illustrated.

When making the compound spun yarn of length, at first untie the multifilament A on the cop (pirn) 8, add static through thread-carrier 9 usefulness electrodes 6 and makes it out fibre, on one side then open the fine width of cloth by 7 controls of ring-type thread-carrier on one side and preliminary roller 3 is supplied with in the supply position.On the other hand, rove B is supplied with back roller 1, drawing-off between reel cage 2 and preliminary roller 3, the staple fibre bundle B that makes fiber palpus clump shape supplies with preliminary roller 3.The staple fibre bundle B that multifilament A and fiber behind the fibre must the clump shape that opens that supplies with preliminary roller 3 mixes in the faller gill setting point of preliminary roller 3, the length of 10-90% of the maximum open-width of staple fibre palpus clump is coincided with the maximum open-width of multifilament and mixes.Multifilament and staple fibre by preliminary roller 3 must silk be gyrate special silk structure by formed cross section by twisting, are wrapped on the pipe silk 10 by steel loop and steel traveler 5 through twizzle 4 backs.

Describe the compound silk of the 5th main points of the present invention below in detail.

This compound silk is the compound spun yarn of length that contains the acrylate series fiber.The acrylate series fiber that uses among the present invention is the fiber that is made of acrylic acid and light metal salt thereof, acrylamide crosslinking copolymer, is the fiber with good temperature adjustment, damping, mediation character.Fibre strength and knot strength are extremely low in the rerum natura of acrylate fiber, are to be usually used in about the 1/2-1/3 of the synthetic fiber of dress material such as polyester fiber.

Therefore, acrylate series fiber and natural fabric be or/and using with of synthetic fiber becomes indispensable, and be necessary and be compounded to form by the long filament that synthetic fiber constitute if will obtain high-quality strand.Make the maintenance of intensity become possibility by being compounded to form with the long filament that constitutes by synthetic fiber, it for fine-count yarn spin and the raising of the rate of using with of acrylate series fiber is effective.

Have, the desirable complex morphological that is used to obtain high-quality strand is again, use the long filament that constitutes by synthetic fiber with acrylate series fiber and natural fabric or/and the fibre bundle of synthetic fiber surround and be compounded to form.The long filament that is made of synthetic fiber is not particularly limited so if be used in the material of dress material, but considers that from the intensity aspect polyester and nylon are more satisfactory, has from silk quality aspect to consider that long filament number (count) is preferably more than 5 again.In addition, the rate of using with of shared long filament is preferably 10-35% in the compound silk.If be lower than 10%, then the rerum natura aspect and the silk quality raising effect deficiency.If surpass 35%, the quality that then contains the fibre bundle of acrylate series fiber can significantly descend, and the rate of using with of acrylate series fiber and spin number and can be subjected to big restriction is therefore not ideal as a result.

Be necessary the rate of using with of acrylate series fiber is set in 5-45%.Consider 10-40% more preferably from functional result and silk quality.If the rate of using with of acrylate series fiber below 10%, then is difficult to give full play to temperature adjustment, damping as the feature of acrylate series fiber, be in harmonious proportion these three effects, and is not ideal.In addition, if, then when the strand quality significantly descends, consider also not ideal from the cost aspect if the rate of using with surpasses 40%.

Also have, be necessary the concentrated filoplume that compound silk is had produce number 200/below the 1000m, it is desirable to 100/below the 1000m.

In addition, if will obtain high-quality cloth and silk, concentrate filoplume produce number 100/be advisable below the 1000m, it is desirable to especially 70/below the 1000m.Because the acrylate series fiber has non-staining shortcoming, if therefore should concentrate filoplume to produce manyly, the position that filoplume is concentrated on the cloth and silk after the dyeing seems and can turn white, thereby the quality of cloth and silk is significantly descended.Also have, can find that from various result of the tests concentrating the part of filoplume is the acrylate series fiber.

Because of producing, the acrylate series fiber concentrate the mechanism of filoplume to be speculated as, in the technological process because of to metal and to the friction of fiber the fracture of staple fibre takes place in a large number, it is bad to bring out drawing-off thus in each technological process, thereby causes the increase of a fault and the generation of concentrating filoplume.Owing to should concentrate filoplume to form the ball top bar, therefore should concentrate filoplume can be easy to statistics at same position.Computational methods are that upward according to 4 coiling things of 20/in pitch making, the concentrated filoplume that number goes out on each raw silk blackboard produces number, is converted into 1000m then and just can obtains a result at raw silk blackboard (fabric roll bending).In addition, can think that it is because of containing the phenomenon that the acrylate series fiber occurs that this concentrated filoplume is led to a phenomenon.This phenomenon becomes along with the increasing of containing ratio of acrylate series fiber significantly, and is rare in the material that does not contain the acrylate series fiber.

Also have, concentrate filoplume to produce number and can obtain by being compounded to form with long filament at 100/high-quality strand below the 1000m.Unqualified about complex morphological, be considered to especially effectively be described as follows.

For supply with by the rove supply unit by acrylate series fiber and natural fabric or/and the fibre bundle that synthetic fiber constitute, the long filament that to supply with by the long filament supply unit the fine device of electricity consumption air to open open under the fine state with overlaps after, implement true the sth. made by twisting and just can obtain high-quality strand (100 of concentrated filoplume generation numbers/1000m).

This is to obtain by really twisting with the fingers under the state of the concentrated filoplume that fine long filament group encirclement is caused by the acrylate series fiber.

As to by acrylate series fiber and natural fabric or/and the staple fibre bundle (B) that synthetic fiber constitute and make the method for compound silk by long fiber bundle (A) twisting that synthetic fiber filament constitutes, except that said method, also useful drafted fibre bundle encases twisting winding behind the multifilament of boundling state roughly or forms the method for silk by the false twisting looping with coiling fine hair; Or use the method that fine multifilament encases twisting winding behind the drafted fibre bundle or forms thread with coiling fine hair by the false twisting looping of being opened.Compound silk of the present invention can be made with any method wherein.

Have again, for supply with by the rove supply unit by acrylate series fiber and natural fabric or/and the fibre bundle that synthetic fiber constitute, under the state of giving tension force with tension mechanism, will form fibre bundle by the long filament coincidence of long filament supply unit supply by supplying with thread-carrier, and this fibre bundle and do not contain the acrylate series fiber by natural fabric or/and after the fibre bundle that synthetic fiber constitute merges with the interval of 3-8mm, add that true sth. made by twisting just can obtain high-quality strand.

This is by giving true sth. made by twisting two kinds of fibre bundles to be reeled mutually, in the orientation confusion that suppresses fiber and when suppressing the generation of filoplume, surrounds with the fibre bundle that does not contain the acrylate series fiber, makes two kinds of effect acting in conjunction results.

In addition, for supply with by the rove supply unit by acrylate series fiber and natural fabric or/and the fibre bundle that synthetic fiber constitute, under the state of giving tension force with tension mechanism, will form fibre bundle by the long filament coincidence of long filament supply unit supply by supplying with thread-carrier, and thereon by cord roller, under the state of not giving tension force from the outside of preliminary roller, winding filaments Yi Bian add true sth. made by twisting, also can obtain high-quality strand on one side.This is to use fibre bundle that the long filament of supplying with from the outside of preliminary roller will contain the acrylate series fiber almost to cover and the effect that produces.

Compound spun yarn to the 7th main points of the present invention is elaborated below.

Synthetic fiber (A) in the compound spun yarn of the present invention's the 7th main points can be common synthetic fiber, comprise as, the long filament that is made of polyester such as polyethylene terephthalate, polytrimethylene-terephthalate, polytetramethylene terephthalates; Perhaps by polyamide such as fatty polyamide, aromatic polyamides, the long filament that forms of nylon 6, nylon 66 for example; The perhaps long filament that forms by polyolefin such as polyethylene, polypropylene; Long filament that forms by synthetic resin by long filament of propenyl or acrylic ester etc. etc.Consider particularly polyethylene terephthalate of preferred polyester series fiber from processing and cost aspect.

As polyester fiber, except common polyester, copolyester can list particularly: M-phthalic acid, adipic acid, decanedioic acid, naphthalene dicarboxylic acids, phthalic acid, propylene glycol, butanediol, diglycol ethylene etc.

The fiber number of synthetic fiber is to be advisable below the 300dtex.If surpass 300dtex, if do not set high voltage, opening fibre will variation, because production cost increases and the fiber number of making compound silk when holding fine compound spun yarn can become excessive, therefore not ideal.Comparatively ideal scope is 10-150dtex, and 15-100dtex is better.

About supplying with the finish of the synthetic fiber (A) among the present invention, the important point is, by being selected from a kind of in alkylsulfonate, alkylbenzenesulfonate, alkyl sulfate, the alkylphosphonic or their composition is formed antistatic additive.

Antistatic additive is in order to make the electric well composition of opening fibre and must having of fiber, its content with respect to the finish composition preferably more than the 12 weight %, below the 50 weight %.If be lower than 12 weight %, then synthetic fiber open the fibre variation, and will use the quality variation of the compound spun yarn of synthetic fiber of the present invention, be considered as not belonging to scope of the present invention.If surpass 50 weight %, being fuming in the stretching engineering becomes remarkable and not ideal so.Desirable scope is 15-40 weight %, and 18-30 weight % is better.

The adhesion amount of finish is with respect to the synthetic fiber weight that contains particulate, preferably below 1.1%.If surpass 1.1 weight %, though antistatic property can improve, problem such as oil dripping takes place and not ideal.Single thread fiber number with respect to synthetic fiber, there is suitable finish adhesion amount, when for example the single thread fiber number is thick because fiber surface area diminishes relatively, so adhesion amount is less for well, when opposite single thread fiber number is thin because fiber surface area becomes greatly adhesion amount set for and mostly be.In the present invention, find that if be set at 0.2-1.1%, the fibre of opening of fiber just becomes good when the single thread fiber number is 1-2.5dtex.Preferred especially 0.3-0.9%, 0.4-0.7% is better.

By giving above-mentioned finish, can open fibre with the aftermentioned method.As the parameter of opening fibre of energy rational evaluation synthetic fiber, if the resistance value under the preferred 25 ℃ * 40%RH is 8 * 10 ⁸Below the Ω, also show the good fibre of opening even contain the synthetic fiber of carbon black so.If surpass 8 * 10 ⁸Ω opens fibre and becomes inhomogeneous, forms with staple fibre and is easy to generate color spot when opening fine compound spun yarn.If but be lower than 1 * 10 ⁴Ω just is necessary to adhere in large quantities antistatic additive, and this can make on the contrary holds the fibre variation, therefore it is desirable to 1 * 10 ⁵Ω is above, 6 * 10 ⁸Below the Ω, more preferably 1 * 10 ⁶Ω is above, 4 * 10 ⁸Below the Ω.

Antistatic additive of the present invention is preferably by being selected from a kind of in polyoxyethylene alkyl amine, polyethylene glycol oxide alkylamide, polyoxyethylene alkyl ether, polyxyethylated phenylate, fatty acid glyceride, sorbitan fatty acid ester, alkylsulfonate, alkylbenzenesulfonate, alkyl sulfate, alkylphosphonic, ammonium chloride, ammonium sulfate, ammonium nitrate, alkyl betaine-type, alkyl imidazoline type, the alkyl alanine or their composition is formed.Antistatic additive in addition can not satisfy out fibre.Alkylsulfonate, alkylbenzenesulfonate, alkyl sulfate, the alkylphosphonic of wherein special preferred anionic system, wherein more preferably metal organic sulfonate.

As attached to the finish on the synthetic fiber that contain particulate of the present invention, with oil component 40-70 part, emulsified component 5-30 part, the scope of antistatic additive 12-50 part constitutes suitable.If oil component is lower than 40 parts, becomes too high with the coefficient of friction that connects a part of metal or pottery etc. so and become the generation reason of filoplume easily.If emulsified component is lower than 5 parts, be difficult to mix during the dilute with water oil content so, not only form the attachment plaque of oil easily, and then also become the reason of filoplume and silk fracture easily.Ideal range is that oil component is 50-60 part, and emulsified component is 10-20 part, and antistatic additive is the scope of 18-30 part.

Among the present invention, can suitably be used in combination as known materials such as mineral oil and fatty acid esters as the basic ingredient of spun yarn finish.In addition, can at random be used in combination as known materials such as fatty acid glyceride, sucrose fatty ester, sorbitan fatty acid ester, methyl glycol fatty acid ester, POE ether addition oil, PEG ester addition product oil, lecithin as emulsified component, PEG dioleate, fatty acid alcohol and slaine thereof are for desirable especially.

Fiber of the present invention is advisable to contain particulate.Because of containing particulate the smooth degree of fiber surface is changed, by using above-mentioned finish can make the coefficient of friction optimization and improving and open fibre.

As being used in particulate of the present invention, particulate such as mixing pigment, delustering agent, antiseptic, antistatic additive in fiber of general energy all can.Particulate is by carbon black coloring the time, because of good the opening fibre and can reduce and mix fine spot of the present invention, can hang down the spot of losing lustre, and is Ideal Match therefore.In addition, in the scope of not damaging the object of the invention, can also contain other additive such as delustering agent, antiseptic, antistatic additive, and can contain other polymer.In addition, except the carbon black that black solution dyeing is used, can also use versicolor pigment as pigment.

As the adding method of particulate, the colour masterbatch synthetic resin that the carbon black by 5-40 weight % can be constituted and produce black solution dyeing polyester fiber for example by matrix polymer mixed melting and spinning that the synthetic resin of carbon black not constitutes.The content of carbon black is that benchmark is respectively 0.5-2.0 weight % with the fibre weight in this fiber.If be lower than 0.5 weight %, color spot is obvious, and just generation is bad with mixing of polymer if surpass 2.0 weight %, and it is obvious that the fiber number spot becomes.

In addition, when melting mixing colour masterbatch synthetic resin and matrix polymer, there is no need to adopt special method.For example, fusion again after the fragment separately before the fusion can being mixed also can be carried out static mixing with static(al) blender etc. after the fusion respectively with both before spinning.Mix the back and carry out fibration by known melt spinning method.The cross sectional shape of this moment can be arbitrarily, can be in circular cross-section fiber, profiled fibre, the doughnut any.

Employed carbon black is any carbon blacks such as channel carbon black, furnace black among the present invention, if but its initial size is too little, then for example be engaged in the PET series copolyester (below, sometimes only be called copolyester) in the time, the easy aggegation of particle and make throwing become the difficulty, if excessive on the other hand, degree of blackness reduces easily.Therefore the initial size of carbon black is advisable in the scope of 10-40nm.If particle diameter below 10hm, is then handled the difficulty that becomes, and if particle diameter more than 40nm, then the back pressure in the nozzle can rise during spinning, becomes the bad reasons of operability such as silk fracture.

In addition, by the rove supply unit supply with by natural fabric or/and the fibre bundle that synthetic fiber constitute (B) preferably use more than in wool, cotton, silk, fiber crops, synthetic fiber staple fibre, staple fiber and the acetic acid esters staple fibre any one.Preferred especially wool.

The above hairiness index of the 1mm that compound spun yarn had that obtains 1000/be necessary below the 10m.And if woods obtain high-quality cloth and silk, hairiness index 700/be better below the 10m.If the filoplume that produces is many, the place that filoplume is concentrated on the cloth and silk after the dyeing can seem to turn white so, thereby the quality of cloth and silk is significantly descended.

As to by synthetic fiber (A) and by natural fabric or/and the method for the compound spun yarn of the fibre bundle of the long filament that the fibre bundle that synthetic fiber are formed (B) constitutes twisting formation have, to roughly with drafted fibre bundle, the multifilament of boundling state encases, then by twisting winding or false twisting looping, form the method for silk with coiling fine hair, or use the multifilament of being opened fibre to encase drafted fibre bundle, twisting winding perhaps by the false twisting looping, forms the method for silk with coiling fine hair then.

Have again, for supply with by the rove supply unit by natural fabric or/and the fibre bundle that synthetic fiber constitute (B), the synthetic fiber (A) that to supply with by the long filament supply unit under the state of giving tension force with tension mechanism by supply with thread-carrier overlap and form, by natural fabric or/and the fibre bundle that synthetic fiber constitute (C), after the interval merging with 3-8mm, add that true sth. made by twisting just can obtain high-quality strand.

In addition, for supply with by the rove supply unit by natural fabric or/and the fibre bundle that synthetic fiber constitute (B), the synthetic fiber (A) that to be supplied with by long fiber (below be also referred to as long filament) supply unit overlap and form fibre bundle by supplying with thread-carrier under the state of giving tension force with tension mechanism, and thereon by cord roller, from the outside of preliminary roller under the state of not giving tension force, the synthetic fiber of reeling on one side Yi Bian add true sth. made by twisting, also can obtain high-quality strand.This is to use the synthetic fiber of supplying with from the outside of preliminary roller that fibre bundle (B) is nearly all covered and the effect that produces.

Except that said method, make synthetic fiber (A) charged in addition, Yi Bian Yi Bian open the fine method of making compound spun yarn then continuously.Charged and open fine suitable method continuously as making synthetic fiber (A), electrode just like the frusto-conical of record in the public clear 47-11248 of spy number, be limited to this but have more than, can also adopt the method for utilizing corona discharge as required, Ionized air as the method for medium, the method that contacts with high-field electrode etc.Among the present invention, for supply with by the rove supply unit by natural fabric or/and the fibre bundle that synthetic fiber constitute (B), the long filament that to supply with by the long filament supply unit the fine device of electricity consumption air to open open overlap under the fine state after, add that true sth. made by twisting just can obtain high-quality strand (700 of hairiness indexs more than the 1mm/10m).

When decision has the supply position of the long fiber synthetic fiber (A) of easily opening fibre and staple fibre bundle (B), can adjust by position of opening fine electrode or the special-purpose thread-carrier of opening fine long filament.The adjustment of opening the fine width of cloth of synthetic fiber multifilament can be by opening fine voltage, feeding tension, long filament the adjustment of special-purpose thread-carrier etc. finish.

The compound spun yarn of length of the present invention can use the device manufacturing shown in the Fig. 2 that has illustrated.

When making the compound spun yarn of length, at first untie the multifilament A on the cop 8, add static through thread-carrier 9 usefulness electrodes 6 and makes it out fibre, while then control out the fine width of cloth and preliminary roller 3 is supplied with in the supply position by ring-type thread-carrier 7.On the other hand, rove B is supplied with back roller 1, drawing-off between reel cage 2 and preliminary roller 3 then makes fiber and must supply with preliminary roller 3 behind the staple fibre bundle B of clump shape.The staple fibre bundle B that multifilament A and fiber behind the fibre must the clump shape that opens that supplies with preliminary roller 3 mixes in the faller gill setting point of preliminary roller 3, at this moment controls the fine width of cloth of opening of multifilament and be the most significantly 50-300% that staple fibre must clump, and with staple fibre must clump width of cloth the center coincidence and mix.The multifilament and the staple fibre that have passed through preliminary roller 3 must be formed the silk structure that the cross section is the even mixed layer of long filament and staple fibre by twisting by clump, through being wrapped on the pipe silk 10 with steel loop and steel traveler 5 behind the twizzle 4.

By the above compound spun yarn that obtains is that fibre bundle (B) mixes equably with the synthetic fiber with fibre (A) and executes to twist with the fingers and obtains.Therefore the generation of filoplume is also few, and in addition, when synthetic fiber (A) were the solution dyeing silk, heterochromatic snowflake sense became even.Have because filoplume is few, weaving also can be improved again.Can be used in common fabric, for example plain, drillipg, satin etc. also have common braided fabric, for example through volume, weft knitting etc.These braided fabrics of gained have good dark color, also do not have specking, and feel also is improved, and are specially adapted to the full dress that formal occasion is used.

In the synthetic fiber of the 8th main points of the present invention, contain the adhesion amount of the oil content of the antistatic additive that 12 weight % are above, 50 weight % are following, below 0.8%, the resistance value under 25 ℃ * 40%RH is 8 * 10 with respect to fibre weight ⁸Below the Ω.

Here said synthetic fiber are common synthetic fiber, and material cited in the synthetic fiber of its example and the long fiber bundle (A) of the compound spun yarn of formation of the 7th main points of the present invention is identical.

Have, said finish and resistance value are identical when containing the finish of antistatic additive and adhesion amount thereof and resistance value also with the compound spun yarn of explanation the 7th main points of the present invention again.

The synthetic fiber of the 8th main points of the present invention are advisable to contain particulate.By containing particulate, the smooth degree of fiber surface is improved, open the fibre raising, can preferably adopt.

These synthetic fiber are by black pigment painted the time, owing to of the present inventionly good open fibre and can reduce color spot, are Ideal Match therefore.In addition, in the scope of not damaging the object of the invention, also other additives such as delustering agent, antiseptic, antistatic additive can be contained, but also other polymer can be contained.In addition as pigment except that the carbon black that black solution dyeing is used, can also use versicolor pigment.

It is desirable to, the colour masterbatch synthetic resin that will be made of 5-40 weight % carbon black and by matrix polymer mixed melting and spinning that the synthetic resin of carbon black not constitutes is made black solution dyeing polyester fiber.The content of carbon black is benchmark with the fibre weight in this fiber, is respectively 0.5-2.0 weight %.If be lower than 0.5 weight %, hold fibre and can descend on the contrary, will produce badly if surpass 2.0 weight % with mixing of polymer, color spot is obvious on the contrary.

Same as described above, there is no need to adopt special method for melting mixing colour masterbatch synthetic resin and matrix polymer.For example, fusion again after the fragment separately before the fusion can being mixed also can mix both before spinning after the fusion respectively with static(al) blender etc.Mix the available known melt spinning method march fibration in back.The cross sectional shape of this moment is arbitrarily, can be in circular cross-section fiber, profiled fibre, the doughnut any.

The carbon black that uses is a carbon black arbitrarily, its kind and particle diameter with illustrated identical.

Said content was identical when in addition, the fiber number of synthetic fiber also was used for the synthetic fiber of compound spun yarn of the 7th main points with explanation.

Followingly electric fiber-opening apparatus of the present invention is illustrated with reference to accompanying drawing.

(the 1st example of fiber-opening apparatus)

Fig. 3 is the schematic cross-section of the 1st example of expression electric fiber-opening apparatus of the present invention.Fiber-opening apparatus 1 is set on the throughput direction of silk, possesses to have to have body 2 certain-length, that be made of insulator in the direction.Fiber-opening apparatus 1 also has the electrode 3 of the tubular of the substantial middle portion that connects body 2.This electrode 3 is connected on the power supply 4, from these power supply 4 applied voltages.In order to make multifilament charged and allow it in voltage additional electrodes 3, pass through.Fiber-opening apparatus 1 also has the nappe 5 that is made of insulator that throughput direction with respect to silk is positioned at the rear of voltage additional electrodes 3.Nappe 5 has yarn guiding port.Fiber-opening apparatus 1 also has the ground loop 6 of hollow, and this ground loop 6 is positioned at the place ahead of voltage additional electrodes 3 with respect to the throughput direction of silk, and the central shaft of electrode slightly becomes parallel with the central shaft of ground loop.The rear end 6A's of ground loop is interior big through the external diameter than the silk outlet 3B of electrode.The inner space of this ground loop 6 preferably has the shape of the interior warp of front end 6B greater than the frustum of a cone (using and rectangular two circular cones that parallel plane distinguishes of axes intersect) of the interior warp of rear end 6A.

Multifilament is stable opens fibre in order to make, and multifilament will be tried one's best and be carried from top to bottom in the fiber-opening apparatus 1, generally vertically is provided with, and promptly is arranged to nappe 5 on top, and ground loop 6 is in the position of bottom, but this is provided with direction and is not limited to vertical direction.

Voltage additional electrodes 3 can have the form of tubular by its inside for multifilament.Silk channel cross-section for the electrode vertical with the silk throughput direction 3 is not particularly limited, but passes through in order not influence multifilament, is advisable with circle in its cross section.

In order to ensure the stable fiber number of opening of multifilament, the length of voltage additional electrodes 3 is 15-70mm, it is desirable to 20-60mm, and that better is 25-50mm, and the interior of voltage additional electrodes 3 it is desirable to 0.5-3mm through being 0.3-6mm, and that better is 0.8-2mm.

In the fiber-opening apparatus 1,, make by its inner multifilament charged by this electrode 3 from 4 pairs of voltage additional electrodes 3 making alives of power supply.As long as therefore the material of voltage additional electrodes 3 can make multifilament charged, be not particularly limited.Example as the material of voltage additional electrodes 3 can list: metal, and as copper or silver etc., perhaps other conductive material, for example Markite, the mixing plastics that metal powder arranged or pottery etc.

Ground loop 6 is set on the throughput direction of silk the position more forward than voltage additional electrodes 3 in fiber-opening apparatus 1.And ground loop 6 joins with ground and is adjusted to roughly 0 current potential.Multifilament at first in the voltage additional electrodes 3 by and charged, then by being adjusted to the roughly ground loop 6 of 0 current potential, so can think that charged multifilament is to attracted to ground loop 6 and impel out fibre.Therefore the material of ground loop 6 is not particularly limited as long as can attract charged multifilament.Example as the material of ground loop 6 can list: metal, as iron, copper or silver etc., perhaps other conductive material is as Markite, the mixing plastics that metal powder arranged or pottery etc.

In order to promote the fibre of opening of multifilament more, with regard to the shape of the inner space of ground loop 6, on the throughput direction of silk, be positioned at dirty end (" front end ") and be advisable greatly than the end that is positioned at the upper reaches (" rear end ").For with silk throughput direction vertical direction on the cross section of ground loop 6 be not particularly limited.But in order to make multifilament open fibre equably with respect to its cross-wise direction, it is circular that the cross section of ground loop 6 is generally.

The stable fibre of opening for multifilament, the front end 6B's of ground loop is interior through being 6-25mm, it is desirable to 8-22mm, that better is 10-20mm, and rear end 6A's is interior through being 5-24mm, it is desirable to 6-20mm, that better is 7-15mm, the distance of front end 6B and rear end 6A is 3-25mm, it is desirable to 5-20mm, and that better is 7-15mm.

In order to ensure the stable fiber number of opening of multifilament, the silk outlet 3B of voltage additional electrodes is located to be had the position of 5mm apart from ground loop rear end 6A on the contrary direction of throughput direction of silk and is having between the position of 23mm apart from ground loop rear end 6A on the throughput direction of silk.It is desirable to, the silk outlet 3B of voltage additional electrodes is located to be had the position of 3mm apart from ground loop rear end 6A on the contrary direction of throughput direction of silk and is having between the position of 20mm apart from ground loop rear end 6A on the throughput direction of silk.Better is, silk outlet 3B is located at the position that 0-18mm is arranged apart from ground loop rear end 6A on the throughput direction of silk.But, condition is the silk inlet 3A of voltage additional electrodes is positioned at ground loop rear end 6A on the throughput direction of silk rear, and the silk outlet 3B of voltage additional electrodes is positioned at the rear of ground loop front end 6B on the throughput direction of silk.

In fiber-opening apparatus 1, use the body 2 that constitutes by insulator to cover around the voltage additional electrodes 3, be provided with at the rear of voltage additional electrodes 3 by the nappe 5 that is made of insulator with yarn guiding port with respect to the throughput direction by the silk in the voltage additional electrodes 3, operating personnel do not contact with electrode 3 to well as far as possible when the viewpoint of security is considered.In fiber-opening apparatus 1 of the present invention, body 2 and nappe 5 are not necessary inscape.

The voltage that is added on voltage additional electrodes 3 outward both can just also can be born.The absolute value that is added on the voltage of voltage additional electrodes 3 outward is 1-20kV, it is desirable to 1-10kV, and that better is 2-7kV.Multifilament transporting velocity in electrode is 0.03-0.70m/ second, it is desirable to 0.05-0.55m/ second, better is 0.07-0.45m/ second (rotating speed of the spindle of coiling multifilament is 3000-15000rpm, it is desirable to 4000-13000rpm, and that better is 5000-11000rpm).The tension force additional to multifilament is below the 10g weight, it is desirable to below the 5g weight, and better is below the 2g weight.

The long fiber that the multifilament that uses normally is made of above-mentioned synthetic fiber.

(the 2nd example of fiber-opening apparatus)

As the fiber-opening apparatus with the 1st example of the present invention, if multifilament is opened fibre fully, the silk outlet meeting of holding fine multifilament and voltage additional electrodes contacts continuously, and electrode becomes and is more prone to loss.Therefore in fiber-opening apparatus by in the front of wire electrode outlet equipment has through in the wire electrode outlet through an above stereoplasm tube that enters the mouth, directly do not contact to make multifilament as far as possible, thereby can prevent the loss of electrode with the voltage additional electrodes.

For fine multifilament is not contacted with the silk outlet of voltage additional electrodes, the existence of stereoplasm tube is preferably the place ahead of the silk outlet that is connected to the voltage additional electrodes at least mutually basically.

Stereoplasm tube has the interior form through identical tubular of its inlet and silk outlet usually.Can prevent and the contacting of wire electrode outlet if contact with the silk outlet of stereoplasm tube by multifilament, though so the silk inlet of stereoplasm tube and thread export interior through there being some differences also harmless.

Therefore the form that had of one of fiber-opening apparatus of this example is, an outlet of voltage additional electrodes is connected with an inlet of stereoplasm tube or is inserted into wherein, so that the silk that the silk of stereoplasm tube exports than voltage additional electrodes on the throughput direction of silk exports more on the front.Fig. 4 is that expression has the amplification sectional view around the silk outlet of the voltage additional electrodes 3 of fiber-opening apparatus of the voltage additional electrodes that is inserted in the stereoplasm tube and stereoplasm tube 7.The distance of silk outlet 7B that is connected with stereoplasm tube 7 or is inserted into the silk outlet 3B of voltage additional electrodes wherein and stereoplasm tube it is desirable to below the 7mm below 10mm, and better is below the 4mm.

With regard to the material of stereoplasm tube 7, when contacting, have sufficient rigidity and be advisable with multifilament.For example stereoplasm tube 7 is by hardness of matter such as pottery or stainless steels, and perhaps interior surface thereof constitutes with the material that hard particles such as diamond or carborundum cover.

Also guard electrode 3 can be inserted into the major part of voltage additional electrodes 3 in the stereoplasm tube 7 in addition.But at this moment must guarantee from the outside electrode 3 applied voltages.When being inserted in the major part of electrode 3 in the stereoplasm tube 7, for example, can not be inserted into stereoplasm tube 7 at the rear portion of silk throughput direction top electrode 3 and keep and expose state, thus electrode 3 is connected with power supply, perhaps the shortcoming part is set, is thus connected electrode 3 and power supply at the middle part of stereoplasm tube 7.

In order to reduce, the inner at least surface of the silk exit portion of voltage additional electrodes 3 to be formed by hardness of matter, and do not use above-mentioned stereoplasm tube 7 because of contacting the loss that produces with the multifilament of opening fibre.For example can be coated with the surface, inside of voltage additional electrodes 3 with hard particles such as diamond or carborundum.
