Description
Technical field
The present invention relates to a kind of production method that adopts zein fiber and the regenerative hemp fiber blended antibacterial composite yarn of making and disclose this composite yarn.
Background technology
Developing new Biodegradable fibers, be used for garment material or fabrics for industrial use, is one of important topic of current textile development research.Zein fiber is that (Polymer Company of CARGILL～DOW) and Japanese clock company such as spin and develop a kind of novel Recycled Fibers by Ka Jierdao.This fiber is to refine the acid fiber by polylactic of making by cornstarch, and promptly the PLA fiber is called zein fiber in China.
Zein fiber combines the advantage of natural fabric and chemical fibre.Its mechanical performance is between terylene and polyamide fibre, and intensity and modulus are lower than polyester fiber, are higher than polyamide fibre.Therefore, the zein fiber lining is soft, and gloss and brightness as the silk are arranged, and has good intensity, drapability, DIMENSIONAL STABILITY, elasticity and wrinkle resistance.Zein fiber has good biodegradable, buries in people's soil after 2～3 years, and intensity can disappear, and is decomposed into CO fully
2And H
2O.Its burning fuming amount is low, can not produce poisonous, harmful material.Zein fiber dyeability and terylene are basic identical, but hygroscopicity and resistance to elevated temperatures are poor, and its regain is 0.5%, and it is relatively poor that pure zein fiber fabric is worn moisture permeability, and the dyeing and finishing difficulty of processing is bigger.The spinnability of zein fiber is relatively poor, and similar terylene can purely spin, also can be natural fibre blended with cotton, wool or other.The zein fiber fabric can be used for fields such as clothes and mat filler, medical and sanitary products, articles for babies.
The zein fiber fabric has outward appearance retentivity and favorable biological degradability energy preferably.But zein fiber spinnability, hygroscopicity and resistance to elevated temperatures are relatively poor, and applying of this novel green fiber is restricted.And in the today of pursuing fashion, health care, it also is the big shortcoming of one that zein fiber does not have antimicrobial health care function.Though can or interweave with zein fiber and antibacterial dacron blending, can't improve its moisture permeability, and terylene is difficult to biodegradation, diminish the characteristic of zein fiber fabric environmental protection.
So, improve taking and the antibiotic health care performance of zein fiber machinability and fabric thereof, thereby the combination property and the added value that improve zein fiber become when last important topic.
Hemp also is to begin the tencel that develops in recent years.Its density is: 1.458g/cm
3Intensity is: 5.8～6.8g/dtex; Regain is 12%; Saturation regain is 50%.Hemp textile has a lot of premium properties.Hemp textile has the natural bacteriostatic function.Contain tetrahydrocannabinol (THC) and cannabinol etc. in the hemp, produce cannabinol through illumination and air oxidation meeting, effect such as this material has sterilization, cough-relieving, antispastic, pain relieving, sleep peacefully has Staphylococcus aureus, Escherichia coli, Candida albicans etc. and significantly to kill and inhibitory action.Because the lumen of hemp cell is bigger, it is more to be rich in amount of oxygen, and anaerobic bacteria can't be survived, thereby its anti-mildew bacteriostasis is more outstanding.The hemp textile sucting wet air permeability is good, and its regain is 12%, and saturation regain is 50%.Many crackles that the hemp center has an elongated cavity and fiber surface distributing link to each other with aperture, and excellent capillary effect makes hemp fabric moisture perspiration discharging performance especially good.Hemp textile has higher voidage, and it has good sound absorption properties and gas permeability, and good heat endurance is arranged, and can stand the test of 370 ℃ of high temperature.Therefore hemp textile also can be used for interior decoration except that being used for clothes.The room that hemp textile is decorated not only can reduce noise, and working to live to people provides a quiet space.Also because of its humidity absorption and release is good, the temperature and humidity in can conditioning chamber is a natural green air conditioner.Sun-resistant, the corrosion resistance and good of hemp.Therefore, the suitable especially Work Clothes of makeing sun-proof clothes and various special requirements of hemp textile also can be done parasol, Camp tent, fishing net, rope, automobile cushion, inner lining material etc.In addition, hemp cloth also has ultraviolet radiation preventing function.Detect through Physics Inst., Chinese Academy of Sciences: common clothing only can intercept 30%～90% ultraviolet ray, and general hemp cloth, need not special arrangement is the ultraviolet ray of maskable more than 95%.
Therefore, theoretically, hemp is the optimal raw material of underwear, summer clothes, bedding etc.But hemp has the common drawback of bast-fibre, and as yarn count is thick, lining is thick and heavy, ABRASION RESISTANCE, wrinkle resistance and conformality is poor, feel is coarse, contact skin has prodding and itching feeling.Above-mentioned shortcoming has limited the application of hemp on underwear, summer dress ornament greatly.Especially the hemp cast tow is even more serious, and filament length is short, be generally 20～50mm, and the length regularity of fiber is not high.Be unfavorable for so very much spinning, and difficulty spin in thin yarn (30tex following).Although can or interweave, can only improve its weaving processing to a certain extent and take performance, and diminish hemp cloth style and antibiotic health care performance with other fiber blends.
If zein fiber yarn and hemp line yarn line are interweaved, can improve the antibiotic and moisture permeability of zein fiber fabric, simultaneously, also can improve soft comfortableness, DIMENSIONAL STABILITY and the wrinkle resistance of hemp cloth, but final fabric lost the zein fiber fabric frivolous, soft, dangle, the good appearance properties such as gloss as the crease-resistant and silk.If with zein fiber and hemp tow blending, then can't spin thin yarn (20tex is following).And hemp fiber blended ratio is high more, and institute's yarn is thick more, is difficult to weave cloister fabric.Hemp fiber blended ratio low excessively (being lower than 20%), then final fabric is difficult to reach the antibiotic health care performance of expection.Therefore, above-mentioned and nonideal method.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of zein fiber good luster of bringing into play is provided, powerful high, good springiness, modulus is higher, biodegradable advantage, it is little to have remedied its moisture absorption, spinnability is poor, no natural antibacterial characteristic, shortcomings such as wearability is relatively poor, the antibiotic of hemp can kept again, moisture absorption is ventilative, under the prerequisite of nice and cool advantage, powerful height with zein fiber, the good characteristics that conformality is good, it is poor to have remedied the hemp drapability, the shortcoming of conformality difference, and can spin the thin yarn, even 10tex following extra fine yarn, captured the difficult problem that hemp is difficult to spin the thin yarn.
Another object of the present invention then is the production method that discloses a kind of above-mentioned zein fiber and regenerative hemp fiber blended antibacterial composite yarn.
According to the technical scheme that invention provides, this antibacterial composite yarn comprises 30～60 parts zein fiber and 40～70 parts regenerative hemp fiber, and unit is a parts by mass; Described regenerative hemp fiber is to be the fiber that raw material regeneration makes with in hemp cast tow, noil, hemp stalk, the stalk core one or more.
The production method of above-mentioned zein fiber and regenerative hemp fiber blended antibacterial composite yarn comprises:
A, raw material prepare: 30～60 parts zein fibers and 40～70 parts regenerative hemp fiber are passed through opening picking, comb and parallel cotton fibers prior to spinning, also standby after the operation in advance respectively successively; Unit is a parts by mass;
To the zein fiber opening picking time, the card wire drum speed is controlled at 600～700r/min, and hired roughneck's speed is controlled at 800～900r/min;
To the regenerative hemp fiber opening picking time, the card wire drum speed is controlled at 500～600r/min, and hired roughneck's speed is controlled at 700～800r/min;
When zein fiber is carried out comb and parallel cotton fibers prior to spinning, its cylinder rotating speed is controlled at 280～330r/min, the licker-in rotating speed is controlled at 600～850r/min, cylinder is controlled at 2～2.5 with licker-in linear resonance surface velocity ratio, simultaneously feed plate is raised 1～2mm, increase spacing of feed plate and licker-in, increase the differential surface speed of licker-in and cylinder, dwindle spacing of doffer and cylinder;
When regenerative hemp fiber is carried out comb and parallel cotton fibers prior to spinning, its cylinder rotating speed is controlled at 280～330r/min, the licker-in rotating speed is controlled at 600～850r/min, cylinder is controlled at 2～2.5 with licker-in linear resonance surface velocity ratio, simultaneously feed plate is raised 1～2mm, increase spacing of feed plate and licker-in, increase the differential surface speed of licker-in and cylinder, dwindle spacing of doffer and cylinder;
B, will be pre-and after zein fiber and regenerative hemp fiber successively through obtaining the blended antibacterial composite yarn of zein fiber and regenerative hemp fiber behind drafting, rove, spun yarn, the winding procedure.
In opening and cleaning step, the hired roughneck adopts kirschner beater or composite type hired roughneck; Mixing in doubling step will " heavily pressurization, in quantitatively, low velocity ", back area draft spins greatly than cotton textiles, forward pull drawing-off and backward pull drawing-off are all spun little than cotton textiles, approximate 1, increasing machine backward pull; The rove operation " is spaced greatly, heavily pressurization ", suitably strengthens the twist factor of rove simultaneously.Spinning process is noted the type selecting and the selection that becomes twist per unit of steel traveler, and twist factor is 330-380, and steel traveler speed is unsuitable too high, and selects suitable steel traveler weight.This regenerated fiber is compared with former hemp fiber, has kept also possessing the performance of viscose outside the good characteristic of former hemp, can control good, the biodegradable and low price of spinnability, hygroscopicity and dyeability as required as fineness and length.Fabrics feel soft, no prodding and itching feeling, comfortable and easy to wear, but stiffness and wrinkle resistance are poor slightly.
Above-mentioned opening picking, comb and parallel cotton fibers prior to spinning, in advance also, operation such as drafting, rove, spun yarn, winder in " cotton spinning ", " the cotton spinning handbook all is documented.
The present invention adopts zein fiber and the regenerative hemp fiber blended antibacterial composite yarn of making.
Utilize zein fiber and regenerative hemp fiber to carry out blending, be made into integrate antibiotic, health care, biodegradable, frivolous, soft, dangle, the novel fabric of premium properties such as conformal, crease-resistant and color and luster are beautiful.This series products is fit to make fashionable dress, leisure wear, suit, shirt and household textiles etc.The special performance of this lining is not the simple superposition of two kinds of fiber advantages.He must be according to the final products needs, rational proportion, the structure of optimal design yarn and fabric, working process parameter etc.The comprehensive function of two kinds of fibrous physics and chemical property has produced the style and features and the performance of required product.
This diversification fibrous raw material structure is utilized the complementation of regenerative hemp fiber and zein fiber performance on the one hand, has improved and optimized the performance of zein fiber product, abundant, as to expand product pattern, style.Remedied the high deficiency of present zein fiber price on the other hand.What is more important adopts zein fiber and regenerative hemp fiber blended, can spin out the thin yarn, even the extra fine yarn below the 10tex, has captured the difficult problem that hemp is difficult to spin the thin yarn.Utilize this yarn can make the lining of frivolous softness, no prodding and itching feeling.
Each road spinning process principle is as follows
(1) blending ratio
The performance and the terylene of zein fiber are approaching.Regenerative hemp fiber and viscose are similar.Therefore, adopt zein fiber and regenerative hemp fiber blended at high proportion, improved the spinnability of zein fiber, improved the sucting wet air permeability and the anti-microbial property of zein fiber lining, reduced production cost.Adopt regenerative hemp fiber and corn fiber blending at high proportion, overcome the DIMENSIONAL STABILITY and the relatively poor weakness of wrinkle resistance of hemp and regenerative hemp fiber lining, improved the high-grade style of dress of lining.In view of mentioned above principle, the corn fiber blending ratio is no less than 30 parts, and regenerative hemp fiber blended ratio is no less than 40 parts, both guaranteed the appearance property of lining, as wrinkle resistance, DIMENSIONAL STABILITY, scraping property very, improve the health comfortableness of lining again,, antibiotic health care ventilative as moisture absorption.Simultaneously, embody the environmental protection theory.
(2) opening and cleaning step
I zein fiber blow room system
The length regularity of zein fiber better, have better elastic, contain assorted few.But regain is low, hygroscopicity is relatively poor, and slight static is arranged, and fusing point is low, and fiber is very fluffy after the shredding, is easy to generate sticking volume.Because fiber has bigger elasticity, under the effect of pressure the elongation of lap bigger, its retraction is also very big under the relaxed state, is easy to generate negative the elongation, the elongation of lap reaches-1.56%.Inherent quality and presentation quality for the assurance lap suitably reduce each speed, the technological principle of employing " duty is grabbed less and grabbed, how pine is few beats, gently combs and lack to fall ", and the three-blade beater removes blade, and each one spaces and should suitably amplify.Must take preventing viscosity step, reduce sticking volume phenomenon.Main hired roughneck adopts kirschner beater or composite type, and hired roughneck's speed will be hanged down than the terylene spinning.
Preferable, blow room system is in the described spinning process: lap is done and quantitatively is no less than 400g/m, cotton rolling weight about 13kg, card wire drum speed 600～700r/min, three wings card wire or comprehensive hired roughneck 800～900r/min.Opener hired roughneck and to give spacing between the cotton roller be 10～12mm, it is 16 * 18 * 20 * 22.5mm that hired roughneck-dust removing bar spaces, scutcher hired roughneck and to give spacing between the cotton roller be 8～10mm, hired roughneck-dust removing bar spaces and is (11～15) mm * (20～22) mm.
II, regenerative hemp fiber blow room system
Regenerative hemp fiber is the same with viscose, and powerful low, the resilience of fiber is poor, and regain is higher, have fibre uniformity good, do not contain assorted characteristics, mainly based on shredding, reduce strike at cotton cleaning process to fiber as far as possible, avoid causing the generation of short flannel.So adopt " with comb generation beat, many combs lack to fall, fully mixed " technological principle.The hired roughneck uses card wire formula or composite type instead, and the three-blade beater removes blade, gives space the relaxing of cotton of cotton roller to the hired roughneck, and hired roughneck's speed will be lowerd, and slows down 15～30% during generally than textile spinning.Dirt rod angle is wanted furnishing and a little bit smaller or anti-dirt rod of adorning of hired roughneck's gyratory directions angle.Also will prevent the lap adhesion simultaneously, the pressurization of pressing the roller two ends weighs 20～40% in the time of will spinning cotton textiles.In order to prevent the generation of static, require to keep relative humidity big, generally be controlled at 65～70%.
(3) carding step
I zein fiber carding process
Because zein fiber has better elastic and elastic return, fiber fluffy, so carding step should adopt the technological principle of " many combs few fall ", each one spaces should bigger grasp, adopts the technology close with terylene to produce.Consider that cotton type feed plate is bigger to the damage of fiber, therefore feed plate is raised 1～2mm.Increase spacing of feed plate and licker-in, suitably reduce licker-in speed, reduce the damage of fiber.The setting that size is leaked the end, mote knife is a purpose with the rate that reduces to fall.Suitably inlet/outlet spaces at the bottom of the little leakage of control, reduces noil.Increase the differential surface speed of licker-in and cylinder, dwindle spacing of doffer and cylinder, help fibre migration.Suitably strengthen cylinder and space, control the combing of fiber well, the reduction cotton knot with cover plate.Mainly solve comb and parallel cotton fibers prior to spinning slivering difficulty, stifled inclined tube problem, improve the transfer ability of fiber.
Preferable, blow room system is in the described spinning process: weight of card sliver spins the quantitatively light of cotton; The cylinder rotating speed is 280～330r/min, and the licker-in rotating speed is 600～850r/min, and cylinder is 2～2.5 with licker-in linear resonance surface velocity ratio, and cover plate speed is got the deep low gear speed of used type, as FA201B card flat minimum rate of accumulation speed 90mm/min.Doffer's rotating speed is 6～36r/min.Feed plate-licker-in and cylinder-cover plate etc. space all cotton big than spinning.Guarantee that institute's carded sliver cotton knot that spins is few, the smooth in appearance exquisiteness, cotton net sharpness is good.
II regenerative hemp fiber carding process
Low, the easy brittle failure of regenerative hemp fiber brute force, in order to reduce the damage of fiber, the speed configuration of cylinder, licker-in and cover plate is low, and spacing in the time of will spinning cotton between cylinder and cover plate is big, mote knife spaced amplify or remove mote knife.Web tension force aspect is grasped aborning at random, with general chemical fibre less than what big difference, the phenomenon that web tenesmus or web fall the limit can too much not appear.Web tension force is bigger, improves fibre migration rate and cotton net sharpness.Relative humidity generally is controlled in 60～65% scopes.
Preferable, blow room system and zein fiber are approaching in the described spinning process, only need to do suitably to adjust to get final product.
(4) mixing in doubling step
For degree of stretching and the separating degree that guarantees ripe middle fiber, improve ripe bar evenness, correct control quantitatively makes blending rate up to specification, adopt zein fiber and regenerative hemp fiber pre-respectively and after mix through three roads again and technology.
Relatively poor at zein fiber electric conductivity, characteristics such as fiber fluffy, mixing in doubling step adopt " heavily pressurization, in quantitatively, low velocity " technological principle, reduce " three around " and clogging in producing.Drafting speed is too not high.Because there is the difference of elastic elongation aspect in two kinds of fibers of blending, when head and drawing-off under the effect of drafting force elongate fiber, under relaxed state after two parallel operation, zein fiber is because retraction appears in its flexible effect.Length difference appears in regenerative hemp fiber behind this model machine in the strip and zein fiber, sliver is rived, and causes automatic stop behind two cover feedings, the machine.By strengthening the machine backward pull, the angle of guide strip rack and sliver has increased frictional force behind the adjusting machine, makes and drives normally.
Preferable, the drawing process parameter configuration is in the described spinning process: ripe is quantitatively light partially; Back area draft spins greatly than cotton textiles, and forward pull drawing-off and backward pull drawing-off are all spun little than cotton textiles, approximate 1.
(4) rove operation
Do deterioration for preventing the bar that misdraft brings, adopt the technological principle of " spacing greatly; heavily pressurization " in the rove operation, suitably strengthen the twist factor of rove simultaneously, in the time of so both can having guaranteed that rove was shaped with the spun yarn unwinding, be unlikely generation misdraft, help the control of fiber in the spun yarn back area draft again.But note avoiding spun yarn to go out " hardhead " phenomenon.
Preferable, rove operation main technologic parameters configuration in the described spinning process: twist factor (56～86) is littler than cotton spun yarn, the grasp bigger than normal of cushion rubber jaw, and the roller pressurization is big than cotton spinning.
(5) spinning process
Spinning process is noted the type selecting and the selection that becomes twist per unit of steel traveler, the resultant yarn twist factor 350 of stocking yarn, woven yarn is about 370～380, because zein fiber has lower fusing point, steel traveler speed is not declared too high, and select suitable steel traveler weight to prevent to produce filoplume, to guarantee the quality of resultant yarn.
Preferable, spinning process main technologic parameters configuration in the described spinning process: twist factor is 330～380; Roller is pressurised into (14～18) * (10～14) * (14～18) daN, and is all big than cotton spinning; Nip gauge is about 2.5mm, grasp less than normal; The first break draft multiple is (1.14～1.50), and is big than cotton spinning; The total draft multiple can bigger than normally be grasped.
The invention provides a kind of zein fiber and regenerative hemp fiber blended complex yarn, can be made into this yarn integrate that antibiotic health care, biodegradable, moisture absorption are ventilative, frivolous softness, dangle, the novel fabric of premium properties such as conformal, crease-resistant and color and luster are beautiful.The present invention has given full play to zein fiber good luster, powerful height, good springiness, higher, the biodegradable advantage of modulus, shortcoming such as remedied that its moisture absorption is little, spinnability is poor, no natural antibacterial characteristic, wearability are relatively poor.Also can be under the prerequisite of the advantage that antibiotic, the moisture absorption that keep hemp are breathed freely, felt nice and cool, powerful height with zein fiber, the good characteristics that conformality is good, remedied hemp and the regenerative hemp fiber fabric fall is poor, the shortcoming of conformality difference, and can spin the thin yarn, even the following extra fine yarn of 10tex, capture the difficult problem that hemp is difficult to spin the thin yarn.Utilize this yarn can weave the lining of frivolous softness, no prodding and itching feeling.
