Description

Flat multifilament-yarn textile
Technical field
The present invention relates to flat multifilament-yarn textile.Particularly, the present invention relates to comprise the Woven fabric of polyfilament yarn, polyfilament yarn is made of a plurality of rayon monofils with flattened cross-sectional profile, the every side of monofilament partly has two or more contraction flow regions, and present soft feel, in fact high water imbibition, abrasion resistance and anti-perspectivity.
Background technology
Current, sportswear and uniform adopt the Woven fabric of dissimilar gas permeability deficiencies.As the low-permeable Woven fabric, be well known that the high density Woven fabric that forms by synthetic fiber, for example, polyester or polyamide fiber and on Woven fabric, be formed with the Woven fabric of resin-coated coating Woven fabric and calendering.
Yet high density Woven fabric, the Woven fabric of face coat and calendering have low pliability (hard feel) usually, and the surface of fabric presents low resistance to wearing (mar proof), and like this, the Woven fabric of these types must improve.
Synthetic fiber, for example, polyester and polyamide fiber have splendid physics and chemical property, and in fact it has different purposes, for example clothes and industrial use.In fact, polyester fiber presents splendid mechanical strength, DIMENSIONAL STABILITY and easy-care properties, like this, but by for example dissimilar Woven fabric extensive use that forms of polyester fiber of synthetic fiber.
Yet, except having above-mentioned advantage, by synthetic fiber for example the Woven fabric that forms of polyester fiber have the high grade of transparency.Like this, when high grade of transparency synthetic fiber form fabric, and fabric like this, can find under the upper garment to be the problem that there is clothing wear in underwear when being used as upper garment.
As address the above problem a kind of method, be well known that fine inorganic particle for example titanium dioxide granule be distributed in the synthetic fiber.The synthetic fiber that this method causes generating present the opacity increase, have strengthened anti-perspective performance like this.Yet the Woven fabric that is formed by opaque synthetic fiber still must have the weaving density of increase, and with the gap that prevents to form between the light transmission yarn, Woven fabric is formed by this yarn.The increase of weaving density brings the Woven fabric of generation to present the problem that pliability reduces.
As indoor material, for example under the situation of curtain, the anti-perspective performance (promptly anti-vision is seen through a kind of goods and people in the indoor performance of walking about) and the penetrability of light must be very high at Woven fabric.Yet usually, these performances are mutually internally inconsistent, like this, are difficult to realize together.
For this reason, usually, thin curtain lace is arranged in reveal, and the thick curtain that dangles is arranged in the indoor, and at night, the curtain that dangles is pulled on, and by day, curtain lace is pulled on, to satisfy the requirement of anti-perspective and printing opacity.Yet in general, thick suspension curtain has the light transmission of splendid anti-perspective and difference, and thin curtain lace not only also has anti-fully inadequately perspective performance by day at night.Therefore, be necessary to address this problem.In order to address this problem, for example, a kind of resistance optical window curtain is disclosed in Japan Patent 3167586, it is formed by compound Woven fabric, this compound Woven fabric comprise include matting agent for example titanium dioxide the polyester fiber yarn and comprise black pigment and reflecting and light absorbing black polyester fiber yarn; A kind of mirror curtain is for example disclosed in Japanese unexamined patent publication No. open file 2000-237036, it makes fabric or the knitting fabric of making forms by woven, on one side surface or both side surface, be provided with Woven fabric zero diopter gloss yarn, this curtain has high preventing and sees through indoor performance from the outside through curtain, this is to produce scattering because of the time on the zero diopter glossy surface that is mapped to Woven fabric when illumination, and this curtain also has gratifying light transmission and gas permeability; For example in Japanese unexamined patent open file 62-133787, disclose a kind of resistance light Woven fabric, wherein on a surface of Woven fabric, formed the black light shield layer.
Be formed with the above-mentioned resistance light Woven fabric of black light shield layer and the problem of resistance optical window curtain and be that light transmission is poor on the Woven fabric surface, band curtain house interior is darker, thereby forms languorous environment in band curtain room.And, the light transmission height of mirroring curtain.Yet the problem of mirroring curtain is that the anti-perspectivity of mirroring curtain is particularly abundant inadequately in the possible time, and zero diopter gloss yarn produces bright-coloured gloss on the mirroring curtain.
As mentioned above, have sufficient light transmission and splendid anti-see through performance and can be used for putting into practice in Woven fabric also do not exist.
And the Woven fabric of being made by synthetic fiber is disadvantageous, because the water imbibition of synthetic fiber Woven fabric, particularly absorption of perspiration is than by the natural fabric Woven fabric made of cotton fiber poor for example.
As the water imbibition that strengthens the synthetic fiber Woven fabric and a kind of means of absorption of perspiration, a kind of suction Enhancement Method that water absorbing agent is used for Woven fabric is known.And, for example using shirt, when sportswear and uniform, need further to improve suction and absorbing sweat performance,
In these cases, press for the artificial fibre Woven fabric, particularly have soft, high anti-perspectivity and splendid suction and the synthetic fiber Woven fabric of absorption of perspiration.

If the quantity of jut is 2 or still less, the quantity of contraction flow region is 1 or still less, then the periphery of the monofilament of Xing Chenging shows as frictional resistance increases, like this, the mutual cross section of warp parallel at Woven fabric, in this part, the compression stress of warp and parallel interacts, the slip of monofilament is scattered abundant inadequately, the very difficult control that the gas permeability of the Woven fabric of formation becomes, and the ABRASION RESISTANCE of the Woven fabric of formation is abundant inadequately, contraction flow region quantity reduces water imbibition and the absorption of perspiration deficiency cause the Woven fabric that forms, and the light scattering effect deficiency of monofilament periphery, like this, the Woven fabric of formation presents not satisfied anti-seeing through property.
In flat multifilament-yarn textile of the present invention, the cross sectional planes degree (B/C1) of the monofilament of flat polyfilament yarn is 2 to 6, is preferably 3 to 5.If the cross sectional planes degree is less than 2, the flexing resistance of monofilament (rigidity) is too high, and then the Woven fabric of Xing Chenging presents not enough pliability, like this, can't obtain the target soft feel of Woven fabric.
And, when the cross sectional planes degree less than 2 the time, in the mutual cross section of warp parallel of Woven fabric, because warp and parallel compression stress each other, the slip of the monofilament in polyfilament yarn is scattered abundant inadequately, and the gap between warp and the parallel can not be fully little, and the bulk between the silk can not be enough little, like this, the gas permeability of the Woven fabric of formation is difficult to control to desirable level.
And the monofilament that has greater than 6 cross sectional planes degree (B/C1) is difficult to make.
In the cross-sectional profile of the flat monofilament of the flat polyfilament yarn that can be used for Woven fabric of the present invention, in the direction vertical with the longitudinal centre line of flat appearance, the ratio (C1/C2) of Breadth Maximum (C1) and minimum widith (C2) is preferably in 1.05 to 4.00 the scope, is more preferably between 1.10 to 2.50.Above-mentioned ratio (C1/C2) is the parameter relevant with the contraction flow region degree of depth of flat monofilament.If ratio (C1/C2) is less than 1.05, promptly the degree of depth of contraction flow region is too little, then, the outer surface of the flat monofilament that forms can present too high frictional resistance, the Woven fabric that forms can present too high gas permeability and not enough ABRASION RESISTANCE, anti-seeing through property and water imbibition and absorption of perspiration.And, if ratio (C1/C2) is greater than 4.0, the contraction flow region degree of depth of flat monofilament is too big, the effect of contraction flow region is saturated, the Woven fabric that forms may be disadvantageous, because the wire shaping technology potentially unstable, the monofilament of formation can slide along contraction flow region, and the uniformity of the cross-sectional profile of monofilament may reduce.
In each accompanying drawing of Fig. 2 and 3, represented to be not useable for another embodiment of cross-sectional profile of the flat monofilament of flat multifilament-yarn textile of the present invention.
The cross section of silk 1 shown in Figure 2 has a kind of profile, compared to Figure 1, with respect to longitudinal centre line 2, this profile has similar jut and the contraction flow region that forms in two side parts, the arch that presents the ellipse of the oval main shaft stretching, extension in edge except the profile of jut shown in Figure 2, the oval arch of Xing Chenging is milder than the dome-shaped of the jut of Fig. 1 like this, and like this, the degree of depth of the contraction flow region of Fig. 2 is compared less with Fig. 2.
The cross-sectional profile of silk 1 shown in Figure 3 has jut and contraction flow region, and this jut and contraction flow region partly form with respect to two sides of longitudinal centre line in flat appearance, and is 4 and 3 at each sidepiece dosis refracta of flat appearance respectively.In Fig. 3, jut 3a is than the width of other 3 juts 3 and highly littler, and like this, the degree of depth of the contraction flow region 4a that forms in the two side portions of jut 3a is promptly little than the degree of depth of other contraction flow region 4 to the bottom of contraction flow region 4a from the top of jut 3a.
As mentioned above, the cover factor of flat multifilament-yarn textile in from 800 to 3500 scope, performance and the character necessary, definite above-mentioned scope that can be suitable according to Woven fabric.
The cover factor of Woven fabric (CF) is defined by following formula.

In an embodiment of flat polyfilament yarn of the present invention, the weaving density of the thickness of warp and parallel and warp and parallel is controlled at the degree of cover factor in from 1500 to 3500 scope of the Woven fabric of generation.
In embodiments of the invention (1), the cover factor of Woven fabric is in from 1500 to 3000 the scope preferably, is preferably in 1500 to 2500 the scope.
And in embodiments of the invention (1), flat polyfilament yarn better has the twisting count that adds of 0 to 2500 circle/rice, better has the twisting count that adds of 0 to 600 circle/rice, and best 0 circle/rice does not promptly have twisting.
In embodiments of the invention (1), flat multifilament-yarn textile better has 5ml/cm 2Sec or littler gas permeability better have 4ml/cm 2Sec or littler gas permeability preferably have 0.1ml/cm 2Sec to 3ml/cm 2The gas permeability of sec.Gas permeability is according to JIS L 1096- 1998, 6.27.1, method A (utilizing Frazir type testing machine) determines.
In embodiments of the invention (1), flat multifilament-yarn textile better has 40mm or bigger absorption speed, better has 50 to 70mm absorption speed, and this is according to JIS L1096- 1998, 6.26.1, (2) method B (Byreck method) is definite, and, better have 50 abrasivenesses or higher abrasion resistance, better have 80 abrasivenesses or higher abrasion resistance, preferably have 100 abrasivenesses or higher abrasion resistance.
In embodiments of the invention (1), if the cover factor of Woven fabric (CF) less than 1500, the gap area that forms between warp and parallel may be too big, the Woven fabric of generation may present too high gas permeability (for example greater than ml/cm 2And not enough ABRASION RESISTANCE sec) and not enough suction and absorption of perspiration.And, if the cover factor of Woven fabric (CF) is greater than 3500, then the warp in the Woven fabric of Sheng Chenging may closely contact mutually with parallel, the Woven fabric that generates may have not enough soft feel, too high flexing resistance, like this, it is unsatisfactory that the feel of Woven fabric may become, and the ABRASION RESISTANCE of Woven fabric may be abundant inadequately.
In the flat multifilament-yarn textile with cover factor of 1500 to 3500 of embodiments of the invention (1), because the warp weft intersections at Woven fabric is divided the compression stress that produces, the warp of formation Woven fabric and/or the flat polyfilament yarn of parallel are more flat, and it is extending transversely, flat monofilament is in contact with one another in its flat periphery under this compression stress, and laterally slide mutually, so that make yarn flat.In the yarn of this flattening, the area decreases in the gap between warp and the parallel, like this, the Woven fabric of generation presents the gas permeability of reduction.Therefore, the flat multifilament-yarn textile of embodiments of the invention (1) preferably presents 5ml/cm 2Sec or littler low-permeable.
In embodiments of the invention (1), the Woven fabric that the flattening of flat polyfilament yarn causes generating presents the flexing resistance reduction, and pliability increases, good soft feel.And, in the Woven fabric of embodiments of the invention (1), each flat monofilament in polyfilament yarn partly has along peripheral longitudinally extending 3 or more juts in each side of its flat appearance, and 2 or more contraction flow regions between jut, forming, like this, the periphery of flat monofilament becomes coarse.Like this, when the monofilament in the yarn was in contact with one another, particularly under the effect of the compression stress that the intersection of warp and parallel produces, the contact area of the monofilament that is in contact with one another was less, and like this, the frictional resistance between the monofilament is littler.Therefore, the periphery of the roughening of monofilament helps to strengthen the pliability of the Woven fabric of generation.And even when the periphery of monofilament is in contact with one another, in the periphery of each monofilament, the peripheral longitudinally extending contraction flow region in edge does not have or does not have close basically.Therefore, because capillarity, water or sweat are easy to spread along contraction flow region, and like this, the Woven fabric of generation presents splendid suction and absorption of perspiration.
The flat multifilament-yarn textile of embodiments of the invention (1) presents splendid soft feel, high suction and absorption of perspiration and high ABRASION RESISTANCE, so of great use as the low-permeable textile material of different garment, different garment for example is a sportswear, men and women's uniform, and national costume (national clothes), for example tabes, underwear, shirt, cap, the Woven fabric of umbrella and sunshade.
In an embodiment (2) of flat multifilament-yarn textile of the present invention, polyfilament yarn comprises mass content 0.2% or higher matting agent, be more preferably and comprise mass content, preferably comprise mass content at 1.0 to 2.5% matting agent at 0.4 to 3.5% matting agent.The cover factor of Woven fabric (CF) in from 1300 to 3000 scope, best 1400 to 2500.
The composition of the matting agent that comprises in the polyfilament yarn for the flat multifilament-yarn textile of embodiments of the invention (2) and type without limits, as long as can obtain target Woven fabric of the present invention.Usually, matting agent can comprise the thin inorganic particle of at least a type, for example titanium dioxide and barium surface.The gross mass of opportunity multifilament, if the mass content of matting agent less than 0.2%, the polyfilament yarn of generation can present not enough reflectivity, like this, the Woven fabric of generation may not show the gratifying anti-vision property understood thoroughly.Should note if the mass content of matting agent greater than 7%, it is unstable that the formation fibroid of the component of polymer of generation may become.
If the cover factor (CF) of the Woven fabric of embodiments of the invention (2) is less than 1300, the gap area that forms between warp and parallel may be too big, and the Woven fabric of generation may present unsafty anti-perspectivity.And, if the cover factor of Woven fabric (CF) greater than 3000, then the Woven fabric of Sheng Chenging may present not enough flexibility and unsafty feel.
Woven fabric at embodiments of the invention (2) has under the situation of plain weave structure, and the cover factor of plain weave fabric (CF) is preferably in from 1400 to 1800 scope, is more preferably in from 1500 to 1700 scope.
Woven fabric at embodiments of the invention (2) has under the situation of twill structure, and the cover factor (CF) of the twill weave fabric of generation is preferably in from 1900 to 2400 scope, is more preferably in from 2000 to 2300 scope.
The twisting count that adds for the polyfilament yarn of the Woven fabric that can be used for embodiments of the invention (2) does not have particular restriction, as long as can obtain target Woven fabric of the present invention.Yet, moving freely relatively in order to guarantee the monofilament in the yarn fully, the twisting count that adds of flat polyfilament yarn is preferably 0 to 1500 circle/rice, better is 0 to 600 circle/rice, is preferably 0 circle/rice, does not promptly twist.
In embodiments of the invention (2), flat multifilament-yarn textile preferably has certain anti-see-through, and in the L*a*b colour system, the anti-see-through of this Woven fabric is with difference DELTA L (=L* w-L* b) expression, this difference AL is 15 or littler, better is 10 to 13, difference DELTA L is with L* wThe expression the L* value that places the Woven fabric on the blank and with L* bThe L* value that places the Woven fabric on the blackboard poor of expression.If anti-see-through Δ L then may be not enough in anti-the seeing through property practice of the Woven fabric of Sheng Chenging greater than 15.
In embodiments of the invention (2), flat multifilament-yarn textile better has 40mm or bigger absorption speed, better has 45mm or bigger absorption speed, preferably has 50 to 70mm absorption speed, and this is according to JIS L 1096- 1998, 6.26.1, (2) method B (Byreck method) determines.If present not enough suction and absorption of perspiration in the Woven fabric practice that absorption speed less than 40mm, then generates.
In the flat multifilament-yarn textile of embodiments of the invention (2), the cross-sectional profile that constitutes the monofilament of flat polyfilament yarn is flat.In this flattened cross-sectional profile, partly be formed with three or more juts and the two or more contraction flow regions between jut in each side of flat appearance.Like this, the periphery of the monofilament that is in contact with one another presents low mutual frictional resistance, and can slide mutually easily.When compression force was on polyfilament yarn, monofilament can easily relatively move along the contact periphery, and therefore, the polyfilament yarn flattening is also extending transversely.And monofilament is closely contact mutually in flat periphery, so that the gap between the yarn of arranging in the Woven fabric is reduced, and reduces through the light quantity of Woven fabric transmission.And the mass content that comprises in monofilament is that 0.2% matting agent reduces the light through the Woven fabric transmission that generates, and makes the light reflection brokenly on Woven fabric that shines on the Woven fabric.And, place a plurality of juts of formation and the peripheral roughening that contraction flow region causes monofilament at monofilament outer, so that make the incident light scattering, and prevent to see through Woven fabric.In the intersection of the warp and the parallel of Woven fabric, the flat and distribution of polyfilament yarn causes the intersection softness, and the feel of the Woven fabric that generates is more soft.
And the contraction flow region that stretches along the longitudinal axis of monofilament makes the water and the sweat generation capillarity of generation, and the Woven fabric that generates presents high suction and absorbing sweat speed.
Like this, the flat multifilament-yarn textile of embodiments of the invention (2) is being used for for example shirt as textile material of great use, and when sportswear and uniform, it has high anti-seeing through property and the suction absorption of perspiration is necessary.
In an embodiment (3) of flat multifilament-yarn textile of the present invention, the rayon monofil of polyfilament yarn comprises mass content at a spot of matting agent of 0 to 0.2%.The cover factor of Woven fabric is in from 800 to 2000 scope.
The mass content of the matting agent among the rayon monofil is 0 to 0.2%, is 0 to 0.1% preferably.Be more preferably, do not contain matting agent in the monofilament.Matting agent of the present invention can be selected from traditional matting agent, for example titanium dioxide and barium surface.If the quality of matting agent is greater than 0.2%, in the preferable use of the Woven fabric of embodiments of the invention (3), curtain for example, the Woven fabric of generation can present not enough light transmittance, has unsafty illuminating property like this.
In the flat multifilament-yarn textile of embodiments of the invention (3), polyfilament yarn is preferably the twisting count that adds with 0 to 1000 circle/rice, is more preferably 0 to 200 circle/rice, preferably not twisting.
The cover factor (CF) of the flat multifilament-yarn textile of embodiments of the invention (3) is preferably in from 80 to 200 scope, is more preferably from 900 to 1800 preferably from 1000 to 1800.
In the best use of the flat multifilament-yarn textile of embodiments of the invention (3) for example in the curtain, if cover factor (CF) is less than 800, gap area between Woven fabric middle longitude and parallel may be too big, and the Woven fabric of generation may present unsafty anti-perspectivity.And, if the cover factor of Woven fabric (CF) greater than 2000, then the Woven fabric of Sheng Chenging may present not enough illuminating property.
The flat multifilament-yarn textile of embodiments of the invention (3) preferably presents 10 to 70% light transmittance, and is better 20 to 50%, and this is according to JIS L 1055- 1987, 6.1, method A determines to have the illuminance of 1000001x.The light transmittance of representing in percentage calculates by the light resistance rate with percentage that deducts Woven fabric from 100%.If light transmittance is less than 10%, for example in the curtain, the illuminating property of the Woven fabric of generation may be not enough in the preferable use of Woven fabric.And, if light transmittance greater than 70%, the Woven fabric of generation may present not enough anti-perspectivity.
The flat multifilament-yarn textile of embodiments of the invention (3) is preferably colourless, or is coloured to light color or moderate color.The type of the pigment that is used to dye and quantity can be determined according to the purposes and the necessary performance of the Woven fabric of the dyeing that generates.
In the flat multifilament-yarn textile of embodiments of the invention (3), flat multifilament divides extending transversely and flattening in the warp weft intersections of Woven fabric, this is because due to the compression force of this intersection generation, monofilament is closely contact mutually in its flat periphery, to form compact texture.In this compact texture, the gap between warp and the parallel is very little, through the light quantity minimizing in this gap., interfere mutually near light mutually, in little gap inscattering through a spot of light in this gap to strengthen the anti-perspective effect of Woven fabric through the transmission in too small gap.And, with have the flattened cross-sectional profile and be provided with level and smooth periphery the silk, silk with circular cross section profile, compare with silk with triangular cross section profile, the special cross-sectional profile of the flat monofilament in polyfilament yarn causes the periphery at monofilament, incident light random scatters, and the anaclasis increase that sees through silk.Like this, the Woven fabric of generation presents splendid anti-perspectivity, and can not reduce its illuminating property.
The flat multifilament-yarn textile of embodiments of the invention (3) presents good soft feel, low flexing resistance, and low-permeable, and high-wearing feature, this and embodiment (1) and (2) are similar.
Because above-mentioned reason, the flat multifilament-yarn textile of embodiments of the invention (3) prevents for example curtain of material for indoor anti-perspective, and roll-up shutter (curtain) and spacer are of great use.
