FIG. 1 is a side view of the entangled yarn in one embodiment of the present invention. FIG. 2 is a schematic explanatory view of a method for producing a long fiber air entangled yarn according to an embodiment of the present invention. FIG. 3 is a photograph of a fabric sample of an antistatic winter clothing item according to an embodiment of the present invention.

The present invention is an antistatic winter clothing product containing a long fiber batting between the outer material and the lining. At least one of the outer and lining fabrics and the long fiber batting contains conductive fibers. Further, the antistatic winter clothing of the present invention is an antistatic winter clothing containing long fiber batting between the outer material and the lining, and the fabric of at least one of the outer material and the lining and the long fiber batting are made of conductive fibers. including. As a result, it becomes a winter clothing product with high antistatic properties (antistatic properties). For antistatic wear products, the amount of antistatic charge is preferably 0.4 μC / arrival or less, more preferably 0.23 μC / attachment, as measured in accordance with JIS T8118: 2001 (Antistatic test for antistatic work clothes). It is as follows.

It is preferable that conductive fibers are partially arranged on at least one of the warp and weft that constitutes at least one of the outer material and the lining. The partial arrangement preferably means that at least one of the warp and weft yarns is arranged as 1 to 10 yarns per inch (25.4 mm), for example. When long fiber batting is contained between the outer material and the lining, it is most preferable that both the outer material and the lining contain conductive fibers. Conductive fibers include metal fibers, carbon fibers, fibers in which metal particles and carbon particles are kneaded, and fibers using a conductive polymer. For example, there are "Bertron" (registered trademark) antistatic yarn manufactured by KB Seiren Co., Ltd. and "Kuracarbo" (registered trademark) antistatic yarn manufactured by Kuraray Co., Ltd.

The batting (also referred to as stuffing yarn) of the present invention is composed of at least two types of long fibers A and long fibers B. It is optional to add fibers other than the long fibers A and the long fibers B, but when the batting is 100% by mass, the total of the long fibers A and the long fibers B is preferably 70% by mass or more, more preferably 80% by mass or more. Is. The long fibers A and the long fibers B are integrated. Here, "integration" means a state in which fibers are entangled or wound with each other. The long fiber A is relatively shorter than the long fiber B. By providing a difference in length between the long fibers A and the long fibers B, bulkiness can be obtained.

The conductive fibers of the batting of the present invention are preferably contained only in the long fibers A. The long fiber A is relatively shorter than the long fiber B and is effective in preventing antistatic. The long fiber A preferably contains conductive fibers in an amount of 10% by mass or more and 100% by mass or less. Specifically, it is preferable that the long fibers A use 100% by mass of conductive fibers or contain 10% by mass or more and less than 100% by mass of conductive fibers. Particularly preferably, it is 15% by mass or more and 50% by mass or less. Within the above range, the antistatic function can be exhibited. When the conductive fiber is 10% by mass or more and less than 100% by mass, the conductive fiber yarn and the ordinary yarn (for example, the polyester yarn used as the long fiber B below) are aligned, entangled, and combined. Integrate with. Conductive fibers include metal fibers, carbon fibers, fibers in which metal particles and carbon particles are kneaded, and fibers using a conductive polymer. For example, there are antistatic yarn manufactured by KB Seiren Co., Ltd. and antistatic yarn manufactured by Kuraray Co., Ltd. Further, since the long fiber A is relatively shorter than the long fiber B, if the long fiber A contains the conductive fiber thread, the amount of the conductive fiber thread used can be reduced and the cost can be reduced. On the other hand, when the long fibers B contain conductive fiber threads, the bulkiness tends to be low. The ratio of conductive fibers in the batting containing the long fibers A and the long fibers B is preferably about 0.5 to 5% by mass. Within this range, the antistatic function can be exhibited. Further, the obtained batting may be used as a bundle of about 5 to 50 pieces. In this case, it is not necessary to use conductive fibers for the long fibers A of all 5 to 50 battings, and the batting containing the conductive fibers in the long fibers A is, for example, about 3 to 12 for a bundle of 30 fibers. That is, the number of bundles may be about 5 to 40% of the number of bundles. In this case, the ratio of conductive fibers in the bundled body using a plurality of batting is preferably about 0.05 to 0.9% by mass.

As the long fibers A and B, solid yarns (ordinary yarns) such as polyester, nylon, polypropylene, and acrylic can be used, but polyethylene terephthalate (PET) hollow fibers can also be used. The polyethylene terephthalate hollow fiber is warm due to the heat insulating effect, and the PET is firm and can maintain high bulkiness. The hollow ratio is preferably 30%.

The mass per unit length of the batting is preferably 0.01 to 3 g / m, more preferably 0.02 to 1.5 g / m. Within this range, it is convenient to handle when making stuffing.

The long fiber B is preferably 1.1 to 100 times longer than the long fiber A, more preferably 2 to 100 times, and further preferably 4 to 60 times. Within this range, the long fibers B become loop fibers as much as they are long, and can be made bulky.

The long fibers A and the long fibers B are preferably integrated by at least one process selected from entanglement processing, air jet processing, winding processing, and processing of injecting the long fibers B onto the long fibers A. The entanglement process is a process using an air entangler that injects compressed air in a direction perpendicular to the traveling direction of the long fibers A and B. The air jet process is a so-called Taslan process, which is a process of pushing compressed air into the long fibers A and B in the traveling direction. The winding process is a process in which the long fiber B is wound around the long fiber A and integrated. The process of injecting the long fibers B onto the long fibers A is a process of injecting the long fibers B onto the long fibers A and entwining them.

The batting is preferably fixed with a smoothing agent. This is to improve productivity. Examples of the smoothing agent include silicone resin and fluororesin. Taking a silicone resin as an example, it is preferable to apply the silicone resin to the batting and heat-fix it by curing. The preferable amount of the silicone resin adhered is in the range of 0.1 to 10% by mass with respect to the batting. Further, an acrylic resin, a urethane resin, an epoxy resin, or the like may be used in combination for adjusting the hardness.

The single fiber fineness of the long fibers A and B is preferably 0.1 to 300 decitex, and the total fineness is preferably in the range of 10 to 600 decitex. More preferably, the single fiber fineness is in the range of 1.0 to 50 decitex and the total fineness is in the range of 20 to 250 decitex. When the fineness is within the above range, it is hard to settle and the texture is good.

It is preferable that the batting of the present invention is arranged and filled between the outer material and the lining, and is fixed to the outer material and the lining by a plurality of quilt threads sewn in the width direction of the batting. As a result, the length of the batting does not change between the fixed points, and the long fibers A and B are integrated, so that the movement of the batting is restricted even after repeated washing, and the batting is less biased and bulky. It will be an expensive laundry product. In addition, as the batting of the present invention, other long fiber stuffing may be used together with the yarn for long fiber stuffing, and the other long fiber stuffing and the yarn for long fiber stuffing of the present invention are mixed and a plurality of quilted yarns are used. It may be fixed to the side land. In addition, it may be used in combination with other feathers, artificial feathers, and short-fiber cotton.

The batting of the present invention is filled between the outer material and the lining to be worn. As the worn items, gloves, neck warmers, underwear, jackets and other upper clothing, pants, vests, skirts and other underwear, coveralls, heat insulating clothing and the like are preferable. The filling amount of the batting is preferably ^{70 to 110 g / m 2} per 10 cm in length × 10 cm in width. This allows the warmth to be maintained.

As the outer material and lining of the antistatic wear item of the present invention, the fabric used for ordinary wear items can be used. For example, a fabric containing 100% cotton spun yarn, 100% polyester fiber spun yarn, or a blended yarn of cotton and polyester fiber is preferable. In the case of a blended yarn of cotton and polyester fiber, the blended yarn can be blended at a ratio of 10 to 90% by mass of cotton and 90 to 10% by mass of polyester fiber. The fabric is preferably a woven fabric or a knitted fabric. Textiles are particularly preferred. This allows washing and can be used repeatedly.

The woven fabrics applicable to the present invention include plain weave, twill weave, satin weave, change plain weave, change weave, change satin weave, change weave, pattern weave, single layer weave, double structure, multiple structure, and warp. There are pile weave, weft pile weave, twill weave, etc. Knitting includes round knitting, weft knitting, warp knitting, pile knitting, etc. , Denby organization, cord organization, atlas organization, chain knitting organization, insertion organization, etc. Of these, twill fabric is preferable.

The mass (weight) per unit area of the woven fabric or knitted fabric used for the outer material ^{is preferably 50 to 500 g / m 2} , more preferably 100 to 450 g / m ² , and particularly preferably 140 to 400 g / m ² . The basis weight of the lining is preferably about ^{50 to 170 g / m 2.}

This will be described below with reference to the drawings. In each drawing, the same reference numerals indicate the same parts. Further, in the following, the case where the batting is an entangled yarn will be described as an example. FIG. 1 is a side view of a long fiber entangled yarn according to an embodiment of the present invention. In this long fiber entangled yarn 1, the constituent fibers of the core yarn 2 (long fiber A) and the filament 3 (long fiber B) are entwined with each other, and the filament 3 (long fiber B) is partially opened. It forms looped fibers.

FIG. 2 is a schematic explanatory view showing a method for manufacturing an air entangled yarn. The core yarn 4a (long fiber A) is pulled out from the winding yarn body 4, the core yarn 15a (antistatic yarn of the long fiber A) is pulled out from the winding yarn body 15, and the flower yarn 5a (long fiber B) is pulled out from the winding yarn body 5. The two feed rollers 6 and 7 and the thread guide 8 are passed through and supplied to the air entanglement device 10. When the compressed air 11 is supplied to the air entanglement device 10, the fibers in the thread path 9 are entangled with each other by being opened or swirled. Reference numeral 12 is a mixed fiber entangled yarn. The core yarn supply speed is 10 to 200 m / min, the flower yarn supply speed is 20 to 10000 m / min, the winding speed is 10 to 200 m / min, and the air pressure is 0.01 to 1.0 MPa. After the above, the yarn after passing through the delivery roller 13 and the winder roller 14 is wound around the winding body 20. This method has an advantage in that the winding speed of the yarn can be increased to 20 to 1500 m / min and the productivity is high.

The obtained entangled yarn is provided with a silicone resin. As the silicone resin, it is preferable to use a reactive silicone treatment agent having a hydrogen group (-OH), a vinyl group (-CH = CH _{2) or the like at the molecular end.} For example, soft silicones such as "TERON E 530" bulky silicone, "TERON E 731", and "TERON E 722" manufactured by Matsumoto Yushi Pharmaceutical Co., Ltd. can be used. The amount to be applied is preferably 0.1 to 10% by mass with respect to the batting by dry weight. Next, in the heat treatment step, the silicone resin is cured by heat treatment at 140 to 190 ° C. for 1 to 10 minutes.

Hereinafter, the present invention will be described in more detail with reference to Examples. The present invention is not limited to the following examples.
A method for measuring each physical property will be described.
<Charge charge measurement test>
In the charge charge measurement test, antistatic wear samples were measured in accordance with JIS T 8118: 2001 (Antistatic test for antistatic work clothes, tumbler method). In this test, the sample dough is placed in a drum and rotated at 46 rpm for 15 minutes. There are two types of friction cloth on the inner surface of the drum, one lined with an acrylic fiber woven fabric and the other lined with a nylon fiber woven fabric, and each is subjected to a charge charge measurement test. The environmental conditions of the test room were a temperature of 20 ° C. and a relative humidity of 40% RH, and the measurement was performed after JIS L0217 103 method (after repeating home washing 5 times, rinsing with water and drying with tumble for 20 minutes).
<Measurement method for bulkiness>
One of the quality standards for feathers is bulkiness. For feathers, the bulkiness of the batting material (filling yarn) was measured by a method conforming to the JIS feather test method (JIS L 1903-1998, a method for testing feathers for filling materials used in feather products). 30 g of batting material is placed in a cylinder container having an inner diameter of 29 cm and a height of 50 cm, and a 120 g load disk (weight) is placed on the cylinder container for 2 minutes, and then the height of the batting material is measured. Measure 3 points of the weight up to 1mm unit. This value is larger for more elastic and good quality batting material. At this time, 10 or more batting materials (stuffing threads) are bundled, cut to a length of 50 cm, and 30 g is collected. If it does not fit in the measuring instrument, the overflowing batting material (stuffing thread) was lightly pressed by hand to prevent it from overflowing.

(Example 1)
<Batting>
As the core yarn, a conductive fiber, KB Seiren's antistatic yarn, fineness 22decitex, 3 filaments and polyethylene terephthalate filament yarn, fineness 33decitex, 18 filaments are used, and polyethylene terephthalate (PET) hollow as the flower yarn. Using filament yarn (hollow ratio 35%), fineness 39decitex, and 12 filaments, a stuffing yarn was prepared under the conditions shown in Table 1. The conductive fibers in the core yarn were about 40% by mass. Three stuffing threads containing the conductive fibers and twelve stuffing threads not containing the conductive fibers were bundled. The proportion of conductive fibers in the entire filling yarn was 0.2% by mass. The mass of the filling thread was 3.5 g / m.
Hereinafter, conductive fibers may be labeled as antistatic yarn, 33T / 24F, and polyethylene terephthalate (PET) hollow fiber yarn, fineness 39decitex, and 12 filaments may be labeled as PET hollow fiber 39T / 12F.
Next, in the silicone resin applying step, the silicone resin was applied. In the silicone resin applying step, 15 threads for filling are bundled. In addition, 4 out of 30 yarns for stuffing using the above conductive fibers were used, and the remaining 13 yarns were stuffing yarns of Comparative Example 1 described later, that is, stuffing yarns not including conductive fibers.
As the silicone resin, an aqueous solution containing "Teron E-530" manufactured by Matsumoto Yushi Pharmaceutical Co., Ltd., 10% by mass, and "Marpoteron E-722" manufactured by the same company as a cross-linking agent, 0.5% by mass was used, and the amount to be applied was dried. By weight, 3.0 wt% was sprayed on the cotton stuffed. Next, in the heat treatment step, the silicone resin was heat-cured and fixed by heat treatment at 140 to 190 ° C. for 1 to 13 minutes.
<Creation of fabric samples for antistatic wear>
A blended spun yarn (meter count 34, single yarn use) of 65% by mass polyester and 35% by mass cotton is used as the outer and lining, and the warp yarn density is 128.5 yarns / inch, the weft yarn density is 75 yarns / inch, and the conductive yarn (conducting yarn). Three knitted yarns (trade name "Cracabo") manufactured by Claret Trading Co., Ltd. were arranged between 2 inches of warp yarns to form a woven fabric having a twill weave structure (2/1) and a mass (grain) of 165 g / m ² per unit area. This woven fabric was cut into squares with a length of 50 cm and a width of 50 cm, two sides in the width direction were sewn, and 12 quilts were placed inside in one direction. I put batting in this quilting. The total filling amount was 24.6 g. After that, both ends of the batting were sewn together with the outer material and lining. FIG. 3 is a photograph of a fabric sample of the antistatic wear product of this embodiment.
The amount of charge and charge of this fabric sample is 0.20 μC / ring (microcoolon) when the acrylic fiber woven fabric is used as a friction cloth, and 0.13 μC / ring (microcoolon) when the nylon fiber woven fabric is used as a friction cloth. rice field.

(Comparative Example 1)
Fabric samples for worn items were prepared in the same manner as in Example 1 except that conductive fibers were not used for the batting, the outer material, and the lining.

(Comparative Example 2)
A sample of the wear fabric was prepared in the same manner as in Example 1 except that no batting was used.
The above conditions and results are summarized in Tables 1 and 2.

As is clear from Table 2, it was confirmed that Example 1 was a worn item having a lower amount of charged charge and higher antistatic property (antistatic property) than those of Comparative Examples 1 and 2.
