  The present invention relates to a garment comprising a bag-woven fabric using stretch yarns as warp yarns and weft yarns. More particularly, the present invention relates to a garment made of a woven fabric in which a filling is filled between a front fabric and a back fabric of a woven fabric using stretch yarns for warp and weft, in particular to a down jacket.

  Down jackets, down vests, clothing provided with synthetic fibers that are artificial feathers, such as ski wear, are quilted to eliminate the movement of the feathers and the like that are filled between the front side fabric and the back side fabric. However, in the quilting, there is a sewing perforation in the cloth, so there is a problem that warm air accumulated inside the back cloth escapes to the outside through the perforation when worn. There is also a problem that fillings such as feathers and artificial feathers are blown out from perforations (also referred to as down holes). Furthermore, in the case of the fabric subjected to quilting, there is also a problem that rainwater easily infiltrates from the sewing hole.

  In order to solve these problems, Patent Document 1 below comprises a front side cloth, a back side cloth, and a filler to be filled between the front side cloth and the back side cloth, and the front side cloth and the back side cloth are woven. A garment comprising a double fabric formed by In the clothing composed of such multiple fabrics, there is no perforation, so the air inside the clothing is difficult to escape to the outside, it is excellent in cold protection, and it is hard to invade outside air, it is excellent in waterproofness, and the texture is more excellent by the filling Is supposed to be equipped.

However, in the down jacket disclosed in Patent Document 1, although there are few down omissions and high water pressure resistance, there is little stretchability (stretchability) of the base fabric of the double fabric itself, and there is a sense of pinching when worn (wear As a result, the warm air inside the clothes escapes to the outside due to wearing and the cold resistance is lowered.
Further, in the double fabric disclosed in Patent Document 1, since the air permeability of the base fabric is low, i.e., 1 ml / cm ² / sec or less, heat is stagnant when worn and it is difficult to adjust the temperature inside the garment.
Furthermore, in the double woven fabric disclosed in Patent Document 1, the bonding location of the woven fabric is a double woven structure, and since the double woven structure is provided with a bonding point, density unevenness of the weft occurs. The appearance quality of the front side fabric is deteriorated.

Hereinafter, embodiments of the present invention will be described in detail.
<Definition of terms>
In the present specification, the term "clothing" specifically refers to clothes such as down wear, down jackets, down coats, etc., but is not limited to these clothes, and bedding, etc. for kneeling, futons, sleeping bags, etc. Intended to be included.
Also, in the present specification, "down" is intended to encompass an artificial feather material that is not limited to natural feathers, and is composed of synthetic fibers that mimic the characteristics of natural feathers.
Further, in the present specification, the term "garment made of a woven fabric" is intended to encompass one that uses a woven fabric as a part of the clothing.

  Hereinafter, in order to deepen the understanding of the present embodiment, a double woven fabric having a conventional sewn portion and a woven fabric of the present embodiment will be described in order.

<Double weave with conventional sewn parts>
A general multiple woven fabric, for example, a double woven fabric 20, is manufactured by sewing using a binding yarn 23 in a state where two single unit fabric 21 and 22 are superposed on the front and back, as shown in FIG. Ru. The binding yarns 23 can be cotton or synthetic yarns. Such a double fabric 20 is used as a material of, for example, clothing such as a belt, a coat, a jacket, slacks, and a bag.
For example, in order to manufacture a belt using the double fabric 20, as shown in FIG. 6, after cutting the double fabric 20 as a material into a predetermined shape, as shown in FIG. The binding yarns 23 present on the periphery of 20 are cut with a scissors or a knife while opening the peripheries of the unit fabrics 21 and 22 to remove cut yarn waste. Next, as shown in FIG. 8, the edges of the unit fabrics 21 and 22 are folded back inward and pressed with an iron to form an ear 24, and the folded-back portion is sewn with a sewing thread 25 as the ear 24.

  However, in the double woven fabric 20 shown in FIG. 5, the binding yarn 23 which is a twisted yarn is sewn into the unit woven fabrics 21 and 22 with a considerable tension, and the air layer in the overlapping portion of the unit woven fabrics 21 and 22 becomes small. Therefore, it does not become excellent in heat retention and bulkiness. If filling materials such as feathers are filled between the unit fabrics 21 and 22, it becomes excellent in heat retention and bulkiness, but as described above, while opening the peripheries of the unit fabrics 21 and 22, scissors or a knife etc. Cutting off the thread waste, folding the peripheral portions inward and pressing with an iron to make the ear 24 and sewing the portion folded back as the ear 24 with the sewing thread 25 is required. Moreover, since there is a through-hole in which these yarns penetrate the unit woven fabrics 21 and 22 at the location of the binding yarn 23 and the sewing yarn 25, fillings such as feathers easily come out of the through-hole, and are accumulated inside the clothes by wearing. Warm air is likely to leak out.

<Organization of bag woven fabric>
As the weave structure of the double part of the bag woven fabric having the front side fabric and the back side fabric constituting the clothes of the present embodiment, a plain weave “is a weave in which warps and wefts are regularly tolerated alternately”, “warp And wefts do not cross each other alternately, there is a weave of 1x2 to which one thread is to be dropped next when tolerance is 1 or 2 such as 1x3 to which it is further dropped by tolerance. It is a weave with a lot of floats and it looks like only the warp is exposed on the surface. ”Yarn,“ based on other weaves such as plain weave and satin weave, and the color yarn you want to make on the background "Weave how to put on" solid weave, "Weave way that is most suitable to express fine pattern and character, or use special yarn, and fine pattern which can not express in usual weave manner by raising thread density Is a weave that can reproduce characters and letters. "High-density weave," Strong and strong against distortion. Examples of such materials include non-shrinkage that is a weave method, and a satin weave that has a non-glossy expression weave as a rough surface like a pear surface. Among these weaves, a plain weave which is thin but strong as a cloth is preferred as the weave structure of the double part of the bag-woven fabric, since the yarn crosses are more in comparison with other weaves.

FIG. 1 shows a cross-sectional view of an example of the woven fabric.
In FIG. 1, reference numeral 1 denotes a warp, reference numeral 2 denotes a weft, reference numeral 3 denotes a front side cloth, and reference numeral 4 denotes a back side cloth. Further, the upper part of FIG. 2 is a tissue diagram of the woven structure of part A of FIG. 1, and the lower part of FIG. 2 is a tissue diagram of the woven structure of part B of FIG. The middle row in FIG. 2 shows the junction of the front side fabric and the back side fabric, and in the organization diagram of FIG. 2, the second, sixth, and tenth squares from the left, and the fourth and eighth squares from the left There are bonding points in the double weave structure at a total of six places, the eighth square from the lower side in each of the twelfth square.

  There are no particular limitations on the bonding site in the woven fabric of the present embodiment, but no double-woven fabric has a bonding point, and it is preferable that the single-texture bonding site be a 3: 1 plain weave. This is because this eliminates the occurrence of streaks in the front side fabric and improves the appearance quality of the front side fabric. FIG. 3 shows a tissue diagram in the case where the tissue at the single-woven-texture-bonded portion is a 3: 1 plain weave.

<Stretch yarn>
The warps and wefts constituting the front side fabric and the back side fabric in the woven fabric of the present embodiment are not particularly limited as long as they are stretchable (stretchable) yarns, and may be monofilament yarns or multifilament yarns. It is preferable that it is nylon FTY (Filament Twisted Yarn) which covered the long fiber centering on polyurethane elastic yarn from a viewpoint of the intensity | strength, abrasion resistance, etc. of the cloth | dough when using for clothing. As nylon FTY, NyFTY (Pu17TxNyw33T) is illustrated. The fineness of the stretch yarn is preferably 10 dtex or more and 90 dtex or less in order to secure the strength of the fabric and to provide a lightweight thin fabric.

  The breaking strength of the stretch yarn is preferably 3.5 cN / dtex or more, more preferably 4.5 cN / dtex or more, preferably 10 cN / dtex or less, and 6 cN / dtex or less More preferable. When the breaking strength of the stretch yarn is in the above range, a fabric having a suitable tear strength as a garment can be obtained.

  The breaking elongation of the stretch yarn is preferably 35% or more, and preferably 50% or less. If the breaking elongation is less than 35%, there is a risk of tearing when a given force is applied to the front side fabric or the back side fabric, while if the breaking elongation exceeds 50%, the friction with the weaving device may occur. Strong tension resulting from it makes it easy to break.

  When the stretch yarn is a multifilament, the single yarn fineness is preferably 0.5 dtex or more, more preferably 1.0 dtex or more, and preferably 3.0 dtex or less, and 2.5 dtex or less. It is more preferable that When the single yarn fineness is in the above range, it has an appropriate tear strength.

  The material of the stretch yarn can be composed of various synthetic fibers such as nylon fiber and polyester fiber, except for polyurethane elastic yarn in the case of FTY in which long fibers are covered around polyurethane elastic yarn as an axis. Although polyester fibers are preferred from the viewpoint of strength, dimensional stability, etc., nylon fibers are preferred from the viewpoint of abrasion resistance and strength. As polyester fiber, the fiber which consists of a polyethylene terephthalate, a polybutylene terephthalate, etc. can be mentioned, for example. It may be a fiber made of a copolymerized polyester obtained by copolymerizing an aliphatic dicarboxylic acid such as isophthalic acid, 5-sodium sulfoisophthalic acid or adipic acid as an acid component with polyethylene terephthalate or polybutylene terephthalate. The combination of fibers constituting the multifilament by the fibers may be the same or different, and may be appropriately combined.

The obtained green fabric was finished by finish-widthing to finish a bag-woven fabric. The spacing 6 between the bonding points of the finished woven woven fabric was 4.9 cm. The results of measurement of yarn use, CF, structure, flexural rigidity and air permeability of the obtained woven fabric are shown in Table 1 below.

  The down jacket 5 shown in FIG. 4 was produced using the finished woven fabric and using Air Flake (registered trademark) (60 bundles) manufactured by Kurashiki Spinning Co., Ltd. as a filling. The fabric was arranged so that the vertical direction of the fabric was in the vertical direction of the jacket. The measurement results of the applied pressure of the down jacket, the elongation rate, the temperature / humidity change in the clothes, and the weight of the down drop obtained are shown in Table 2 below.

Comparative Example 1
Using NyFTY (pu17TxNyw33T) as a warp and a warp, an air jet room weaves a single-layered plain weave fabric with a warp density of 150 yarns / inch (2.54 cm) and a weft yarn density of 110 yarns / inch (2.54 cm). The obtained green fabric was finished by finishing, and a single layer plain weave fabric was finished. The finished single-layer plain-woven fabric is sewn using polyester filament plied yarn which is an industrial sewing thread as a binding yarn, and a double plain-woven fabric having bonding locations substantially the same as the bag-woven fabric of Example 1 I got The fabric was arranged so that the vertical direction of the fabric was in the vertical direction of the jacket, and sewing was performed in the form of a bag along the lateral direction of the fabric. The results of measurement of the yarn use, CF, texture, flexural rigidity and air permeability of the resulting double plain weave fabric are shown in Table 1 below.

  After finishing, using the double plain weave fabric after sewing and using Air Flake (registered trademark) (60 bundles) manufactured by Kurashiki Spinning Co., Ltd. as a filling, down jacket as in Example 1 Was produced. The measurement results of the applied pressure of the down jacket, the elongation rate, the temperature / humidity change in the clothes, and the weight of the down drop obtained are shown in Table 2 below.

Comparative Example 2
It is a completely double flat weave structure with a warp density of 426 yarns / inch (2.54 cm) and weft yarn density of 389 yarns / inch (2.54 cm) by the water jet room using Ny22T as non-stretch yarns for warp and warp yarns, The binding points were woven in the double weave with the binding points shown in FIG. The obtained green fabric was finished by finish-widthing to finish a bag-woven fabric. The spacing of the bonding points of the finished woven woven fabric was substantially the same as in Example 1. The results of measurement of yarn use, CF, structure, flexural rigidity and air permeability of the obtained woven fabric are shown in Table 1 below.

  The down jacket 5 was produced in the same manner as in Example 1 using the finished woven fabric and using Air Flake (registered trademark) (60 bundles) manufactured by Kurashiki Spinning Co., Ltd. as a filling. The fabric was arranged so that the vertical direction of the fabric was in the vertical direction of the jacket. The measurement results of the applied pressure of the down jacket, the elongation rate, the temperature / humidity change in the clothes, and the weight of the down drop obtained are shown in Table 2 below.

  As shown in Table 2, the down jacket of Example 1 has a lower applied pressure and a higher elongation rate than the down jacket of Comparative Example 2, so there is no feeling of pinching, so it is comfortable to wear and worn. -There was almost no heat retention at the time of operation, and the temperature and humidity in the clothes could be kept comfortable. Moreover, since the down jacket of Example 1 does not have a sewn portion at a joint location, there is no puckering that can be done at the time of sewing, and compared with the down jacket of Comparative Example 1, particularly, the fabric vertical direction ( The extension performance at the time of elbow bending operation was excellent. On the other hand, in the down jacket of the comparative example, it can not follow the amount of extension of the human body, and the fabric is misaligned, which is understood to be the cause of the feeling of pinching. In addition, since the binding site of the bag woven fabric of the down jacket of the example is a single-woven 3: 1 plain weave structure, there are no density spots of weft on the front side fabric compared to the down jacket of Comparative Example 2, and the appearance quality is improved. It was good.
