Description

  The present invention relates to textiles and clothing.

  Conventionally, as a method of expressing unevenness on the surface of a woven fabric, a method of imparting a feeling of unevenness or unevenness to a woven fabric has been developed by using a composite spun yarn in which two or more kinds of different short fibers are mixed. For example, the knitting yarn is made into a knitting yarn by uniformly blending the undyed raw cotton or the differently dyed raw cotton with a low blending ratio of 10% by mass or less because of poor dispersibility in the mixed cotton. However, this method has a problem in that the unevenness and the color difference are not clear because the composition of different short fiber groups changes little.

  Various other studies have been made in order to solve such a problem. A mixed yarn of polyester fiber and rayon, in which the rayon with unequal length of colored rayon is 0.1 to 10% by mass, A blended yarn dispersed in the length direction has been proposed (see Patent Document 1). Separately, a composite yarn in which two types of roving yarns having different shrinkage rates are set on the same weight of a spinning machine and spun out, and the two types of fiber materials are continuously present along the yarn axis is also proposed (Patent: Reference 2.). However, in these proposals, there is a problem in that the unevenness becomes unremarkable because the composition of different short fiber groups hardly changes.

  On the other hand, as a method for obtaining fine surface irregularities, a method of using a composite spun yarn in which a mixing ratio of short fiber groups constituting the composite spun yarn is intermittently switched in the yarn longitudinal direction in the composite spun yarn constituting the woven fabric Has been proposed (Patent Document 3), fine uneven unevenness can be obtained, but the height of the unevenness is poor, and in addition, a stretchable thread for improving the ease of movement when worn as clothing. However, there is a problem in that the feeling of unevenness is further reduced by arranging.

Therefore, an object of the present invention is to provide a woven fabric and a garment having uneven and sharp surface irregularities and having excellent stretchability.

In order to solve the above problems, the present invention has the following configurations. That is,
[I] A woven fabric satisfying the following (1) and (2).
(1) A composite spun yarn in which at least two kinds of different short fibers are mixed is used for at least a part, and the mixing ratio of different short fiber groups constituting the composite spun yarn is switched in the longitudinal direction.
(2) In at least one of the warp yarn direction and the weft yarn direction, the composite spun yarns are continuously arranged in an amount of 5 to 20 and are arranged with the elastic long fibers.

  [III] The woven fabric according to [I] or [II], which has an elongation rate of at least 10% in either the warp direction or the weft direction.

  [IV] The woven fabric according to any one of [I] to [III], wherein the woven fabric has a double weave.

  [V] The woven fabric according to any one of [I] to [IV], which has a cover factor of 2000 to 3500.

  [VI] The composite spun yarn has a low crimp short fiber group having a crimp development rate of 10% or less and a high crimp short fiber group having a crimp development rate difference of 5% or more from the low crimp short fiber group. The woven fabric according to any one of [I] to [V].

  Clothing comprising at least part of the woven fabric according to any one of [VII] [I] to [VI].

  According to the present invention, it is possible to provide a woven fabric that has uneven and sharp surface irregularities and is easy to move when worn as clothing. Further, by using this as at least a part, it is possible to provide a garment having both a characteristic uneven surface and a high stretchability which have not existed in the past. Moreover, when the woven fabric of the present invention is used in a portion that comes into contact with the skin surface, it is possible to obtain cool clothing having a small contact area with the skin surface.

  Hereinafter, the present invention will be specifically described.

  The woven fabric of the present invention is a woven fabric in which at least two kinds of different short fibers are mixed and a part of the composite spun yarn is used, and the mixing ratio of different short fiber groups constituting the composite spun yarn is switched in the longitudinal direction.

  The composite spun yarn in which two or more kinds of different short fibers used in the present invention are mixed means not only the kind of fiber material but also the same fiber material having different fiber length, single fiber fineness, or cross-sectional shape or dyeing difference. Different types can be counted as one type. That is, for example, even polyester fibers, which are the same fiber material, are two types of short fibers having different shrinkage differences, and two types of single fiber fineness are 1.0 dtex and 2.0 dtex. When the fineness is different by 0.1 dtex, there may be two types, and black that is dyed with raw cotton and white that is not dyed with raw cotton can be counted as two types.

  In the woven fabric of the present invention, it is important that the mixing ratio of the staple fibers constituting the composite spun yarn is intermittently switched in the yarn longitudinal direction. Intermittently switching the mixing ratio of the short fiber groups in the longitudinal direction of the composite spun yarn means that the mixing ratio of different types of short fiber groups is switched depending on the application or purpose. It is preferable to have a portion of less than 50% by mass, and it is more preferable to have a portion in which each type of short fibers does not exist, that is, to have a portion formed of only other types of short fibers. Is. This is because the characteristics of each type of short fiber are more exerted.

  Regarding the composition of the short fiber group, a photograph of the cross section of the composite spun yarn decomposed from the woven fabric is taken with an electron microscope or a microscope, and the composition of each type of short fiber is confirmed from the photograph. In addition, a portion where a certain kind of short fiber does not exist is evaluated by the presence or absence of each short fiber from a cross-sectional photograph of the composite spun yarn or the composite spun yarn decomposed from a woven fabric.

  The composite spun yarn constituting the woven fabric of the present invention has a crimp development rate of 10% or less and a high crimp short fiber having a crimp development rate difference of 5% or more between the low crimp short fiber group and the low crimp short fiber group. It is preferable to have a group. In the composite spun yarn in which two or more kinds of different short fibers are mixed, the difference in crimp expression rate between the low crimped short fiber group and the high crimped short fiber group is 5%, not the fluctuation of the yarn length due to the arrangement of two different kinds of yarn By the above, a natural and uneven feeling of unevenness can be imparted to the woven fabric. When the difference in crimp development rate is less than 5%, the feeling of unevenness may be insufficient. The upper limit of the difference in crimp development rate is preferably 30% or less, since a suitable sense of unevenness is obtained, the floating of the yarn is appropriate, and problems such as snugging do not occur in physical properties. A more preferable range of the crimp development rate difference is 5 to 15%.

  The composite spun yarn preferably used in the present invention has a specific low crimp short fiber group and a high crimp short fiber group, and each short fiber group contains a short fiber group having a different crimp expression rate. Good. In that case, the difference in the crimp development rate between the high crimp short fiber group having the highest crimp development rate and the low crimp short fiber group having the lowest crimp development rate is defined as the crimp development rate difference.

  In addition, it is preferable that the crimp development rate of the low crimp short fiber group is 10% or less, in order to give a three-dimensional impression of unevenness. When the crimp occurrence rate of the low crimp short fiber group exceeds 10%, the crimp of each single fiber in the single fiber group in the woven fabric becomes large, so that the unevenness on the appearance becomes inconspicuous and the surface feeling without a feature is obtained. Could be. The preferred crimp development rate of the low crimp short fiber group is 3 or more and 8% or less.

  Examples of the material of the single fiber used in the low crimped short fiber group include, for example, polyester fibers such as polyethylene terephthalate fiber and cationic dyeable polyethylene terephthalate fiber, and all ordinary synthetic fibers, as well as cellulosic fibers such as acetate and regenerated fibers. Cellulosic fibers or natural fibers such as cotton, silk, and animal fibers can also be applied.

  As the cross-sectional shape of the short fibers constituting the composite spun yarn, any cross-sectional shape such as round shape, triangular shape, Y shape, cross shape, star shape, and flat shape can be used.

  As a material for the highly crimped short fibers constituting the composite spun yarn, synthetic fibers or semi-synthetic fibers having a dry heat shrinkage of preferably 10% or more are used. More preferred are highly crimped polyester short fibers, for example, polyester short fibers obtained by side-by-side or eccentric core-sheath composite of high shrinkage polyethylene terephthalate (referred to as high shrinkage PET) and low shrinkage polyethylene terephthalate (hereinafter referred to as low shrinkage PET). Is preferably used. Polyethylene terephthalate (hereinafter referred to as PET) having different shrinkage characteristics is used as a composite yarn in which side-by-side or eccentric core-sheath composite is made, and each component expresses different shrinkage, resulting in a high crimped short fiber. Is. For example, high crimp characteristics can be obtained by using PET in which a third component such as isophthalic acid is copolymerized as the high shrink PET. The degree of shrinkage property may be adjusted within a desired range by adjusting the copolymerization ratio and the copolymerization species.

  The single fiber fineness of the short fibers is preferably 0.5 to 10 dtex, more preferably 0.7 to 4 in terms of the single fiber fineness used in the composite spun yarn, from the viewpoint of satisfying both fine spinning properties and feeling. The range is 0.0 dtex. Here, when the single fiber fineness is 0.5 dtex or more, the spinning property is good. Further, when the single fiber fineness is 10 dtex or less, the texture does not become too hard, which is suitable for clothing.

  From the viewpoint of quality, the fiber length of the short fibers is preferably in the range of 25 to 200 mm, more preferably 30 to 100 mm. Here, if the fiber length is less than 25 mm, the yarn strength becomes poor, which is not preferable. Further, if the fiber length exceeds 200 mm, the spinning property is extremely deteriorated, which is not preferable.

  The yarn count of the composite spun yarn used in the present invention is preferably in the range of 10 to 100 count (cotton type), but this yarn count can be appropriately selected according to the application. For example, a woven fabric for clothing is preferably in a number of 20 to 100 (cotton type). For clothing materials such as bags, the 10th to 30th count (cotton type) is a preferred embodiment. Further, the yarn count can be changed in the longitudinal direction of the composite spun yarn according to the application, but if the yarn count is constant in the longitudinal direction of the composite spun yarn, the quality of the woven fabric will be better.

  The twist coefficient of the composite spun yarn is preferably in the range of 2.0 to 5.0, but this twist coefficient can be appropriately selected according to the application. The twisting coefficient does not have to be constant, and can be changed in the yarn longitudinal direction of the composite spun yarn according to the application.

  The composite spun yarn can be used as a slab yarn depending on the application. For example, if the slab thickness or length is less than 100% of the standard count, the yarn strength may be inferior and spun yarn may not be produced, or if it exceeds 500% of the standard count, the next step Since there is a possibility that yarn breakage may occur in the loom due to fluctuations in the count, it is a preferred embodiment that the slab thickness and length are in the range of 100 to 500% of the standard count. The slab thickness and length are more preferably in the range of 150 to 300%.

  If the slab length is less than 30 mm, the slab cannot be formed because it is shorter than the single fiber length, and if it is more than 2000 mm, the slab is not emphasized when the fabric is used. Is preferably in the range of 30 to 2000 mm. The slab length is more preferably in the range of 50 to 1000 mm.

  The composite spun yarn can be processed not only into a single yarn but also into a twisted yarn such as a twin yarn and a triple yarn, or a composite process with a long fiber.

  In the woven fabric of the present invention, it is important that the composite spun yarns are continuously arranged in an amount of 5 to 20 in at least one of the warp direction and / or the weft direction and are arranged with the elastic long fibers. .. The stretchable long fiber is not particularly limited as long as it is a long fiber having stretchability, but it is a polyurethane fiber, a polyether / ester fiber, or a side-by-side (bonding type) or an eccentric sheath type of these fibers. , Or PET and polytrimethylene terephthalate (hereinafter referred to as PTT), PET and polybutylene terephthalate (hereinafter referred to as PBT), side-by-side or eccentric core-sheath type conjugate yarn, and the like. These elastic long fibers are preferably in the form of multifilaments, and are also preferably used as twin yarns.

  Here, "the composite spun yarn is continuously arranged in an amount of 5 to 20 and is arranged with elastic long fibers" means that the yarn is continuously arranged in an amount of 5 to 20 and then the elastic long fibers are arranged. Means that. An embodiment in which this arrangement is repeated is shown. In the case of multiple weaving, for example, a composite spun yarn may be arranged on the front side and one stretchable long fiber may be arranged as a back yarn for every 5 to 20 yarns.

  Arranging 5 to 20 continuous composite spun yarns is preferable because an uneven surface with unevenness can be formed. A more preferable range is 7 to 15. It is possible to adjust the height of the surface unevenness by the number of arrangements of the composite spun yarn and elastic long fibers, and by varying the number of arrangements in the woven fabric, uneven and sharp uneven surface and stretchability can be obtained. Can be given. Further, if the continuous arrangement of the composite spun yarn is less than 5, the unevenness may be divided and the size of the unevenness may be insufficient. Further, if the number is larger than 20, the irregularities become coarse and problems may occur in physical properties such as snugging.

  Further, in the woven fabric of the present invention, it is preferable that the arithmetic mean height Sa of at least one surface is 60 to 300 μm, because a sharp and uneven surface feeling can be obtained. If Sa is less than 60 μm, the woven fabric may have a poor texture, and if Sa is more than 300 μm, physical properties such as snacking may be deteriorated. The more preferable range of Sa is 100 to 200 μm.

  The woven fabric of the present invention preferably has an elongation rate of at least 10% in either the warp direction or the weft direction from the viewpoint of ease of movement when worn as clothing. The warp direction here is a direction parallel to the warp yarn, and the weft direction is a direction parallel to the weft yarn. The elongation rate of 15% or more is more preferable because the ease of movement is further improved. The upper limit is preferably 30% or less from the viewpoint of reducing the feeling of elasticity.

  Further, the woven fabric of the present invention is not limited to any woven fabric structure, but is preferably a double woven fabric from the viewpoint of expressing stretchability, and is a double woven fabric in which the elastic long fibers are arranged as a back yarn. It is more preferable that the surface exposure of the elastic long fibers can be suppressed and more uneven surface unevenness can be obtained. In this case, the stretchable long fibers may be arranged as a back yarn every time 5 to 20 continuous spun composite yarns are arranged.

  The woven fabric of the present invention preferably has a cover factor of 2000 to 3500 from the viewpoint of surface irregularities, and more preferably 2200 to 3000. If the cover factor is less than 2000, the binding force between the threads will be weakened and the stress will be dispersed, resulting in less unevenness. If the cover factor is greater than 3500, the binding force between the threads will be too strong and the fabric shrinkage will be hindered. The unevenness may be poor.

The cover factor here is expressed by the following equation.
Cover factor = N1 x (D1) ^1/2 + N2 x (D2) ^1/2
(In the formula, N1 represents the warp density (pieces / 2.54 cm), N2 represents the weft density (pieces / 2.54 cm), D1 represents the warp yarn fineness (dtex), and D2 represents the weft yarn fineness (dtex). In the case of a multi-layer structure, the number of yarns in all layers is used as the density. For example, when using yarns having different finenesses, the respective finenesses and densities are used for calculation. The cover factor N1 × (D1) ^1/2 of the warp when the warp density n2 of the warp having the fineness d2 is calculated as n1 × (d1) ^1/2 + n2 × (d2) ^1/2 .)

  The thus-obtained woven fabric of the present invention can be used as a garment that has both a characteristic uneven surface and a high stretchability, which are not present in ordinary wear. Further, when the woven fabric of the present invention is used in a portion that comes into contact with the skin surface, it can be preferably used for clothing such as bottoms and jackets for summer because it has a small contact area with the skin surface and is cool clothing.

  Hereinafter, the present invention will be described with reference to examples, but the present invention is not necessarily limited to these.
