Description

  The present invention relates to a woven fabric, and more particularly to a woven fabric capable of improving design properties.

  In general, a woven fabric used for clothes is a plain weave in which wefts are woven into warps. When single yarn is used as the warp, Z twist yarn is used, and when twist yarn is used, S twist yarn is used. Further, when a single yarn is used as the weft, a Z twist yarn is used, and when a double yarn is used, an S twist yarn is used. In these plain woven fabrics, a pattern based on the type of yarn on the surface of the fabric, that is, the difference between S-twisted yarn and Z-twisted yarn, was not plain.

On the other hand, in some cloth products such as furoshiki, the following ingenuity has been made to enhance the design of the surface. That is, a warp woven fabric in which one or a plurality of S strong twist yarns and Z strong twist yarns are alternately woven as wefts with respect to the warp has been proposed. This textured fabric has a texture that is deep, sharp, and directional. (For example, see Patent Documents 1 and 2)
JP-A 63-264944 Japanese Patent Laid-Open No. 01-61535

  However, in the former fabric, a pattern of two or more colors based on the type of yarn, that is, the difference between the S twisted yarn and the Z twisted yarn was not formed. Therefore, for example, when it is desired to form a striped pattern on the surface of the woven fabric, after forming the woven fabric, a method of forming a pattern such as a striped pattern with a dye, and at least one of warp or weft is colored with a dye, Means for weaving a woven fabric such as a stripe pattern using the colored warp or weft has been employed.

  On the other hand, the latter warp woven fabric weaves one or a plurality of Z strong twist yarns or a plurality of Z strong twist yarns as wefts, but the entire surface is uniform and only exhibits a simple warp pattern, for example, a stripe pattern is formed. I couldn't.

  An object of the present invention is to provide a woven fabric in which a pattern can be observed by weaving S twisted yarn and Z twisted yarn as a group of at least one of warp and / or weft.

In order to solve the above problems, the invention according to claim 1 is a woven fabric composed of warps and wefts, wherein the warps and / or wefts are composed of an S twist group consisting of a plurality of S twist yarns and a plurality of Z twist yarns. Weaving so that one set of Z twist yarn groups appear, or both groups appear alternately one by one, and at least one of the S twist yarn of the S twist yarn group or the Z twist yarn of the Z twist yarn group is a bright yarn , The gist is that an S / Z twisted yarn group in which S twisted yarn and Z twisted yarn are mixed is woven into a boundary portion between the S twisted yarn group and the Z twisted yarn group .

The invention described in 請 Motomeko 2 Oite to claim 1, wherein the one bright yarn Z twisting of S twist yarn or Z twist yarn group S twisting group, and summarized in that and the other was dull yarn.

The gist of the invention described in claim 3 is that, in claim 1 or 2 , the S twist yarn of the S twist yarn group and / or the Z twist yarn of the Z twist yarn group is made into a single yarn.

According to the invention according to any one of claims 1 to 3 , the warp and / or the weft are set such that a plurality of S twist yarn groups and a plurality of Z twist yarn groups are represented as one set, or both groups are set as one set. The yarns were woven so as to appear alternately, and at least one of the S-twisted yarn group or the Z-twisted yarn group was a bright yarn. For this reason, for example, when light is applied to the woven fabric from the front side and the woven fabric is observed from the front side, the light reflection amount of the S twisted yarn group or the Z twisted yarn group is the same and is observed as a plain pattern. The However, when light is applied to the fabric, for example, from the front side and the fabric is observed obliquely from above, the amount of light reflected by the S twist yarn of the S twist yarn group and the Z twist yarn of the Z twist yarn group is different due to the difference in twist direction. Since they are different, a difference in brightness occurs between the S twisted yarn group and the Z twisted yarn group, and patterns having different brightness differences can be observed in at least two places, and the design can be improved. Since the amount of reflection of the light applied to the fabric changes depending on the position of the light source with respect to the fabric and the position of the viewpoint for observing the fabric, the brightness difference also changes and the pattern also changes. Further, since the S / Z twisted yarn group in which the S twisted yarn and the Z twisted yarn are mixed is woven into the boundary portion between the S twisted yarn group and the Z twisted yarn group, the intermediate brightness between the patterns having different brightness differences appearing in at least two places described above. The pattern of the difference can be observed, and the design of the pattern can be further improved.

In the invention according to claim 2 , since one of the S twisted yarn of the S twisted yarn group or the Z twisted yarn of the Z twisted yarn group is a bright yarn and the other is a dull yarn of low brightness, the S twisted yarn group or the Z twisted yarn comprising the bright yarn is used. When the light reflection amount of the group is large and high brightness is observed, the light reflection amount of the Z twist group or the S twist group using the low lightness dull yarn is low, and the lightness is at least in two places. The pattern due to the difference can be observed. In addition, when the light reflection amount of the S twist yarn group or the Z twist yarn group made of bright yarn is small and is observed at low brightness, the light reflection of the Z twist yarn group or S twist yarn group using the low lightness dull yarn is used. Since the amount is also low in brightness, the entire fabric becomes low in brightness and almost no pattern can be observed.

In the invention of claim 3 , since the S twisted yarn of the S twisted yarn group and / or the Z twisted yarn of the Z twisted yarn group is made into a single yarn, the surface of the S twisted yarn group and the Z twisted yarn group as compared with the yarn of two or more yarns The difference in the amount of reflected light increases, and the brightness difference of the pattern can be increased. That is, since the S twist single yarns and Z-twisted single yarn numerous fibers are twisted in the S twist direction and the Z twist direction at the same twisting angle, lightness becomes monotonous incident direction of light reflection on the single yarn surface The difference appears strongly. However, for example, in the case of two-ply yarns are taken and twist angle of the single yarn fibers constituting it, to twist angles of the two single yarns mutually different incident direction of light reflection on the two-ply yarns surface complex The brightness difference appears weak. For this reason, the woven fabric using a single yarn can increase the brightness difference of a pattern compared with the woven fabric using a double yarn.

Hereinafter, an embodiment in which the present invention is embodied in a woven fabric capable of observing a stripe pattern will be described with reference to FIGS.
As shown in FIG. 1, the woven fabric 11 is woven into a plain weave by warp yarns 12 made of a number of bright yarns and weft yarns 13 made of a number of bright yarns.

  The weft 13 is composed of an S twisted yarn group 14S formed by eight S twisted yarns 14 to 14 continuously woven and eight Z twisted yarns 15 to 15 continuously woven next to the S twisted yarn group 14S. The Z twisted yarn group 15Z thus formed is woven repeatedly and alternately one by one.

The warp yarns 12 are all spun single yarns, and Z twist yarns 15 to 15 are used in this embodiment. The S twist yarn 14 and the Z twist yarn 15 are all spun single yarns.
The bright yarn described above is a glossy yarn, and in this embodiment, a spun yarn of polyester or a spun yarn of cotton imparted with gloss by mercerization processing is used. Rayon or bright modacrylic fiber may be used. Furthermore, it may be a super-long cotton thread or silk thread, or may be a thread in which a glossy filament is spirally covered on the core thread.

Next, the operation of the fabric 11 configured as described above will be described.
As shown in FIG. 2, when light is applied to the surface of the fabric 11 in the direction of the arrow by the parallel light source 21, the amount of reflection of light applied to the S twisted yarn 14 and the Z twisted yarn 15 is as shown in FIG. Since they are different as shown in (b), the reflection amounts of light reflected by the S twist group 14S and the Z twist group 15Z are also different. 3A and 3B, a large number of fibers 14a and 15a forming the S twisted yarn 14 and the Z twisted yarn 15 are actually used, but are limited to a few for convenience of explanation. As apparent from FIG. 3 (a), in the S twisted yarn 14, the amount of light reflected by each fiber 14a so as to be folded back toward the light source 21 increases, and the amount of light incident on the observer's viewpoint 22 is increased. Decreases and is observed dark. On the contrary, the Z twisted yarn 15 is irradiated with light substantially parallel to the valleys 15b of the fibers 15a and 15a, so that the amount of light reflected so as to be folded back toward the light source 21 is reduced, and the observer's viewpoint 22 The amount of light incident on is increased and brightly observed. Therefore, as shown in FIG. 1, when the light source 21 is diagonally upward to the right and the viewpoint 22 of the observer of the fabric 11 is on the left side, the S twist group 14S forming the weft 13 is observed darkly, and the Z twist group 15Z is observed brightly. For this reason, a lightness difference arises in the light observed by S twist group 14S and Z twist group 15Z, and a striped pattern can be observed. Further, since all the warp yarns 12 are formed of the Z-twisted yarns 15, they are observed as low-lightness colors with a small amount of reflection as shown in FIG.

  As described above, even if the warp yarn 12 and the weft yarn 13 are made of the same material and have the same color, the lightness difference due to the difference in the amount of reflected light between the S twist yarn group 14S and the Z twist yarn group 15Z. Thus, a striped pattern can be observed on the fabric 11. The amount of light reflected from the parallel light source 21 applied to the fabric 11 toward the light source 21 is constant when the fabric 11 and the parallel light source 21 are held at predetermined positions. However, when the position of the viewpoint 22 for observing the fabric 11 changes, the difference in lightness of the observed light also changes, and the striped pattern also changes.

  In FIG. 1, since the woven fabric 11 is limited to a small area, a striped pattern can be observed as a whole. However, when the woven fabric 11 has a large area, there is a portion that is observed as no pattern. The striped pattern will be observed locally.

In the embodiment, since both the S twisted yarn 14 and the Z twisted yarn 15 are single yarns, the light radiated from the parallel light source 21 to the parallel light source 21 side of the light emitted from the parallel light source 21 is compared with a yarn that is more likely to be irregularly reflected than twin yarns. The amount of reflection increases, and the brightness difference of the striped pattern can be increased. That is, in the S twisted yarn 14 and the Z twisted yarn 15, since a large number of fibers are twisted in the S twist direction and the Z twist direction at the same twist angle, the light incident / reflection direction on the surface of the single yarn is monotonous and there is a difference in brightness. It appears strongly. However, for example, in the case of two-ply yarns are taken and twist angle of the single yarn fibers constituting it, to twist angles of the two single yarns mutually different incident direction of light reflection on the two-ply yarns surface complex The brightness difference appears weak. For this reason, the woven fabric using a single yarn can increase the brightness difference of a pattern compared with the woven fabric using a double yarn.

As a double yarn, two S-twisted yarn groups, each consisting of two S-twisted single yarns as S-twisted double yarns, and a woven fabric that combines two Z-twisted single yarns as Z-twisted double yarn groups, and two Z-twisted yarn groups, the S-twist and S-twist ply yarn group a single yarn is S twist ply yarn, Z twist fabrics that combine ply yarn group of S twist single yarns two is a Z twist ply yarn, the result of the experiment to observe a pattern I was able to. However, a Z twist ply yarn group of S twist single yarns double this is a Z twist ply yarn, fabric two of Z twist single yarns that combine S twist ply yarn group was S-twisted two-ply yarns are pattern scarcely observed Was not. This is presumably because the light incident / reflecting direction on the surface of the twin yarn and the light incident / reflecting direction on the surfaces of the two single yarns constituting the twin yarn are different from each other and cancel each other.

  In the said embodiment, since the number of each of the S twisted yarn 14 of the S twisted yarn group 14S and the Z twisted yarn 15 of the Z twisted yarn group 15Z was eight, the striped pattern observed in comparison with the eight twisted yarn groups or less The width can be widened to make a conspicuous striped pattern, and the design can be improved.

In addition, you may change the said embodiment as follows.
As shown in FIG. 4, as the warp 12, the S twist group 14S and the Z twist group 15Z may be alternately and repeatedly arranged one by one. In this case, the surface pattern of the fabric 11 is observed as a checkered pattern.

  As shown in FIG. 5, for example, a white (first color) yarn is used for both the S twisted yarn group 14S composed of 20 S twisted yarns 14 and the Z twisted yarn group 15Z composed of 20 Z twisted yarns 15, for example. For example, a yellow (second color) yarn may be used for both the 20 S twist yarn groups 14S and the Z twist yarn group 15Z of the 20 Z twist yarns 15 connected to the Z twist yarn group 15Z. In this case, since the shades of white (first color) and shades of yellow (second color) appear alternately, a total of four types of striped patterns can be observed, and the design is further improved. Can do. The first and second colors may be various color combinations such as white vs. green, yellow vs. orange, and white vs. gray.

  As shown in FIG. 6, for example, 5 to 10 S twist yarns 14 and Z twist yarns 15 are alternately woven into the boundary portion between the S twist yarn group 14S and the Z twist yarn group 15Z, and the S / Z twist yarn group 145SZ is obtained. It may be formed. Alternatively, two, three, or four may be interwoven. In these cases, the amount of reflection of the light at the boundary portion toward the parallel light source 21 is an intermediate amount between the same amount of light reflected by the S twist yarn group 14S and the same amount of light reflected by the Z twist yarn group 15Z (intermediate amount Brightness), a three-stage striped pattern can be observed. Furthermore, the S • Z twisted yarn group 145SZ is, for example, Z • S • S • Z • S • Z • Z • S, or Z • S • S • S • Z • S • S • Z • S • Z •. S, Z, Z, S, Z, Z, Z, S, or any other combination may be used. In these cases, the intermediate brightness of the S / Z twisted yarn group 145SZ can be changed gently.

The configuration of the S / Z twisted yarn group 145SZ is applied to all other woven fabrics described in the section of this embodiment.
As shown in FIG. 7A, the S twist yarn group 14S of the weft may be a bright yarn, and the Z twist yarn group 15Z may be a dull yarn or a semi-dal yarn. As the dull yarn used in this embodiment, for example, there is a spun yarn of a halogen-containing fiber containing 5 to 60% by weight of a flame retardant mainly composed of antimony oxide. The halogen-containing fiber is a copolymer comprising 40 to 70% by weight of acrylonitrile, 60 to 30% by weight of a halogen-containing monomer such as vinyl chloride or vinylidene chloride and 0 to 3% by weight of a monomer containing a sulfonic acid group. It consists of

  In this other example, the striped pattern changes according to the change in the reflection amount of the S twist group 14S of the bright yarn. For this reason, for example, as shown in FIG. 7 (a), when the light source 21 is obliquely left upward and the fabric 11 is viewed from the front, the amount of reflection of the light of the S twisted yarn group 14S toward the parallel light source 21 is reduced. Light entering the viewpoint 22 has high brightness, and a striped pattern is observed. On the contrary, as shown in FIG. 7B, when the light source 21 is obliquely upward to the right and when viewed from the front, the amount of reflection of the light of the S twist group 14S toward the parallel light source 21 increases and enters the viewpoint 22. The light becomes low in brightness and almost no striped pattern is observed.

  In the other example, the S twist group 14S of the weft 13 may be a dull thread or a semi-dull thread, and the Z twist group 15Z may be a bright thread. Although not shown, the warp yarn 12 may be composed of an S twist yarn group 14S and a Z twist yarn group 15Z, the S twist yarn group 14S may be a dull yarn or a semi-dull yarn, and the Z twist yarn group 15Z may be a bright yarn. Further, the S twist yarn group 14S of the warp yarn 12 may be a bright yarn, and the Z twist yarn group 15Z may be a dull yarn or a semi-dull yarn.

  As shown in FIG. 8A, a set of S twist yarn group 14S and Z twist yarn group 15Z may appear only on weft yarn 13. As shown in FIG. 8B, a set of S twist group 14S and Z twist group 15Z may appear only on the warp 12. As shown in FIG. 8 (c), one set of S twist yarn group 14S and Z twist yarn group 15Z may appear on the weft yarn 13 and the warp yarn 12. In this case, since the brightness difference changes in three stages, three types of patterns can be observed. As shown in FIG. 8 (d), only two sets of S twist yarn groups 14S and Z twist yarn groups 15Z may appear alternately on the weft yarns 13, or three or more pairs may appear alternately. As shown in FIG. 8 (e), only two sets of S twisted yarn groups 14S and Z twisted yarn groups 15Z may alternately appear on warp 12, or three or more pairs may appear alternately. As shown in FIG. 8 (f), the warp yarn 12 and the weft yarn 13 may have two pairs of S twist yarn groups 14S and Z twist yarn groups 15Z, or three or more pairs, although not shown. Further, although not shown, the number of folding groups of both the S twist group 14S and the Z twist group 15Z used for the warp 12 and the weft 13 is set such that the warp 12 is an arbitrary number from 3 to 50, for example, the weft 13 However, it can be set to an arbitrary number from 3 to 50 sets.

  As the combination of single yarn and double yarn of the S twist yarn group 14S and the Z twist yarn group 15Z of the warp yarn 12 and the weft yarn 13, for example, patterns 1 to 16 are conceivable as shown in FIG. In FIG. 9, “single” may be “sweet twisted yarn”, and “−” may be “ordinary twisted yarn”. In FIG. 9, “single” may be “strong twisted yarn” and “−” may be “ordinary twisted yarn”. Furthermore, in FIG. 9, “single” may be “bright yarn” and “−” may be “dull yarn or semi-dull yarn”.

  ○ Although not shown, a color yarn group made of colored yarns such as gray, red, yellow or blue, which is different from the colors of the S twist yarn group 14S and the Z twist yarn group 15Z, is interwoven between the S twist yarn group 14S and the Z twist yarn group 15Z. It may be. One or more covering yarns may be woven between the S twist group 14S and the Z twist group 15Z.

Although not shown, the thickness (count) and driving density of each of the S twisted yarn group 14S and the Z twisted yarn group 15Z may be changed.
The warp yarn 12 and / or the weft yarn 13 are woven so that at least one set of S twist yarn group 14S and Z twist yarn group 15Z, or both groups appear alternately, and the S twist yarn 14 or Z of the S twist yarn group 14S. At least one of the Z twisted yarns 15 of the twisted yarn group 15Z may be a bright yarn, and the other twisted yarn may be a dull yarn or a semidull yarn. In these cases, when light is applied to the woven fabric, for example, from the light source, the viewpoint of the light is reflected on the light source side of the S twisted yarn 14 of the S twisted yarn group 14S and the Z twisted yarn 15 of the Z twisted yarn group 15Z. Thus, a lightness difference is generated in the light of the S twist yarn group 14S and the Z twist yarn group 15Z that are observed by 22 so that patterns with different lightness differences can be observed at least at two locations, and the design can be improved.

In each of the above embodiments, the S twist group 14S and the Z twist group 15Z of the warp 12 and / or the weft 13 may be three or more twins.
In each of the above embodiments, the number of yarns of the S twist group 14S and the Z twist group 15Z may be 2, 3, 4, 5, 6, or 7 or more, respectively. The number of the S twist group 14S and the Z twist group 15Z may be 8 or more. Furthermore, the number of yarns in both yarn groups may be 10, 15, 20, 25, or 30 or more, respectively, and in these cases, 9, 14, 19, 24, or 29 As compared with the following number of twisted yarn groups, the width of the stripe pattern is further widened, and a noticeable stripe pattern can be observed.

  (Definition) In this specification, the woven fabric includes a fabric manufactured by a weft insertion warp knitting machine. Further, the S twisted yarn or the Z twisted yarn includes, in addition to a single yarn, a twin yarn, and a triplet twisted yarn that are given a twist, a yarn in which a filament is covered in an S twisted spiral shape or a Z twisted spiral shape.
