BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretchable woven and knitted fabric having a novel color effect and a method for producing the stretchable woven and knitted fabric.
TECHNICAL FIELD The present invention relates to a stretchable woven or knitted fabric having a moving and fascinating color effect in which a bead effect is changed by stretching when worn, and a method for producing the stretchable woven or knitted fabric.

[0002]

2. Description of the Related Art Heretofore, a woven or knitted fabric having a surface layer composed of two or more kinds of threads colored in different colors has been known mainly for producing a pattern effect. It is difficult to produce a moving color effect because two or more types of different yarns only form the surface layer in a plane or with some unevenness.

As another example, for example, in a warp knitted fabric of two sheets, yarns of different colors are arranged on the front side and the rear side to set an appropriate structure and yarn density. Although a knitted fabric having an iridescent effect can be obtained, such a fabric does not have elasticity, and a moving color effect produced by a change in yarn density due to expansion and contraction of the fabric cannot be obtained.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a stretchable woven and knitted fabric having a moving color effect, which is not found in conventional woven and knitted fabrics, and the iridescent effect is changed by stretching during wearing. To provide a manufacturing method.

[0005]

Means for Solving the Problems In the course of studying a woven or knitted fabric having an iridescent effect, the present inventor has arranged two or more differently colored yarns on the surface layer and the inner layer of the woven and knitted fabric, and The present invention has been completed by finding that when stretchability is applied to the woven and knitted fabric, the yarn density of the surface layer changes due to expansion and contraction of the woven and knitted fabric, the visible ratio of the yarn in the inner layer changes, and a very fascinating iridescent effect with movement is obtained. Came to do.

That is, according to the present invention, the elastic yarn and the two or more types of non-elastic yarns are arranged, and the two or more types of non-elastic yarns are arranged at different positions in the thickness direction of the woven or knitted fabric, and There is provided a stretchable woven or knitted fabric having an iridescent effect, characterized in that the two or more types of non-elastic yarns are colored in different colors.

Further, according to the present invention, a knitting machine of three sheets is used and knitted by disposing elastic yarns in the back and the non-elastic dyes in the middle and the front respectively. Then, there is provided a method for producing a stretchable knit, wherein the non-elastic yarns are dyed differently with different dyes.

The elastic yarn used in the present invention is for imparting a dynamic bead effect while imparting elasticity to the woven or knitted fabric when worn, and polyurethane elastic yarn, polyether ester elastic yarn or the like is used. I can. However, considering the heat resistance when dyeing a non-elastic yarn to be mixed, a polyetherester elastic yarn excellent in wet heat resistance is preferable.

The two or more types of inelastic yarns used in the present invention are
It may be undiluted or dyed in different colors in advance, but after weaving and knitting by combining different dyed non-elastic yarns, one yarn is dyed but the other yarn is not dyed. In this case, the woven and knitted fabrics can be dyed in different colors, which is convenient for manufacturing the woven and knitted fabric at low cost.

Examples of such combinations include cationic dye dyeable polyester and acid dye dyeable polyester, cationic dye dyeable polyester and nylon, polyester and acrylic fibers, polyester and cellulose fibers, nylon and cellulose fibers, and the like. You can

In order to dye these two or more types of inelastic yarns separately, they may be dyed with dyes of different colors, but at least one type of inelastic yarn should be dyed in many colors. You can also

A woven or knitted fabric which is dyed separately by a combination of printing or dip dyeing (ground dyeing) and printing shows an extremely fantastic movement of a beetle effect. In addition, even if the colors to be printed (coloring) are exactly the same, if the background dyeing color changes, it looks like a completely different printing color, which is extremely convenient in terms of product diversification.

In the stretchable woven or knitted fabric of the present invention, two or more kinds of non-elastic yarns are arranged at different positions in the thickness direction of the woven or knitted fabric, and the non-elastic yarns constituting the surface layer of the woven or knitted fabric are When the other non-elastic yarns located in the inner layer are appropriately covered and the woven or knitted fabric is expanded or contracted, the degree of the covering is reduced to expose more colors of the non-elastic yarns in the inner layer.

Since the woven or knitted fabric of the present invention is stretched by the elastic yarn, the degree of coverage of the surface layer with the non-elastic yarn when stretched is inevitably reduced, and the non-elastic yarn positioned in the inner layer is reduced. Will be exposed. As a result, a peculiar color effect in which the iridescent effect changes due to expansion and contraction can be obtained.

The arrangement position of the elastic yarns and the non-elastic yarns in the woven or knitted fabric, the ratio of the interwoven and knitted fabrics, etc., depend on the stretchability, the color, and the bead effect (how much the bead effect changes when the fabric is stretched). It can be selected as appropriate.

When a highly transparent yarn is used as the non-elastic yarn located on the surface layer, a gloss effect is added to the peculiar color effect of the present invention, and a very attractive effect is obtained. In particular, when the highly transparent yarn has a relatively thick single yarn denier and has a cross-sectional shape such as a triangle, a rectangle, a pentagon, and a hexagon that easily causes specular reflection depending on the angle, the gloss effect is , More desirable.

The stretchable woven or knitted fabric of the present invention can be knitted and woven using any conventionally known knitting machine for interwoven knitting.

For example, by using a warp knitting machine of three sheets, elastic yarn (for example, polyetherester fiber) is used for the back and non-elastic yarns having different dyeability are used for the front and the back respectively (for example, medium back). Then, a cationic dye dyeable polyester and a nylon fiber are knitted on the front and knitted, and then each non-elastic yarn may be dyed differently with different dyes.

[0019]

Since the woven or knitted fabric of the present invention contains the elastic yarn,
Has elasticity. Furthermore, in the woven or knitted fabric of the present invention, the non-elastic yarn constituting the surface layer and the non-elastic yarn constituting the inner layer are
Since each of them is colored in a different color, and the surface layer threads usually cover up the inner layer threads, the color of the surface layer threads is mainly visible, but when the woven or knitted fabric is stretched, the surface layer threads are Since the degree of covering the yarn of the inner layer decreases, the color of the inner layer of the yarn appears and disappears between the yarns of the surface layer, and the so-called iridescent effect is developed. It will produce a certain color effect.
