Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double or triple multiplex fabric suitable for infants, hygiene and the like.

[0002]

2. Description of the Related Art Conventionally, gauze fabrics having a plain weave texture have been widely used as underwear for children and towels.

However, in this gauze fabric, cotton yarn is used, and necessary twists are added so that troubles such as yarn breakage do not occur in the weaving process, the surface has a rough and hard feeling, and the skin is thin. There was a problem that was not always suitable for weak infants.

Further, as shown in FIG. 7, there is a double gauze fabric composed of a surface fabric C and a back fabric D, but similarly, since it is a thin fabric lacking in flexibility, it has a poor heat insulating and hygroscopic property and is simple. Since it is a plain weave structure, there are problems such as lack of fashionability of products.

[0005]

Therefore, it has been attempted to weave a non-twisted yarn having flexibility and a feeling of volume, but the yarn breaks during the weaving process and it is practically impossible to weave.

Therefore, an object of the present invention is to provide a multi-layered woven fabric which uses soft untwisted yarn and is soft, thick and voluminous, excellent in heat retention and hygroscopicity, and has a pattern formed on the surface to enhance fashionability. Is to provide.

[0007]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention relates to a surface woven fabric having a pattern structure in which a processed untwisted yarn obtained by covering a fiber bundle with a melted yarn is woven, and a backing fabric made of ordinary yarn. By this, the multiple woven fabric was formed. Gauze fabric can be used for this backing fabric.

The processed untwisted yarn is used as a warp yarn for the surface fabric, and a ridge made of the processed untwisted yarn is provided on the surface of the surface fabric. Further, the surface and back fabrics have a thickness of 1
A warp yarn and a weft yarn of -60 count were used, and the weaving density of each was woven at 10 yarns / inch to 60 yarns / inch. It is preferable to use cotton threads for these surface and back fabrics.

[0009]

The multi-layered woven fabric according to the present invention can be woven by covering the sliver-shaped untwisted yarn, which is cut off immediately when pulled, by covering with the melted yarn, and the processed untwisted yarn is exposed in a ridge pattern on the surface fabric. After that, since most of the melted yarn is naturally removed in the water washing step of the finishing process, the sliver-like untwisted yarn expands into a cotton shape and becomes bulky.

For this reason, the surface is soft and the thickness is increased to generate a preferable volume. Further, various patterns of ridges can be woven on the surface fabric, and a woven fabric rich in fashion can be obtained.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, FIG. 2 and FIG. 3, the multiple woven fabric of the present invention has a ridged weave structure in which warp yarns of processed untwisted yarns 1 and weft yarns of ordinary yarns (single yarns) 2 are crossed with each other. Fabric A,
It is woven from the warp yarn of the plain yarn 3 and the back fabric B in which the weft yarn of the plain yarn 4 is crossed, and the outer cloth A and the back fabric B are connected and integrated at the knotting portion 5 (see FIG. 3) at a key point. It is a thing.

The processed untwisted yarn 1 is, as shown in FIG.
A sliver-like fiber bundle 6 formed in the process of a card machine or a comb machine is wound around a sliver-like fiber bundle 6 with melted yarns 7 made of water-soluble vinylon fibers, alginic acid fibers or the like in a spiral shape at intervals to provide covering covering.

The processed non-twisted yarn 1 has a flexibility and a bulkiness as a fiber bundle 6 in which natural fiber 100% is mixed with artificial fiber fiber having an irregular cross section such as hollow or polygonal fiber in natural cotton. , Can be further increased. Moreover, you may use acrylic fiber as needed. As the processed untwisted yarn 1, a yarn for 1st to 80th count can be appropriately selected according to the application.

The above-mentioned ordinary yarns 2, 3 and 4 are spun yarns (single yarns) made of 100% cotton, but are 1-60 count, preferably 1 yarn.
Those having a number of 0 to less than 45 can be appropriately used. In addition, acrylic yarn can be used.

In the surface fabric A, for example, the warp ridges 8, 8, 8 in which five weft yarns are skipped and floated only on the combination surface of the processed non-twisted yarns 1, 1, 1 of three warp yarns are alternately arranged. 5 /
It is woven in a checkered pattern with 5 single-sided satin, and one of the three in this combination is shifted by one stitch and intersects with the weft thread to firmly retain the adjacent ridges.

In this multi-layered fabric, the relatively long ridges are used as the surface fabric A.
The sliver-like fibers at the core of the processed untwisted yarn 1 expand into a cotton-like shape and become bulky, as the melted yarn largely dissolves away naturally during washing with water such as scouring and bleaching. Is soft and the thickness of the fabric is increased to give a preferable volume feeling. Even if the melted yarn is melted away to form a sliver, the ridges 8 are supported at the intersections with the weft yarns before and after the ridges, so that the cotton fiber does not fall off during use.

The surface fabric A has a combination of three processed untwisted yarns 1 for forming the ridges 8 in addition to 2 to 5
It is possible to select a book and to select 3 to 8 weft-thread skippers. Further, the weaving density of the surface fabric A can be increased by increasing the weaving density from 10 threads / inch to 60 threads / inch, preferably from 30 threads / inch to 50 threads / inch, to make the ridges dense. In combination, a feathery surface is obtained and flexibility is increased.

In the surface fabric A, all the warp yarns are processed untwisted yarns, but it is also possible to mix ordinary yarns in a required ratio, for example, one in four yarns. And the durability is improved. In addition, the back fabric B is
Although a plain weave gauze fabric is shown in FIG. 2, in addition to plain weave, satin weave, twill weave, other strange weaves, and fabrics having a changed structure can be used. However, pile fabrics are not suitable.

In the multi-layered woven fabric, when the yarn for the surface fabric A and the yarn for the back fabric are combined, the processed untwisted yarn is 35 to 40 in weight ratio.
%, It is preferable that the normal yarn is 60 to 65%. As described above, in addition to the double woven fabric, a triple woven fabric can be used depending on the application, and further, the processed untwisted yarn is used for the weft yarn. It can also be woven into those provided with horizontal ridges.

FIG. 5 is a structural diagram showing a surface woven fabric of another embodiment of the multiplex fabric of the present invention, in which five warp-processed untwisted yarns 9 are combined, and only five surface weft yarns are skipped and floated. The vertical ridges 10 are woven in a 5/5 one-sided satin diagonal pattern pattern.

FIG. 6 is a structural diagram showing a surface fabric of still another embodiment of the multiplex fabric of the present invention, in which five warp-processed untwisted yarns 11 are combined and seven weft yarns are skipped and floated only on the surface. The vertical ridges 12 are woven in a 7/1 single-sided satin lattice pattern.

As described above, the multiple woven fabric of the present invention can be freely woven with various patterns and weave patterns on the surface woven fabric A to enhance the fashionability, and the weaving density of 10 warps on both the warp and the weft. The thickness can be appropriately selected within the range of / inch to 60 lines / inch. Further, if necessary, the processed non-twisted yarn can be used for the back fabric.

[0024]

As described above, according to the present invention, the processed untwisted yarn in which the sliver-like fiber bundle is covered with the melted yarn and reinforced is woven to form a relatively large ridge on the surface of the surface fabric. In addition, troubles such as yarn breakage do not occur during weaving, normal weaving is possible, and most of the melted yarn is naturally melted away by washing with water in the finishing process such as scouring and bleaching after weaving. It expands into a soft sliver-like fiber bundle and becomes bulky, and it has a favorable volume feeling, excellent heat retention and hygroscopicity, and is useful as infant's underwear, mini handkerchiefs, towels, sheets, bedding covers and hygiene products. .

Further, a woven pattern such as a floral pattern can be easily provided on the surface by the ridges, and a highly fashionable woven fabric can be provided.
