DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a woven fabric having a double-layer woven structure, and more particularly, to a surface layer in which synthetic fibers are exposed, and a back layer has cotton fibers having both moisture absorption and quick drying properties. The present invention relates to the construction of a woven fabric having a double layer superimposed weave.

[0002]

2. Description of the Related Art Fabrics are mainly used for fabrics, but in addition to tents, curtains, rain gear, footwear, and the like, there are various other uses. Such a variety of uses,
Fabrics having different functions on the front side and the back side, for example, fabrics made of synthetic fiber on the front side to improve dyeability and cotton on the back side to improve the feel and moisture absorption are not found.

[0003] Of course, the overlapping weaving in which one or both of the warp and the weft are doubled or more is well known, for example, used for a backstriped umbrella or the like. If the synthetic fiber is exposed on the front side and the cotton fiber is exposed on the back side, the above-described cloth can be obtained for the time being.

[0004]

In the double-layer woven structure constructed as described above, the fibers on the back side are partially exposed on the front side, and the fibers on the front side are partially exposed on the back side. I do.
For this reason, when dyeing the synthetic fiber on the front side, there is a disadvantage that the exposed cotton fiber on the rear side is not dyed. In addition, when this fabric is used for a kimono fabric and the lining side comes into contact with human skin, it is difficult to absorb sweat, and there is also a disadvantage that the fabric is sticky. The present invention eliminates such disadvantages,
An object of the present invention is to provide a double-layer woven structure which has good dyeing characteristics on the front side, has high hygroscopicity on the back side, and can quickly release the absorbed moisture.

The present invention provides a double-layered fabric which is a nonwoven fabric of cotton yarn, wherein a fabric on a surface layer and a fabric on a back side are adhered. In a double-layer fabric integrally formed of heterogeneous fibers, the surface layer is a synthetic fiber woven fabric that can be easily dyed, and the back side is a cotton yarn to which ceramic fine particles having pores that increase the surface area are fixed. A double-layered fabric characterized in that the surface layer and the fabric on the back side are bonded to each other. And in these double-layered woven fabrics, a double-layered woven fabric in which the surface fibers are subjected to a waterproof treatment is also provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a layered weave diagram of a double-layer woven fabric according to the present invention, showing a cross section of the woven fabric. In FIG. 1, a circle represents a warp, and a square represents a weft. The numbers shown in the circles or squares indicate the type of yarn. In the figure, numerals 1, 3, 5, and 7 indicate synthetic fiber polyester yarns, and numerals 2, 4, 6, and 8 indicate cotton yarns excellent in moisture absorption and moisture dissipation.
As can be seen from FIG. 1, the wefts located on the front side of the woven fabric 1 are all polyester fibers, and the wefts located on the back side are cotton threads excellent in moisture absorption and moisture dissipation.

The above-mentioned cotton yarn excellent in moisture absorption and divergence of water is
Innumerable ceramic fine particles having a diameter of about several microns are chemically bonded and fixed on the surface and in the scale. Fine crack pores are provided on the surface of the ceramic fine particles, and the fine particles have a surface area about 1800 times that of a spherical ceramic ball having the same diameter. For this reason, when moisture adheres to the surface of the ceramic fine particles, it is rapidly absorbed into cracks on the surface by capillary action. The absorbed moisture becomes steam by the heat given by the ceramic fine particles, and evaporates immediately from this crack to the outside as steam. Heat is always supplied to the ceramic fine particles from the atmosphere or the human body. The details of the cotton yarn excellent in moisture absorption and moisture dissipation are described in JP-A-6-1-1.
No. 16862.

A cotton yarn 2 having excellent moisture absorption and moisture dissipation on the back side,
4, 6, and 8 (wefts) are woven in a plain weave by cotton yarns (warp) 2, 4, which are excellent in moisture absorption and moisture dissipation. However, these cotton yarns 2, 4, 6, 8 are not exposed on the surface of the fabric. Therefore, only the polyester fibers are exposed on the surface side of the fabric.

In the double-layer woven fabric according to the present invention, when dyeing the polyester fiber (synthetic fiber) on the front side, the cotton fiber on the back side is not affected by the dyeing, and the cotton fiber on the back side is dyed. In this case, the fabric can be selectively dyed on both sides without affecting the dyeing of the polyester fiber on the surface side. Therefore, for example, when the double-layer cloth of the present invention is used as the fabric of the awning, the surface can be dyed with vivid colors, and water droplets do not adhere to the inside. In addition, if the double-layer woven fabric according to the present invention is used for athletic shoes, the surface can be constituted by a woven fabric dyed with vivid colors, and the inner side absorbs and diverges sweat well. It can be.

The double-layered fabric according to the present invention can also be provided as a non-woven fabric. That is, as shown in FIG. 2, a polyester fiber is entangled by a dry method or a wet method, a web having a predetermined thickness is formed, and the entangled fibers are adhered to each other with an adhesive to form a nonwoven fabric made of thin synthetic fibers. The layer 30 is formed.

Next, as shown in FIG. 3, the non-woven fabric layer 30 is placed on, for example, a negatively charged electrode plate 31, and an adhesive 32 is thinly applied on the woven fabric layer 30 before it is dried. The above-described cotton yarn excellent in moisture absorption and moisture dissipation is positively charged, then electrostatically adsorbed on the adhesive 32, and bonded to form a nonwoven fabric layer 33 made of cotton yarn excellent in moisture absorption and moisture dissipation. Form. The double-layer fabric made of the nonwoven fabric thus formed is suitable as, for example, a hat fabric.

In the next embodiment, the nonwoven fabric layer 3 shown in FIG.
A woven fabric using polyester fibers is used instead of 0.
In addition, as a method of forming a nonwoven fabric layer made of cotton yarn having excellent moisture absorption and moisture dissipation on this woven fabric, an electrostatic attraction method is used as in the above embodiment. The double-layer woven fabric thus formed is used, for example, as a material for awnings. In addition, if the woven fabric layer using the polyester fiber on the surface is subjected to a waterproof treatment, the fabric becomes more suitable as a tent fabric, and furthermore, as a fabric of a rain feather.

In the first embodiment, both the front and back surfaces are formed of a woven fabric, and they are integrated by weaving. However, they may be bonded with an adhesive.

Although the present invention has been described with reference to the above embodiment, various modifications and applications are possible within the scope of the present invention, and these modifications and applications are not excluded from the scope of the present invention. Absent.
