Description

The present invention relates to a woven fabric and a method for producing the same.

As a method of coloring the woven fabric, a paint containing fine powder of charcoal acting as a coloring member and a binder is applied to the woven fabric, and then the applied paint is heated at a predetermined temperature to form the surface of the woven fabric with charcoal. A method of providing a printed pattern to be printed has been proposed (see Patent Document 1 below).

It is said that the woven fabric colored by the method described in Patent Document 1 can give the woven fabric an effect such as a deodorant effect of charcoal while forming a printed pattern having a desired shape.

However, the coloring method described in Patent Document 1 is to color the surface of a woven fabric formed of unbleached (uncolored) yarn by fixing fine powder of charcoal with a binder, and the fabric is used for a long time. When the fine powder of charcoal, which is a coloring member, is peeled off from the woven fabric, the unbleached color (colorless) of the threads forming the woven fabric is exposed on the surface, giving a "tired feeling" to the intended purpose. Become.

Further, as another method for coloring the woven fabric, a method has been proposed in which any of the warp, weft and pile yarns forming the woven fabric is colored with a dye, and any of the remaining yarns is colored with a pigment. (See Patent Document 2 below).

In the woven fabric colored by the method described in Patent Document 2, the color of the yarn colored by the dye is hard to fade, but the pigment is fixed to the surface of the corresponding yarn by the binder, so that the pigment is used. Will peel off from the surface of the corresponding yarn due to long-term use, similar to the coloring method described in Patent Document 1.

Also in the method described in Patent Document 2, the pigment is fixed to the unbleached (uncolored) yarn by the binder, and therefore, when the pigment is peeled off from the surface of the yarn with aging, it is unbleached (unbleached). The colored threads will be exposed on the surface, giving a "tired feeling" to the intended purpose.
