Description

The present invention relates to a multifunctional woven fabric.

There are woven fabrics with functionality. For example, Patent Documents 1 and 2 disclose woven fabrics using deodorant fibers.

In a woven fabric having a deodorizing function, it may be desired to add another function in addition to the deodorizing function. For example, cloth gym clothes used in schools contain sweat-containing gym clothes, but odor due to bacterial growth may become a problem, and sweat soaks into the surface of the gym clothes bag. If it squeezes out, it may adhere to the outside. Therefore, it is convenient to have a gym suit bag that has a deodorant function and can prevent sweat from seeping out.

Patent Documents 3 to 20 disclose woven fabrics having water repellency. Generally, a woven fabric having water repellency is obtained by applying a water repellent treatment (for example, dipping) after weaving the woven fabric. With this method, it is difficult to give the fabric other functions in addition to water repellency. Further, a woven fabric having a water-repellent finish works disadvantageously when breathability is required.

Further, in a woven fabric having a deodorant function, it may be desired to impart a function other than the water repellent function. For example, the generation of odor caused by sweat is due to the growth of bacteria, but woven fabrics that have antibacterial function (suppression of bacterial growth) in addition to deodorant function (decomposition of odorous components, adsorption, etc.) It is useful if there is.
