Description

Manufacturing method of woven fabric having a heating function {Manufacturing method of exothermic fabric}

The present invention relates to a method for producing a knitted fabric having a function of generating heat under absorption or absorption.

There are many materials that can generate heat under specific conditions. However, in general, the metal carboxyl and acrylate groups of the fiber can generate heat while absorbing moisture.

In the prior art, a fiber having a high hygroscopic group of high hygroscopicity has been introduced to enhance hygroscopic heat-producing performance, which is widely used as a winter textile product and an industrial material requiring high hygroscopicity.

As a method of hygroscopic heat generation to a fiber material, a ceramic material or other hygroscopic heat-generating powder is attached to a fiber surface with a binder, a hygroscopic heat-generating powder is mixed in a fiber spinning step, and a hygroscopic heat generating component is used for post-processing. There is a method of impregnating padding to the fabric.

In the case of the impregnating padding method to the fabric, there is a disadvantage in that the hygroscopic performance is poor due to the method of manufacturing a fabric that can easily absorb moisture and generate heat.

In addition, a method similar to a process of preparing superabsorbent polymers by modifying acrylic fibers may be used. When hydrolyzing a material having a nitrile group and converting it into a carboxyl group, it may give a function of hygroscopic heat generation, which is converted into a carboxyl group. The problem of attaching the polymer and the hydrophilization process to the fiber itself damages the fiber fabric, and in the post-processing process such as dyeing of the fabric, the acrylate fiber has a disadvantage in that the hygroscopic exothermic performance is poor due to alkali treatment.

On the other hand, the acrylic fiber which is responsible for the heating function exhibits a stiff touch, which appears intact in the fabric and has been restricted in its use. In particular, in the case of the facial mask pack for cosmetics is a physical property that is necessary to feel soft and flexible.

On the other hand, in recent years in the fever due to the cold and functional mask pack products have been used, but the hygroscopic heat effect is not excellent, there is a short heat generation time disadvantage. Therefore, there is a need for a method of effectively and durablely introducing fibers and components capable of generating heat absorbing moisture and developing a moisture absorbing heating fabric that can be used semi-permanently.

The present invention has been made in view of the above point and its object is to provide a method for producing a fabric capable of absorbing or hygroscopic heating.

The present invention is to provide a method of fabricating by mixing the natural fibers, such as cotton or tencel fibers into synthetic fibers in order to give flexibility and soft touch to the exothermic fabric.

In another aspect, the present invention is to provide a method for processing the fabric so that the heat generated of the fabric can be effectively exhibited.
