Technical Field
The invention belongs to the technical field of fabric textile, and particularly relates to a three-dimensional fabric with a cool feeling function, and a preparation method and application thereof.
Background
Because people are easy to sweat during exercise, sweat can not be discharged in time when the people wear common clothes so as to stick on the skin because the sweat wets the clothes, and the requirements of the people on health and comfort can not be met. The existing cool clothes are clothes made of cool functional fabrics developed to meet the wearing comfort requirements of people. Various cool fibers are developed for developing cool clothes. The cool fabric has the main forms that: through the grooves on the surface of the fiber, moisture and sweat on the surface layer of the skin are quickly absorbed, transmitted and diffused to the surface of the clothing material and then emitted out. The heat is absorbed in the process of moisture dissipation, and the cool effect is generated. Meanwhile, some cool powder with cool effect is added into the fiber in a melting way. When the skin-care product is contacted with the skin of a human body, the skin is cool and refreshing, and the heat dissipation effect is achieved.

The twill weave is used, the cool yarn floats longer, and the number of times of interweaving the warp and weft yarns is large, so that when a consumer uses the fabric, the skin is in contact with the modified nylon 6 with the ice-cold characteristic, and a good cool effect is achieved.
CN111058168A discloses a method for preparing a knitted fabric with moisture absorption, sweat releasing and continuous cool feeling functions, which comprises the steps of taking chemically modified and physically modified polyester filaments as raw materials, adopting a weaving process and a dyeing and finishing process, designing the knitted fabric into a honeycomb or mesh double-sided structure, and preparing a printing paste by adopting a cool feeling finishing agent with strong cool feeling effect and water washing resistance.
