Problems solved by technology

[0006] Although this patent can improve the uncomfortable feeling of stickiness, however, the water-swellable layer will cause the wearer's skin to always have the uncomfortable feeling of the presence of foreign matter
Furthermore, after the shape-changing fiber cloth is washed many times, the water-swellable layer is easy to fall off from the fiber cloth layer, so that the service life of the shape-changing fiber cloth does not meet the requirements.

Abstract

A moisture-absorbing cool-feeling fabric and a method for making the moisture-absorbing cool-feeling fabric. The moisture-absorbing cool-feeling fabric contains a fabric body including a plurality ofinterlaced yarns and a plurality of hydrogel microbeads pressed and trapped between the yarns of the fabric body. The hydrogel microbeads are pressed and trapped between the yarns of the fabric body,so that when a wearer wears the moisture-absorbing cool-feeling fabric, discomfort of foreign matter existence does not occur, and when the hydrogel microbeads absorbs moisture or sweat generated by the wearer, a plurality of protruding parts at intervals are formed on the surface of the moisture-absorbing cool-feeling fabric and the plurality of protruding parts define a channel. Discomfort of wetness stickiness is improved through the protruding parts, and besides, effects of drying and cooling are achieved through moisture or sweat absorption by the hydrogel microbeads and the channel.

Description

technical field [0001] The invention relates to a cloth, in particular to a moisture-absorbing cool-feeling cloth and a method for preparing the moisture-absorbing cool-feeling cloth. Background technique [0002] As people's requirements for the comfort of clothes are getting higher and higher, the characteristics of clothes such as hygroscopicity, quick drying and non-sticky skin have become extensive research topics, especially when the clothes absorb the moisture generated by the wearer When sweating or sweating, because the clothes will be adsorbed on the wearer's skin, the skin will produce wet and sticky discomfort. [0003] In order to improve the discomfort, Chinese Taiwan Patent Publication No. 201326491 discloses a structure of a unidirectional moisture-absorbing and perspiration-wicking fabric, which includes a first rayon with a moisture-absorbing agent on its surface and a water-repellent coating on its surface. The second artificial fiber of the agent, wherei...
