Abstract

The invention relates to a one-way moisture-guiding asymmetric polyester fabric and its preparation and application. Preparation: the mercapto-modified polyester fabric is immersed in a finishing solution mixed with 3-sulfopropyl acrylate and a photoinitiator, and is exposed to one side of ultraviolet light Under the irradiation, that is. The invention utilizes the click chemical reaction to form a chemical bond combination between the fabric and the hydrophilic finishing agent, effectively improves the moisture-conducting performance of the polyester fabric and has durability after washing.

Description

technical field [0001] The invention belongs to the field of unidirectional moisture-guiding fabric and its preparation and application, in particular to a unidirectional moisture-guiding asymmetric polyester fabric and its preparation and application. Background technique [0002] As the largest synthetic fiber, polyester has many excellent properties and is cheap, so it has an irreplaceable position in national life. However, polyester has poor hygroscopicity, and wearing it in hot summer will give people a stuffy feeling, which limits the development and application range of polyester. As one of the most basic performance indicators of clothing, the thermal and wet comfort of clothing has always been a hot spot of concern for researchers all over the world. The moisture permeability of the fabric is an important factor affecting the comfort of clothing, especially in hot environments or when the wearer is exercising vigorously, the skin will secrete a lot of sweat. If th...
