Abstract

The invention discloses a preparation method of a textile waterproofing agent, and belongs to the field of textile waterproofing materials. Nano-silica is modified by coupling agents, owing to small size effects and macroscopic quantum tunneling effects of the nano-silica, fiber breakage can be effectively prevented, the abrasion resistance of a serous membrane is improved, the dispersibility of the nano-silica can be improved, and mallow bark extracting solution is adsorbed by the adsorption performance of the nano-silica. As extracting solution molecules contain much -OH and enter a weave structure of a silk fabric, fibers generate good cohesiveness, and the tensile property and the ultraviolet resistance of the fabric are improved. The preparation method solves the problems of low tensile property and fiber breakage of fabrics due to the fact that waterproofing agents in the present market cannot effectively prevent water.

Description

technical field [0001] The invention belongs to the field of textile waterproofing, and in particular relates to a preparation method of textile waterproofing. Background technique [0002] Textile water repellent belongs to one of the products of textile material auxiliaries. With the improvement of the performance requirements of textiles, auxiliaries that improve the performance of textiles in all aspects have also been developed one after another. In order to meet the normal use of textiles in daily life and in special environments such as rainy days, summer days, high temperatures, and the field, the waterproof treatment of textiles is particularly important. After the textile fabric without waterproof treatment absorbs water and sweat, the water and sweat will penetrate to the back of the textile, which will affect the appearance and comfort of the textile. Water repellent treatment is an important process of textile finishing. Water repellent can endow the surface o...
