Problems solved by technology

Although the above two methods can obtain a good hydrophobic surface, they are only the simulation of the single microstructure of the micron rough structure on the surface of the lotus leaf; The cleaning performance needs to be further improved, and more importantly, these fabrics are difficult to endow the fabric with more functions

Abstract

The invention discloses a preparation method of super water-repellent and oil-repellent fabric. The preparation method comprises the following steps: selecting ultrafine fibers as raw material, improving the micron-structure roughness of the fabric by using crepe weaves and adding high-shrinkage filaments to the fabric, simultaneously grafting low surface-energy substances on the surfaces of the fibers, treating the fabric by using a nano-particle finishing agent to cause a nano-sized coarse structure to be formed on the surface of the fabric, and preparing the super water-repellent and oil-repellent fabric having a mastoid imitating a micron-structure of a lotus leaf and a nano-structure. Therefore, the water-repellent and oil-repellent performance of the fabric is further improved, the fabric is free from water and oil, and the fabric has self-cleaning performance. The fabric prepared by the method has high moisture permeability, air permeability, drapability and wrinkle resistance, and can be used for producing Western-style clothes, work clothes, raincoats, ski suits, military uniforms and the like besides sports clothes.

Description

technical field [0001] The invention belongs to the technical field of functional clothing fabric processing, and relates to a preparation method of textile fabrics, in particular to a preparation method of super water-repellent and oil-repellent fabrics. Background technique [0002] In the 1990s, Barthlott and Neinhuis, botanists at the University of Bonn in Germany, observed the microstructure of the lotus leaf surface and believed that the self-cleaning properties of the lotus leaf surface were caused by the papillae of the rough surface microstructure and the presence of waxy substances on the surface. of. Recently, Jiang Lei of the Chinese Academy of Sciences and his experimental team published the research results, and believed that there are nanostructures on the papillae of the microstructure on the surface of the lotus leaf. root cause of water surface. Moreover, the super water-repellent surface has a larger contact angle and a smaller rolling angle. [0003] T...
