Problems solved by technology

This is determined by its surface energy. Some rubber-type finishing agents developed in the future are coated on the surface of the fabric in the form of coatings. These coatings have both waterproof and oil-proof effects, but they are characterized by sealing systems. , the fabric may lose its original air permeability, and when worn as clothing, it will feel stuffy due to airtightness, greatly reducing the comfort of wearing

Abstract

The invention discloses a preparation method of a highly hygroscopic oil-repellent pure cotton fabric. The oil-repellent fabric comprises a fabric layer and an oil-repellent layer, the fabric layer is made of cotton fibers, and the oil-repellent layer is sprayed on the fabric layer; the highly hygroscopic oil-repellent The preparation method of the fabric includes the configuration process of the oil-proof coating liquid, the UV-induced coating reaction process, the heterogeneous graft copolymerization reaction process, and the post-treatment process. The pure cotton fabric modified by the invention not only has oil-repellent performance, but also makes up for the consumption of hydroxyl groups in cellulose, thereby maintaining the hygroscopicity of the fabric.

Description

technical field [0001] The invention belongs to the field of textile fabrics, and in particular relates to an all-cotton composite functional fabric with oil-proof and high moisture-absorbing properties. Background technique [0002] In recent decades, according to the development trend of textiles at home and abroad and the needs of people's lives, more and more people pay more and more attention to multi-functional products with high technical content. For more and more textiles such as clothing fabrics, non-woven fabrics, decorative textiles, carpets, industrial textiles, etc., multi-functional finishing such as oil-proof, anti-fouling, flame-retardant and radiation-proof, without changing the fabric's air permeability, The application of properties such as moisture permeability is becoming more and more extensive, which has attracted people's attention. [0003] Before fluorocarbons were used as waterproof and oil-repellent agents, organosilicon compounds were used to a...
