Chinese Patent Publication No. CN 101798750 A, the publication date is August 11, 2010, and the title of the invention is "An Anti-ultraviolet Finishing Method for Cotton Fabrics with Nano-Si-based Oxide". The method combines nano-Si-based oxide with synthetic Latex is used to form a nano-silicon-based oxide film on the fabric, thereby endowing the cotton fabric with excellent UV resistance, but the washing resistance of the fabric and the loss of physical and mechanical properties of the fabric are worthy of attention
Chinese Patent Publication No. CN 103469560 A, the publication date is December 25, 2013, and the title of the invention is "A Method for Finishing Anti-ultraviolet Pure Cotton Fabric", which combines inorganic silica and organic 2,4-dihydroxybenzophenone Ketone, N, N-di-n-butyldithiocarbamate nickel organically combined, selected specific additives compounded, so that the fabric has the advantages of two anti-ultraviolet finishing agents, but the fabric and finishing The combination between the agents is not firm and the durability is poor
Chinese Patent Publication No. CN 103757929 A, the publication date is April 30, 2014, the title of the invention is "An antibacterial, anti-wrinkle, anti-ultraviolet cotton, polyester-cotton fabric finishing method", pure cotton, polyester-cotton fabrics are made of HFXZ -881, ester quaternary ammonium salt, silane copolyol, zinc nitrate, pure water, anti-ultraviolet agent E, sodium hypophosphite, diethylene glycol diglycidyl ether, isopropanol, pentaerythritol fatty acid ester, maleic anhydride, lemon The acid is prepared by three padding treatments. The cotton and polyester-cotton fabrics treated by this method can reach 7 grades of antibacterial, 5 grades of UV resistance, and 4 grades of wrinkle resistance for more than 12 times of washing, and have excellent durability and washability. Sex, but its anti-wrinkle effect is still not particularly ideal

Abstract

The invention relates to a preparation method of a functional fabric, and belongs to the technical field of textile materials. Functional nanoparticles are compounded on the surface of the fabric through the preparation of the functional nanoparticles and the preparation of the functional fabric. The existence of vinyl polysiloxane overcomes high adsorption capacity of functional nanoparticle aggregate, so that the uniformly dispersed functional nanoparticles are firmly adhered to the surface of the fabric, and the fabric has multiple functions of ultraviolet resistance, super-hydrophobicity, pollution resistance, antibacterial property, health and the like through the synergistic effect of the vinyl polysiloxane and the functional nanoparticles. According to the preparation method of the functional fabric disclosed by the invention, the vinyl polysiloxane is efficiently utilized, the productive value of the vinyl polysiloxane is improved, and the application of the vinyl polysiloxane to other fields is developed; moreover, the whole process is simple in equipment, relatively low in cost and free of pollution to ecological environment, and has a great application prospect.

Description

Background technique [0002] The production of textile materials occupies an important position in the national economy and people's lives. In recent years, with the continuous advancement of science and technology, the fiber industry has developed rapidly. Textile materials have become more and more colorful, with increasing varieties and improved performance. People have higher and higher requirements for the functionality of textiles, which only have one or two functions. High-quality fabrics can no longer meet the various needs of people. In addition to textiles used in clothing and interior decoration products, the demand for textiles with special properties and industrial textiles is also increasing, and newer and higher requirements are also put forward for the performance of textiles.
