Abstract

The invention relates to a preparation method of quaternized zinc oxide sol as a textile finishing agent. In the preparation method, the quaternized zinc oxide sol is respectively prepared by taking diallyl dimethyl ammonium chloride, diallyl methyl dodecyl, myristyl, hexadecyl, octadecylselyl ammonium bromide and cetyltrimethyl ammonium chloride as additives and taking diallyl methyl alkyl quaternary ammonium as an additive, the monomers not only have a certain regulating function for the shape of the zinc oxide sol, but also can be used for remarkably improving the dispersion degree of the nano ZnO and reducing the grain size of the nano ZnO and can also be used for improving the performance of a finished textile; meanwhile, the quaternized zinc oxide sol can be subjected to cyclopolymerization with other monomers because of containing non-conjugated diene bonds. The quaternized zinc oxide sol has the bacteriostasis rate of 62-83% and the strength loss rate of 22-29% when being applied to the antimicrobial finishing of a cotton textile, and meanwhile, the quaternized zinc oxide sol has certain ultraviolet resistance.

Description

technical field [0001] The invention belongs to the technical field of fabric antibacterial finishing agents, and in particular relates to a quaternized zinc oxide sol fabric finishing agent and a preparation method thereof. Background technique [0002] The formation of the "green" concept has made the antibacterial, anti-mildew and deodorant finishing of textiles more important. In life, people inevitably come into contact with various bacteria, fungi and other microorganisms. Under suitable external conditions, these microorganisms will multiply rapidly and spread diseases through contact and other ways, affecting people's health and normal life. Work, study and live. Fiber is a porous material, and after superposition and weaving, it will form a multi-layer body with numerous voids, so the fabric is easier to absorb fungi. Antibacterial finishing is to make the fabric have the function of inhibiting the growth of fungi, maintain a hygienic clothing and living environme...
