Abstract

The invention discloses a durable, antistatic and dustproof finishing agent for flocking fabrics. The finishing agent is prepared by matching, by weight, 50-100 parts of methyl hydrogen silicone oil, 70-120 parts of allyl polyethoxy polypropoxy ether, 1.5-5 parts of vinyl trialkoxy silane and 0.1-0.16 part of chloroplatinic acid ethanol solution, making the materials subjected to addition reaction to obtain silicone oil co-modified by polyether and alkoxy, adding 480-820 parts of water for dilution and adding 10-20 parts of glyoxal aqueous solution and 400-500 parts of guanidine hydrochloride aqueous solution for mixing. The flocking fabrics finished through the finishing agent are soft and smooth in hand feel and have excellent antistatic properties, and the fabric surface is not prone to adsorb dust.

Description

technical field [0001] The invention relates to a durable antistatic and anti-dust finishing agent for flocking fabrics and a preparation method. The finishing agent is composed of polyether modified polyorganosiloxane, glyoxal aqueous solution and guanidine hydrochloride. Background technique [0002] Electrostatic flocking has developed rapidly in my country in recent years because of its unique decorative effect of suede and embroidery, as well as its simple process and low cost. It is especially widely used in shoe uppers, clothing and automotive interior products. Different base fabrics, different fluff, different fluff colors, and different production processes can be processed into flocking fabrics with various handles and styles. [0003] However, flocking fabrics also have some shortcomings during use. For example, dark flocking uppers and clothing are easy to absorb dust during wearing, and it is not easy to remove it by hand, which affects the appearance of flock...
