Abstract

The invention discloses a blocked organosilicone waterborne polyurethane anti-fluffing-and-pilling agent which is composed of, by weight, 20-30 parts of terminated hydroxy modified silicone oil, 7-15 parts of isophorone diisocyanate, 1.5-2.5 parts of dimethylolpropionic acid, 0.2-0.5 part of 1, 4-butanediol, 0.20-0.24 part of dibutyltin dilaurate, 1-2 parts of triethylamine, 10-20 parts of acetone and 90-120 parts of water. The blocked organosilicone water-borne polyurethane anti-fluffing-and-pilling agent prepared is high in film forming strength, compactness and continuity; fabric finished by using the agent is not clammy and free of adhesion with a roller in the process of application, anti-fluffing-and-pilling effect is improved obviously, and the fabric after being finished is good in hand feeling.

Description

technical field [0001] The invention relates to an anti-pilling agent, in particular to a block organosilicon water-based polyurethane anti-pilling agent. The block organosilicon water-based polyurethane anti-pilling agent is mainly used for wool, cashmere fabrics, polyester, cotton Anti-pilling finishing of knitted fabrics and their blended fabrics. Background technique [0002] Polyurethane (referred to as PU), that is, polyurethane, is a polymer compound containing -NHCOO- unit structure. In 1937, German chemist Otto Bayer prepared polyurethane by the addition of isocyanate and active hydrogen compound, thus laying the foundation of polyurethane chemistry. In the 1950s, solvent-based polyurethane coatings were first applied in the dyeing and finishing industry in Europe. With the enhancement of people's awareness of environmental protection, water-based polyurethane has gradually replaced solvent-based polyurethane in recent years, and has developed rapidly in various i...
