Abstract

The invention discloses a preparation method of a block organosilicon waterborne polyurethane anti-pilling agent, which comprises the following steps: a preparation process of a hydrogen-terminated modified silicone oil; a preparation process of a hydroxyl-terminated block silicone oil; and a block organosilicon waterborne polyurethane A preparation process of an anti-pilling finishing agent. The preparation process of the invention is simple, and the prepared block organosilicon water-based polyurethane anti-pilling agent has high film-forming strength, good compactness and continuity. The finished fabric is not sticky, the application process does not stick to the roll, the anti-pilling effect is significantly improved, and the finished fabric feels good.

Description

technical field [0001] The invention relates to a preparation method of an anti-pilling agent, in particular to a preparation method of a block organosilicon water-based polyurethane anti-pilling agent. The block organosilicon water-based polyurethane anti-pilling agent is mainly used for wool, Anti-pilling finishing of cashmere fabrics, polyester, cotton 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 rece...
