Abstract

The invention discloses textile anti-pilling polyurethane finishing agent. The textile anti-pilling polyurethane finishing agent is made by the reaction of the following raw materials on a mass percent basis: 11.74-21.3% of polypropylene carbonate polyhydric alcohol, 3.81-10.2% of diisocyanate, 0.014-0.036% of catalyst, 0.9-1.864% of chain extender, 2.1-2.78% of organic solvent, 3.7-8.2% of amino silicon oil, 0.7-1.19% of neutralizer and 59.6-70.5% of deionized water, and the total content of the components is 100%. The invention further relates to a preparation method of the finishing agent, and the preparation method includes the steps of weighing the raw materials, preparing polyurethane prepolymers, preparing amino silicon oil grafting modification polyurethane, and finally adding the deionized water and the neutralizer into the amino silicon oil grafting modification polyurethane to obtain the finishing agent. The finishing agent can improve the anti-pilling property of textile and enable the textile to be soft.

Description

technical field [0001] The invention belongs to the technical field of polymer material synthesis and application, and specifically relates to an anti-pilling polyurethane finishing agent for textiles, and also relates to a preparation method of the polyurethane finishing agent. Background technique [0002] Knitted textiles have low yarn twist and loose tissue structure, and the surface of the fabric tends to have free fiber fluff. Knitted textiles are subject to friction during wearing and washing, and fibers tend to slip from the yarn and free on the surface of the fabric, and the fibers further collude and entangle with each other, resulting in pilling. The pilling of knitted textiles seriously affects the wearability and aesthetics. [0003] At present, many researchers have done more research and reports on the anti-pilling finishing of polyurethane and silicone-modified polyurethane on knitted fabrics. The publication number is: CN102505490A, the title of the invent...
