Synthesis and application of modified aqueous polyurethane woolshrink-resisting agents

In this paper, Isophorone Diisocyanate(IPDI) and polyether polyol were selected as experimental raw materials. And a series of aqueous polyurethane wool shrink-resisting agents were synthesized. As the stiff handle of wool fabric treated with water based polyurethane, hydroxyl silicone was added into the reaction system to improve the stiff handle.
