Abstract: A series of blocked aliphatic waterborne polyurethane emulsions were prepared with isophorone-
diisocyanate (IPDI), polyether polyols, dimethylolpropionic acid (DMPA) as materials and NaHSO 3 as blocking age-
nt. The influencing factors of the pre-polymerization reaction, neutralization reaction and blocking reaction were
investigated and the synthetic process conditions were optimized. Then the blocked aliphatic waterborne
polyurethane (WPU) with prehensive properties were obtained. The WPU was used to anti-crease fini-
shing of cotton fabric. The results showed that the wrinkle recovery angle of the treated fabric were increased
and the strength retention were also enhan
