  Abstract

Non-ionic water-borne polyurethane HSi-WPU was synthesized with isophorone diisocyanate and self-synthesized polysiloxane block polyether as raw materials, with diethylenetriamine utilized as an internal crosslinking agent. The effects of reaction conditions were intensively studied, as molar ratio, reaction temperature, reaction time, and diethylenetriamine dosage on the properties of HSi-WPU were discussed to optimize the synthetic condition and applied the optimal synthetic HSi-WPU to the anti-shrinkage finishing of wool fabric. The chemical structure of HSi-WPU was confirmed via FT-IR and 1H NMR. Good thermal stability of HSi-WPU was noticed, with decomposition of the polymer starting at 300 °C. Surface morphology analysis demonstrated that the wool scale was covered by a thin layer of HSi-WPU film. The anti-shrinkage property of wool fabric finished with HSi-WPU was significantly improved.
