Study of Polyurethane Used for Temperature-sensitive Waterproof and Breathable Fabric(1)

A polyurethane coating agent with crystalline soft segment was synthesized through the adjustment of polyurethane composition and proportionality.With the test and analysis of polyurethane's performance,it confirmed that this polyurethane agent has sensitive response to environment temperature,and its crystal fusing temperature is in the range of 15～21℃,at which human will feel very comfortable.
