Abstract: Shape memory polyurethanes with different concentrations were applied on nonwoven fabric by using coating technology,and the surface structure,shape and wrinkle retention,air and moisture permeability,and tensile strength of the nonwoven fabrics before and after coating were tested.The results showed that the coated nonwoven fabrics have good shape memory and better crease resistance.The less content of polyurethane has little effect on the moisture vapor transmission of the coated fabric,but results in marked decline of its air permeability.
