The excellent properties of polyurethane: prominent high resilience, polyurethane high resilience is
the all elastic fiber can not be compared, its elongation at break of more than 400%, up to a
maximum of 800%, even in 300% tensile deformation, springback reply rate is above 95%;
good tensile strength, tearing strength; weather resistance, ultraviolet radiation ability; chemical
resistance, resistant to washing; and dye affinity is good.
Lycra spandex has been widely used in textiles, is a new type of high value-added textile material,
