Huahai spandex is a high-class elastic fiber with the following features:

1) Highly elastic, thin, long stretch, low specific gravity, low ammonia content

2) High strength, high elastic modulus, breaking elongation may reach 550%

and above, good wear resistance

3) High temperature resistant, heat setting temperature 190?, good

chromaticity

4) Even denier, low tensile stress, high elastic recovery percentage, good for

medium and high-class fabrics
