Polyester Bicomponent Yarn M400

M400 by high viscosity of PBT and low viscosity PET composite spinning Is a kind of composite elastic fiber, have permanent spiral curls and excellent fleeciness and elasticity recovery, color fastness and soft hand touch.  It solves the problem that Spandex yarn is not easy to dye, elastic surplus, fabrics size is not stable, and easy ageing, and can be directly use on water jet, air jet loom. The tensile strength of M400 yarn is very good, and the elasticity of M400 yarn is 2~5 times that of ordinary PET filament yarn. Good elastic recovery, even after 500 times of repeated stretching, its elastic recovery rate can maintain more than 95%; It feels soft and comfortable to wear.
