The spevial asymmetric cooling forming technologies adopted makes the fiber a "permanet" spiral three-dimensionalcrimp.
The product has the charactreistics of high loftiness, high hollow rate and highresilience. Hollow fiber ensures excellent warmth and hydrophobicity. It has many characteristics better than natural fibers, including softness and smoothness, light weight, sanitation, no harmful substance retention and diffusion, corrosion resistance.
