PBT filament yarn Heshili PBT stretch yarn is a new fiber that developed by Heshili in 2010.This product feels soft and has many characteristices,such as good humidity absorbing,easy coloring under the normal temperature, especially the outstanding stretch recovery property,which can meet the needs of the elasticity of the fabrics basically.The appearance of this product can solve many problems that appear in the process of using Polyurethane fibers,such as the bad dyeability,over streched,weaving complex,bad dimensional property and the aging problem. Heshili PBT strech yarn is widely used in the fabric of jeans,swimming wear,shirt,underclothes and pants.It is also an upgraded product of Polyurethane core spun yarn.

Performance: Tetrahydrofran(THF),is an import organic synthetic raw materials and excellent solvemnt.Since the polycondensation into four sub-polyethylene glycol methl ether(PTMEG),to the production of polyurethane elastomer,polycondensation elastomer,polyurethane fibers(spandex),special rubber,and some special-purpose coating materials;also be used to product tetrahydro-thiophere,1,2-Dichloroethane,2,3-Dichloro-Tetrahydrofuran Ecaprolactone,butyrolactone and pyrrolidone,such as chemical intermediates.In Chinese medicine field,it is used for synthesis of synthesis of anti-infective drugs and hormonal drugs,but also the production of important intermediates of vitamin E;also can be used as fuel gas odor agent.

Rapid crystallization, easy molding、Excellent resilience、Excellent heat resistance、High flexural modulus、Excellent chemical stability、Excellent creep resistance、Excellent electrical properties、Excellent wear resistance、Flexible and comfortable touch、Excellent hydrolysis resistance、Backwash excellent elasticity、Good aging resistance.

Performance:
1 high tensile strength, elongation is larger
2 excellent resilience, therefore the knot strength and resistance to deformation of the good.
3 polyamide fiber is fiber textile fiber wear all the best, its wear resistance is 10 times of cotton wool, 20 times, 50 times of viscose fiber
4 in the synthetic fiber is easy to dye
5 with high humidity and corrosion resistance
6 antistatic, flame retardant
