Polyester stretch yarn has the following properties:
1, high strength. The short fiber has a strength of 2.6 to 5.7 cN / dtex and a high strength fiber of 5.6 to 9.0 cN / dtex. Due to low moisture absorption, its wet strength and dry strength is basically the same. Impact resistance than nylon 4 times higher than the viscose fiber 20 times higher.
2, good flexibility. Elastic close to the wool, when the elongation of 5% to 6%, almost completely restored. Wrinkle resistance than other fibers, that is, fabric is not wrinkled, good dimensional stability. Elastic modulus of 22 ~ 141cN / dtex, 2 to 3 times higher than nylon.
3, good heat resistance.
4, good water absorption.
5, good wear resistance. Wear resistance after the best wear resistance of nylon, than other natural fibers and synthetic fibers are good.
6, good light resistance. Light resistance after acrylic.
7, corrosion-resistant. Resistant bleaching agents, oxidizing agents, hydrocarbons, ketones, petroleum products and inorganic acids. Resistant alkali, not afraid of mold, but the hot alkali can make it decomposition.
8, poor dyeing.
