fdy polyester yarn
fdy fully drawn yarn polyester yarn, polyester full stretch yarn.
product specifications: 55dt ~ 666dt
1, high strength. the short yarn has a strength of 2.6 to 5.7 cn / dtex and a high strength yarn of 5.6 to 8.0 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 yarn 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 yarns, that is, fabric is not wrinkled, good dimensional stability. elastic modulus of 22 ~ 141cn / dtex, 2 to 3 times higher than nylon.
3, heat resistance and thermal stability in the synthetic yarn fabric is the best.
4, polyester surface is smooth, the internal molecules arranged closely.
5, good wear resistance. wear resistance after the best wear resistance of nylon, than other natural yarns and synthetic yarns are good. 6, good light resistance. light resistance after acrylic.
7, corrosion-resistant. resistant bleach, hydrocarbons, ketones, petroleum products and inorganic acids. resistant alkali, not afraid of mold, but the hot alkali can be broken down.
8, poor dyeing, but the color fastness is good, not easy to fade. variety of polyester varieties of short yarns, drawn silk, deformation yarn, decorative filament, industrial filament and a variety of differentiated yarn.
