Color polyester filament FDY features
1. High strength. The strength of short fiber is 2.6 ~ 5.7cN/dtex, and that of high strength fiber is 5.6 ~ 8.0cN/dtex. Because of its low hygroscopicity, its wet strength and drystrength are basically the same. Impact strength is 4 times higher than nylon, 20 times higher than viscose fiber.
2. Good elasticity. The elasticity is close to wool, and can be almost completely recovered when the elongation is 5% ~ 6%. Crease resistance exceeds other fibers, that is, the fabric does not crease, good dimensional stability. The elastic modulus is 22 ~ 141cN/dtex, which is 2 ~ 3 times higher than nylon. Polyester fabric has high strength and elastic recovery ability, therefore, it is durable, wrinkle resistant and ironing free.
3.Corrosion resistance. Resistant to bleach, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Resistant to dilute alkali, not afraid of mildew, but hot alkali can make it decompose. There are strong acid and alkaline resistance, anti - ultraviolet ability
