రంగు పాలిస్టర్ ఫిలమెంట్ FDY లక్షణాలు
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 dry strength 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. Heat-resistant polyester is made by melting spinning, and the formed fiber can be melted again by heating, which belongs to thermoplastic fiber. The melting point of polyester is relatively high, and the specific heat capacity and thermal conductivity are small, so the heat resistance and thermal insulation of polyester fiber is higher. It's the best of synthetic fibers.
