polyester Red FDY features
1.Good thermoplasticity, poor melting resistance. Because of its smooth surface and close arrangement of molecules, polyester is one of the most heat-resistant fabrics in synthetic fabrics. It is thermoplastic and can be made into pleated skirts with long-lasting pleats. At the same time, polyester fabric has poor fusing resistance, and it is easy to form holes when encountering soot and sparks. Therefore, when wearing should try to avoid contact with cigarette butts, sparks, etc. Polyester filament
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.
