What kind of fabric is polyester?

Advantage:
1. High toughness. The short fiber strength is 2.6～5.7cN/dtex, and the high tenacity fiber is 5.6～8.0cN/dtex. Due to its low hygroscopicity, its wet strength and dry strength are basically the same. The impact strength is 4 times higher than nylon and 20 times higher than viscose fiber.

2. Good flexibility. The elasticity is close to that of wool, and it can almost completely recover when it stretches 5% to 6%. The wrinkle resistance is better than other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The modulus of elasticity is 22～141cN/dtex, which is 2～3 times higher than nylon. .Polyester fabric has high strength and elastic recovery ability, so it is durable, anti-wrinkle and non-ironing.

3. Heat-resistant polyester is made by melt spinning, and the formed fiber can be heated and melted again, which is a thermoplastic fiber. The melting point of polyester is relatively high, but the specific heat capacity and thermal conductivity are small, so the heat resistance and thermal insulation of polyester fiber are higher. It is the best among synthetic fibers.

4. Good thermoplasticity and poor melting resistance. Because polyester has a smooth surface and tightly arranged internal molecules, polyester is the most heat-resistant fabric among synthetic fabrics. It is thermoplastic and can be made into pleated skirts with long-lasting pleats.
