High strength.
The short fiber strength is 2.6 ~ 5.7cN/dtex, and the high strength fiber is 5.6 ~ 8.0cN/dtex.
Due to its low hygroscopic properties, its wet strength is basically the same as its dry strength.
The impact strength is 4 times higher than polyamide and 20 times higher than viscose fiber.
Good elasticity.
The elasticity is close to wool, and when it is extended by 5% to 6%, it can be almost completely restored.
Wrinkle resistance is more than other fibers, that is, the fabric does not wrinkle, and the dimensional stability is good.
The elastic modulus is 22 ~ 141cN/dtex, which is 2 ~ 3 times higher than polyamide fiber.
Polyester fabric has high strength and elastic resilience, so it is fast, durable, wrinkle-resistant and ironing.
