Polyester sewing thread is known for its durability, strength and wear resistance.
Some of the advantages of using polyester yarn include:
1. High strength. The short fiber strength is 2.6 ~ 5.7cN/tex, and the high fiber strength is 5.6 ~ 8.0cN/tex. Due to its low moisture absorption, its wet strength and dry strength are basically the same. The impact strength is 4 times higher than polyamide and 20 times higher than viscose fiber.
2. Good flexibility. The elasticity is close to wool, and the extension of 5 to 6 times can almost be completely restored. Wrinkle resistance is better than other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The elastic modulus is 22 ~ 141cN/.
3. Heat-resistant polyester is made by melt spinning, and the fiber after molding can be reheated and melted, which is a thermoplastic fiber. The melting point of polyester is relatively high, the specific heat capacity and thermal conductivity are small, so the heat resistance and heat insulation of polyester fiber are high. This is the best synthetic fiber.
4. Good wear resistance. The wear resistance is second only to the good wear resistance of nylon, better than other fibers and synthetic fibers.
5. Good light resistance. Light resistance is second only to acrylic fiber. Polyester fabric has better light resistance, in addition to worse than acrylic fiber, its sun resistance is better than fiber fabric. Especially in the glass behind the sun resistance is very good, almost equal to acrylic fiber.
