Polyester thermal fuse is produced by spinning low-melting polyester chips. Low-melting polyester chip is a modified polyester prepared by adding third and fourth modified monomers to conventional polyester. Compared with polypropylene and polyamide fibers, polyester thermal fuses will flow and deform after melting, and cannot be restored to their original shape after cooling, so the thermal shrinkage is very large, while the thermal shrinkage of low-melting fibers in their free state is only 5%.

Polyester thermal fuse has many features:

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

2. Good elasticity. The elasticity is close to that of wool, and it can almost fully recover when the elongation is 5% to 6%. The wrinkle resistance exceeds other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The elastic modulus is 22~141cN/dtex, which is 2~3 times higher than that of nylon. .Polyester fabric has high strength and elastic recovery ability, so it is strong and durable, wrinkle-resistant and iron-free.

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

4. Good thermoplasticity and poor melting resistance. Due to the smooth surface of polyester and the close arrangement of internal molecules, polyester is the most heat-resistant fabric in synthetic fabrics. It has thermoplastic properties and can be made into pleated skirts with long-lasting pleats. At the same time, polyester fabric has poor melting resistance, and it is easy to form holes when encountering soot, sparks, etc. Therefore, try to avoid contact with cigarette butts, sparks, etc. when wearing.

5. Good abrasion resistance. The abrasion resistance is second only to the nylon with the best abrasion resistance, and it is better than other natural fibers and synthetic fibers.
