Polyester Thermal Fuse

Polyester thermal fuse is widely used in flying shoe uppers, chenille yarns, high-end linings, trousers, knitted hats, Bondi threads, socks and shoes.

Thermal fuse, also known as low melting point fiber, is one of the functional fibers that has developed rapidly in recent years.

Thermal fuse is divided into polyester thermal fuse and nylon thermal fuse. The melting point can be controlled between 85C and 180°C by adjusting the characteristics of raw materials.

At room temperature, the thermal fuse is woven with other fibers to form a fabric, and then under dry heat or moist heat, pressure is applied to the fabric. When the temperature is higher than the melting point of the thermal fuse, the thermal fuse gradually melts. At this temperature, other conventional fibers remain unchanged and are bonded together by thermal fuse.

Application of Polyester thermal fuse:

It is mainly used for thermal bonding and is used in industries such as Bondi thread weaving, high-strength webbing, wool carpets, cushions, and automobile inner linings.

Features of Polyester thermal fuse:

1. high strength. 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 is not wrinkled 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 strong and durable.

3. Good abrasion resistance. The abrasion resistance is second only to nylon with better abrasion resistance, better than other natural fibers and synthetic fibers.
