Garment Polyester Hot Melting Yarn

Polyester hot-melt yarn is mixed with conventional polyester or other fibers to produce non-woven fabrics or knitted or woven into thermally bonded fiber products, which have the characteristics of soft hand feeling, high strength, washing resistance, crispness, easy care, and no environmental pollution.

Application of polyester hot melt yarn:

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 hot melt yarn:

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. 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 better among synthetic fibers.

4. Good thermoplasticity and poor melting resistance. Because polyester has a smooth surface and tightly arranged internal molecules, polyester is a fabric with relatively good heat resistance among synthetic fabrics. It is thermoplastic and can be made into pleated skirts. At the same time, polyester fabrics have poor melting resistance and are prone to forming holes in the presence of soot and sparks. Therefore, try to avoid contact with cigarette butts, sparks, etc. when wearing.

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