Definition: High-elastic polyester yarn is a polyester yarn with significant elastic properties made by a special process.
Characteristics:
High elasticity: This yarn has excellent elasticity and recovery, and can quickly return to its original shape after being subjected to external force.
Durability: Polyester fiber itself has high wear resistance and wrinkle resistance, so that this yarn can still maintain good appearance and performance in long-term use.
Easy to process: Polyester fiber is easy to spin and process, and can meet the needs of different textile processes.
Diversity: It can be customized according to customer needs, such as color, thickness, elasticity, etc.
The manufacturing technology of high-elastic polyester fiber yarn is diverse, including but not limited to the following:
Traditional DT, DTY method: Through stretching, twisting and other processes, the fiber is curled and elastic.
Asymmetric (uneven) processing method: The asymmetry of the fiber during processing is used to produce permanent curling, thereby improving the elasticity of the fiber.
Asymmetric cooling molding method: By controlling the asymmetry of the fiber flow during the cooling process, the fiber has the potential for self-winding, thus giving it high elasticity.
New polyester materials: New polyester materials such as PBT (polybutylene terephthalate) and P1TI1 (polypropylene terephthalate) have higher elasticity and softness and can be used to make high-elastic polyester fiber yarns.
High-elastic polyester yarns are widely used in many fields due to their excellent elasticity and durability:
Textiles and clothing: used to make various elastic clothing and accessories, such as stretch pants, sportswear, swimsuits, etc.
Home decoration: can be used to make household items such as carpets and curtains, providing comfortable touch and visual effects.
Industrial field: In industry, high-strength and high-elastic polyester fiber yarns can be used to make high-strength and high-wear-resistant products such as tire cords and conveyor belts.
