Polyester Elastic Weft Yarn for Radial Tire Cord Fabric

Specifications:

18S, 20S, 22S, 26S.

The Polyester elastic weft yarn adopts a bicomponent wrapped structure, with polyester filament FDY as the core and long-staple cotton wrapped around the outer layer before twisting. It boasts excellent properties such as high initial tensile strength, high breaking elongation after full dipping, and good heat resistance. During the fabric dipping and heat treatment process, the fiber experiences minimal loss of strength and extensibility, maintaining the fabric structure stability, and exhibits outstanding thermal stability and resistance to mechanical deformation.

Features:

• Bicomponent wrapped structure: With polyester filament as the core and long-staple cotton as the outer wrapping, it features high initial tensile strength and excellent heat resistance.
• Excellent transverse elasticity: High weft elongation enables it ideal for garments requiring lateral mobility, delivering superior comfort and unrestricted freedom of movement.
• Good tensile stability after dipping: It maintains uniform expansion of the cord fabric during tire building and vulcanization processes.
• Enhanced friction: The outer wrapping boosts friction to prevent core slippage and ensure fabric structural stability.
