22s Elastic Weft Yarn, used for polyester tire cord fabric and tire cord fabric, it has a two-component coating structure, with nylon 66 yarn as the inner core and long-staple cotton coating and twisted as the outer layer. This structure has increased the initial modulus during weaving and prevented the accidental elongation of nylon 66 yarn; followed by increased friction to prevent the slippage of nylon 66 yarn and ensure the stability of cord fabric forming.
