Compared with weft knitted fabrics, warp knitted fabrics generally have less extensibility. Most weft knitted fabrics have significant transverse elongation. The extensibility of warp knitted fabric is related to the number of comb bars and structure. Some warp knitted fabrics have lateral and longitudinal extensibility, but some fabrics have good dimensional stability. Warp knitted fabrics can use different structures to reduce the coil separation defects caused by yarn breakage and holes like weft knitted fabrics. In addition, warp knitted fabrics can use yarns of different thicknesses for different weft lining weaving, form different forms of mesh organization and simple pattern transformation, so almost all fabric organizations can be woven.

Warp knitted fabric has certain elongation and stretch. Warp knitted fabric can use high-strength fiber yarn, yarn with balanced structure, high machine number and fine high-strength yarn. In addition, the strength of the fabric will be affected by the use of strands combined with different fiber yarns and the change of coil spacing.

1. Polyester warp knitted fabric has high strength. The short fiber strength is 2.6 ~ 5.7cn/dtex, and the high strength fiber is 5.6 ~ 8.0cn/dtex. Because of its low hygroscopicity, its wet strength is basically the same as its dry strength. The impact strength is 4 times higher than that of nylon and 20 times higher than that of viscose fiber.

2. Heat resistance of polyester warp knitted fabric polyester is made by melt spinning, and the dimension of the formed fiber is heated and melted again. It belongs to thermoplastic fiber. The melting point of polyester fiber is relatively high, but the specific thermal void and thermal conductivity are small, so the dimensional heat resistance and absolute heat resistance of polyester fiber are higher. It is the best of synthetic fibers.

3. Good wear resistance. The wear resistance is second only to the best nylon, which is better than other natural fibers and synthetic fibers.
