Description

A TPU warp knitted fabric

Technical Field

The utility model belongs to the technical field of textile weaving, and particularly relates to a TPU warp knitted fabric.

Background technique

Warp knitted fabrics are classified into two types: single-sided and double-sided. Single-sided warp knitted fabrics are woven in a single-needle bed warp knitting machine. One side of the fabric is composed of coils, while the other side is distributed with the extension lines of the coils. Double-sided warp knitted fabrics are woven in a double-needle bed warp knitting machine. Both sides of the fabric are composed of coils, and the extension lines of the coils are in the coils on both sides. There are many kinds of warp knitted fabrics, which can be used as underwear, outerwear, curtains, lace, etc. Jacquard mesh is a type of warp knitted jacquard mesh. It usually uses the offset of jacquard needles to form thick tissues, thin tissues, mesh tissues, and the combination of the above tissues on the fabric. It has a richer variety of patterns. The warp knitted fabrics woven using jacquard warp knitting technology have multiple patterns, multiple colors, and multiple layers, which are widely welcomed by the market. It has become a trend to carry out in-depth development of functional superposition based on jacquard mesh.

TPU is a thermoplastic elastomer material. Due to its good and full elastic feel and good natural water-repellent function, most of the warp knitted meshes woven by warp knitting machines are ordinary warp knitted meshes, which have greater elasticity and the fabric is easily pilled or hooked out by friction, forming silk loops, affecting the appearance.

Therefore, it is necessary to design a novel TPU warp knitted fabric and a knitting method thereof to solve the above-mentioned technical problems.
