Technical Field

The utility model relates to the field of knitted fabrics, in particular to an elastic knitted fabric.

Background

Compared with woven fabrics, the knitted fabric is formed by connecting yarns through mutually hooked loops, has better elasticity and ductility, and is commonly used for manufacturing fabrics with certain requirements on elasticity, however, because the yarns of the knitted fabric are arranged in weft directions or warp directions, the elasticity of the fabrics in two directions is difficult to consider, and the ductility of the fabrics in all directions has a larger difference.

There is therefore a need to propose a new solution to this problem.
