Warp-knitted mesh fabric with gradually-changed meshes

Abstract

The warp knitting mesh fabric comprises a surface layer, a middle layer and a bottom layer, and the middle layer is a supporting layer and is connected with the surface layer and the bottom layer; the surface layer is of a mesh cloth structure which is gradually changed from small meshes to large meshes and then gradually changed from the large meshes to the small meshes, and the mesh cloth structure is periodically and cyclically changed. According to the warp knitting mesh fabric with the gradually-changed meshes, the feeling that the large mesh areas protrude out of the surface layer and the small mesh areas are sunken in the surface layer is brought to people, the stereoscopic impression is high, and the fabric is good in breathability and rebound resilience and meanwhile the attractiveness is improved.
