Background

Most of jacquard fabrics in the market at present are surface layer jacquard, i.e. jacquard patterns are displayed on the surface layer, and when the colors of the patterns are bright, the formed patterns are also bright. However, with the change of the requirements of consumers in the market on the patterns of the fabrics, the jacquard structures which are hidden and appearing are gradually favored by the consumers, the fabrics have the patterns of the jacquard fabrics, the layering sense of the fabrics is richer, and meanwhile, the patterns of the fabrics are lower due to the fact that the patterns are partially hidden, so that the fabrics are gradually applied to the fields of clothes, shoe materials and the like. At present, in order to achieve the invisible effect with invisible patterns, a composite mode is often adopted, that is, a layer of lighter and thinner fabric or a fabric with a mesh structure is compounded on the surface layer of a jacquard fabric to shield part of the patterns so as to form the invisible effect with the patterns, but in the composite mode, chemical substances such as an adhesive and the like can be used in the compounding process, so that the environment is not protected, the cost is increased, and the hand feeling of the fabric can be influenced by the use of the adhesive.

In the warp knitting jacquard technology, chinese patent CN201811131737.1 (a suspended stereoscopic transparent mesh and a manufacturing method) discloses a mesh, which is characterized in that a suspended pattern of the mesh is designed on a computer, the suspended pattern is padded and looped on front and back needle beds of a double needle bed warp knitting machine, and the parts of the surface layer and the bottom layer corresponding to the hollowed-out position or the blank position are connected by yarns to obtain the stereoscopic suspended mesh. The fabric woven actually in the patent has the texture effect position relation presented by the base part of the surface and the bottom in one-to-one correspondence, and the jacquard texture at the bottom cannot be fully presented on the surface.
