Multilayer mesh structure

Abstract

A multilayer mesh structure has multiple mesh layers being stacked on each other, and may have a woven sheet and a covering layer. Each mesh has multiple primary and secondary fibers. The secondary fibers are mounted crossing over and connecting to the primary fibers at multiple bonded intersections to form the mesh. The woven sheet is formed on a surface of the mesh and may be a natural or man-made fiber (such as rayon, nylon cotton or linen fibers) woven sheet. The covering layer is a film material to enclose and hold the multiple mesh layers. When the multilayer mesh structure is used as a shoe-pad or the like, the multilayer mesh structure provides a shoe with the shoe-pad better air permeability and elasticity.
