[0002] Sandwich mesh is a double needle bed warp knitted mesh, consisting of a mesh surface, connecting monofilaments, and a flat cloth bottom. Because of its three-dimensional mesh structure, it looks like a Western sandwich hamburger, so it is named sandwich mesh. Usually, the upper and lower surfaces are made of polyester, and the middle connecting thread is polyester monofilament. The thickness is generally two to four millimeters. It is widely used in car seat covers, luggage and shoes, roller skates, bedding and other fields.
