There are three weaving methods of woven mesh :(1) with the change of jacquard structure or reed method, the warp yarn is arranged in groups of three and penetrated into a single sley, but the mesh is easy to move and the structure is unstable, so it is also called false gauze; (2) two sets of warp yarns (ground warp and twisted warp) are used to twist and twist each other to form a shed and interweave with the weft yarns (see leno structure). Among them, twisted warp is a special twisted heddle (also known as half heddle) sometimes twisted twisted in the left side of the warp, after one or five weft insertion, twisted twisted to the right side of the warp, because twisted and weft interweave the formation of mesh holes, stable structure, known as leno;
