There are two general methods of weaving warp-knitted fabrics: one is to use two sets of warp yarns (ground warp and twisted warp), which are twisted to form a bobbin mouth and interwoven with the weft yarn (see leno organization). The twisted warp is the use of a special twisted heddle (also known as half heddle) from time to time twisted on the left side of the ground warp, after a (or three, or five) casting, twisted to the right side of the ground warp, due to the intertwining of mutual twisting and weft intertwined with the formation of a mesh-shaped holes, the structure of the stable, known as the sarong; the other is the use of jacquard organization or changes in the method of wearing reeds, warp yarns to three as a group, wear a reed into the teeth, but also weave fabrics with holes on the surface of the fabric. fabric, but the mesh structure is not stable, easy to move, so it is also known as fake leno cultural shirts.
