there are generally two weaving methods for warp knitted fabrics: one is to use two sets of warp yarns (ground warp and skein), which are twisted to form a shed, which is interwoven with the weft yarn (see leno organization). the warp warp is twisted to the left side of the ground warp by using a special warp heddle (also known as half heddle). after one (or three, or five) weft throws, the warp is twisted to the right side of the ground warp. the mesh-shaped holes formed by the interweaving of the skein and the weft have a stable structure and are called leno; the other is to use the jacquard weave or the change of the reed method. the warp yarns are grouped by three and can be woven into a reed tooth. a fabric with small holes on the cloth surface, but the mesh structure is unstable and easy to move, so it is also called a fake leno t-shirt.
