Warp knitted fabrics are divided into two categories:
One is Raschel fabric, the main feature is large flower shape, coarse cloth surface, many holes, mainly used as decorative fabric;
The second is tricot fabric, with fine cloth surface and few patterns, but high output. It is mainly used for covering fabrics and printed fabrics. This type of fabric is mostly used for chemical fiber filaments, otherwise the production efficiency is extremely low.
Synthetic filaments such as polyester, nylon, vinylon, and polypropylene are often used as raw materials, and cotton, wool, silk, linen, chemical fibers and their blended yarns are also used as raw materials for weaving. It has the advantages of good longitudinal dimensional stability, stiff fabric, low dispersibility, no curling, and good air permeability. But its lateral extension, elasticity and softness are not as good as weft knitted fabrics. There are mainly the following types:
1. Polyester warp-knitted metal knitted fabric: the fabric is flat, bright in color, thick and thin. The thin type is mainly used as metal knitted fabric for shirts and skirts; the medium and thick type can be used as men's and women's clothing, windbreakers, tops, suits, trousers and other metal knitted fabrics;
2. Warp-knitted pile fabric: mainly used as metal knitted fabric for winter coats, windbreakers, jackets, trousers, etc. The fabric has good drape, easy to wash, quick-drying, and non-ironing, but static electricity accumulates during use and is easy to absorb dust ；
3. Warp-knitted mesh fabric: The mesh fabric has a light and thin texture, good elasticity and air permeability, and a smooth and soft hand feeling. It is mainly used as a metal knitted fabric for summer shirts for men and women;
4. Warp-knitted velvet fabric: The surface is densely fluffy, it feels thick, plump, soft, flexible, and has good warmth retention. It is mainly used as winter clothing and children's metal knitted fabric;
5. Warp-knitted loop fabric: this kind of fabric has full and thick hand feeling, firm and thick cloth body, good elasticity, moisture absorption, good warmth retention, stable loop structure, and good wearing performance. It is mainly used for sportswear and lapel T-shirts. , Pajamas, children's clothing and other metal knitted fabrics.
