Liners include cotton cloth lining, hemp lining, animal wool lining and chemical lining.

Cotton cloth lining can be divided into coarse cloth and fine cloth. Coarse cloth belongs to cotton coarse plain cloth, which has rough appearance, cotton impurities, solid cloth body and poor quality. It is usually used to make large body linings, shoulder linings and chest linings. Fine cloth belongs to cotton fine plain cloth, and its appearance is fine and clean. Fine cloth lining is divided into two types: self-lining and bleaching lining. This self-lining is usually used as collar lining, cuff lining, right back lining, tie belt, etc. Bleached lining is used as barge head lining and lower foot lining.

There are two kinds of linen lining: linen lining and rubber lining on flat cloth. Linen belongs to linen fabric arranged in plain weave, which has good elasticity and can be used as various linings for various woolen garments and coats. The gluing lining of plain cloth is a plain fabric blended with cotton and hemp, and is glued. It is crisp and smooth, with good elasticity and flexibility, moderate softness, but large shrinkage rate, so it should be used after pre-shrinking. Rubber lining on plain cloth is mainly used to manufacture medium and thick clothing, such as Chinese tunic suit and suit.

Knitting skills include weaving, knitting, knitting and non-knitting, among which knitting is divided into warp knitting and weft knitting. The orientation of warp knitting in weaving is shown in the following figure, which is a textile skill in the field of knitting. A knitted fabric is formed by looping one or several groups of yarns placed in parallel on all working needles of the warp feeding machine. This method is called warp knitting, and the knitted fabric formed is called warp knitted fabric.

Knitting is a way to form fabrics, and the fabrics it forms are called knitted fabrics. Knitted fabrics are made by looping each other. Knitted fabrics can be divided into warp knitted fabrics and weft knitted fabrics according to the looping direction of yarns in fabrics. The titles of warp knitting and weft knitting come from weaving. Weaving is the most worn-out textile skill. Woven fabric is formed by interlacing longitudinal warp yarns and transverse weft yarns. In warp knitted fabric, the same yarn forms loops along the warp direction (longitudinal direction) of the fabric; In weft knitted fabrics, the same yarn forms loops along the weft direction (transverse direction) of the fabric. Only one yarn (or a limited number of yarns) is needed to form weft knitted fabrics, while one or several groups of yarns are needed to form warp knitted fabrics, and each group of yarns is composed of many yarns.
