Woven interlining includes woven interlining and knitted interlining two categories. Knitted interlining is divided into warp knitted interlining and weft knitted interlining. Warp-knitted bonded interlining is mainly used for woolen clothing. Weft woven bonded interlining is mainly used for all wool fabrics and thin fabrics. These two interlinings can be bonded directly to the woolen fabric.

Non-woven interlining is made of viscose fiber and polyester staple fiber by chemical bonding process. Divided into thick, medium and thin three, the color is mainly white. It is light, soft, hail, shrinkage, small elasticity, because there is no warp and weft and easy to use, generally used for shirt collar lining, lining, bag mouth lining and so on. In the welt part, non-woven lining plays an auxiliary role, and can also be used for the hanging face, collar face, bag cover and bag opening part of wool clothing.
