Details

Adhesive lining is a type of lining coated with hot melt adhesive, which is one of the commonly used auxiliary materials in fabric production. The adhesive lining is attached to the back of the fabric through heating and pressing. When the fabric needs to express its firmness and thickness, it can be reflected by adding an adhesive lining, or when the fabric is too soft and slippery to operate, adding an adhesive lining can make the fabric obedient and obedient~~

Non woven adhesive lining

Non woven adhesive lining is made of non-woven fabric (non-woven fabric) as the base fabric, which has an advantage in price compared to fabric adhesive lining, But the quality is undoubtedly slightly inferior. Non woven lining is suitable for some edge and corner positions, such as opening bags, locking buttonholes, and so on. Non woven linings also have thickness differences, and their thickness will be directly reflected in the position used, which can be selected according to needs

Fabric bonding

Fabric bonding lining is made of knitted or woven fabric as the base fabric, with the most commonly used being woven fabric.

. Fabric adhesive lining is often used for the main body or important position of the work, and there are also soft and hard fabric adhesive lining, which needs to be selected according to the situation

Double sided adhesive

The common double-sided adhesive lining is as thin as cicada wings, and it is more suitable to use adhesive instead of lining.

. It is usually used to bond and fix two pieces of cloth, for example, when pasting the cloth, it can be used to stick the cloth to the background cloth, which is very convenient to operate. There are also double-sided adhesive linings in the market that are rolled in strips, which are very useful when folding or rolling
