More and more garment factories use PA hot-melt adhesive film instead of needle stitching process. Some processes such as sewing and seaming of clothes need to use PA hot-melt adhesive film, replacing the traditional process. The reasons for use are as follows:

The washing resistance of PA hot melt adhesive film is related to the moisture absorption of PA. The lower the moisture absorption, the better the washing resistance of PA hot melt adhesive film. The textiles using PA hot melt adhesive film mainly include clothing, carpets and fabrics. Flocking, etc.

The traditional garment industry uses manual sewing to be particularly troublesome,Hot Melt Adhesive Film Series Suppliers and it also requires the operator to have a certain amount of garment making experience. The use of PA hot-melt adhesive film to bond the seams, laces and decorations, etc., can make the clothing fabrics always adhere to each other, and The clothing is also durable, which indirectly reduces costs and improves work efficiency.

The biggest obstacle encountered by hot melt adhesive film application and fabric bonding is the cleaning of fabrics, that is, dry and wet washing resistance and water washing fineness. Nylon and natural rubber are selected as the bonding layer materials, and a PA hot melt adhesive film suitable for clothing is trial-produced. The experimental results show that the peel strength of the PA film can reach 4.51N/cm, which exceeds the peel strength of imported samples (2.20N/cm) , PA hot-melt adhesive film has good bonding strength when contacting the cloth, and can be used for bonding the end of the zipper cloth base. Because PA hot melt adhesive film has excellent washing resistance and dry cleaning resistance, it is very popular with manufacturers.
