Application of TPU hot melt adhesive film in the production of seamless underwear

TPU hot melt adhesive membrane plays an important role in the production of seamless underwear. It is a mesh adhesive film made of thermoplastic polyurethane. It has excellent elasticity, softness and bonding properties. It can achieve strong bonding between fabrics under heating and pressure conditions, thereby replacing traditional sewing processes and achieving a truly seamless effect.

In terms of specific applications, it is first reflected in the bonding of side seams and splicing parts. The seams at the side seams of traditional underwear can easily cause friction and discomfort, but after being hot-pressed and bonded with hot-melt adhesive membrane, the seams are smooth and compliant, leaving no traces or pressure when worn, greatly improving comfort. Secondly, at the joints between the edge of the cup, the bowl ring, the shoulder straps and the body, the omentum can provide long-lasting adhesion, and it can still maintain a good fit after being washed many times, and it is not easy to peel off or delaminate. In addition, the lamination of lace, decorative accessories and main fabrics is often completed with the help of mesh. After bonding, the edges are delicate and natural, and will not affect the original feel and breathability of the fabric.

From a technological perspective, the omentum is easy to use. You only need to place it between two layers of fabrics and press them together at a suitable temperature using hot pressing equipment. The operation is simple and efficient, and is suitable for large-scale continuous production. At the same time, the TPU material itself is environmentally friendly and non-toxic, and meets the safety requirements for underwear to be worn close to the body. Its elasticity can keep pace with the expansion and contraction of the fabric without restricting the expansion of clothing, ensuring the fit and stability of seamless underwear during sports and daily wear.

Taken together, TPU hot-melt adhesive membrane has become an indispensable key auxiliary material in the production of seamless underwear due to its many advantages such as softness and tracelessness, washability and durability, green environmental protection and efficient processing, driving the underwear industry to continuously develop in the direction of comfort, functionality and quality.
