Problems solved by technology

At present, although the TPU hot-melt adhesive film on the market has a certain degree of elasticity and bonding strength, it still performs poorly in sportswear and underwear that require high elasticity, mainly due to low adhesion and poor washability. Poor, low tensile strength, large tensile deformation, etc.
Especially applied to the bottoms of seamless sports pants, bras, and side bones of sportswear, which affects the comfort of seamless sportswear, shortens the service life, and cannot improve the quality and appearance of clothing

Abstract

The invention relates to the field of polymer adhesives, in particular to a TPU adhesive, a hot-melt adhesive film and its application. The TPU adhesive of the present invention comprises the following components by weight: 75-97 parts of TPU particles; 0-15 parts of modified polyester; 2-10 parts of anti-hydrolysis agent; 0.1-1 part of auxiliary agent. The hot-melt adhesive film of the present invention comprises a first adhesive layer, a substrate layer, and a second adhesive layer in sequence; the first adhesive layer is made of the above-mentioned TPU adhesive, and the second adhesive layer is made of the above-mentioned TPU adhesive Made; the base layer is mesh or film. The hot-melt adhesive film with a three-layer composite structure of the present invention is soft to the touch, has high tensile strength, excellent stretch recovery, good adhesion and washability, and can be widely used in underwear, underwear, and bras , mold cups, shoulder straps, shapewear, sportswear and other elastic clothing seamless bonding.

Description

Technical field [0001] The present invention relates to the field of polymer adhesive, particularly a hot melt adhesive film and the application of TPU. Background technique [0002] Polyurethane is a developmental rapid multifunctional polymer composite material, since the adjustability of the molecular structure and diverse variety of raw materials, and may be made of foams, elastomers, coatings, adhesives and other products in the form of extremely versatile . Similarly, by adjusting the raw materials and formulations can be designed for a variety of adhesive between the materials, a variety of different uses of a plurality of types of polyurethane adhesives. Polyurethane adhesive having excellent flexibility, impact resistance, chemical resistance, and particularly excellent low-temperature resistance and abrasion resistance. [0003] With the development of science and technology, knitwear has become increasingly broad market. In the conventional processing method, a knitted...
