Problems solved by technology

However, due to the influence of technology and materials, most of the existing common heat-sealing tapes are made of dense adhesive film and base cloth, which are airtight and non-hygroscopic. After bonding with the fabric, the clothing fabric itself is reduced. The moisture permeability of the tape, if the tape has a breathable effect, the thickness of the surface layer must be reduced to form micropores, but this will lead to a decrease in the waterproof and adhesive properties of the heat-sealing tape

Abstract

The invention discloses a TPU adhesive layer used for heat-sealing tapes, a three-layer heat-sealing tape comprising the TPU adhesive layer and a preparation method and application thereof. The waterproof and moisture-permeable three-layer heat-sealing tape includes a base cloth, a covering The waterproof film layer on the base fabric and the TPU adhesive layer covering the waterproof film layer, the base fabric is mesh cloth, four-way stretch cloth, chiffon cloth or Oxford cloth, and the waterproof film layer is polyurethane film and polytetrafluoroethylene film The TPU adhesive layer includes the following raw materials in parts by weight: 70-95 parts of hydrophilic TPU particles, 0-15 parts of modified polyester, 0.1-1 part of antioxidant, 0.1-1 part of ultraviolet absorber 1 part, 1-10 parts of inorganic silicon compound and 0.5-3 parts of coupling agent. It has excellent moisture permeability, adhesion, water resistance, and washability, and can be widely used in waterproof products such as jackets, ski jackets, cold-proof clothing, mountaineering clothing, diving suits, and sportswear.

Description

technical field [0001] The invention belongs to the field of polymer adhesives, and in particular relates to a TPU adhesive layer used for heat-sealing tapes, a waterproof and moisture-permeable three-layer heat-sealing tape including the TPU adhesive layer, a preparation method and application thereof. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the functionality of textile clothing. Among them, the waterproof and moisture-permeable function, as an important function of outdoor sportswear, has been concerned and researched by more and more manufacturers and manufacturers, such as Patents CN108454181A, CN106087454A, CN104742480A, etc. all disclose some methods for preparing waterproof and moisture-permeable fabrics, but there is a common problem of not having both moisture-permeability and waterproofness. [0003] Heat-sealing tape is a kind of waterproof tape that is heated by a gluing machine or a h...
