In recent years, with the rise of the concept of green chemistry, environmentally friendly materials have gradually become the development trend of today's industrial materials. Traditional polyurethane adhesives contain organic solvents, which easily cause environmental pollution and are inconvenient to use. They are far from meeting the needs of large-scale industrial production. Moisture-hardening reactive polyurethane hot-melt adhesive (PUR) is a new type of adhesive developed on the basis of traditional hot-melt adhesives. It not only has the characteristics of good initial tack of traditional hot-melt adhesives, but also excellent curing properties of moisture-curing adhesives. It also has the advantages of changing the composition and structure of polyurethane and a wide range of performance adjustment. It has excellent adhesion to a variety of substrates.

Made of at least one of polyethylene (Linear Low Density Polyethylene, LLDPE) and polytetrafluoroethylene (Polytetrafluoroethene, PTFE). The waterproof and breathable membrane 4 has a plurality of breathable holes 41. The waterproof and breathable membrane 4 is combined with the adhesive layer 3. The breathable holes 41 can provide gas to enter and leave the accommodating space 13, and because the apertures of the breathable holes 41 are relatively small, The surface tension of the liquid will block the entry into the accommodating space 13, so the waterproof and breathable membrane 4 can prevent the liquid from entering the accommodating space, and block the hard pointed body from passing through the through hole 12.

In the preferred embodiment of the present invention, since the moisture-curing reactive polyurethane (PUR) is blocked with an isocyanate group (-NCO) reactive functional group, its chemical activity is lively, except that it can react with water and gas in the environment to generate intermolecular bridges. It can also react with active hydrogen on the substrate (such as PU film, TPU film, fabric and other materials) to bridge the reaction, producing the so-called "anchoring effect" and exhibiting excellent adhesion properties, so it can be used in textile processing technology, mainly used in textile processing technology. Cloth / cloth, film / cloth bonding, because no solvent is used in the bonding process, no drying program is needed, the speed is fast, the amount of glue is small and accurate. "Waterproof and moisture permeable" fabric emphasizes its moisture permeability, soft hand, water pressure resistance, and water washability. Therefore, a hydrophilic adhesive must be selected when the finished product is compounded to maintain the finished product's moisture permeability retention level.

At present, the moisture-curing reactive polyurethane (PUR) suitable for the application of moisture-permeable fabrics has been successfully developed. It is not only solvent-free but also has many advantages in use. The PUR produced has been widely used in textiles for fabrics / films and fabrics. The cloth fits, the finished product has the characteristics of soft touch and good adhesion. The environmental protection awareness of all walks of life has increased, and the importance of low-toxicity and low-pollution products has also increased.
