Application of PUR hot melt adhesive in textile materials
With the widespread application of functional fabrics and composite materials in clothing, home furnishings, automotive interiors, medical and industrial fields, traditional sewing and gluing processes have been unable to meet the requirements of high performance, high efficiency and environmental protection. Polyurethane reactive hot melt adhesive (PUR) is gradually becoming an ideal solution for textile material lamination and bonding due to its excellent bonding performance, flexibility and environmental protection characteristics.
The reason why PUR hot melt adhesive (polyurethane reactive hot melt adhesive) is widely used in the textile industry is mainly due to its advantages in bonding performance, flexibility, environmental protection and durability. The following are several key reasons for the application of PUR hot melt adhesive in the textile industry:
1. Excellent bonding strength
PUR hot melt adhesive can firmly bond with a variety of textile materials (such as polyester, nylon, spandex, etc.) as well as composite materials such as membranes, non-woven fabrics, and foams. The surface of textiles is usually porous and soft, and the bonding properties of PUR can effectively penetrate into the fiber structure to form a strong bonding layer, ensuring the firm bonding of various materials.
2. Softness and elasticity
The bonding layer formed after the curing of PUR hot melt adhesive has good flexibility and elasticity, which can adapt to the stretching and deformation of textiles during use. It is particularly suitable for fabrics with high requirements for softness and comfort, such as sportswear, elastic clothing and underwear. This flexibility also allows PUR adhesive to provide effective bonding without affecting the feel and comfort of the fabric itself.
3. Washability and dry cleaning resistance
PUR hot melt adhesive has excellent washability and dry cleaning resistance, and can withstand multiple washing or dry cleaning after curing. This property makes PUR particularly good in applications that require frequent cleaning, such as clothing, home textiles, and medical protective products, such as the bonding of waterproof and breathable fabrics and the manufacture of medical protective clothing.
4. Solvent-free and environmentally friendly
PUR hot melt adhesive is a 100% solid content hot melt adhesive that does not contain solvents or formaldehyde, so it does not release harmful gases (such as VOCs) and meets strict environmental standards. This makes PUR particularly suitable for use in areas with high environmental requirements, such as baby products, medical protective materials, and export products, ensuring the safety and environmental protection of the products.
5. Efficient and automated production
The rapid curing characteristics of PUR hot melt adhesive make it very suitable for use in automated production lines. The compounding of textiles with other materials usually requires an efficient and continuous process, while PUR's rapid initial adhesion and excellent curing ensure the smooth operation of automated equipment, improve production efficiency, and adapt to the large-scale and efficient processing needs of modern industry.
6. Good adaptability
PUR hot melt adhesive can adapt to different types of textiles and their surface treatment needs. Whether it is ordinary fabric or functional membrane material, PUR can provide stable bonding effect. In addition, PUR can work stably in different temperature and humidity environments, which increases its applicability in various climates and working environments.
