Efficiency Textile Bonding Guide: Core Differences Between Solvent-Based and PUR Reactive Hot Melt Adhesives

Jun 20, 2025

Adhesives for textile bonding are commonly used in the production of various garments and related products. For example, functional apparel designed to provide water resistance and windproofing requires adhesives for lamination, ensuring the clothing features good windproof, waterproof, and breathability functions. Similarly, outdoor gear such as tents and sleeping bags use laminating layers bonded with adhesives to enhance waterproofness and weather resistance. The main options are solvent-based adhesives (like solvent-type and dye adhesives) and PUR reactive hot melt adhesives, each with its own advantages and disadvantages in physical performance and environmental impact.

	Solvent adhesives	PUR Hot melt adhesive
Strength and durability	Solvent adhesives provide strong, quick bonds for thick layers and various fabrics, supporting high loads. However, their durability can decline over time with water exposure, friction, or outdoor use due to aging or cracking.	PUR hot melt adhesives also exhibit very strong bonding strength, especially with soft or highly elastic fibers. They demonstrate better toughness and washability, maintaining stable adhesion even after repeated laundering over time.
Elasticity and flexibility	Solvent adhesives tend to have lower elasticity; once cured, they become more rigid, which can lead to cracks or delamination during prolonged stretching or bending.	PUR hot melt adhesives cure to a state with good elasticity and flexibility, allowing them to adapt with fabric deformation and significantly reducing the risk of cracking and loosening.
Application performance	Solvent adhesives cure faster and are easier to operate, but require proper ventilation and strict control of drying times, with somewhat higher process demands.	PUR hot melt adhesives need heating to melt, curing quickly, with high bonding efficiency. They are very suitable for high-production and high-quality textile lamination.
Environmental and health considerations	Solvent adhesives release volatile organic compounds (VOCs) during curing, which pose certain risks to operators and the environment. Regulations are increasingly restricting their use.	PUR hot melt adhesives are low-VOC products; after curing, they emit no harmful gases, making them more environmentally friendly and safer, aligning with modern green manufacturing standards.

In contemporary apparel and outdoor sports equipment, enhancing weather resistance, waterproofness, wind proofing, and bonding strength requires reliable adhesives. PUR reactive hot melt adhesives offer stable bonding performance and good elasticity, reducing maintenance and replacement costs while meeting eco-friendly trends, helping to develop healthier, greener apparel and outdoor gear industries.
