2. Introduction of hot melt adhesive: Hot melt adhesive (English name: Hot Glue) is a plastic adhesive. In a certain temperature range, its physical state changes with the change of temperature, while its chemical characteristics remain unchanged. Non-toxic and tasteless, it is an environmentally friendly chemical product. Because the product itself is solid, it is convenient for packaging, transportation and storage, without solvent, pollution and toxicity; And has the advantages of simple production process, high added value, high bonding strength and high speed.

Step 3 use:

Hot melt adhesive is the most widely used adhesive in textiles, especially in garment processing, which is widely used to bond non-woven fabrics, carpet seams, garment linings, zippers and so on. Hot melt adhesive for textile industry should have good bonding strength, excellent softness and water/dry cleaning resistance. In addition, because most fabrics are treated by steam in the setting process, it is required that the adhesive has the characteristics of high temperature steam resistance, its softening point is higher than 1 15℃, and appropriate crystallinity is required to improve the thermal stability of the adhesive. For example, the lower limit of polyamide content is 45% (mass fraction). For fiber fabrics with excellent softness, hot melt adhesive is required to have low processing viscosity.
