Regular hot melt adhesive powder materials are TPU, co-polyamide, co-polyester and EVA, the main advantage of the adhesive powder is its powder form, so adhesive powder can be directly dispersed on the surface of the substrate by a powder spreader, and the bonding process can be completed in a short time by heating and pressing, or finished by baking, no need to heat and melt into liquid before use.
With the gradual improvement of people's requirements for the quality of life, thermal bonding technology in the textile industry has become a trend to replace traditional stitching, and features such as seamless technology, waterproofing, hot pressing technology, water resistance, and dry wash resistance have attracted more and more attention. The hot melt adhesive with matching performance is very important to ensure the realization of various requirements, so hot melt adhesive has become an indispensable auxiliary material for clothing production.
As an emerging material in recent years, hot melt adhesive has the characteristics of convenient use, environmental protection and non-toxicity, which can replace the traditional sewing process. Therefore, in recent years, hot melt adhesives are increasingly used in the field of clothing. This article will introduce hot melt adhesives commonly used in clothing through the two dimensions of material and form.
