What is Hot melt silk

August 21,2023

Hot melt silk, also known as low-melting fiber, is one of the most rapidly developing functional fibers this year.

The hot melt silk is divided into two kinds of polyester hot melt silk and nylon hot melt silk,  which can control the melting point between 85 ° C and 180 ° C by adjusting the raw material characteristics.

In the normal temperature state, the hot melt silk and other fibers are woven into the fabric, and then in the dry heat or wet heat state, the pressure is applied to the fabric, when the temperature is higher than the melting point of the hot melt silk, the hot melt silk gradually melts. At this temperature, conventional fibers remain unchanged and are bonded together by the hot melt silk. Therefore, the hot melt silk can replace glue and other chemical adhesives, avoid the pollution of volatile matter and powder layer, environmental protection and non-toxic; At the same time, it saves the process flow and reduces the downstream production cost.

At present, hot melt silk is widely used in outdoor sports shoes, casual shoe upper, sofa fabric, curtain curtain, carbon fiber fabric styling, chenille yarn, bondi line, high-grade suit lining, lace lace and glove overlock yarn and other fields, is a high salary technical products with great market prospects.

Hot melt silk is divided into polyester hot melt silk and nylon hot melt silk. By adjusting the characteristics of the raw material, the melting point can be controlled between 85 and 180 ° C, the hot melt silk and other fibers are made into fabrics at room temperature, and then the pressure is applied to the fabric under dry heat or wet heat conditions. When the temperature is higher than the melting point of the hot melt silk, the hot melt silk gradually melts.

At this temperature, other conventional fibers remain unchanged and are bonded together by hot melt silks. Therefore, hot melt silk can replace glue and other chemical adhesives, avoid volatiles and powder layer pollution, environmental protection and non-toxic, save process flow, reduce downstream production costs.
Application of hot melt silk

At present, polyester hot melt silk is widely used in outdoor sports shoe upper, casual shoe upper, sand release, curtain and curtain screen, carbon fiber fabric surface styling, chenille yarn, knitted collar, ribbon, bondi line, suit lining, badminton racket string, tennis racket string, pants mouton paste and other fields, is a high-tech product with broad market prospects.
