Description

Technical Field

[0001] The utility model relates to a polyester stretch yarn hot-melt device, belonging to the field of polyester stretch yarn hot-melt. Background Art

[0002] Polyester stretch yarn hot melt, also known as polyester hot melt yarn or low-melting-point fiber, is a special functional fiber characterized by its ability to melt and flow at high temperatures, then solidify into a solid state upon cooling, thereby bonding to other materials. This fiber is widely used in textiles, clothing, packaging, automotive interiors, and other industrial fields, primarily as an adhesive or reinforcement. In the prior art, during the polyester stretch yarn hot melt process, one end of the polyester stretch yarn contacts the surface of a heated roller. The heating wire inside the roller heats the roller surface to the polyester stretch yarn's melting point. However, during the contact and hot melt of the polyester stretch yarn, the melted polyester stretch yarn tends to remain on the roller. This residue can affect the thermal conductivity of the roller when the next batch of polyester stretch yarn is hot melted, slowing down the hot melt speed of the strands. Therefore, a polyester stretch yarn hot melt device is needed that can reduce the amount of melted polyester stretch yarn remaining on the roller. Utility Model Content
