What is hot melt yarn and how is it made

Hot melt yarn is a type of synthetic yarn that has a low melting point and can be used to bond fabrics together without the need for additional adhesives or stitching. It is often used in the production of apparel, shoes, bags, and other textile products.

Hot melt yarn is typically made by melting a thermoplastic resin, such as polyester or nylon, and extruding it through a spinneret to create a fine filament. The filament is then stretched and cooled to create a continuous yarn. Depending on the desired properties and performance of the yarn, various additives or modifiers may be added to the resin prior to extrusion.

 

The melting point of hot melt yarn is carefully controlled during the manufacturing process, as this determines the temperature at which the yarn will bond with other fabrics. When the yarn is heated to its melting point, it becomes soft and pliable, allowing it to fuse with other fabrics. As the yarn cools and solidifies, it forms a strong bond with the fabric, creating a durable and long-lasting bond.

 

Hot melt yarn can be produced in a range of thicknesses, colors, and textures to meet the specific needs of different applications. It is a versatile and cost-effective alternative to traditional sewing or adhesive methods, offering greater efficiency, flexibility, and durability in textile manufacturing processes.
