Heat-melt nylon fiber is a special type of nylon fiber that can melt and bond with other materials when heated. This fiber is typically made from low-melting polyamide (nylon) or polyester, and its melting point can be controlled between 85°C and 180°C by adjusting the characteristics of the raw material. Compared to ordinary fibers, heat-melt nylon fiber melts at a much lower temperature, allowing it to achieve the desired adhesion without damaging the fibers or fabrics. It enhances the cohesion of the fibers and imparts shape stability.
The typical applications of heat-melt nylon fiber include textiles, footwear, industrial products, etc. It can be used to make high-strength Bondi threads, innovative fibers for high-grade knitted fabrics, sewing threads, chenille yarns, home textile fabrics, high-strength ribbon ropes, laces, shirt collars, clothing linings, automotive interiors, and automotive airbags. It is also widely used in fields that require heat bonding, such as flat knitting, hosiery knitting, circular knitting machines, and warp knitting machines.
One of the main advantages of heat-melt nylon fiber is its ability to bond with a wide range of fabrics, including natural and synthetic fibers. It can be used for bonding fabrics of different weights and thicknesses without compromising the softness and flexibility of the fabric. The bonding process is also quick and efficient, making it ideal for high-speed manufacturing processes.
In terms of material properties, heat-melt nylon fiber is known for its high strength, wear resistance, resistance to chemicals, resistance to washing, and dry cleaning. It also has good breathability and waterproof properties and is environmentally friendly. This fiber solidifies quickly after melting, providing a soft and comfortable feel, with better elasticity and adhesion.
It is worth noting that there is also a heat-bonded nylon fiber 100D on the market made of 100% polyester, with a melting point of 110°C, commonly used in the textile industry where heat bonding is required. This fiber is characterized by its excellent bonding ability, high strength, thermal reactivity, flexibility, durability, and lightweight nature, and is used in various fields such as textiles and apparel, footwear, industrial fabrics, automotive, home textiles, and medical textiles.
