What is polyamide?
Polyamides are among the most important engineering thermoplastics but are also processed into fibers in enormous quantities. Polyamides are tough materials that are characterized by high strength and elongation. Good abrasion and wear resistance as well as water-repellent properties permit many applications, especially in the clothing industry. Best known are nylon tights and technical fabrics for outdoor textiles or balloon and parachute lines. Various derivatives of the polyamide molecule increase the utility value depending on the requirements for temperature, strength, and elongation.

Recycled Nylon Fabric
Recycled nylon, also known as “nylon return material,” is generally produced by smelting and granulating nylon yarn, nylon filament or nylon fabric.
Advantages
- Recycled nylon has good abrasion resistance, heat resistance, oil resistance and chemical resistance, and also greatly reduces the water absorption and shrinkage rate of raw materials, and has excellent dimensional stability and excellent mechanical
Nylon SF (for spinning)
Nylon SF is characteristically soft and strong and can supplement, substitute, or mix with natural wool. It addresses wool’s weaknesses, increasing productivity and reducing the cost of worsted-spinning manufacturers. Nylon SF can be found in everyday items in the form of cotton roving, wool, and angora.

1. Soft texture
2. Durable
3. Temperature-resistant
4. Elastic
– Applications
Cotton roving, worsted spinning, woolen
Uniforms, apparel

Nylon SF (for non-woven fabric)
Nylon SF can be used to make high-density non-woven fabric by blending with PET. The resulting product is referred to as a needle-punching non-woven fabric, which is used to manufacture synthetic leather. It can be treated with hydrophilic oil if PU coating is required.
– Benefits
1. Soft texture
2. Durable
3. Temperature-resistant
4. Elastic
– Applications
Non-woven fabric, interlining, felt, synthetic leather

Dope-dyeing (for carbon-black)
Dope-dyed chips in a variety of colors can be mix-spun in polymer form using the master batch method to achieve vibrant and consistent colors that stay. Blackness and colorfastness are superior to those achieved with post-dyeing. Dope-dyed fiber can be mix-spun with other fibers to achieve a wide array of colors.
– Benefits
1. Semi-permanent colors and colorfastness
2. Vibrant and consistent colors
3. Mix-spin results in a variety of colors

Bi-component compound fiber (for heat-sealing)
A bicomponent compound fiber is a compound-spun fiber made from PE and PP or a PE and PET sheath-core. A low-melting-point polymer (PE) acts as the sheath and a high-melting-point polymer (PP or PET) as a core in the making of heat-sealing nonwoven fabric. Heat-sealing doesn’t need any glue because the low-melting-point fiber melts easily, making it a safe and environmentally friendly product.
