Nylon Staple Fiber (Polyamide Fiber)
Excluding natural fibers and regenerated cellulose fibers, which hold an irreplaceably important position in the global fiber output, which type ranks second among synthetic fibers? Yes, it is polyamide fiber, second only to polyester fiber. Moreover, the proportion of chemical fibers has been increasing year by year, gradually replacing the dominant position of natural fibers, which demonstrates the significance and development potential of chemical fibers.
Nylon boasts the best wear resistance among all fibers. It has a low density, being as light as a feather; it is as soft as cashmere; its moisture regain rate is around 4.5%, featuring excellent hygroscopicity; it is easy to dye; it has a natural cooling sensation; it exhibits antibacterial properties; and it has good resilience. It is a fiber with numerous outstanding advantages.
In addition to the above merits, polyamide fiber can also be processed into differentiated and functional fibers. For example:
· High-strength polyamide staple fiber: Produced via special processes and equipment, it has a breaking strength of over 7 cN/dtex. It can significantly enhance the breaking strength and tear resistance of blended yarns and fabrics, and is mainly used in military uniforms, safety protective clothing, and industrial uniforms.
· High-quality polyamide staple fiber: Leveraging its wear-resistant, lightweight and skin-friendly properties, this type of fiber is manufactured as spinnable polyamide staple fiber with low defects, to meet the demand for high-quality yarns and fabrics, and cater to skin-friendly sportswear scenarios. Its main applications include yoga wear, Tai Chi uniforms, dance costumes, and underwear series.
· Heteromorphic cross-section fiber: Common cross-section shapes include Y-type, triangular, and cross-shaped. This fiber endows fabrics with enhanced luster, moisture-wicking, and anti-pilling performance, and is mainly applied in moisture-wicking sportswear, ethnic costumes, and home textile fabrics.
· Cooling and antibacterial fiber: Made by adding antibacterial agents into the fiber, it possesses cooling and antibacterial properties, and is suitable for sports underwear and shirt series.
There are also other health-care functional varieties, such as magnetically modified polyamide fiber and coffee carbon fiber.
From an environmental protection perspective, the wear resistance, durability, and recyclability of polyamide fiber are well aligned with the current social demands, making it an excellent product among chemical fibers.
