1. Abrasion resistance: Under the same conditions, the abrasion resistance of polyamide fiber is 10 times that of cotton and 20 times that of wool. If 15% polyamide fiber is mixed into wool or cotton spinning, its wear resistance will be 3 times higher than that of pure wool or cotton.
2. Breaking strength: The breaking strength of long polyamide fiber used for clothing is 5.0~6.4g/d, and the high-strength yarn for industrial use is 7~9.5 g/d or even higher. The breaking strength of the wet state is about dry 85%~90% of the state.
3. Elongation at break: The elongation at break of polyamide fiber varies with different varieties. The elongation of strong yarn is as low as 10-25%, and that of yarn for general clothing is 25-40%. The elongation is about 3~5% higher than that in the dry state.
4. Elastic recovery rate: Polyamide fiber has good resilience. When the elongation of long fiber is 10%, its elastic recovery rate is 99%.
Nylon staple fibers can also be made into differentiated functional fibers. For example: high-strength nylon staple fiber is manufactured with special technology and equipment, and its breaking strength is greater than 7cn/dex, which can greatly improve the breaking strength of blended yarns, fabrics, and tear. Mainly used in military uniforms, safety protective clothing, industry uniforms, etc.
