| Abstract: | A semi-dull porous fine PA 66 elastic fiber of 78 dtex/68 f was produced from semi-dull PA66 chips with the relative viscosity of 2.47.The spinning process was optimized.The results showed that the PA66 pre-oriented yarn of 93 dtex/68 f can be produced smoothly with the breaking strength 3.98 cN/dtex and elongation at break 58.36% and PA 66 elastic fiber of 78 dtex/68 f with the breaking strength 4.33 cN/dtex and elongation at break 23.42% when PA 66 chip drying temperature was 95-100℃,drying time 20-25 h,spinning temperature 292-295 ℃,collection position 800 mm from the spinneret,winding speed 4 150 m/min,cross air blow speed 0.55 m/s,spinpack pressure 16-17 MPa,oil up-take 0.65%. |
