| Abstract: | A fine-d enier PA 66 FDY of 11.1 dtex/7 f was prepared from PA66 chip with the relative viscosity of 2.53 by onestep process.The effects of drying,spinning and winding processes on the production and product quality were discusssed.The results showed that the production proceeded smoothly and yielded high product quality when the process conditions were as followed: moisture content of chip 1 300-1 400μg/g,spinning temperature 292-295℃,draw ratio 1.4-1.5,heat setting temperature 180-185℃,winding speed 4 400-4 500 m/min.The obtained fiber had the breaking strength of 5.08 cN/dtex,elongation at break 42.9%and yarn irregularity 1.36%. |
