HIGH-SPEED SPINNING OF MULTIFILAMENT YARN OF POLYAMIDE YARN

摘要

PROBLEM TO BE SOLVED: To provide a method for stably spinning polyamide yarns into an ultra multifilament yarn at a high speed. ;SOLUTION: A polyamide of ultra multifilament yarn of ≥12 yarns is simultaneously subjected to melt spinning, cooled and solidified. Each yarn is individually supplied with an oil and interlaced. The whole yarns are simultaneously taken off by a first godet roller 5, wound around a single second godet roller 6 which is rotated at a higher speed than the first godet roller 5 and has a surface temperature heated to ≥110°C. Successively the whole yarns are taken up at ≥3,500 m/minute at the same time to spin the objective ultra multifilament yarn of polyamide yarn at a high speed.;COPYRIGHT: (C)2000,JPO
