Embodiment 1
[0021] A kind of manufacture method of vinylon polyester through-filament, it comprises the following steps:
[0022] 1) Doubling, merging one strand of 333 polyester yarn and two strands of 29.5tex vinylon stretch-cut yarn into one strand;
[0023] 2) Initial twist, twist direction Z, number of strands twist is twist / 100cm;
[0024] 3) Double twisting, twist direction S, number of strands twist is twist / 100㎝,
[0025] 4) stranded wire, with the twisted strand in (3), is wound into stranded wire by the yarn reeling machine;
[0026] 5) Sizing and dyeing in the slurry tank, the concentration of the slurry is 10-20%, the dyestuff is 0.0010-0.0020% of the total slurry, the strands are put into the adjusted slurry, and the soaking time is 40 minutes to 70 minutes;
[0027] 6) dehydration, 60-70% sizing is removed by a dehydrator for the sizing vinylon polyester stranded wire in step (5);
[0028] 7) Stretching and setting for the first time, air-drying, humidity is lower than 3...
