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...

Abstract

The invention provides a method for manufacturing a polyvinyl terylene harness cord, and the method comprises the following steps: 1) doubling threads; 2) primarily twisting the threads; 3) retwisting the threads; 4) winding the threads; 5) mixing slurry in a slurry pool and dyeing the threads; 6) carrying out dehydration; 7) carrying out first drawing for shaping and air drying until the humidity is lower than 3%; and 8) carrying out second drawing for shaping. A product produced by the invention has a substantially enhanced breaking tenacity and a reduced expansion and contraction ratio, and the friction coefficient is increased by 30-60%.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for manufacturing a vinylon polyester harness. Background technique [0002] At present, the weaving width of the jacquard loom is increasing, which puts forward higher requirements for the harness. Therefore, the development of a harness with high strength and low stretching rate is already the best way to ensure that the shed of the jacquard loom is clear and weaves smoothly. An urgent need. At the same time, the high-strength, low-stretch harness can effectively reduce the warp defects of the fabric. [0003] At present, the vinylon polyester harness made by common methods has low tensile breaking strength. The expansion and contraction of the harness is relatively large under a small load. When the product is in the weaving factory, due to the large amount of expansion and contraction of the harness, the normal production is affected. Especially in t...
