Embodiment 1

[0019] A kind of production technology of dimension polyester hook line, comprises the following steps:

[0020] 1) For the yarn, two 333dtex-420dtex high-strength low-elongation polyester filaments and two 29.5tex vinylon stretch-cut yarns are combined into one strand;

[0021] 2) Pre-twisting, twisting direction Z, number of strands twist is twist / 100㎝, twisting is carried out with 1 strand that has been merged, and the twist is 360-466;

[0022] 3) Double twisting, twisting direction S, number of strands and twisting twist / 100㎝, synthesize 3 strands with the first twisting, and then twisting, the twisting degree is 180-270;

[0023] 4) The strands with a good twist of 180-270 are wound into stranded wires by a yarn reeling machine;

[0024] 5) Sizing and dyeing in the slurry tank, the concentration of the slurry is 10-20%, and the dyestuff is 0.0010-0.0020% of the total slurry, and they are put together to adjust the slurry;

[0025] 6) Put the stranded wire into the ad...

Abstract

The invention provides manufacturing technology of a polyvinyl-polyester hook wire. The manufacturing technology comprises the follow steps : 1) performing wire merging; 2) performing first twisting; 3) performing second twisting; 4) winding the twisted compound wire, the twist degree of which is 180-270, into a stranded wire with a yarn reeler; 5) performing slurry mixing in a slurry pool; 6) putting the stranded wire into the adjusted slurry; 7) removing 60-70% of slurry from the sized polyvinyl/polyester compound wire with a dehydrator; and 8) performing drawing setting of the sized compound wire through a wire waxing machine for 15-25 min, when the dryness of the obtained polyvinyl/polyester harness wire reaches 70-80%, performing manual waxing for 2-3 min, and performing air-drying after the wire passes through the wire waxing machine till the humidity is less than 3% to prepare the polyvinyl-polyester hook wire. The prepared polyvinyl-polyester hook wire is obviously enhanced in breaking strength, and reduced in expansion and contraction, and the friction coefficient is raised by 30-60%.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a production process of a polyester hook thread. Background technique [0002] At present, the weaving width of the jacquard loom is increasing, which puts forward higher requirements for the harness. For this reason, the development of a harness with high strength and low stretching rate has been used 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 polyester hook thread made by the common method 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 the season wh...
