Problems solved by technology

The product is in the weaving factory, due to the large amount of expansion and contraction of the harness, it affects the normal production
Especially in the season when the air humidity is high, the expansion and contraction of the harness becomes larger, seriously reducing the weaving efficiency of the loom, and it is easier to cause warp defects of the fabric, and even the breakage of the harness

Embodiment 1

[0021] A production method of vinylon polyester white silk thread, comprising the following steps:

[0022] 1) For the yarn, one strand of 333dtex-466dtex polyester yarn and two strands of 29.5tex vinylon stretch-cut yarn are combined into one strand;

[0023] 2) Pre-twisting, twisting direction Z, number of strands, twisting twist / 100㎝, twisting with 1 strand that has been merged, and the twisting degree is 466-610 / m;

[0024] 3) Double twisting, twisting direction S, number of strands twist is twist / 100㎝, synthesize 3 strands with primary twisting, and then twist, twisting is 240-320 / m;

[0025] 4) Take the double-twisted 240-320 strands and wind them into stranded wires by the spinning machine;

[0026] 5) Sizing in the slurry tank, the concentration of the slurry is 15-25%;

[0027] 6) Put the stranded wire into the adjusted slurry, soaking time is 40 minutes to 70 minutes;

[0028] 7) Sizing the polyester stranded wire, remove 60-70% of the slurry by the dehydrator;

Abstract

The invention provides a vinylon and polyester white harness thread and a production method thereof. The production method comprises the following steps: 1) carrying out doubling; 2) carrying out first twisting; 3) carrying out second twisting; 4) winding 240-320 strands subjected to second twisting into a stranded thread by a yarn reeler; 5) mixing size in a size pool; 6) putting the stranded thread in the mixed size; 7) removing 60-70% of size from the sized polyester / vinylon stranded thread by a dehydrator; 8) putting the sized stranded thread on a waxed thread machine to undergo drafting setting for 15-25 minutes, carrying out manual waxing for 2-3 minutes when the dryness of the polyester / vinylon harness thread is 70-80%, and air-drying the thread after the thread comes off the waxed thread machine until the humidity is lower than 3%, thus preparing the vinylon and polyester white harness thread. The vinylon and polyester white harness thread provided by the invention has the advantages that the breaking strength is obviously enhanced; the ratio of expansion and contraction is reduced; 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 production method and a product of a wester white silk 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 vinylon polyester white-toned yarn produced 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...
