Vinylon/polyester oil harness string production process and product thereof

Abstract

The invention provides a vinylon / polyester oil harness string production process and a product thereof. The production process comprises the following steps: 1) plying; 2) first twisting; 3) second twisting; 4) winding the plied yarn, which is formed after second twisting and the twisting degree of which is 180-270, by a yarn reeler to form a stranded yarn; 5) carrying out size mixing in a pulp chest; 6) putting the stranded yarn into the mixed size; 7) removing 60-70% of the size in the vinylon / polyester stranded yarn, which is sized, by a dehydrator; 8) carrying out drafting and setting for 15-25 minutes by a yarn waxing machine on the sized stranded yarn; 9) carrying out drying on the stranded yarn obtained through first drafting and setting, the humidity being lower than 3%, and the wax temperature being 90-130 DEG C; and 10) putting the dried stranded yarn into a wax bucket and lifting the stranded yarn after being soaked for 5-10 minutes, and then, carrying out second drafting and setting by the yarn waxing machine. The breaking strength of the vinylon / polyester oil harness string provided in the invention is obviously improved; the ratio of expansion and contraction thereof is reduced; and the friction coefficient is improved by 30%-60%.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a production process and a product of a polyester oil through silk thread. 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 polyester thread 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. Espec...

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
