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

[0020] 1, a kind of manufacture method of high-strength wear-resistant vinylon harness, it comprises the following steps:

[0021] 1) Doubling, merging 1 hose vinylon yarn and 2 vinylon filter tows into 1 strand;

[0022] 2) Initial twist, twist direction Z, number of strands twist is twist / 100cm;

[0023] 3) Double twisting, the twisting direction is S, the number of strands and the twist is twist / 100㎝;

[0024] 4) stranded wire, with the twisted strand in (3), is wound into stranded wire by the yarn reeling machine;

[0025] 5) Then dip the vinylon stranded wire into the slurry, and the ratio of raw materials by weight of the slurry is as follows:

[0026] 40-60 parts of polyvinyl alcohol, 5 parts of polyoxyethylene ether penetrant, 60 parts of water; the concentration of the slurry is 6%, the soaking time is 5 hours, and sizing at room temperature;

[0027] 6) dehydration, the sizing vinylon stranded wire in step 5) removes 70% of the slurry by a dehydrator;

[0028] 7)...

Abstract

A manufacturing method of high-strength abrasion-resisting vinylon harness cords comprises the following steps of 1 doubling, 2 primary twisting, 3 secondary twisting, 4 stranding, 5 pulp mixing and dyeing in a pulp chest, 6 dehydration, 7 first-time drafting and setting and air drying and 8 second-time drafting and setting, wherein the humidity is lower than 3% through first-time drafting and setting and air drying. The breaking strength of the vinylon harness cords manufactured by means of the manufacturing method is remarkably improved, the abrasion resistance is improved, the ratio of expansion and contraction is reduced, and a frictional coefficient is improved by 30% to 60%.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for manufacturing a high-strength wear-resistant vinylon polyester harness. Background technique [0002] At present, the weaving width of the jacquard loom increases, which puts forward higher requirements for the harness. Therefore, the development of a harness with high strength, wear resistance, and low stretching rate is already to ensure that the shed is clear when the jacquard loom is opened. The urgent need for smooth weaving. At the same time, the high-strength, wear-resistant, and low-stretch harness can effectively reduce the warp defects of the fabric. [0003] At present, the vinylon 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,...
