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)...
