Embodiment 1

[0039] A main rope of a plastic-coated water skiing rope and a manufacturing method thereof, comprising the following steps:

[0040] (1) Take 3 ultra-high molecular weight polyethylene filaments with a specification of 1000D, twist and combine them into one yarn on a ring twister, the twist direction is Z direction, and the twist is set to 20 twists / meter to make warp yarn 5.

[0041] (2) Get 16 warp yarns that above-mentioned step (1) obtains, arrange on the loom in parallel, get two 250D ultra-high molecular weight polyethylene multifilaments without twisting, as weft yarn 7 and overlock thread 8 respectively. Through the opening and closing movement of the loom and the reciprocating movement of the weft yarn, the warp yarn 5 and the weft yarn 7 are interwoven to form a closed structure, and the overlock thread 8 is trimmed on one side to obtain a non-sandwich woven rope with a linear density of 5.7 g / m.

[0042] (3) Import the non-sandwich woven rope index obtained in step...

Embodiment 2

[0045] A main rope of a plastic-coated water skiing rope and a manufacturing method thereof, comprising the following steps:

[0046] (1) Take 3 ultra-high molecular weight polyethylene filaments with a specification of 800D, twist and combine them into one yarn on a ring twisting machine, the twist direction is Z direction, and the twist is set to 20 twists / meter to make warp yarn 5.

[0047] (2) Take a single filament of ultra-high molecular weight polyethylene with a specification of 1600D and twist it on a ring twisting machine. The twist is set to 20 twists / meter, and the twist direction is Z or S direction, and the twisted filament is used as a rope core 1.

[0048] (3) Get 16 warp yarns that the above step (1) obtains, 4 S direction rope cores that step (2) obtains and 4 Z direction rope cores are arranged in parallel, introduce on the loom, get two 250D ultra-high molecular weight Polyethylene multifilaments are not twisted, and are used as weft yarn 7 and overlock th...

Embodiment 3

[0052] A main rope of a plastic-coated water skiing rope and a manufacturing method thereof, comprising the following steps:

[0053] (1) Take 3 ultra-high molecular weight polyethylene filaments with a specification of 800D, twist and combine them into one yarn on a ring twisting machine, the twist direction is Z direction, and the twist is set to 20 twists / meter to make warp yarn 5.

[0054] (2) Take 5 ultra-high molecular weight polyethylene filaments with a specification of 800D, and carry out preliminary twisting on a ring twister to form a yarn, the twist is set to 40 twists / meter, and the twist direction is S direction; take three to complete the initial The twisted yarn is re-twisted on the ring twister, the twist is 20 twists / meter, and the twist direction is Z direction, and three twisted yarns 6 are made as the rope core 1.

[0055] (3) Get 16 warp yarns obtained in the above step (1), and 1 rope core obtained in the step (2), arrange them in parallel, and introduce...

Abstract

The invention provides a plastic-coated water skiing rope main rope. The plastic-coated water skiing rope main rope comprises a woven rope layer, a heat insulation layer and a plastic-coated layer; heat-resistant polymer fabric, non-woven fabric, a film or glass fiber cloth is adopted between the woven rope layer and the plastic-coated layer to serve as the heat insulation layer, and the thickness of the heat insulation layer is smaller than 0.5 mm; the plastic-coated layer is formed by melting and extruding raw materials and then uniformly coats the outer part of the heat insulation layer; the woven rope layer comprises a rope sheath and a rope core; the rope sheath is tightly coated outside the rope core; the rope sheath is woven into a tubular structure by adopting a weft guide knitted belt; the rope core consists of at least one three-strand twisted thread or a plurality of parallel yarns; and the diameter of the water skiing rope main rope is 4-8mm. The the water skiing rope main rope has the characteristics of high strength, small extension and the like, and the diameter can be greatly reduced under the condition of ensuring the strength.

Description

technical field [0001] The invention relates to a method for making a main rope of a plastic-coated water skiing rope, and belongs to the technical field of ropes for water skiing. Background technique [0002] Water skiing is a water sport in which people "walk" on the water surface with the help of power traction. As an essential equipment for water skiing, the quality of the water skiing rope directly affects the quality of water skiing. The water skiing rope is mainly composed of a grip rod, a protective cover, a connecting rope and a rope body part, and the rope body part is called the main rope. The main rope of the water skiing rope is mainly made by twisting and weaving: due to the requirements of rope diameter and hand feel, the twist of the yarn during the twisting process far exceeds its critical twist coefficient, which is likely to cause loss of rope strength; Twisting, the yarns interpenetrate and intersect each other, and the yarn rotates 360° around the rope...
