Problems solved by technology

Among them, most of the existing caving ropes are made of polypropylene and polyester materials, the product quality is poor, the aging resistance and waterproof performance are poor, and there is no reflective function, no thermal drafting and setting, and the elongation rate is too large. Accurate, according to the characteristics of the cave and the protection of the cavers, there is an urgent need for a cave rope that is easy to carry, high in breaking strength, low in elongation, good in waterproof performance, good in wear resistance, and long in service life.

Embodiment 1

[0053] A method for making a caving rope, the steps of which are:

[0054] 1) Material selection: choose nylon, polyester or aramid fiber filaments to make the rope sheath 1, and choose nylon fiber filaments to make the rope core 3;

[0055] 2) Rope sheath twisting: the specification is 3*840D rope sheath-1, the twist is set to 120 twists / m, twisted by the ring twisting machine and combined into one strand, and the width specification is 0.3mm rope sheath-22 No twisting spare;

[0056] 3) Preparation of coating finishing solution: prepare coating finishing solution, the ratio of water and ICOATS-REPEL in the coating is: 20%: 80% or the ratio of water and HUNTSMAN-PHOBOL-NB-NH is: 30%: 70% in Stir in the container with a magnetic stirrer until uniform;

[0057] 4) Rope core initial twist: take (6 pieces) * (840D) rope core 3 to twist, and the initial twist twist is 220 twists / m;

[0058] 5) Rope core retwisting: after the initial twisting, take 3*(6 pieces)*(840D) rope core ...

Abstract

The invention discloses a spelunking rope manufacturing process which sequentially comprises the following nine implementation steps of selecting materials, twisting a rope sheath, preparing a coatingfinishing liquor, carrying out first twisting on a rope core, carrying out second twist on the rope core, pre-knitting the rope sheath, spooling, knitting, and setting a coating. According to the spelunking rope manufacturing process provided by the invention, a rope body is designed, the rope sheath adopting chinlon, dacron or aramid fiber filaments as a main body and the rope core adopting chinlon fiber filaments as a main body are used, the rope sheath and the rope core are knitted into a rope, and the rope is subjected to coating finish, tensioning, heat drawing and setting, so that the rope has the characteristics of light weight, easiness in carrying, high breaking strength, low elongation, good waterproofness, good abrasive resistance and long service life so as to be used as a spelunking rope for spelunking exercise. The spelunking rope manufacturing process provided by the invention is technological innovation expanding the existing technology so as to have better popularization and application values.

Description

technical field [0001] The invention relates to the technical field of safety ropes, in particular to a manufacturing process of a cave-exploring rope. Background technique [0002] Cave exploration, referred to as caving, is an outdoor sport that combines people's curiosity with sports and tourism, and it is also a stimulating activity. During the cave exploration, each member must concentrate on completing the exploration tasks he undertakes, and at the same time, he must independently implement various contingency measures in emergency situations, so that he and his companions can safely and smoothly escape the danger. The "independently" mentioned here includes not only rich knowledge, but also superb and comprehensive caving skills and perseverance. [0003] A technique used in caving is called SRT technique, the full name is Single Rope Technique, that is, single-rope technique. Single-rope technique includes single-rope ascent and descent. Generally speaking, it is u...
