Problems solved by technology
[0002] In various fields such as mountaineering, outdoor sports, construction, fire fighting, rescue, etc., it is necessary to use ropes, especially ropes with wear-resistant and high-temperature resistance. Among the existing wear-resistant and high-temperature resistant ropes, there is no nylon fiber Ropes, because the existing nylon fiber ropes are not wear-resistant and high-temperature-resistant during use, the service life of the existing nylon ropes is greatly reduced, and there are potential safety hazards in use due to their non-wear-resistant and high-temperature resistance, which limits Application of nylon fiber rope

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention.
[0018] A method for preparing a wear-resistant and high-temperature-resistant rope, the first embodiment, the steps are:
[0019] a. Doubling: Merge 6 nylon fiber filaments into one strand of nylon fiber filaments;
[0020] b. Twisted thread: By way of twisted thread, 8 strands of nylon fiber filaments are paralleled and 4 high-strength polyester filaments are twisted to form a twisted thread, wherein the twisting speed is set to 140 rpm, and the twist Set it to 75 twists / m, and set the tension to 14.5N;
[0021] c. Preparation of the rope core: integrate the three strands of twisted yarn together, place it in a temperature of 120°C and a pressure of 0.1Mpa for 30 minutes, heat-setting, and obtain the rope core;
[0022] d. Pre-weaving: by weaving, accordin...

A wear-resistant and high-temperature-resistant rope and its preparation method, the steps of which are: doubling: twisting: doubling 8 strands of nylon fiber filaments and twisting with 4 high-strength polyester fiber filaments by way of twisting Become a twisted yarn, where the twisting speed is set to 150 rpm, the twist is set to 80 twists / m, and the tension is set to 15N. Put it in a pressure of 0.1-0.15Mpa for 30-80 minutes, heat-setting, and make a rope core; pre-weaving: by weaving, according to 12 strands of twisted yarn as the S twist direction and 12 strands of twisted yarn as the Z twist direction, in the rope The core is braided into an outer body to obtain the rope intermediate Ⅰ; coating: soak the rope intermediate Ⅰ in polytetrafluoroethylene for 40-80 minutes to obtain the rope intermediate Ⅱ; forming a rope: put the rope intermediate Ⅱ in Dry in an oven at 150-200°C to obtain a rope. Due to the design of the rope body, the nylon fiber filament is used as the main body, and the layer body coated with polytetrafluoroethylene on the outer surface, so that the rope has the performance of wear resistance and high temperature resistance.
Description
1. Technical field [0001] The invention relates to a rope and a preparation method, in particular to a wear-resistant and high-temperature resistant rope and a preparation method. 2. Background technology [0002] In various fields such as mountaineering, outdoor sports, construction, fire fighting, rescue, etc., it is necessary to use ropes, especially ropes with wear-resistant and high-temperature resistance. Among the existing wear-resistant and high-temperature resistant ropes, there is no nylon fiber Ropes, because the existing nylon fiber ropes are not wear-resistant and high-temperature-resistant during use, the service life of the existing nylon ropes is greatly reduced, and there are potential safety hazards in use due to their non-wear-resistant and high-temperature resistance, which limits Application of nylon fiber rope. 3. Contents of the invention [0003] In order to overcome the above-mentioned technical shortcomings, the object of the present invention is...
