Problems solved by technology
[0003] 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
[0018] 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.
[0019] A method for preparing a wear-resistant and high-temperature-resistant rope, the first embodiment, the steps are:
[0020] a. Doubling: Merge 6 nylon fiber filaments into one strand of nylon fiber filaments;
[0021] 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;
[0022] 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;
[0023] d. Pre-weaving: by weaving, accordin...

The invention relates to a wear-resistant high-temperature-resistant rope and a preparation method. The method includes the steps of doubling; twisting: doubling eight strands of nylon fiber filaments, then twisting the doubled nylon fiber filament strand and four high-strength polyester filaments into a twisted strand by means of twisting at the twisting speed of 150 revolutions / minute and setting the twist as 80 twists / meter and the tension as 15N; rope core preparing: integrating three twisted strands, placing the integrated strand at the temperature of 120-130 DEG C under the pressure of 0.1-0.15MPa for 30-80 minutes for thermoforming so as to prepare a rope core; preliminary weaving: by means of weaving, according to that 12 twisted strands are taken as S twist direction and 12 twisted strands are taken as Z twist direction, weaving on the rope core to form an outer cover so as to prepare a rope intermediate I; coating: soaking the rope intermediate I in polytetrafluoroethylene for 40-80 minutes to obtain a rope intermediate II; rope forming: drying the rope intermediate II in a drying oven at the temperature of 150-200 DEG C to prepare the rope. Due to the design of a rope body, the nylon fiber filaments are used as main bodies, the outer side face is coated with a polytetrafluoroethylene lay body, and thus the rope has wear resistance and high temperature resistance.
