Problems solved by technology

[0002] At present, ordinary nylon and polyester insulating ropes used in live work in my country do not have moisture-proof performance, so they cannot be used when the relative humidity reaches 85% or more, and must be stored in a dry room. Long-term live work in the field is affected by weather and humidity. The impact of live work is more dangerous, especially in the process of live work, sudden thunderstorms will cause great harm and loss to people and electrical equipment. This is a problem that has not been solved for a long time in the live work industry.

Embodiment 1

[0015] Example 1: Comparing the drawings, (1) chemically synthetic fibers such as nylon and polyester fiber materials are combined and twisted into fine threads; (2) for dyeing treatment, the dyes are azo-based disperse yellow and Anthraquinone disperse red, dye to material ratio is 1:100, bath ratio is 1:20-30, add glacial acetic acid to adjust PH to 4-5, control temperature is about 130℃, control time is about 30min, (3 ) After dyeing into orange, cool to 70-80℃, drain the water, and then enter the waterproof finishing process (4). The finishing liquid is oleophobol-SL, which is compared with the material 1:10, bath ratio 1:20-30, add glacial acetic acid to adjust PH to 5-6, control temperature at about 130℃, control time for about 30min, (5) After draining and drying, enter into finishing Set the shape (6), control the temperature at about 180℃, and the time is 20-40min, and (7) make the rope finished product.

Embodiment 2

[0016] Example 2: Comparing the drawings, (1) the chemically synthetic fiber material is combined and twisted into fine threads, (2) is dyed, and the dyes are azo-based disperse yellow and anthraquinone-based dispersion Red, dye to material ratio 1:100, bath ratio 1:20-30, add glacial acetic acid to adjust PH to 4-5, control temperature at about 130℃, control time for about 30min, (3) After dyeing orange red After cooling to 70-80℃, drain the water, and then enter the waterproof finishing process (4). The finishing liquid is made of silicone water repellent H, a methyl hydrogen-containing silicone oil emulsion, with a concentration of 100g / l Adjust the PH to 5-6, the temperature is 130°, and the control time is about 30min. (5) After draining and then enter the drying process, the drying temperature is about 80-90℃, (6) After finishing and shaping, The temperature is controlled at about 180°C, and the time is 30-40min. (7) The rope is then made into a finished product.

Abstract

The invention uses chemical fiber materials, the manufacturing method is: the materials are combined and twisted into cord, uses azo disperse yellow and antraquinone disperse red to dye them, then carries on water-protection trimming craft, the trimming liquid is oleophobic water resisting agent, such as organic silicon or fluorin polymer, adds in glacial acetic acid to regulate the pH value, controls the time and temperature, then they are dried and formed into cord.

Description

Technical field [0001] The invention relates to the technical field of ropes made of chemical synthetic fiber materials. Background technique [0002] At present, the ordinary nylon and polyester insulated ropes used for live work in our country are not moisture-proof, so they cannot be used when the relative humidity reaches 85% or more. Storage and storage must be placed in a dry room. Long-term live work in the field is subject to weather and humidity. The impact of live work is relatively dangerous, especially during the process of live work, sudden thunderstorms cause great harm and loss to people and electrical equipment. This is a problem that has not been solved in the live work industry for a long time. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a live operation that has a greater improvement in moisture-proof performance compared with the prior art, makes storage and storage more ...
