AI Technical Summary

Problems solved by technology

Aluminum film composite protective clothing has good thermal radiation performance, but aluminum itself is not resistant to high temperature and cannot protect molten metal. This protective clothing also has the disadvantage of poor air permeability, so the protective function and comfort cannot meet the requirements.
Protective clothing made of blended fabrics can only be used as ordinary flame-retardant protection, and cannot be adapted to some special high-temperature workplaces
In order to improve the protective effect, the flame-retardant cloth is thickened. The protective clothing made in this way is particularly thick and inconvenient to operate, and it is still ineffective against molten metal splashing
Others use mineral fibers such as glass fiber, asbestos, etc. as flame-retardant materials, which have been banned due to their harm to the human body.
There is also a type of high-temperature protective clothing that uses airflow or built-in cooling materials to cool the inside of the clothing. This type of protective clothing has a complex structure and is expensive, and it cannot fundamentally solve the threat of the external working environment to the human body.
[0006] In addition, most of the flame-retardant protective clothing currently used in the industrial field in my country is flame-retardant cotton fabrics. The flame-retardant properties of these flame-retardant cotton fabrics usually decrease with the increase in washing times, and the flame-retardant cotton fabric After treatment, mechanical properties such as breaking strength, tearing strength are usually greatly reduced, thereby reducing its service life

Abstract

The invention provides flame-retardant protective clothing fabric, and relates to textiles, in particular to the flame-retardant protective clothing fabric. The flame-retardant protective clothing fabric is formed by weaving flame-retardant yarn comprising the following fibers by total weight: 50 to 60 percent of wool fiber, 15 to 30 percent of polyphenyl thioether fiber and 10 to 35 percent of flame-retardant viscose fiber. The flame-retardant protective clothing fabric is light, safe, and favorable in mechanical property, chemical stability and temperature resistance; and the working safety of a person wearing the flame-retardant protective clothing fabric is improved. The flame-retardant protective clothing fabric is high in strength, tearing resistance, stretching resistance and friction resistance, not only has permanent flame retardancy, but also can effectively prevent splashing of molten metal liquid drops, is high-temperature resistant, and can keep the integrity, the wearing comfort and the like of clothes.

Description

[0001] technical field [0002] The invention relates to textile fabrics, in particular to a flame-retardant protective clothing fabric. Background technique [0003] Personnel working in special environments such as firefighting, metallurgy, electric power and other industries must wear thermal protective clothing to protect the body from high temperature or prevent splashed high-temperature substances from causing harm to the human body. With the development of my country's economy and the continuous improvement of the legal system, people's awareness of protecting their health is increasing, and a new concept of flame-retardant protective clothing has also been proposed: green, pollution-free, comfortable, durable and cheap. [0004] At present, most thermal protective clothing adopts flame-retardant fabrics, which can realize the protective function by blocking heat energy so that it cannot reach the surface of human skin. However, in some special operations such as th...
