Coal mine protective clothing is used for coal miners to wear when working to prevent common injuries, dirt and electrostatic accumulation, and has the function of flame retardant clothing. Based on the investigation and analysis of the underground environment of coal mine and workers’ operation,aramid insulation supplier the company has conducted a systematic study and design of the performance of the protective clothing fabric for coal mine workers. The concept of the protective clothing for coal mine is first proposed, and the performance design of the protective clothing fabric for coal mine is emphasized. Through advanced textile technology, the fabric is given special functions, such as: high strength, wear resistance, flame retardant and anti Static electricity, so as to meet the requirements of modern coal mine safety production, build a solid and reliable safety line for coal mine staff, provide better work protection for underground miners, but also to avoid man-made mining accidents to lay the foundation. This paper focuses on the basic performance of protective clothing fabric used in coal mine, mainly through the following steps. First of all, the basic mechanical properties of the fibers were tested by laboratory conditions when the experimental scheme was designed.aramid insulation supplier
aramid insulation supplier On the basis of understanding the properties of fiber,aramid insulation supplier the mixed yarn of Kevlar and cotton was spun, and the double twill fabric with different composition and blending ratio was woven. The basic properties of the blended yarn and fabric were tested, including the mechanical properties of the yarn, the unevenness of the strip, the strength of the fabric, the wear resistance, the flame retardant and the anti-static properties. A large number of experimental data and rules of the basic properties of the fiber, yarn and fabric were obtained. Secondly, in the theoretical analysis, on the basis of professional knowledge analysis, orthogonal experimental design and mathematical evaluation method, the experimental data were comprehensively analyzed and processed, and on this basis, the influence of raw material combination, fabric structure, variety specifications and other factors on the fabric performance was analyzed. The test results show that the best scheme of protective clothing fabric is the blending ratio of Kevlar and cotton fiber of 5/95, yarn length of 20s and double layer of 3/1 twill fabric. Its comprehensive properties of strength, wear resistance, flame retardant and anti-static are obviously better than those of pure cotton ordinary work clothes used in coal mine. Finally, I hope to prove through the paper that relying on advanced textile and garment technology, new materials can be used to replace pure cotton products, which are more suitable for the complex mine environment and provide better work protection for underground workers. This study has great significance to guarantee the safety of people’s life and property, promote the sustained and steady development of our coal industry, and accelerate our socialist modernization process. It is hoped that through the research of this paper, it can play a role in promoting the revision and formulation of the national standard and industry standard of miners’ work clothes, so as to further provide practical guarantee for the safety production of our coal industry.
