Along with social development, living standards and working conditions progressive improvement, the people start to devote to fire, the electric power, the coal mine profession special environment work clothing's research. The clothing is playing the very important role as the human body second skin, its lining comfortableness and durable immediate influence operating personnel's working efficiency and health. The coal mine shaft production environment is bad, the worker works shoulders in a big way, to general worker physical and moral integrity existence very tremendous influence, but the coal mine shaft high temperature humidity's working conditions, cause worker's working condition change are worse, to worker's physiology and psychological influence also more serious [1]. In the downhole operation condition, the clothing and the human body formation “the microclimate” has the high temperature humidity condition. The operating personnel in such “the microclimate”, easy to cause the hot stress to respond that causes metabolism disorder. Crosses Gao Guoshi the environment similarly is also very serious regarding the clothing lining comfortableness and the durable influence. It is well known, downhole operation personnel work clothes many by purified cotton cotton duck primarily. In the downhole operation environment's inorganic acids material easy to cause its lining textile fiber to destroy rapidly, simultaneously under the high temperature staff's sweat will also destroy the cotton fibre, will cause its lining force to reduce. Because the cotton fibre is in itself not wear-resisting, the elasticity is bad, causes its work clothes the service life to sell at a discount greatly under such environment, simultaneously also with difficulty conforms to the national labor insurance clothing's use standard. |
