Setting Machine Increasing Nov 01, 2017

China is a textile power, more than 90% of the printing and dyeing enterprises concentrated in Zhejiang, Jiangsu, Guangdong, Fujian and Shandong and other five coastal provinces. Stereotypes machine industry development so far no matter the number of products, the number of enterprises,Setting Machine production and sales and market ownership have been rapid growth, the occurrence of dizzying changes. According to Jiangsu Wuxi Textile Association estimates that in 2010 China only stereotypes of the production has more than 1,000 units Zhejiang Province as a textile province, the number of printing and dyeing enterprises accounted for more than 25% of the total, as of November 2013, only Shaoxing City, Zhejiang Province, Keqiao District 238 printing and dyeing enterprises stereotypes to 1841 units. In recent years, Setting Machine with the printing and dyeing enterprises in the rapid expansion of production capacity, due to stereotypes caused by emissions of environmental complaints and pollution disputes increasing.

Printing and dyeing industry, the production process is complex, Setting Machine in order to improve the appearance of the product, surface properties and dyeing quality, the need to add a variety of textile auxiliaries and solvents. Textiles through the dyeing and rinsing, Setting Machine the need for heat-setting process, the use of the characteristics of the fabric with thermoplastic, in the stereotypes drying tenter and heat treatment, to achieve the purpose of stereotypes.

The temperature of the dry and hot air in the setting machine is usually controlled in the range of 120 to 210 ° C. In the process of shaping, the moisture carried by the fabric with the solvent, grease and wax and other organic compounds together with the heat and volatile, Setting Machine with the waste hot air discharged from the exhaust cylinder, as stereotypes machine exhaust. After the exhaust gas enters the atmosphere, the supersaturated water vapor and the high boiling organic vapor are condensed by the temperature drop, forming a large amount of white water mist and light blue smoke, respectively, which consists of very small particles with viscous particles ; Low-boiling organic matter in the exhaust gas, still in the form of vapor.

Dyeing and finishing machine exhaust gas containing water vapor, auxiliaries and solvents volatile and condensate, and fabric carrying fiber and dust, Setting Machine is a gas, liquid, solid three-state pollutant mixed fluid.

During the transportation and discharge process, the coagulation and adhesion of the soot particles are caused by the decrease of the temperature. Water vapor and oil and gas are cooled to become water mist and oil mist, together with solid particles such as fabric fibers carried in the exhaust gas, Setting Machine are deposited as viscous grease on the inner wall of the equipment and piping.

The oil mist in the high temperature exhaust gas and the grease stained in the pipeline are flammable and explosive. The fabric fibers in the exhaust gas are likely to accumulate the packing or the filter evenly, resulting in the increase of the flow resistance of the pipeline equipment. Setting Machine Air static disturbances generated by the friction between the static electricity, but also lead to stereotypes often occur an important factor in fire accidents, affecting the safety of production and economic benefits.
