Industrial characteristics of the textile industry
The raw materials of textiles mainly include cotton, cashmere, wool, silkworm cocoon silk, chemical fiber, feather, feather and so on.
The downstream industries of the textile industry mainly include the garment industry, home textiles, and industrial textiles.
According to statistics from the State Environmental Protection Administration, the total amount of sewage discharged from the printing and dyeing industry ranks fifth in China's manufacturing emissions. 60% of the industrial wastewater discharge also comes from the printing and dyeing industry, and the pollution is heavy, the processing is difficult, and the reuse rate of wastewater is low. Chemical fiber industry in the production process, some products use a large number of acids and alkalis, and ultimately produce sulfur, sulfuric acid, sulfate and other harmful substances, causing serious environmental pollution; some are the solvents used, the media more serious environmental pollution. Another manifestation of environmental pollution caused by chemical fiber production is the non-degradability of chemical fiber products. In particular, synthetic fibers have high waste recycling costs and contaminate air after combustion; they are not easily degraded after being discarded and cause deterioration of the soil environment. In addition, the pre-treatment process of the wool and linen industry is also the focus of industrial wastewater discharge. In terms of energy consumption, the power consumption of textile machinery and chemical fiber machinery is very prominent. The total energy consumption of the chemical fiber industry is about 10%-30% higher than the advanced level in foreign countries.
