During the "11th Five-Year" period, the textile industry accelerated the progress of science and technology as an important support for promoting the adjustment and upgrading of industrial structure. A series of new technologies for energy saving and emission reduction were developed and applied in the industry, and achieved remarkable results.

According to the data released by the China Textile Industry Association, during the period of 11th Five-Year, at comparable prices,

Spin

The comprehensive energy consumption of the added value of industrial units has decreased by about 40%, and the total volume of sewage discharge has dropped by more than 40%.

The development and manufacturing capabilities of green environmental protection equipment have created a good foundation for the textile industry to achieve energy conservation and consumption reduction.

The development and popularization of energy saving motors in cotton spinning industry further reduce the energy consumption per ton yarn. The application of air conditioning automatic control technology can reduce the air conditioning energy consumption by 10-15%.

The chemical fiber industry promotes the application of differential direct spinning and other practical energy-saving processing technologies. The application of the new melt direct spinning heat medium heating system reduces fuel consumption by nearly 1/3.

The efficient short flow pre-treatment technology in printing and dyeing industry has been applied to all kinds of fabric dyeing, which can reduce the consumption of electricity, steam and water by more than 30%. Cold pad batch dyeing has been applied to medium thick fabrics, and it can save steam 40%.

Progress has been made in water-saving work in the textile industry.

During the "11th Five-Year" period, the fresh water consumption of printing and dyeing industry 100 meters dyeing and printing cloth decreased from 4 tons to 2.5 tons, and the total water consumption decreased by 37.5%.

Printing and dyeing cloth

The water reuse rate of production increased from 7% to 15%, increasing by 8 percentage points.

The application of advanced equipment and technology such as high efficiency short flow pre-treatment and continuous dyeing equipment, new batch dyeing machine, cold pad batch dyeing and biological enzyme desizing can achieve more than 20% water saving.

Pollutant reduction and control have achieved results.

The printing and dyeing industry has developed a new technology for deep treatment and reuse of the separated and separated wastewater, so as to achieve the goal of stabilizing wastewater treatment and reduce the discharge of sewage.

The deep purification and recycling technology of silk reeling wastewater has been applied in large and medium-sized silk reeling enterprises. The recycling rate of silk waste water can reach more than 90% and basically achieve zero discharge of sewage.

Chemical fiber industry uses membrane filtration, activated carbon adsorption, waste gas and sulfuric acid technology to control viscose wastewater and exhaust gas, effectively reducing pollutant emissions and improving the level of cleaner production in the industry.

Recycling of resources is continuously improving.

At present, domestic regeneration

fibre

Production capacity reached 7 million tons and output reached 4 million tons.

Recycled polyester fiber recycling technology has been widely promoted, and technology continues to upgrade. Regenerative spinning technology not only develops three-dimensional hollow fibers for home textile filler, but also breaks through long and short differential fiber and medium strength industrial yarn, and is being further promoted and applied.

The textile industry has continuously improved its ability to develop textile fiber materials using natural fast-growing forest products, and the industrialization of bamboo pulp fiber and hemp fiber has been realized.

New technologies such as condensate and cooling water reuse, waste heat recovery, reclaimed water reuse, mercerizing light alkali recovery and other comprehensive utilization technologies have been vigorously promoted and applied in the industry, thus greatly improving the efficiency of water, heat and other resources.
