50 key technologies for tackling key problems

The outline puts forward 50 key technologies for energy conservation and environmental protection during the "12th Five-Year" period, including: 11 environmental protection fiber processing technologies, 17 new technologies for energy saving and emission reduction and dyeing and printing, 3 Advanced Treatment and resource recycling technologies, 4 industrial and textile energy-saving and emission reduction processing technologies, 2 waste textile recycling technologies, 10 new energy saving and emission reduction textile machinery, 3 environmental friendly dyestuffs, auxiliaries and slurry development projects.

The recycling technology of waste textiles includes the reuse technology of purified fiber and used textiles and the reuse technology of natural fibers and blended textiles.

Li Jinbao introduced the former mainly to study the biological modification and biodegradation of synthetic fiber materials, the recycling and utilization of fiber waste materials, and the development of textile waste recycling and reuse equipment and technology.

The latter is mainly to carry out research on the key technologies and related equipment of waste textiles recovery, cleaning, sorting, sorting and reuse.

This includes 6 technologies, including pure cotton fabric optimization, cotton opening technology, environmental protection and high efficiency bleach screening.

At present, a number of research institutes, colleges and enterprises in China have carried out a lot of work, and explored the recycling technology of textiles, rubber, metal clothing and other products.

The development and application technology of high efficiency and environmentally friendly dyes, auxiliaries and slurry includes three aspects: the development of degradable environment-friendly slurry, the development of high efficiency printing and dyeing dyestuffs and auxiliaries, and the development and application of low salt, low alkali and low temperature reactive dyes.

Li Jinbao introduced the first technology to study the structural design of deep denatured high performance modified starch and materials.

At present, domestic scientific research institutions have carried out relevant research and established the basic structure and composition of the new modified starch sizing agent.

The second technology needs to further solve three technologies: first, to develop dyes suitable for one bath dyeing of multi component fibers, two to develop cationic coatings, and three to develop soda additives, caustic soda, sodium sulfate, urea powder and urea.

At present, special Super dispersants have been developed in domestic universities to disperse liquid disperse dyes.

The third technology is to develop low salt, low alkali and low temperature reactive dyes with high dye uptake and high fixation rate.

At present, domestic enterprises have developed reactive dyes without salt dyeing process, so that the conventional five step process of rolling, drying and steaming of reactive dyes is simplified to three step process and comprehensive energy saving is 30%.

Advanced wastewater treatment and resource reuse technologies include advanced treatment of printing and dyeing wastewater, recycling technology of recycled water, clean wool production and lanolin recovery technology, hemp degumming wastewater treatment and comprehensive utilization technology.

Li Jinbao introduced that the first technology is to solve the problem of heavy water consumption and serious pollution in printing and dyeing process.

At present, the domestic membrane recovery device has been developed, which has made remarkable achievements in the early stage of turbidity and turbidity diversion, medium term recovery, and advanced biochemical treatment of cotton printing and dyeing wastewater.

The second technology is to study wool scouring process and sewage treatment technology, and to improve the lanolin recovery centrifuge.

At present, the vast number of enterprises based on the state environmental protection regulations, formulate standards, and gradually carry out cleaner production in worsted and woolen spinning industries.

The third technology is to solve the problem of waste water treatment technology and cost commonly encountered in the process of hemp degumming.

It is necessary to formulate corresponding technical plans for different hemp and different degumming methods, and make economic comparison and selection of various treatment technologies.

Vigorously promote 34 mature technologies

The outline puts forward 34 mature energy saving and environmental protection technologies during the "12th Five-Year" period.

These include 4 items: fiber cleaning production technology, 16 printing and dyeing, color woven clean production technology, 7 wastewater and waste gas emission reduction and treatment, recycling technology, 3 comprehensive utilization technology of resources, 1 processing technologies for environmental products, 3 new equipment with energy saving and emission reduction effects.

Li Jinbao introduced that polyester filament, staple fiber and masterbatch coloring technology belong to fiber clean production technology.

It is understood that the technology can shorten the production process, save the printing and dyeing links, realize environmental protection, energy saving, and promote clean production.

The membrane technology used for wastewater reuse is waste water, waste gas emission reduction, treatment and reuse technology.

This technology helps reduce the production of viscose fiber, and uses engineering membrane technology to treat wastewater. The recovery rate reaches 82.5%, and the desalination effect is good, which can meet the need of reuse.

At the same time, it can significantly reduce COD and BOD emissions. The effect is very good, and it also meets the need of reuse.

The development of one bath, multicolor, energy saving, environmental protection and high efficiency towels belongs to the processing technology of environmental protection products.

The technology uses the structure combination of different material yarns, and makes use of the principle of different dyeing rates of different yarns under different processing conditions, so that the fabric produces different color effects.

Due to short process, less supply and demand of equipment, electricity saving, water saving, steam saving and labor reduction, it can greatly reduce costs, enable enterprises to obtain high profits, and help reduce the difficulty of sewage treatment, energy saving and environmental protection.

The special energy-saving fan and dust filter system belong to new equipment with energy saving and emission reduction effect.

According to the introduction, the technology level of the equipment is close to the international level, which can effectively save energy and reduce the cost of users.

The goal of the promotion is to achieve 10 thousand units per year for spinning machine energy saving fans in 2015, 500 units per year for air-conditioners and 1200 units for dust filtering systems.

In addition, there are continuous fabric pretreatment equipment and continuous dyeing equipment. The automation, insulation and manufacturing quality of the dyeing and printing equipment are obviously improved. The new printing and dyeing production line has been equipped with home-made on-line detection and control equipment, equipped with wastewater reuse and residual heat recovery equipment, which can effectively reduce the consumption of steam and water by 20%.

The goal is to develop a new generation of high quality, high efficiency, environmentally friendly continuous fabric pre-processing equipment and continuous dyeing equipment by 2020, with an estimated annual sales of 40 sets.
