During 12th Five-Year, demand for knitwear will continue to grow at home and abroad.

　　 Knitting industry The increase of development volume is no longer the key point, and the promotion of quality is the key to development.

Facing the adverse effects of the complex international economic environment and many uncertain factors on the development of the industry, the knitting industry will adhere to the strategy of technology, brand, sustainability and talent.

By improving workers' operation level and improving labor productivity, it is the key to upgrading the industry.

In recent years, the price of raw materials has fluctuated greatly, the international debt crisis has been frequent, domestic money has been tightened, labor, land prices, energy and logistics prices have been rising. These factors are more stressful for textile and garment manufacturing industry. How to survive, compete and achieve sustainable development in such an environment is undoubtedly an important issue facing the Chinese textile and garment industry.

Reporter: what are the general measures for the sustainable development of the knitting industry during the "12th Five-Year" period?

　　 Guang Xing Lin From the aspects of low carbon, energy saving and green environmental protection, the knitting industry must improve the equipment and technology in accordance with the requirements of the printing and dyeing industry, the introduction of the printing and dyeing industry, the water metering method and the basic norm of unit consumption and so on, and promote the new technologies of energy saving, emission reduction, clean production and recycling of resources, so as to implement energy saving and low carbon projects and achieve sustainable development.

Combined with the characteristics of the industry, we should improve the standard and standard system for sustainable development. We should develop energy consumption standards for designated products, improve the standard system of cleaner production, improve the quota of water intake, and promote relevant standards at home and abroad, such as environmental management system and energy management system standard, so as to enable enterprises to strengthen energy consumption control and to focus on pollution prevention in the whole process of production.

To encourage knitting enterprises to adopt advanced technology and management, greatly improve energy efficiency and environmental protection in weaving, pretreatment, dyeing and printing, finishing, finishing, waste water and waste gas treatment, on-line monitoring and automatic control. We should popularize advanced technology and management mode through comprehensive, professional meetings and expert on-site guidance. The industrial clusters should be classified and directed, and the public service system of energy conservation, environmental protection and circular economy should be strengthened. We should carry out the demonstration projects to publicize the outstanding enterprises in environmental optimization, energy conservation and emission reduction, and advanced enterprises of cleaner production, and comprehensively promote advanced experience. Advocating sustainable development mode of production and life style.

Reporter: what are the specific requirements for knitting enterprises in green environmental protection during the "12th Five-Year" period?

Lin Guangxing: there are still a lot of work to do in this area, and we must continue to push ahead. The first is raw materials. Expand the application of non cotton fiber in knitting production, such as various kinds of natural fibers, such as bast fiber, using Imitation cotton chemical fiber, using chitin, seaweed fiber and other new fibers to promote product development, and use high-strength polyester filament to promote the development of warp knitted products for industry. Diversification of raw materials makes the industry's dependence on cotton fiber gradually reduced.

Technical aspects. The technology of flat fabric washing, air flow dyeing, digital continuous mercerizing, cold pad batch pretreatment, enzyme refining, digital printing, etc. For example, the first is cold pre processing technology: it can increase production capacity by 30%, reduce steam consumption by 85%, reduce water consumption by 65%, and reduce COD by 50%. Two is the air flow dyeing technology: the high temperature and high pressure airflow dyeing technology is compared with the traditional overflow jet dyeing technology. The same fabric can usually save electricity by about 30%, and save 60% of the auxiliaries (salt and alkali). The bath is relatively small, saving more than 50% water, saving steam 50%, and dyeing time by 15%. The three is the plain wash technology of knitted fabric: compared with the traditional technology, it usually saves 67%, saves 40% of steam and saves 30% of auxiliaries. The four is the application of biological enzyme in dyeing and finishing: reduce energy consumption and water consumption, and improve the cleanliness of wastewater. Using only one process step (bleaching) to replace the chemical preparation with enzyme, the water consumption per ton of knitted fabric is reduced by more than 20 tons, and the fabric feels soft. The five is digital printing: it usually reduces power consumption by 50%, reduces water consumption by 30%, and reduces dye consumption by 60%. No net sizing, no flower back and color limit, suitable for multiple varieties, small batch requirements.

Reporter: what are the specific measures and recommendations for energy conservation?

　　 Guang Xing Lin We must comprehensively establish the concept of energy conservation, enhance the awareness of energy conservation, and establish the application of technological transformation and advanced technology to achieve energy saving and environmental friendliness. The main measures are the implementation of energy-saving lamp project, solar collector project, ground source heat pump, and system energy saving transformation in power, steam, air conditioning and building.

First is the ground source heat pump. The ground source heat pump central air-conditioning system is more energy efficient than the traditional air conditioning system 50%~75%. No discharge of waste, low noise and water saving; one machine can be used for many purposes, heating, heating and cooling; safe in use, reliable in performance, long life in the unit, and low in operation and maintenance costs. The second is solar energy. Solar energy is the most abundant clean energy available to mankind. Solar energy is used to warm up production and domestic water, reduce steam consumption, reduce carbon emissions, low operating cost, low noise of generating units, no pollution to the environment, no impact on atmospheric environment, and good economic and social benefits. Finally, the "LED" energy saving lamp. To popularize the "LED" energy saving lamp in the industry, it has the advantages of high luminous efficiency, less power consumption, long life and easy maintenance, so as to achieve the goal of low carbon emission reduction.

Reporter: what are the specific measures for recycling and recycling of resources?

Lin Guangxing: mainly the application of recycled fiber in knitting production, dyeing and finishing waste heat recovery, printing and dyeing wastewater treatment and reuse.

First of all, the application of recycled fiber yarn in knitting production. We must persist in the idea of using renewable resources to protect the environment, and expand the application of recycled fibers in the development of knitted products, develop new products, and promote the recycling of fiber resources. Secondly, dyeing and finishing waste heat recovery. During dyeing and finishing of knitted fabrics, waste gas and waste water are produced. A large amount of heat energy is dissipated to the atmosphere and water with waste gas and waste water. It is imperative to recover waste heat. The waste heat recovery equipment carries out heat exchange between high temperature waste gas and waste water through heat exchanger and fresh air and clear water to form hot gas and hot water for production. Third, the treatment and reuse of printing and dyeing wastewater. The technology of physical, chemical and biological comprehensive treatment, composite functional resin adsorption, biological contact oxidation and membrane technology were used to treat wastewater, so that the reclaimed water could be reused after treatment.
