The textile industry is growing rapidly, energy conservation and environmental protection are urgent

The new environmental protection law, known as the "strictest in history", was officially implemented on January 1, 2015. The textile industry is under increasing constraints in energy conservation and environmental protection. According to the new regulations, the chemical oxygen demand (COD) of textile enterprises The direct emission needs to be controlled at 80 mg / L. since the COD direct emission standard was raised to 100 mg / L in 2013, the sewage discharge threshold of the textile dyeing and finishing industry has been raised again, and the environmental protection curse on the textile industry has become tighter and tighter. After the rapid growth of the textile industry in previous years, major changes have taken place in resource endowment conditions such as labor, land and market, increased resource and environmental constraints, and labor With the rising cost of other factors, the development mode of high input, high consumption and quantity expansion has been unsustainable. In addition, the new environmental protection law known as the "strictest in history" was officially implemented on January 1 this year, and the constraint pressure on energy conservation and environmental protection in the textile industry is increasing. According to the new regulations, the chemical oxygen demand (COD) of textile enterprises is increasing The direct emission needs to be controlled at 80 mg / L, which is that after the COD direct emission standard was increased to 100 mg / L in 2013, the pollution discharge threshold of the textile dyeing and finishing industry has been raised again, and the environmental protection curse on the textile industry is getting tighter and tighter.

The source of energy conservation and environmental protection lies in textile machinery equipment. The optimization and innovation of textile machinery technology is the premise to drive the overall improvement of the whole textile industry chain. With the concept of environmental protection gradually rooted in the hearts of the people, textile machinery has greatly improved in energy conservation and environmental protection.

Spinning equipment is gradually developing in the direction of large winding, short process, automation and continuous production. Both single machine and complete set of equipment are focusing on improving quality, reducing cost and increasing efficiency. Among them, the cost reduction effects of spinning collective doffer coarse and fine connection, fine connection, high-speed energy-saving spindle, air conditioning dust filtering equipment, new spinning forms and motor system are remarkable, one by one It has gradually become a hot spot in the market. As an important index reflecting the economic performance of weaving equipment, there is no doubt about the importance of energy saving. In order to reduce the compressed air consumption required for weft insertion, many looms adopt modular design, which not only improves the compactness of structure and the convenience of operation, but also reduces the maintenance cost of equipment to the greatest extent

Based on the large-scale, continuous and flexible development in previous years, the development trend of seven fiber mechanical equipment has gradually developed towards refinement and energy conservation. Foreign textile machinery manufacturers have paid early attention to energy conservation, environmental protection and sustainable development of products. Eurekon chemical fiber launched the e-save energy-saving logo for its energy-saving systems, equipment and components as early as 2004 and established the e-save energy-saving concept In recent years, e-save has interpreted the concept of comprehensive energy efficiency and emphasized the important role of eurekon chemical fiber in sustainable development. At home, textile machinery enterprises have gradually begun to pay attention to it in recent years and achieved good results. The per ton fiber consumption of polyester staple fiber equipment of Hengtian Flour Industry Co., Ltd. has reached the domestic and even international advanced level: power consumption of 145 kwh, Steam consumption is as low as 750 kg, desalted water consumption is less than 0.61 m3, cooling water consumption is 51 m3, refrigeration consumption is less than 25 m3, and industrial water consumption is 0.6 m3.

The printing and dyeing industry is a high energy consumption, high water consumption and high pollution industry. In today's situation, energy saving, emission reduction, clean production and reuse of water resources are very important issues. Pre processing equipment for dyeing and printing mainly focuses on water saving, steam saving and emission reduction technologies and products, including hot alkali mercerizing, ultrasonic washing, foam treatment, chemical detection and distribution, wastewater reuse and waste heat recovery. The technology and device will be further developed and applied. The finishing equipment adopts anhydrous processing technology, plate making printing technology, low-temperature plasma treatment technology, electrochemical technology, nanotechnology, biological enzyme technology, etc., so as to make the printing and dyeing finishing process shorter, higher production efficiency, better product performance, more environmental protection and energy saving. In terms of printing machinery, the digital printing machine has no sewage Emissions, in line with the requirements of environmental protection and energy conservation, continue to maintain high-speed growth, and the printing speed is further accelerated, the cost is further reduced, and the market recognition is higher and higher. The flat screen printing machine is continuously improving in improving the production speed and meeting the printing of heavy fabrics, and alleviates the pressure of labor shortage and rising labor cost through some machine type transformation and upgrading. The round screen printing machine continues to To develop in a more accurate, efficient, practical and convenient direction, in general, we must further develop new printing and dyeing equipment with a high degree of automation, and further study the technologies and equipment to reduce energy consumption and wastewater discharge; study the rapid desizing technology of woven fabrics, ultra sonic washing technology and low bath ratio intermittent dyeing technology; overcome the difficulty of saving 50% water in continuous scouring and bleaching of knitted fabrics Guan: change the current situation of low occupancy and lagging development of new wool fabric dyeing and finishing equipment.

This year is the closing year of the 12th Five Year Plan. Cost reduction and efficiency increase, energy conservation and environmental protection are the core contents of the 12th Five Year Plan of the textile industry. China's textile machinery enterprises have paid much more attention to energy conservation and environmental protection performance than before, but they are relatively concentrated in the production process and have not fully covered all links of the whole production chain. If the industry wants to have a great leap forward development, it must be further innovated Energy saving and environmental protection technology, develop energy saving and environmental protection models, and let the concept of energy saving and environmental protection penetrate into every link of industry development
