Scientific And Technological Progress Is The Driving Force For The Printing And Dyeing Industry.

"Printing and dyeing is not equal to pollution."

The overall development of the printing and dyeing industry has made more and more people realize this point and become the consensus of the industry.

To this end, the reporter interviewed Chen Zhihua, President of the China dyeing and printing industry association, and talked about the brilliant and "13th Five-Year" of the printing and dyeing industry in 12th Five-Year.

As an important part of the textile industry, the printing and dyeing industry in the "12th Five-Year" period has not only made great efforts in energy conservation, emission reduction and ecological civilization construction, but also made breakthroughs in technological progress and management innovation.

Facing the important development period of 13th Five-Year, the era of printing and dyeing industry as a scarce resource is coming. The industry should carry out its historical mission, not only to become a pioneer in the construction of ecological civilization, but also to create a new era of printing and dyeing industry with scientific and technological innovation.

Excellent performance of "12th Five-Year"

During the "12th Five-Year" period,

The overall operation is stable and stable, and the achievements in science, technology, management, energy conservation and environmental protection are obvious, and the operation of the industry has been balanced. "

Chen Zhihua said that during the "12th Five-Year" period, the printing and dyeing industry intensified its efforts to eliminate backward production capacity, popularized and applied advanced technology and equipment, reduced consumption, improved quality and efficiency, and promoted the pformation and upgrading of industries and structural optimization and adjustment.

"Especially in the case of lower production of printing and dyeing fabrics, the main economic indicators such as revenue, profit, export and investment of the industry have increased steadily, which fully shows that the overall level of China's printing and dyeing industry is constantly improving."

Scientific and technological progress is the driving force for the industry.

Chen Zhihua said: "during the" 12th Five-Year "period, the printing and dyeing industry accelerated the progress of science and technology, and the results of innovation were obvious.

Popularization and application; cold pad batch dyeing, small bath ratio dyeing, low salt and low alkali dyeing, chemical fiber and cotton blended fabric dyeing, one bath dyeing and other technologies have been widely applied. Inkjet printing has developed rapidly in the development of equipment, ink and products, and has made progress in such technologies as low foam dyeing, digital printing and dyeing process, on-line control and so on. The comprehensive utilization technology of resources such as condensate and cooling water reuse, reclaimed water reuse, mercerizing light alkali recovery, high temperature waste heat energy reuse, heat recovery of exhaust heat from stereotyping machine has been widely applied; less sludge biological treatment, ultrafiltration, nanofiltration and reverse osmosis membrane technology, biofilm reactor, magnetic levitation fan and other wastewater treatment technologies have been widely applied. During the "12th Five-Year" period, the efficient pretreatment and bleaching process, biological enzyme pretreatment, cold pad batch pretreatment, low temperature bleaching of cotton fabrics, and continuous flat width pretreatment of knitted fabrics were widely used in the printing and dyeing industry.

Moreover, during the "12th Five-Year" period, the management level of printing and dyeing industry has also been improved qualitatively.

Among them, meticulous management is further implemented, information management and technology are further integrated, and enterprise operation management and Internet technology are further integrated.

"With the popularization and application of three levels of measurement management, chemical control and ERP management, a large amount of information, fine and intelligent management has greatly enhanced the quality of the printing and dyeing industry and the efficiency of the enterprise, and provided the source protection for the green development of the industry."

Chen Zhihua said.

Eliminate backward production capacity and reduce development obstacles

The existence of backward production capacity is the main manifestation of the extensive economic development mode of the textile industry. It has become the main constraint to improve the overall level of the textile industry, accomplish the task of energy saving and emission reduction, and achieve sustainable development.

"Eliminating backward printing and dyeing capacity is conducive to the textile industry to reduce environmental pressure and maintain the sustainable development of the industry."

Chen Zhihua said that in recent years, the printing and dyeing industry has eliminated backward equipment and technology on a large scale, and the proportion of equipment and technology for energy saving, consumption reduction and environmental protection has gradually increased. The overall level of technology and equipment in the printing and dyeing industry has been significantly improved, not only increasing the added value of printing and dyeing products, but also saving resources and reducing pollution.

According to the statistics of the Ministry of industry and information, the printing and dyeing industry eliminated backward production capacity of 4 billion 189 million meters in 2010, eliminated backward production capacity of 1 billion 867 million meters in 2011, eliminated backward production capacity 3 billion 258 million meters in 2012, and eliminated backward production capacity of 3 billion 220 million meters in 2013.

Elimination of backward production capacity is evident.

Remarkable effect of energy saving and emission reduction

Chen Zhihua said that energy conservation and emission reduction is a long way to be adhered to in the printing and dyeing industry. Some achievements have been made during the "12th Five-Year" period, and "13th Five-Year" will continue to advance.

It is reported that the water consumption and energy consumption per unit product of the printing and dyeing industry in 12th Five-Year are obviously decreasing.

In 2010~2014, the water consumption per unit product of the printing and dyeing industry decreased by 28%, from 2.5 tons to 100 meters, to 1.8 tons / 100 meters, and the comprehensive energy consumption decreased by 18%, from 50 kilograms of standard coal / 100 meters to 41 kilograms of standard coal / 100 meters, and the water reuse rate increased.

During the "12th Five-Year" period, the repetition rate of water used in printing and dyeing industry increased from 15% to 30%, and the discharge of water pollutants decreased.

In 2010~2013, the total amount of waste water from textile industry dropped from 24.55 billion tons to 21.5 million tons, and the total amount of chemical oxygen demand dropped obviously, from 300 thousand and 600 tons to 254 thousand tons, and the ecological safety performance of products increased.

In addition, in recent years, the industry has perfected the inspection and supervision mechanism for the final product quality. Enterprises have actively carried out ISO9000 quality management system certification, ISO14000 environmental management system certification and Oeko-Tex100 certification. Many enterprises have passed the certification of ecological safety.

"Before 2003, China's export of textiles and clothing banned azo dye detection, the failure rate has been hovering around 15%, but in recent years, the overall failure rate of the project has dropped to less than 1.5%, is at the international leading level."

Chen Zhihua said.

Improving emission standards and encouraging enterprise development

Chen Zhihua pointed out that during the "12th Five-Year" period, the state's requirements for energy saving and emission reduction in the industry were getting higher and higher. The "comprehensive plan for energy conservation and emission reduction" in 12th Five-Year, the "printing and dyeing industry access conditions" and the "textile industry" 12th Five-Year "science and technology progress outline" and other documents all explicitly requested the printing and dyeing industry to develop circular economy, energy conservation and emission reduction, and promote the upgrading and pformation of the industry.

It is reported that in order to strengthen water pollution control in textile dyeing and finishing industry, in 2012, the Ministry of environmental protection and the State Administration of quality supervision, inspection and Quarantine jointly revised and issued the "GB 4287-2012" for textile dyeing and finishing industry.

In 2015, combined with the actual situation of textile parks and the adjustment demand of indirect emission control of water pollutants, a revised list of GB 4287-2012 for textile dyeing and finishing industry was issued (the Announcement No. 2015 of environmental protection department No. nineteenth).

The standard has raised emission requirements and formulated three emission limits. CODcr value of existing enterprises directly discharge 100mg/L and indirectly discharge 200mg/L; new enterprises directly discharge 80mg/L and indirectly emit 200mg/L (existing enterprises are also implemented according to this standard from January 1, 2015); sensitive areas directly discharge 60mg/L and indirectly discharge 80mg/L.

Tighten the emission limits of chemical oxygen demand, five day biochemical oxygen demand, suspended solids and ammonia nitrogen.

Tighten emission limits such as sulphides and aniline.

The index of adsorbable organic halide (AOX) is added.

Additional indicators of total nitrogen and total phosphorus were added.

Set the unit product baseline emissions.

"The improvement of emission standards is a challenge and pressure for printing and dyeing industry, and it is also an opportunity and a driving force.

During the "12th Five-Year" period, the printing and dyeing industry was forced by the national environmental protection policy to seize this historical opportunity and take the lead in the implementation of clean technology in the industry and strengthen environmental governance, so it enjoyed the fruits of pformation and upgrading earlier.

Chen Zhihua said.

Environmental protection work is fruitful.

"The printing and dyeing association regards the service industry as the top priority."

Chen Zhihua said that during the "12th Five-Year" period, the printing and dyeing Association continued to promote energy conservation, emission reduction and green environmental protection.

The association regularly launches the selection and evaluation work of the national recommended catalogue for energy saving and emission reduction in the printing and dyeing industry every year. At the same time, the recommended advanced technology has been released on the annual environmental protection annual meeting. So far, the nine batch of 246 advanced, mature, practical and effective technologies has been launched, which has been reconsidered by the industry and has achieved remarkable energy saving and emission reduction effects in the enterprise.

The ten annual environmental protection annual meeting, held in 12th Five-Year, has been well received by the vast number of printing and dyeing enterprises and related enterprises.

The association also organizes on-site promotion activities for key technologies, and carries out skills training in energy saving and emission reduction for employees, and sets up a strategic alliance of environmental protection technology Specialized Committee, textile wastewater treatment and recycling industry in the textile and dyeing industry, and carries out special research and consultation on energy saving and environmental protection in printing and dyeing industry.

"13th Five-Year" heads up to sail

During the "13th Five-Year" period, China's printing and dyeing industry will further develop.

At present, the printing and dyeing industry is in a critical period of structural adjustment, pformation and upgrading. Environmental constraints have increased, which has increased the burden on enterprises, but on the other hand, it has positive significance for strengthening industry self-discipline, reducing structural overcapacity and reducing the difference between environmental costs and inputs. It is also an opportunity for printing and dyeing enterprises, especially for the entire printing and dyeing industry.

Have problems and face it calmly.

Chen Zhihua said that during the period of "12th Five-Year", the printing and dyeing industry has made great progress, and the problems still exist, which will be solved or mitigated in the period of "13th Five-Year".

Among them, the aggravation of enterprise differentiation is limited by the strength of capital, technology, talent and management. The ability of small and medium enterprises to enhance their development is obviously insufficient, and the survival dilemma is increasingly prominent. The requirements and standards of the state in eliminating backward production capacity and reducing total pollutant discharge are constantly improving.

Still faced with multiple pressures, such as shortage of funds and insufficient technical support, the level of energy conservation and emission reduction has been restricted. The cost of printing and dyeing enterprises has been rising. Besides the labor cost, the rise of environmental costs has irreversibly increased the burden on the industry. The ecological requirements of the textile market in Europe and the United States have been increasing and the index has been increasing, which demands higher production and product safety for printing and dyeing enterprises.

These problems need to be taken seriously.

The next stage of development is clear.

The printing and dyeing industry will intensify its industrial structure optimization and pformation in the '13th Five-Year' period.

Scientific and technological progress, management innovation, energy conservation and emission reduction will be carried out in a purposeful and planned way.

Chen Zhihua said.

It is reported that "

During this period, the printing and dyeing industry will accelerate the optimization of industrial structure and the pformation and development of enterprises.

Specific directions include: sample production to product design, self research and development pformation; raw material processing to self trading and brand building pformation; resource consumption to energy conservation and emission reduction pformation, highly concentrated to moderately balanced development.

The growth of main business revenue and profit also indicates that the industry is changing from quantity scale to quality benefit.

At the same time, efforts should be made to improve the printing and dyeing industry's technical level.

For example, to improve product quality and energy saving technology, we should use ecological safety, high efficiency auxiliaries, new dyes with high absorption rate, automatic digital equipment and intelligent management system.

Management innovation of printing and dyeing industry will also improve operation level in 13th Five-Year.

Meticulous management is further implemented; information management and technology are further integrated; enterprise operation management and Internet technology are further integrated.

In addition, energy saving and emission reduction will also become the competitive advantage of the industry and enterprises during the "13th Five-Year" period.

The technology of high standard, low cost and three wastes will be improved continuously, and the level of three levels of measurement and cleaner production will also be improved.
