Reduction Of Emissions And The Future Of Pad Dyeing Production

　　 padding process It is an indispensable pre process technology in printing and dyeing. Shaoxing County once reached more than 200 production lines. Now there are only more than 60 production lines left in the county. Most of them are at a loss, or even a lot of them are in a state of shutdown. It has become a major concern for the production enterprises and Shaoxing County printing and dyeing Association.

　　 High sewage costs make enterprises single dare not answer.

A pad dyeing line at full load produces more than 200 tons of sewage per day, much lower than that of the ordinary printing and dyeing production line. However, the concentration of COD in the effluent produced by pad dyeing is as high as 5000-6000mg/L, and its sewage discharge cost is as high as 30-40 yuan per ton, which is 10 times higher than that of ordinary printing and dyeing and printing, which makes the cost of pad dyeing greatly improved.

At the same time, labor costs, dyes and other costs have also been raised. However, the cost of pad dyeing has not been increased because of the increase of production cost. When the river rises, the boat floats high " Before 2002, the processing cost per ton of pad dyeing was 4.5 yuan, and 10 years later, it dropped to around 2.2 yuan, and it was reduced by 1 times.

At the same time, the cost is greatly improved, while the other processing fee does not rise. awkward Status. It is understood that from 2009 onwards, Shaoxing County dyeing and finishing enterprises have a large number of shutting down, in just 3 years, from more than 200 production lines sharply reduced to more than 60.

　　 Nearly 40% of the pad dyeing line has been shut down.

"A pad dyeing line has invested at least about 10000000 yuan, and now all the 3 pad dyeing lines in the factory area have no choice but to turn off the electricity. They are not processing orders, but they can not afford to do so." The operator of a dyeing and printing enterprise in Shaoxing Binhai Industrial Zone felt very worried when he saw that his high padding line was discontinued, but there was no alternative.

The pad dyeing line in shutdown or half stop production is seen everywhere in Shaoxing dyeing and printing enterprises this year. According to incomplete statistics of the County printing and dyeing Association, there are more than 60 dyeing and finishing lines in Shaoxing County, which is the most concentrated place for pad dyeing production in the province, accounting for about 1/3 of the national pad dyeing line. More than 20 of them are currently in a state of discontinued production, accounting for about 30%.

"If this continues to develop, Shaoxing County pad dyeing line will be faced with" disappear. " Zhu Jianmin, President of Shaoxing printing and dyeing Association, told reporters that this will return to the plight of pad dyeing before 2002, which will definitely affect the development of printing and dyeing industry in Shaoxing county.

　　 The way out is to reduce emissions, raise quality and raise prices.

In printing and dyeing enterprises with pad dyeing, such as the high concentration of sewage discharge, closing the pad dyeing line becomes the preferred measure for enterprises to reduce pollution. Dyeing and finishing enterprises To be very careful This has aroused great concern of Shaoxing County dyeing and Printing Association. In recent days, Shaoxing County dyeing and finishing enterprises have been organized for many times. A meeting of the leaders of the major dyeing and dyeing enterprises has been held recently to explore the direction of survival and development of Shaoxing dyeing and finishing line under the condition of energy saving and emission reduction. "In energy saving and emission reduction, pad dyeing should survive and develop. Enterprises must solve the problem of high concentration of padding dyeing." The leaders of the participating enterprises have come to realize that enterprises need to improve quality and efficiency in order to promote price increase.

The fact of successful business proves that. Shaoxing second printing and dyeing factory is the "big cell phone" in Shaoxing county's pad dyeing production. When its peers lost a lot of money, the company maintained a good momentum of development. Chairman He Guojun told the secret: "research and development of new auxiliaries, develop high-grade products and achieve emission reduction at the same time, reduce the high concentration. This is the fundamental solution to the problem." It is understood that the company is currently developing new pad dyeing auxiliaries with 3 chemical dyestuffs, and has achieved good results. Shaoxing Qian Qing's male printing and dyeing is a leader in pad dyeing industry. Its processing cost is 25%-30% higher than that of its counterparts. Tian Jianhua, chairman of the board of directors, believes that pad dyeing has to go on the road of high quality and differentiation in order to survive and develop.

It is also understood that, under the urgent requirements of many printing and dyeing enterprises, the Shaoxing County printing and dyeing Association will carry out a collective price increase of pad dyeing processing fees, and is expected to formally increase the price in September.
