Zero Discharge Of Sewage Is A Difficult Problem In Printing And Dyeing Industry.

To achieve zero discharge of sewage is a difficult problem for the printing and dyeing industry to overcome. < p >

After more than 5 years of experimental research, Wujiang Yi Rui textile finishing Co., Ltd. broke through the bottleneck of a href= "http:// www.sjfzxm.com/news/index_c.asp" > sewage less than /a > zero emission yesterday, and built up a physical environment less than atmospheric pressure, and through the extraction of real air anti absorption technology, 100 thousand meters of printed fabric without a little waste water discharged, so as to achieve the goal of zero discharge of sewage.

< p > > a href= "http://? Www.sjfzxm.com/news/index_c.asp" > printing and dyeing > /a > experts believe that this technology has been the first to achieve permeation printing without water treatment in the whole country. It not only improves printing technology to a new height, fills the gap of domestic printing and dyeing industry, is suitable for mass production, but also wins higher social benefits for enterprises, saves valuable water resources, and makes a model for the protection of ecological environment.

< p > printing and dyeing wastewater treatment has always been a key and difficult point in the environmental pollution control in Wujiang district.

A few years ago, Gu Mingwei, chairman of the company, went to France to take part in the international fabric exhibition. He found that this technology of permeation printing in Germany has been applied in Shengze, Shaoxing and so on because of its high entry threshold, and is still in a blank state in China.

< /p >

< p > and the highlight of this < a href= "http:// www.sjfzxm.com/news/index_c.asp" > < /a > is that it can save a lot of water resources and greatly improve the dye permeability, prevent the fabric from appearing some whiteness and whiteness in the sewing process, and at the same time, the color fastness and printing quality of the fabric are very high.

< /p >

< p > Gu Mingwei thinks that as a small printing and dyeing enterprise, only by increasing the R & D of science and technology can the development road be changed.

If we can break through this osmotic printing technology, we can not only improve the quality of fabrics, but also save energy and reduce emissions and save water resources.

Based on this thinking, Gu Mingwei decided to develop this osmotic printing technology himself.

< /p >

< p > to see the market, Gu Mingwei immediately set up a R & D team and invested about 3000000 yuan to develop "negative pressure vacuum printing" technology.

After more than 5 years, referring to Germany's advanced technology, combined with the permeability of water printing and the fine process of conventional heat pfer, a series of technical and technological problems have been conquered after hundreds of small sample tests.

< /p >

< p > by using the technology of negative pressure vacuum printing, the color fastness of fabrics can be better, the handle is soft and comfortable, the gloss is seductive, and the penetration effect is similar to that of water printing. However, the cloth surface is richer and more visual than the water printing, especially the process is short, the quality is high, and the fabric products are pformed into "high, fine and special".

< /p >

< p > Gu Mingwei said that with the increasingly serious environmental situation, reducing pollutant discharge has become a must for printing and dyeing enterprises. Enterprises are obliged to take responsibility for environmental protection.

According to the conventional water printing technology, thousands of tens of thousands of tons of water need to be consumed every day. As a result of this scientific research, it can save 1600 tons of water, improve efficiency and reduce the waste of resources by printing 100 thousand meters of fabric a day.
