Wujiang Private Enterprises Break Through The Problem Of Energy Saving And Emission Reduction In Printing And Dyeing Industry

< p > printing and dyeing finishing is a high water consumption and high pollution industry. It is the focus of national energy conservation and emission reduction.

A new negative pressure vacuum printing technology developed by Yi Rui textile finishing Co., Ltd., Shengze, Wujiang, not only achieves zero discharge of printing and dyeing wastewater, but also has a 30% higher color fastness than conventional printing, and a richer and finer fabric color.

< p > in the printing and dyeing industry, the conventional heat pfer printing has a history of over 20 years.

However, under the technical conditions, when using this method, the dye color only stays on the surface, and can not penetrate into the fiber, resulting in serious color difference between the positive and negative sides of the fabric.

Water printing can solve the problem of dye permeability very well, but a large amount of wastewater and sewage will be produced during printing and dyeing.

Taking ordinary Chiffon as an example, 16 tons of printing and dyeing wastewater will be produced by water printing every 1000 meters.

< p > > for this reason, < a href= "http:// www.91se91.com/news/index_c.asp" > Yi Rui spun < /a >. Based on the traditional heat pfer and water printing, the negative pressure vacuum printing technology has been innovating and developed to solve this problem.

Gu Mingwei, chairman of Yi Rui textile, said that the technology first appeared in Germany, but was limited by high equipment prices and had not been applied in China.

The negative pressure vacuum printing technology developed by Yi Rui is entirely based on domestic equipment, and the machine structure has been improved.

< /p >

< p > "after careful study, we found that the core technology of the equipment originated from Germany was to add a vacuum device in the roller.

However, it is very difficult to complete heating and vacuuming in a roller. "

Gu Mingwei, who had a strong interest in machinery, decided to bite off this hard bone.

In the past 7 years, he led the technical team into the workshop and spent about 3000000 yuan. After thousands of experiments, he finally got through the difficulty.

< /p >

< p > "small businesses are restricted by capital and talent, so it is hard to do research and development.

But the new technology and new technology are the key to enhance the core competitiveness of the enterprise. "

Gao Wenzhen, general manager of Yi Rui textile, said that the reverse permeability of printed cloth is an important index in the printing and dyeing industry.

< /p >

< p > through negative pressure vacuum printing, the dye and fiber can be fully integrated in vacuum, achieving good permeability of water printing and achieving fine and rich effect of conventional heat pfer printing.

More importantly, the production process is simple and realizes zero discharge of printing and dyeing wastewater.

< /p >

< p > at present, the negative pressure vacuum printing technology developed by Yi Rui textile has been mass produced, with a daily output of 15 thousand meters, and the printing quality of 100 thousand meters printed material is up to 98%.

Eugen yarn, 420 polyester taffeta and chiffon printing are all the highlights of this year.
