Japan Refine Synthetic Leather Processing And Bid Farewell To Organic Solution

The processing industry not only uses a lot of water resources, but also uses a large amount of chemicals such as dyes and auxiliaries.

Therefore, under the background of high energy consumption and high pollution industries in the world, how to realize the development of enterprises under the premise of protecting the environment is an inevitable problem for dyeing and finishing enterprises.

The characteristics of dyeing and finishing industry determine that environmental protection needs more efforts than other textile enterprises, such as carefully selecting raw materials and dyes, reducing environmental load on factories, ensuring the health and safety of employees, safety and environmental protection of finished products and so on.

It can be said that dyeing processing calls for a comprehensive environmental protection strategy.

From the point of view of dyeing processing, environment-friendly materials can be roughly divided into four categories: one is the processing technology that does not use organic solvents in the production process; the other is the production technology and technology to reduce environmental load; three, the textile materials that are conducive to environmental protection; and the four is the development of environment-friendly products. Three.

At present, the 3 largest dyeing and finishing enterprises in Japan, such as Komatsu scouring, dyeing workers in the East China Sea and Seiren, are striving to achieve "eco-friendly and environment-friendly" production.

Komatsu scouring company focused on environmental protection as a key issue of enterprise management. In 1999, the declaration of "Komatsu scouring environmental management" was published, and the corresponding environmental protection measures were implemented in each 5 year medium term plan from 2000.

In the second round of environmental protection plan in 2004, measures were also put forward to reduce emissions of organic solvents, promote the recycling and reuse of waste resins, enhance technological development and reduce waste emissions.

The East China dyeing company has changed the fuel used by all factories in Japan to biochemical materials.

It is estimated that only this one can reduce greenhouse gas emissions by 50 thousand tons per year.

At the same time, the company also made efforts to reduce the emissions of harmful mud. The amount of harmful mud discharged in 2007 has decreased to 10% in 2005.

On the basis of studying the relevant regulations on the restrictions on the use of chemicals at home and abroad, Seiren has identified 372 kinds of chemicals that stop using and restricting their use.

In order to solve the problem of soil damage caused by waste water, the company has also worked out a solution with the dyestuff manufacturers.

At the same time, the company is also actively developing new materials which are less burdens on the environment.

Recently, Seiren has successfully developed the technology of easy decolorization of polyester fibers, which is beneficial to the recovery and reuse of polyester fibers.

In addition, the company's technical pformation in the production of synthetic leather and synthetic leather has also been completed, marking the processing of synthetic leather and synthetic leather will thoroughly bid farewell to organic solvents.
