< p > according to relevant reports, the pollutant discharge standard of synthetic leather industry will be upgraded, and the new standard is expected to be released in the year.

< /p >

< p > analysts believe that the new standard will refer to the experience of the integration of Wenzhou synthetic leather industry, and the requirements of some indicators will be more stringent.

At present, the synthetic leather industry has overcapacity and slump. It is expected that environmental constraints will limit the overall operating rate of the industry, and the profitability of the leading enterprises is expected to improve.

< /p >

< p > analysts say many of the sub industries of < a href= "http://www.91se91.com/news/index_c.asp" > chemical industry < /a > have excess capacity. By implementing more stringent environmental protection measures, they can quickly go to production capacity and improve the profitability of the industry.

In glyphosate, printing and dyeing industries, this logic has been confirmed, and the synthetic leather industry is also expected to confirm this logic once again.

< /p >

< p > data show that artificial leather, < a href= "http://www.91se91.com/news/index_c.asp" > synthetic leather product < /a > is an alternative material for natural leather, made up of two parts: leather cloth (woven cloth, non-woven fabric) and coating resin. According to material and technology, it is divided into PVC synthetic leather, PU synthetic leather and superfine fiber PU synthetic leather.

PVC artificial leather, as the first generation of artificial leather, is added with plasticizer DOP and stabilizer containing heavy metals such as lead and cadmium. It is difficult to degrade. It is easy to cause pollution to the environment. It has been banned in developed countries, and is also gradually replaced by PU synthetic leather in our country.

< /p >

< p > at present, the synthetic leather market in the world is mainly made of PU synthetic leather, and the super fine PU synthetic leather with better performance is developing rapidly.

PU leather and microfiber PU leather need to use PU slurry as coating resin, PU slurry using DMF as solvent, and PU leather dry / wet process production process all use DMF, so DMF exhaust emissions become one of the main pollution in the industry.

This is also the reason why the a href= "http://www.91se91.com/news/index_p.asp" > Wenzhou < /a > remediation plan has made special targets for DMF air concentration.
