Lishui Opens The Pformation And Upgrading Of Synthetic Leather Industry

< p > in the upper reaches of Wenzhou, Zhejiang, the capital of China's synthetic leather, Lishui is famous for its beautiful scenery and beautiful scenery.

Because of its convenient proximity to Wenzhou, synthetic leather has also become a pillar industry in Nanshan District City, Western Zhejiang.

While Wenzhou is actively improving the traditional synthetic leather industry, Lishui has opened up a new path for the pformation and upgrading of the synthetic leather industry.

Recently, the first demonstration base of aquatic eco synthetic leather was officially settled in Lishui.

Less than 10 years ago, the investment promotion work of the Lishui Economic Development Zone in the construction of P was in full swing. Relying on its geographical advantages close to Wenzhou, and the impact of the synthetic leather industry on the water environment was relatively small, many Wenzhou synthetic leather enterprises settled here.

< /p >

< p > at present, there are 27 synthetic leather enterprises in the Development Zone, 12 in leather base enterprises, 17 in synthetic leather post-processing enterprises, 3 in color auxiliaries, 7 in resin raw materials enterprises, and in other than 1000 processing units in. The annual production of synthetic leather is about 500 million square meters.

The total output value of synthetic leather and its supporting enterprises in the development zone increased rapidly from 1 billion 400 million yuan in 2004 to 14 billion 700 million yuan in 2012, accounting for more than half of the industrial output value of the development zone.

The number of synthetic leather household in the Development Zone accounts for 6.4% of the whole country, and has become a fast growing and high industrial agglomeration zone in China.

However, with the continuous expansion of synthetic leather production capacity and the deepening of industrial development, the negative impact of industrial development is also gradually emerging: as traditional synthetic leather uses oil-based polyurethane resin to produce synthetic leather surface and base materials. In production, toxic and harmful organic solvents such as DMF (two methformamide) and toluene are needed, which are volatile in the production process and become organic waste gas, causing air pollution.

Therefore, these oil-based solvents become the main source of pollution.

< /p >

< p > starting from the introduction of synthetic leather industry, the Lishui Development Zone will guide the synthetic leather enterprises to work hard in the aspects of product structure and cleaner production, so as to help enterprises realize terminal treatment and recycle organic solvents in waste gas and waste water.

< /p >

< p > < strong > terminal treatment and simple shutting down are not desirable. The innovation of production process is helpful to solve the problem from the source < /strong > /p >

< p > "we can not simply grasp the terminal governance, and we can not shut down businesses one by one. We need to innovate ideas, policies, platforms, technology, materials and so on.

Chen Jingfei, director of the Lishui eco industrial agglomeration area (Economic Development Zone) management committee, told reporters that the pformation and innovation of the synthetic leather industry is the top priority of Lishui's industrial pformation and upgrading.

< /p >

< p > 2005, the Development Zone Management Committee captured the relevant information of waterborne resin in the production of whole leather.

Waterborne resins, which contain no organic solvents, are clean and environment-friendly. They are effective measures to control pollution at source.

Since then, they have been tracking the development of waterborne resins for synthetic leather, and organized enterprises in the development area to try to replace water-borne resins with polluting oil solvents.

< /p >

< p > some enterprises have begun to explore the process reform spontaneously.

Zhejiang resistant & amp; Industrial Co., Ltd. is one of the earliest synthetic leather enterprises in the development zone.

As early as 2006, enterprises took the lead in trying out water-based resin production line in development zones.

Ying Jianguo, chairman of the company, introduced that in 2006, due to the high demand for some products, the company began to try to introduce waterborne resins as raw materials.

< p > < --EndFragment-- > over the past few years, the development zone has issued the notice on the ecological pformation of synthetic leather enterprises and the notice on the compulsory promotion of waterborne resins in the enterprises after the synthetic leather.

In 2010, the Lishui municipal government and Bayer materials technology (China) Limited signed a framework agreement on waterborne synthetic leather resin, which supported the construction of Lishui water-based eco synthetic leather production line.

In 2011, the Development Zone issued a number of opinions on the promotion of the use of synthetic leather waterborne resins, from macroscopic guidance to the environmental protection reform of the synthetic leather industry in the development zone.

< p > < strong > how to overcome the technical difficulties? The park should build public technology platform and do well technical services < /strong > /p >

< p >, however, it is difficult to change "leather".

Immature technology has become the first difficulty for enterprises to encounter, and high technology pfer price and raw material price are second difficulties.

< /p >

< p > to this end, the development zone has set up a public technology service platform for synthetic leather.

In 2010, China's research and development center of water based ecological synthetic leather was established in the development zone.

In May 2012, 10 research institutes and enterprises, such as the relevant schools in the Development Zone, the Lishui Quality Inspection Institute, and the Lishui Nike water resin technology Co., Ltd., formed the Zhejiang eco synthetic leather industry technology innovation strategic alliance.

Nike also joined the Anhui University, Shaanxi University of Science and Technology and other institutions to form the Lishui Xinke eco Synthetic Leather Research Institute, integrating technology resources, and in-depth research and development of waterborne resins and synthetic leather products.

< /p >

< p > 2010, < a href= "http://www.91se91.com/news/index_p.asp" > Lishui < /a > City Nike Nike joint related company unveiled at the international exhibition of Lang Pei Li, and put forward the concept of "zero DMF" eco synthetic leather for the first time in the field of synthetic leather.

Nowadays, the key technical achievements of waterborne embossing ecological synthetic leather, water-borne release paper, high solid waterborne polyurethane resin and a series of water-based synthetic leather have been breakthroughs and widely applied in Lishui Development Zone, and have gained the leading position in the world.

< /p >

< p > in just a few years, 8 synthetic water-based synthetic leather production lines of Lishui synthetic leather leather company, such as yhe, Wuzhou, Fangyuan, Li bang and min Feng, have been built and put into production, accumulatively using more than 6300 tons of waterborne resin and reducing over 6000 tons of organic waste gas.

< p > > a href= "http://www.91se91.com/news/index_c.asp" > environmental protection new product < /a > can it have market competitiveness? The cost has risen significantly, and the scale effect has to be brought about by scale development, < /p >

< p > can aquatic eco synthetic leather produce qualified clothing, shoes, bags and sofa products? Can its cost be competitive in the market? Can it replace the oil-based synthetic leather products, really go to the market and usher in the new "spring" of the synthetic leather industry? < /p >

< p > in the exhibition hall of Lishui bamboo charcoal leather synthetic leather Research Institute, it is covered with dazzling leather garments, shoes bags and synthetic leather fabrics.

The reporter felt that the leather material was soft and had no difference from the real leather.

According to experts, aquatic eco synthetic leather has little environmental impact on its production and processing, and its products will eventually be biodegradable and will not cause new pollution.

< /p >

< p > because of the mature technology now, compared with the traditional synthetic leather, the water-based eco synthetic leather has the characteristics of safety, comfort, durability and dirt resistance. The products are non-toxic, environmental friendly, breathable and moisture permeable, and have excellent handle. The water bamboo charcoal products produced can meet the needs of sofa, automobile interior decoration, shoes and bags, garments and other products.
