Synthetic leather industry: do not promote environmental technology to be eliminated sooner or later

Innovative figures: synthetic leather business executives

Innovation Location: Lishui Economic Development Zone

Innovation speech: When the water-based PU resin applied to any enterprise in Lishui Economic Development Zone, you do not innovate their own technology, it will certainly be eliminated.

Synthetic leather experts effort to join

China is a large producer of synthetic leather, and its output accounts for over 70% of the global total. Wenzhou synthetic leather industry is developing rapidly, now has more than 90 synthetic leather enterprises, with an annual output of 280,000 tons of synthetic leather, accounting for about 50% of the country's total output. In 2002, Wenzhou became the "Capital of Synthetic Leather in China." Since 2005, Lishui Synthetic Leather Industry, which has the same drinking water with Wenzhou City, has also made rapid development. The city has introduced 27 Wenzhou synthetic leather enterprises and 110 production lines. Synthetic leather has become a major pillar industry in Lishui City.

For a long time, chemical products containing a large amount of organic solvents are used in the production of synthetic leather, and 70% of them are toxic and harmful solvents, which not only cause a lot of waste of organic solvents but also pollute the environment seriously, causing great harm to the production workers and causing safety Production accident.

Synthetic leather expert Dr. Fan Haojun told reporters: "If the use of water-based PU resin made of synthetic leather, not only has a high degree of imitation leather, non-toxic full environmental protection and high physical and chemical properties, but also in the production and processing can be done without toxic and harmful gases Emissions, the full realization of cleaner production and safe production, saving a lot of organic solvents, saving a lot of valuable resources for the country. "

"I used to be a leather research, leather and synthetic leather, like a pungent smell in the production process unbearable .I stay in the laboratory, most of the time you have to get out." Fan Haojun emotion Said, "How can employees and technicians survive in this environment?"

Pungent smell comes from traditional organic solvents. In addition to its direct discharge of serious environmental pollution, but also extremely easy to cause a fire. Dr. Fan Haojun said: "There must be a safety and environmental protection alternative technology Caixing. The technology is water-based PU resin."

It is this belief that supported Dr. Fan Haojun spent more than three years from the real leather industry "quit" to the synthetic leather industry, research and promotion of water-based PU resin. Precisely because of this belief, he will advance three years of scientific research time, on behalf of Sichuan University research team, in August 2007 and Lishui Economic Development Zone, Lishui City Qi Leather Co., Ltd. formally signed a cooperation agreement, Vows to help businesses more successfully apply the technology.

However, after the successful development, the application of this technology is not easy.

From worrying to successful cooperation

Water-based resin in the application of synthetic leather there are many difficulties. On the one hand, the difficulties come from the inherent problems of waterborne resins, such as water instead of organic solvents. Due to the large surface tension of water, the surface energy is high, the compatibility of polymers, auxiliaries, inorganic fillers, pigments and other wetting ability is poor; there is also a problem to be improved in the development and production process. Water-based resin such as wear-resistant, scratch-resistant, anti-aging, anti-ultraviolet and so on, we must break one by one, can be used in synthetic leather.

In short, from the application of waterborne resin technology issues have to be resolved, the only way to truly mature product.

A story circulating among Wenzhou-based synthetic leather entrepreneurs: In 2003, a batch of more than 3 tons of "water-based resin" from Jiangsu to a synthetic leather company in Wenzhou was applied in the synthetic leather industry, problem. That enterprise is technically not fully mature "water-based resin," processing of synthetic leather garments, and exported abroad. That batch of clothing to a foreign country, all glued together. Who "the first to eat crabs," Wenzhou boss lose everything. For a time, many Wenzhou synthetic leather business "talk about water color change", then very few people talk about the topic of technological innovation.

"Let enterprises believe our technology, this road, not easy to go." Dr. Fan Haojun Lishui city government so far, resolutely introduce the technology still fresh. August 2007, at the invitation of Lishui Economic and Technological Development Zone, Dr. Fan Haojun of Sichuan University made a demonstration report on "Technical feasibility of environment-friendly PU leather finishing". At that time, the chief executives of the synthetic leather enterprises in the TEDA neither agreed nor obviously opposed it.

However, with the concerted efforts of government agencies including the municipal science and technology bureau and the economic development zone management committee, people of insight still give their full support to this technology. Lishui Qi Li Leather Co., Ltd. and Zhejiang Wuzhou Industrial Co., Ltd. is one of them.

Green products usually mean longer research and development time and a high degree of corporate social responsibility. As a green technology used in the synthetic leather industry, water-borne resins inevitably encounter practical problems in the application process. Faced with these challenges, Zhang Cai, chairman of Zhejiang Wuzhou Industrial Co., told reporters: "With the water-based resin, environmental problems can be solved, we are worth a try."

"No longer have to endure the bad exhaust."

"Synthetic leather produced from water-borne PU resins not only has improved general physical properties and is non-toxic, environmentally friendly, breathable and breathable, and has a superior feel when compared to the synthetic solvent-based processed synthetic leather." Zhang Cai, chairman of Zhejiang Wuzhou Industrial Group, said excitedly: "Synthetic leather made of water-based materials is expected to gain the qualification of 'Ecological Synthetic Leather' from the EU and lay the foundation for the successful development of 'Wuzhou' in foreign markets and toward internationalization. Long-term goal, the use of water-based resin is a matter sooner or later. "

Coincidentally, Qi Li Leather Co., Ltd. Wang Minghai office director also believes that no company is not market-oriented. When the water-based PU resin applied to any one of the enterprises in Lishui Economic Development Zone, you think about the reform of their own technology is lagging behind.

The grass-roots employees of the enterprise are the beneficiaries of the water-based PU resin reform. As Lishui Economic Development Zone, the first company to apply the technology, Qi Li Leather Co., Ltd. employees full of strong sense of happiness. Qi Ming leather office director Wang Minghai reported two data to reporters in the zone of synthetic leather enterprises, Qi Li Leather is a handful of the 2008 Spring Festival employees back to factory rate of 100% of the enterprises. Not only that, an employee with his own 10 villagers to the factory registration. This not only reflects the loyalty of employees, but also the recognition of the improvement of the business environment after the promotion of waterborne PU resin technology.

Zhang Rui, an Guizhou guy who is also working in a synthetic leather business in Lishui Economic Development Zone, said with hope: "Soon afterwards, our business can also apply the technology and everyone will not have to endure the bad exhaust."
