Shoe Material Excipient Application Link Rise Green Innovation

Against the backdrop of the International Year of chemistry and the green and low carbon economy, the 2011 system shoes Enterprises, rather than the ability to compete in R & D products, is a test of green production. From shoe making equipment, shoe sole material, shoe upper fabric to glue production and so on, domestic shoemaking enterprises will deepen innovation and reform from various aspects and deal with the "green" test.

Since 11th Five-Year, China's shoemaking industry has been developing rapidly. According to incomplete statistics, there are more than 30 thousand footwear producing enterprises in China, and more than 400 direct practitioners. China's footwear industry is now the world's largest shoe manufacturer with the annual output of over 10 billion pairs of shoes. It is estimated that more than 300 thousand tons of organic volatiles are emitted into the atmosphere every year, causing serious pollution to the environment. At the same time, some enterprises, especially small and medium-sized enterprises, use adhesive containing "three benzene", which can cause chronic occupational poisoning, such as carcinogenesis, leukemia, infertility, respiratory diseases and so on. Coupled with poor ventilation conditions and even no ventilation at all, the occurrence of benzene poisoning in production workers and the incidence of occupational diseases are high.

In recent years, with the implementation and updating of the EU REACH regulations, the footwear industry in China is a labor-intensive industry. The chemicals involved in the products involve a large amount of risk chemicals, a wide variety of products. In addition, the export enterprises of the European Union do not attach enough importance to foreign standards and regulations, and lack of research. This makes exporters more passive in the face of technical measures. Many enterprises still have some mistaken ideas about the REACH regulations. In the first quarter of 2010, according to official statistics from the United States and the European Union, China's export footwear products were recalled by the United States and Europe in 31 batches, representing a sharp increase of 40% compared with the same period of the previous year. Among them, the content of azo, formaldehyde and six valent chromium in raw materials far exceeded international standards. Chemical pollution is the most important reason for the recall of footwear products, accounting for 82.48% of the total recall. Therefore, it is urgent and urgent to seek environmental protection solutions for China's footwear industry.

With the emphasis on environmental protection by high-level government and relevant government departments, nowadays, the "three benzene" adhesive It has been greatly restricted, and some enterprises' products have been ordered to withdraw from the market. At the same time, a series of environmental laws and regulations have been promulgated, creating a healthier atmosphere for the market. According to the reporter, Fujian Province, a big shoemaking Province, controls the pollution of "three benzene". Safeguarding the legitimate rights and interests of employees has long been placed on the agenda of the provincial Party committee and the provincial government. Last year and this year, the renovation of "three benzene" waste gas has been classified as a real project for the provincial Party committee and the provincial government for two consecutive years. Fujian province has promulgated the management measures for the use of benzene free adhesives in the footwear industry of Fujian Province, popularizing the use of benzene free adhesives, and comprehensively regulating the market for benzene free. All the benzene free adhesives entering the province must be identified by the provincial environmental protection department. According to the relevant regulations of the provincial environmental protection industry market management, the production and distribution units without benzene adhesive must also be accreditation by the provincial environmental protection department. The environmental protection departments at all levels will cooperate with law enforcement departments, such as industry and commerce, labor, health and technical supervision, to prohibit the production, sale and use of benzene free adhesives identified by the provincial environmental protection departments, and restrict the use of "three benzene" adhesives for shoemaking enterprises. The use of "three benzene" waste gas purification treatment must be carried out.

For a long time, 95% of the traditional shoemaking enterprises use neoprene adhesive, a large number of organic solvents will be discharged into the atmosphere every year, and there will be a certain degree of benzene pollution. Last year, many small and medium-sized shoe materials enterprises actively explored new markets, only to maintain a small increase in exports. Nowadays, under the background of green ecology, energy saving and emission reduction, the export of shoes products will face more environmental pressure.

Peng Jinxin, vice chairman of the national science and Technology Commission of the Ministry of environmental protection, vice chairman of the China Low Carbon Economic Development Promotion Association and vice chairman of the academic committee of the international low carbon economy research center, pointed out that we must vigorously guide enterprises to promote product innovation based on technological innovation, and actively develop environmentally friendly, high-tech, high value-added footwear products, and adjust footwear export varieties according to the requirements of different markets and different periods. In this way, we can successfully cope with the green barriers and create a healthier and more harmonious living environment for ourselves.

At present, China's environmental protection shoe sole material, Shoe upper Great breakthrough has been made in research and development of fabrics and adhesives, green dyes and auxiliaries. Such as the Fujian Institute of Chinese Academy of Sciences and KELONG Huayu (Fujian) science and Technology Development Co., Ltd., the key project of the national "863" plan has been industrialized. The two phase of capacity expansion can reach more than 30 thousand tons. The project will fill the industry blank of the domestic new type of water-based adhesive. The product has strong adhesion, no toxicity, no smell, no static electricity, friendly to the human body and environment, and can be widely used. It can replace the traditional oil containing shoemaking containing benzene glue. Compared with imported PU shoes (waterborne shoes), it can reduce the cost by 20%.
