According to the statistics of "China's mechanism carpet for 30 years", the total number of national mechanism carpets in 2016 was 281,753,600 square meters, of which Akemin and Wilton carpets were 66,656,400 square meters, and tufted carpets were 1,561,612 square meters. According to this calculation, the whole industry latex That is to use more than 100,000 tons of latex.

The carpet latex is mainly composed of styrene-butadiene latex and vinegar-acrylic latex. No matter which type of latex is used, most of them are polymerized with monomers such as butadiene, styrene, vinyl acetate, butyl acrylate and vinyl acetate. The upstream production process is chemical. Synthetic, not environmentally friendly; during the drying process, the solvent volatilized, the remaining harmful monomers and the polymer are decomposed and decomposed by heat, which causes certain harm to the environment. The carpet manufacturer must invest in the “VOC” treatment facility to achieve the corresponding The environmental protection requirements; the drying process will cause the carpet to produce wet heat shrinkage, reduce the product production rate; in the entire production process, the glue coating and drying and curing process, low efficiency, high energy consumption, high temperature in the production environment, is not conducive to the health of workers.

In addition, in order to achieve the standard of the pull-out force and reduce the coefficient of variation, it is often adopted to increase the amount of glue applied, which is easy to cause the phenomenon of penetration and seriously reduce the quality of the carpet. As a mechanism for medium and high-grade carpets, Akemin carpets and Wilton carpets often lose their elasticity due to excessive rubber coating, making their quality difficult to match with handmade carpets. High-glued tufted carpets can only be used as low-grade carpets. Impairing the product image of the industry limits the potential of carpet manufacturers to improve their economic efficiency.

In recent years, in order to overcome the defects of the carpet latex adhesive process, hot melt adhesives, hot melt powders, hot melt films, jet technology and other processes have been developed at home and abroad, but due to factors such as limited applicability, high energy consumption, and unguaranteed quality, Unable to spread.

In the actual use scenario, most of the mechanism carpets contain calcium carbonate powder, which is difficult to recycle after being discarded. As the market usage increases year by year, how to deal with carpet garbage becomes a difficult problem. With the improvement of economic consumption level, consumers are increasingly demanding indoor environment for work and life. It is added to the national environment of “energy saving, low carbon cycle, green production”, high energy consumption and exhaust emissions in the manufacturing process. Many factors, such as the environmental protection “Ya Li Shan Da”, have forced the entire carpet industry to abandon the old production process, and innovation and change are imminent.

Reverse thinking, innovative latex-free production

The existing carpet latex application innovation has entered a bottleneck period. No matter how the change is carried out, under the current technology and material conditions, green environmental protection production and application cannot be fully realized. Innovation often requires reverse thinking. “The refrigeration industry has abandoned Freon. Can we abandon latex?” The technical team of Oriental Carpet Group Co., Ltd. boldly proposed this idea. Abandoning latex completely, responding to the national low-carbon green environmental protection industry policy, catering to the needs of consumers to enhance the working and living environment, ending the production and application of latex from the source, and revolutionizing the transformation of carpet production mode has become the direction of innovation.

Recently, the Oriental carpet “Key Technology Research and Industrialization of Latex-Free Environmentally Friendly Carpet” project passed the acceptance of the Expert Group of China Textile Industry Federation. The expert group unanimously determined that the innovation has improved the product texture and performance and solved the carpet adhesive. The bottleneck problem of low production efficiency, high energy consumption and great environmental impact is a major innovation in the process technology of the mechanism carpet; the project has achieved large-scale production, and the products have been tested to meet the national standards (GB18587-2001-A), products The added value is high, the social and economic benefits are significant, and the market prospect is broad; the project has independent intellectual property rights, and the overall technology has reached the international leading level.
