On December 16, the 2020 provincial key project-SDJC Nonwoven Technology Co., Ltd. held a new composite new material production ceremony. After being put into production, the project will produce China's first high-end new polypropylene filament 6-meter wide product, which will break the long-term foreign monopoly on China's high-end non-woven polypropylene filament geotextile.
The first 6-meter ultra-wide polypropylene filament geotextile production line project successfully put into operation in China broke through the technical bottlenecks of “tear strength” and “tensile strength” that have been constrained in China for many years. The product breaks the international monopoly and leads the world in performance. It can be used in key areas of national economy and people's livelihood such as water conservancy and hydropower, aerospace, and sponge cities. It can also serve the infrastructure construction of countries along the "Belt and Road", which will promote the globalization of China's high-end nonwoven materials application.
China is already a major country in the global geosynthetic product manufacturing and engineering application power. In particular, geotextiles are an important branch of geosynthetics with the fastest technology development and the most complete variety. It is also the category of industrial textiles that is second only to medical and filtration textiles in the field of industrial textiles. It has high-tech content, high added value and high cost performance. It has been widely used in various fields of water conservancy, transportation, ocean, port, environmental protection and other projects, and has become a key basic material for infrastructure and major project construction.
SDJC has the world's advanced polypropylene filament geotextile production line and China's advanced staple fiber needle-punched geotextile production line, high-density polyethylene geomembrane production line, etc.
The polypropylene filament geotextile production line adopts the process equipment production line jointly developed by Oerlikon of Switzerland and Barmag of Germany.
The product has good chemical resistance, prolongs the service life of the product, and is also harmful to engineering safety and the surrounding environment during use. Will not produce pollution. The product can be widely used in highways, railways, airports, ports, tunnels, rail transit, water conservancy and hydropower, sponge cities, national defense construction, garbage landfills, tundra, soil restoration and other major military and civilian engineering construction fields.
