Geotextile production process
1, add polypropylene particles; 2, extrusion continuous fiber filament. Re-stretching and contraction, the fibers cut into short fiber; 3, the fiber is placed in the machine leveling; 4, continue to polymer film. The film is cut into filaments; 5, after stretching again, the filament is wound on the reel. 6, through a variety of independent research and development of the production process, the fiber for acupuncture, followed by thermal bonding. 6, through a variety of independent research and development of the production process, the fiber for acupuncture, followed by thermal bonding. Use this production process to create a geotextile with ultimate strength
General spunbond, acupuncture, weaving, weaving, spunlace and other processes,
Geotextile is a big class, there are many forms. Non-woven and non-woven. Non-woven and sub-filament and short wire; sub-mechanical entanglement, hot forming and chemical bonding. Spinning is also divided. Look at the relevant information.
