高性能、高效益新型聚丙烯土工织物

In this project, the scientific principle for manufacturing high strength polypropylene filament and flat fiber, as well as the preparation technology of their specific resins were investigated. The interactions between different components of the alloyed resins were characterized, and also the influence of additives on the physical properties of the alloyed resin was studied. Several kinds of alloyed resin with excellent spinning properties were developed. Some key problems existing during the spinning experiments have been resolved. Novel geotextile made of high strength PP fiber and flat fiber was obtained. Our high performance geotextile and PP flat fiber geotextile have been successfully used in Inner Mongolia for desert-prevention
