摘要
总结分析了土工布的生产工艺类型和原料种类,提出非织造型土工布具有更为广泛的应用领域;介绍了长丝纺粘针刺技术和短纤针刺技术两种非织造型土工布生产工艺;基于土工布的功能分析,指出防渗工程、高铁无砟轨道滑动层、粉煤灰堆场工程、尾矿库堆场工程、矿山堆浸场工程和生态袋边坡防护工程等应用领域对土工布提出了高强度、耐酸碱性、耐腐蚀性和耐霉变性等高标准要求,提出了高强、耐环境型聚丙烯长丝纺粘针刺土工布是土工布行业的重要发展方向。
Based on analyzing different production processes and types of raw materials for geotextiles, the paper points out that nonwoven geotextiles have broader application fields. It also introduces two kinds of nonwoven geotextiles production processes, one is based on filament spun-bonding and needle-punching technology, and the other is based on staple needle-punching technology. Then, by analyzing the functions of geotextiles, it further points out that current applications, such as seepage prevention projects, the sliding layer of ballastless track of high-speed railway, fly ash dump yard projects, tailings dump yard projects, mine dump leaching projects and ecological bag for slope protection, have posed higher requirements on the tenacity, alkali/acid resistance, corrosion resistance and mildew resistance, etc. of geotextiles, therefore, high-tenacity and environment-resistant polypropylene filament spun-bonded and needle-punched geotextiles represent a key developing trend of the geotextiles industry.
