丙纶土工布主要有织造土工布、土工膜、复合土工布。其中织造土工布又分为机织土工布和编织土工布。
Polypropylene geotextiles are mainly woven geotextiles, geomembrane and composite geotextiles. The weaving geotextiles are divided into woven geotextiles and woven geotextiles.
丙纶土工布的特点是:
The characteristics of polypropylene geotextiles are as follows:
1.丙纶机织土工布都是在宽幅有梭织机或片梭、剑杆等无梭织机上生产。
1. Polypropylene woven geotextiles are produced on shuttle looms or shuttleless looms such as shuttle looms and rapier looms.
丙纶机织土工布比较适宜发挥增强加固的功能，所以作为分离、增强、控制浸蚀应用时，一般采用机织土工布。
Polypropylene woven geotextiles are more suitable for strengthening, so woven geotextiles are generally used as separation, reinforcement and erosion control applications.
2.非织造丙纶土工布
2. Nonwoven polypropylene Geotextiles
非织造土工布一般是在连续生产线上制得。聚丙烯非织造土工布按生产工艺主要分为纺粘法、短纤维针刺法两种。
Nonwoven geotextiles are usually made on continuous production lines. Polypropylene nonwoven geotextiles are mainly divided into two kinds according to the production process: spinning-bonding method and short fiber needling method.
而涤纶土工布是非织造及工业用布的一种。是采用纤维纤度为6-12旦，长度为54-64mm的涤纶卷曲短纤维为原材料。通过无纺生产设备的开松，梳理，杂乱（短纤维相互交织在一起），铺网（规格化缠结），针刺等生产工艺的流程制成布状。
Polyester geotextile is a kind of non-woven and industrial fabric. It uses polyester crimped staple fibers with 6-12 denier fibers and 54-64 mm length as raw materials. Through the opening, carding, disorder (staple fibers intertwined), netting (standardized entanglement), needling and other production processes of non-woven production equipment to make cloth.
