Types of Geotextile – Woven Fabrics and NonWoven Fabrics

1. Types of Geotextile – Woven Fabrics and NonWoven Fabrics Geotextile or geosynthetic fabric, is a special type of fabric material used for a wide range of industrial purposes, including the construction of roads, levees, bridges, landfills, retaining walls, harbor works, breakwaters, and drains. ​Geotextile fabric suppliers​ also provide geotextiles for land reclamation, as well as various civil engineering and agricultural purposes. They are permeable fabrics that may be woven, or non-woven in design. Used with soil, these materials work to filter, separate, protect, reinforce, or drain water. Geotextile fabric suppliers produce geosynthetic fabric from materials like polyester or polypropylene. Apart from their use in soil reinforcement, geotextiles have many uses in environmental engineering and geotechnical design. There are many different types of geosynthetic fabrics available on the market today. These specialized fabrics are classified by their configuration, use, basic design, and make. You will find ​woven geotextile​ and nonwoven geotextile fabrics, which are all designed for various engineering purposes. ● Woven geotextile​ – Most geosynthetic fabrics on the market are the woven type, which include several other categories based on the method of manufacturing. Woven geotextiles are produced using techniques similar to clothing textiles, which typically consist of alternating warp and weft extrusions that run perpendicular to one another. Woven geosynthetics are commonly made out of propylene, and come in various forms like monofilament, fibrillated, combination multi-filament, or silt film. A combination of different yarn types is also often used to increase strength and optimize cost and performance. Monofilament and multifilament woven geotextile fabrics offer higher permeability compared to those with slit tape construction. ● Nonwoven geotextile ​– Nonwoven geotextile fabrics are produced from a continuous filament yarn or short staple fiber. Instead of weaving material together, the fibers are bonded using chemical, thermal, or mechanical interlocking. They range in thickness and opening sizes, and the type of fiber used has little effect on the properties of the final product. Mechanically bonded geotextiles tend to be thicker and comparatively heavier, due to the larger quantity of filament they require in order to ensure adequate bonding.
