Geotextiles are porous synthetic fabrics and are often constructed of polyester or polypropylene. Geotextiles are used extensively in many industrial, coastal, and geotechnical engineering constructions for filtration, drainage, separation, and protection. Non-Woven Geotextile Fabric connects long or short fibers using needle punching or other processes. The geotextile is then subjected to further heat treatment to increase its strength. What are the types of Non-woven geotextile fabrics? In the industry, nonwoven textiles are made without using the standard techniques for weaving or connecting filaments. There are four types of nonwoven fabrics: • Spunbond or Spunlace The Spunbond interaction involves using air flows or redirectors to transform the threads into a web, which are then simply spread across the web. They are high-temperature and do not include any synthetic materials. Spun Bonds are extremely lightweight, strong, highly air permeable, hydrophilic, and have i...
