Synthetic geotextiles

The synthetic materials that best meet in-plane flow rate regulations are called geonets. Geonets require less space than perforated pipe or granular material, promote rapid transmission of liquids, and, because of their relatively open apertures, are less likely to clog. They do, however, require geotextile filters above them and can experience problems with creep and intrusion. 

Synthetic spun fabrics these materials may also be sold as "landscape fabrics" or occasionally "geotextiles," for long-term weed control. They allow water to permeate through them into the soil, but can degrade where exposed to the sun, so cover with a loose mulch to protect them from the light. 

Geotextiles are available as mats, textiles, webs, nets, grids, and sheets. When retention of the contained material is desired synthetic polymers such as polypropylenes, polyesters, nylons, PEs, and PVCs are used because they resist rapid degradation. When only shortterm retention is needed natural materials such as cotton are used. Geotextiles are not always made from fibers, but include film materials such as PE and polypropylene sheets used to retain moisture but retard weed growth in gardens.

One can classify fibers in a variety of ways. For example, one may divide the whole field of fibers into apparel and nonapparel fibers, i.e. based upon the final use of fibrous material. The apparel fibers include synthetic fibers such as nylon, polyester, spandex, and natural fibers such as cotton, jute, sisal, ramie, silk, etc. Nonapparel fibers include aramid, polyethylene, steel, copper, carbon, glass, silicon carbide, and alumina. These nonapparel fibers are used for making cords and ropes, geotextiles, and structural applications such as fiber reinforcements... 

Geotextiles have become one of the most important fields of application for synthetic polymeric fibers. In view of their great importance, we describe them in a separate section. Textiles made of synthetic polymer fibers are used in various applications to address a variety of solids-related problems in civil engineering such as soil support, stabilization, separation and filtration, reinforcement of... 

Both natural and synthetic fibres are used in the manufacture of geotextiles. Natural fibres can be classified based upon their origin, whether plant or vegetable, animal, or mineral. Plant fibres have the greatest potential for use in geotextiles because of their... 

Chemical bonding. A binder such as glue, rubber, casein, latex, cellulose derivative, or a synthetic resin is used for bonding the filaments or short fibres together and these materials are known as chemically or adhesive bonded nonwoven geotextiles.
