Netted geotextiles

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. 

PP application is hindered by dyeing difficulties, but its cheapness has resulted in very fast growth in the developed world since 1980, especially in carpets, non-wovens, and ropes. Carpet growth is slower in the third world, comparative with disposable nonwovens. However, low cost ropes and nets, and items like geotextiles and agrotextiles are likely to find rapid deployment worldwide. 

A antimicrobial treatment is useful for some applications of PP fibers clothing for work and sport wears, floor coverings, geotextiles, fishing nets, and ropes. 

Geotextiles are widely used in developed nations to overcome numerous geotechnical engineering-related problems efficiently, safely and economically. Geotextile materials may be of a nonwoven, woven, knitted, netted, sandwiched or composite stracture. The use of geotextiles is specific to the location, so in addition to the inherent...

Netted PE shaded geotextile nets can protect cattle and livestock from high-UV exposure during the day. They also create shady areas for relaxation during hot summer days. 

An offshore net cage is a fishing net system with a frame structure and a geotextile net cage. It can be used to raise different kinds of fish within a confined space using fresh and clean seawater. Farmed fish have a quahty similar to that of fish caught in the ocean.
