Geotextiles polymers

System type 4 Recycled mat type R(2) with geotextile polymer sheet thickness h=8 mm PVC material type M<3) thickness d=3 mm Polymeric geotextile sheet with weight of 300 g/m2... 

Samples to be tested were kept more than 61 hours in the temperature condition of 23°C and relative humidity of 50% this corresponded to the requirements of SN-ISO 291. Sample stripes were taken from the system composed of protective mat, waterproofing membrane, and the underlying polymeric geotextile polymer bedding the length of the strips amounted to 250 mm. The strips were bonded at discrete end points according to the actual conditions of waterproofing systems.

There are several different processes and polymers used ia the manufacture of geotextiles which affect their appearance and physical properties. Geotextiles are produced ia various weights and thicknesses, which also determine their physical properties and ultimately the performance of the material when iastaHed on a project (see also high performance fibers). 

The long lifetimes of geotextiles are shared with a parallel application of plastics underground as impermeable linings to seal canals, reservoirs, tunnels, and, most critical of all, the storage of liquid waste. Generally made from HDPE or PVC, these polymer... 

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. 

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... 

Primary uses for PET from glycolytic recycle are geotextiles, fibers for filling products, nonwovens, and molding resins where color, strength, and control of dyeability is not important. Recovered polymer can be added to virgin polymer for films, fibers, and molding resins.
