Geotextiles developments

However, this review will be somewhat different from the others in that geotextile developments in Europe (initially with nonwoven fabrics) will be presented first, with developments in America (initially with woven fabrics) following. The interchange between Europe and America up until 1977 will then be described along with developments in several other countries. Almost immediately after the first international...

In contrast, PET end-use markets have been developing for at least 10 years. When the PET bottle was introduced in 1978 and was collected in states with deposit laws, the industry for recycling them and reusing them began to develop. PET resins can be reused to make polyols for insulation and unsaturated resins for bathtubs, shower stalls, boat hulls, and auto panels. Reclaimed PET is also used for strapping, paint brushes, geotextiles, fibers for fiberfill and carpets, and other textile applications. 

In order for it to perform the reinforcement function, the geotextile must be allowed to deform to develop its strength. When stabilization of a site occurs, there is consolidation of the soil, and with tbis comes deformation of the geotextile. Due to the deformation of the geotextile, strength is required to ensure that a site failure does not occur, ie, there can be a reinforcement component in the stabilization process. 

Polymeric stabilizer materials are a subset of a much larger recent development in civil engineering. ASTM has defined a geosynthetic as a planer product manufactured from polymeric materials used with soil, rock, or other geotechnical-related material as part of a civil engineering system. A geotextile is a permeable geosynthetic made of textile materials. 

The world consumes in excess of 2.5 million tons of PP in nonwovens today. According to a report by Chemicals Market Resources Inc. Diapers, adult incontinence products, geotextile and carpets, are the end use applications expected to see rapid increase in demand in developing regions [19]. 

The well-known possibilities of the use of textiles and fibres in construction have developed into fields of application ranging from geotextiles to fibre-reinforced concrete, concrete reinforcing armatures made of fibre-reinforced polymers, usually carbon fibre composites (CFCs), textile membranes and sheeting and to constructions made of fibre-reinforced polymers as multi-layer composites. The present book is dedicated to the spectrum of building geotextiles are excluded, since they are less commonly used for building construction and are more common in earthworks, transit structures and landfills.
