- Title
Technical nonwovens for protective applications – new approaches in the field of needling technology.
- Abstract
The concept of stabilizing and hardening earthwork with natural materials can be traced back to 3,000 B.C. According to records, woven fabric and reeds were found in Babylon. Thousands of years later, the basic principle has not changed. However the methods and materials can hardly be compared at all with the techniques used back then. While materials like wood, stone, concrete and even cotton were still used into the 20th century in the area of road construction, the focus is now mainly on synthetic polymers generally known as plastics. Nonwovens (including thermally bonded spunbond mats) started being used in the middle of the 1960s. At the end of the 1960s, the first needled nonwovens were used in earthworks by Rhône-Poulenc Textile, France. It took another 20 years for standardization and standards for geosynthetics (ASTM, ISO, BSI) to become a serious focal point. Gustav Wizemann Groz-Beckert KG, Albstadt/Germany
