REINFORCED TEXTILE SUPPORT WITH CELLULOSIC FIBER MULTI-FILAMENTS FOR BITUMINOUS MEMBRANES

摘要

A reinforced textile support, particularly for bituminous membranes, made of at least one layer of polyester non woven web and continuous high modulus reinforcement yarns longitudinally set with respect to said layer. The reinforcement yarns consist of cellulosic fibre multi-filaments of the Lyocell type. The assembly is bound by mechanical needling or water entangling, stabilised by means of thermal treatment at a temperature of 200-250°C and consolidated by means of a chemical binder.
