There is already a high penetration of nonwovens in construction sector and the present paper only refers to the specific case of sound insulation. For each application there is still room for value added products and that will only further consolidated nonwovens position. When they have to choose between varieties of products, manufacturers consider following criteria: economics, durability, aesthetics, processibility, mouldability, added benefits (eg, acoustics, flame retardant, recyclable, etc), which are main driving forces of nonwoven in construction industry worldwide. The use of textiles for noise reduction is based on two major advantages of these materials, namely low production costs and small specific gravity. As the acoustic textile materials currently used in motor vehicles represent low quantities, one cannot expect them to become economically recycled because they consist of 2 to 5 fibre components blends and they are moreover combined wjth non-textile materials (metal, plastic materials) thus not very cost-effective to dissemble. Besides that, due to ageing and contamination, these textiles have, in many cases, no value with regard to recycling. In this respect, EU regulation offers the framework to solve these problems and open up a chance for the textile industry. The main challenge for acoustic automotive textiles manufacturers can be synthesized as following: process recyclable materials today, optimally recycle them tomorrow and optimally dispose them the day after tomorrow.
