In the past, the automotive industry aimed to cover the entire area in the passenger and trunk compartments with fabrics. As the introduction of the EEC end-of-life-vehicles directive 2000/53/EC, requests a rate of 80 % for re-use and recycling in used cars from 2006 onwards we face an increased demand for solutions for this problem. The preferred method in all these developments is a single raw material solution. Al this moment in the car boot the main type of carpets is a needle felt in various constructions. As it is moulded in all the cases there is a latex binder involved. In those cases where people used a high percentage of polypropylene in the floor, there has been some problems which had not been solved yet. On the one hand the high degree of moulding was a serious problem. On the other hand it was difficult to get the necessary dimensional stability in the heat aging test. These points became in fact more important since the moulding sometimes got to an extreme degree in the car boot. By means of a modified production technology and the use of special binder Fibre systems - based on polyolefines - a technical solution was found for this in the form of a Dilour-double layer-construction. The key was the replacement of the latex by the PO binder fibres, taking into consideration all the technical requests such as thermal - and dimensional stability of the final product (car interior). Based on the development work in the needle felt (Dilour- Double Layer Construction) sector the same work was done for the tufted carpets. A tufted carpet made of 100 % polyolefin fibres was developed. Both the primary and the secondary-backing had to be made of a combination of regular and binder fibres. The pile material is a spun yarn, made of 100 % polypropylene fibres (Asota M30). The layer which is mainly responsible for the dimensional - and thermal stability has been taken from the needle felt project. The connection of the tufted carpet with the 'carrier layer' is made - contrary to needle felts - with an extruded film of hotmelt polyolefines. With the help of this modified production technology and the targeted use of PO binder fibres, a technical solution was found in the shape of a 2-layer Dilour/Random velour. The solution meets the future demands of the European automotive industry with regard to recycling.
