Abstract

The present invention relates to a method for producing a velour rug, comprising the following steps: a) needling of a nonwoven/mali nonwoven on a bristle strip using a needling machine, in the process of which a pile nonwoven/carrier nonwoven is pulled into and partially back out of the bristle strip such that the fibers of the pile nonwoven/carrier nonwoven are located in the plane of the bristle strip, b) separating the nonwoven from the bristle strip by means of a roller brush, c) brushing the pile side prior to cutting the loops, characterized in that, in order to increase the fiber density and enhance the pile stability, an additional nonwoven/mali nonwoven, especially a pile nonwoven/carrier nonwoven, is placed onto the reverse of the nonwoven/mali nonwoven, especially between a first and second needling unit, between steps a) and b).

Claims

1 - 8 . (canceled) 
     
     
         12 . A process for preparing a velour carpet, comprising the following steps:
 a) needling a web/Malifleece on a brush belt using a needling machine, a pile/support web being drawn into the brush belt and partially back again, so that the fibers of the pile/support web are in the plane of the brush belt;   b) separating the web from the brush belt by means of a roller brush;   c) brushing up the pile side before the loops are cut open;   characterized in that a further web/Malifleece, including a pile/support web, is applied to the back side of the web/Malifleece between steps a) and b), to increase the fiber density and enhance the pile stability.   
     
     
         13 . The process according to  claim 12 , characterized in that steps b) and c) are performed simultaneously. 
     
     
         14 . The process according to  claim 12 , characterized in that the back side of the web/Malifleece is sprayed with water and dried and integrated after step c). 
     
     
         15 . The process according to  claims 12 , characterized in that the pile side of the web is brushed against the grain after step c) for erecting the fibers, and protruding fibers are shorn off. 
     
     
         16 . The process according to  claim 12 , characterized in that a web/Malifleece including a pile/support web comprising fibers of PP, PES, PA or mixtures thereof is employed. 
     
     
         17 . The process according to  claim 12 , characterized in that a web/Malifleece including a pile yarn whose fibers have a yarn count within a range of from 3.3 to 11 dtex is employed. 
     
     
         18 . The process according to  claim 12 , characterized in that a densified pile/support web, including a web/Malifleece with a longitudinal/transversal strength ratio of 1.0/1.2-1.4, is employed as the web/Malifleece. 
     
     
         19 . The process according to  claim 12 , characterized in that a further web/Malifleece, including a pile/support web, is applied to the side of the web/Malifleece facing away from the brush belt between steps a) and b). 
     
     
         20 . The process according to  claim 12 , characterized in that applying the web/Malifleece occurs between a 1 st  and 2 nd  needling unit. 
     
     
         21 . The process according to  claim 19 , characterized in that applying the web/Malifleece occurs between a 1 st  and 2 nd  needling unit. 
     
     
         22 . The process according to  claim 14 , wherein when the web/Malifleece is dried, it is dried without tension.
