Abstract
The present invention relates to a process for the continuous production of a multi-layer web comprising an exterior covering and a nonwoven material disposed underneath. According to the present invention, a nonwoven material which has been prebonded is used as the starting product, and the steps of additional bonding, calibrating, and smoothing of the nonwoven material and of laminating the nonwoven material and the exterior covering are combined in a single process. The present invention, in addition to achieving a cost advantage, also produces a covering material that provides better sitting conditions, equivalent to the foam backed covering materials with respect to physical textile values yet being easier to recycle and. In addition, recycled textile products can be worked into the covering material of the present invention as reprocessed fibers without losing any advantage.
