Description

The invention relates to an impregnation. The pre-needled fleece is now treated with a highly consolidated Fibrebonded floor covering with a binding percentage of latex foam from the loop side medium-free surface. impregnated. The foam impregnation is from the

A disadvantage of this method is ₅ JE a foam is then, as shown in Fig. 2 can be seen to penetrate but that approximately on a needling of the nonwoven fabric at the center of the pre-needled batt. Supporting layer, the latter partially damaged considerably. The binder used is preferably a self-networking, so that the desired effect, namely a zendes styrene-butadiene latex. In this case, it is sufficient to at least partially support the carpet material if the fleece is reversed after the foam impregnation. In addition, 3 ° can be dried briefly at 120 ° C. If the fibers that are not needled into the jute are easily re-crosslinked, they can be removed by pulling. the fleece must be exposed to higher temperatures during

Claims: thin pile. In the case of the needles, some of the parallel fibers are now placed perpendicular to their original direction. Fixed loops are formed on the surface of the fleece, while loops protrude from the lower surface. It is important for usability that the needled fiber loops are distributed as evenly as possible over the surface. Places with fewer fiber loops would face each other 1.
