摘要： A surface covering comprising: one or more layers of the same or different resinous polymeric compositions; and a dimensionally stable fibrous backing material in adhering contact therewith comprising: from about 30% by weight to about 77% by weight of selected proportions of overlapping, intersecting and intermatted polypropylene fibers, glass fibers and wood pulp fibers; from about 0.2% to about 2% by weight of a stable, water-soluble, cationic, quaternary modified acrylamide polymer having a high charge density of from about 350 to about 600 or more milliequivalents/milligram of unit weight and a very high molecular weight of from about 3 million to about 8 million or more; from about 15% to about 60% by weight of a filler or loading agent; and from about 7% to about 27% by weight of a synthetic resinous polymeric binder, all percentages being based on the total weight of the dimensionally stable fibrous backing material. The disclosure also relates to methods of making such surface coverings comprising such a layer or layers of resinous polymeric compositions and such dimensionally stable fibrous backing materials.
