Abstract
An absorbent textile sheet material suitable for use as a cleaning cloth, skid-resistant underlayment or the like, comprising a consolidated nonwoven fabric coated on up to about 70% of both surfaces with binding agent present as a three-dimensionally superelevated printed pattern providing a squeegee-like action when wiped over a wet surface, is produced by impregnating a fibrous web with a binding agent and drying to form a coherent sheet material, applying to each surface of said sheet material a foamed dispersion comprising rubber, the foam being printed onto each surface to cover from about 30 to 70% of the surface, and heating to coagulate the foam and to leave on each surface a superelevated printed pattern of binder exerting a squeegee-like action in use. Advantageously the fibrous web weighs about 60 to 300 g/m.sup.2, the foamed dispersion contains butadiene-acrylonitrile-styrene-rubber copolymer, is applied to each surface in amount sufficient to deposit about 20 to 40 g of rubber per square meter of surface in a final height of about 0.3 to 1.5 mm and is printed in a pattern which permits no straight lines longer than about 10 mm to be drawn on a surface without intersecting the superelevated pattern.
