Abstract
A textured fabric having at least one surface that contains peaks and valleys is provided. Greater than about 90% of the peaks and less than about 10% of the valleys are disposed with a treatment composition, the treatment composition comprising a latex polymer. In one embodiment, for example, the textured fabric is a hydraulically entangled composite fabric formed from a spunbond nonwoven web and pulp fibers. When coated onto the fabric, the treatment composition may form a thin film layer on the fiber surface that prevents fibers or zones of fibers from breaking away from the surface as lint. Further, because the coating is applied only to the peaks, the valleys may remain free of the latex polymer and substantially maintain the absorbency of the uncoated fabric.
