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.
L'invention concerne un tissu texturé présentant au moins une surface contenant des sommets et des creux. Plus d'environ 90 % des sommets et moins d'environ 10 % des creux sont disposés à l'aide d'une composition de traitement, la composition de traitement comprenant un polymère au latex. Dans un mode de réalisation, par exemple, le tissu texturé est un tissu composite enchevêtré par voie hydraulique formé à partir d'une bande de non-tissé filé-lié et de fibres de pâte. Lorsqu'elle est appliquée au tissu, la composition de traitement peut former une couche en film mince sur la surface des fibres empêchant que des fibres ou des zones de fibres ne se détachent de la surface sous la forme de peluches. De plus, du fait que le revêtement est appliqué uniquement sur les sommets, les creux peuvent rester exempts de polymère au latex et ils peuvent maintenir sensiblement le pouvoir absorbant du tissu non revêtu.
