ABSTRACT:
A hydroentangled composite fabric is made by subjecting a spunbonded base web material of continuous man-made filaments to stretching in the cross direction at least 5 percent of its original dimension but less than the cross direction elongation of the material under ambient temperature conditions at the time of stretching. The base web material in its cross-stretched condition is stabilized to provide a prestretched base web material substantially free from cross direction tensioning. A covering layer of fluid dispersible fibers, preferably in the form of one or more wet-laid wood pulp fibrous webs, is applied to one surface of the relaxed prestretched base web to form a multilayer structure and the multilayer structure is subjected to hydroentanglement while in its relaxed condition to embed the covering fibers in the spunbonded base layer and affix the fiber layer to one surface of the prestretched base material. The resultant fabric exhibits improved dimensional stability and cross-directional strength characteristics closely approaching those in the machine direction.
