Abstract

Procedure for the continuous shrinkage of sheets of nonwoven fabric obtained by the wet route, consisting of paper and textile fibers in intimate mixture of which at least one of the constituent fibers has a potential of helical contraction or latent curling, revealed by a chemical or mechanical thermal action, the sheets possibly containing a chemical binder of the constituent fibers, characterized in that a sinusoidal mechanical overfeeding of the sheet is carried out from the moment of the exit of the draining cloth before making it undergo the shrink treatment and after drying.
