Abstract

Process for the production of a fibrous non-woven sheet composed of fibers or filaments, or mixtures of fibers and filaments, in which the fibers or filaments are entangled with other threads or filaments in such a way that the degree of impenetrability in the highly entangled areas are at least 0.5 when the sheet is unattached and also that the entanglement frequency (f) is at least 7.9 centimeters when it is determined in the unbonded state characterized by consists (a) in subjecting a layer of fibers placed on a support element to a thin columnar jet of a non-compressible fluid that leaves a hole to force the fibers or filaments to move relative to each other under the impact force of the jet, (b) said jet having a quantity of movement flow of at least 6 kg m/s2-cm2 at the point of impact on the web and preferably having a velocity of more than 6,000 cm/s at the outlet of the orifice, (c) in the eventual displacement of the fluid outlet orifice relative to the fiber web, (d) the support element of the sheet during the treatment has perforations distributed, so as to eventually give the fiber sheet a perforated appearance, (e) in eventually treating said sheet subsequently to improve the textile properties thereof.
