ABSTRACT:
An improved process is described for obtaining synthetic hides similar to natural hides by application, to a composite sheet material formed of a porous polymeric matrix within which are embedded fibres, preferably polyamides, of a tanning phase entirely similar to that utilized on natural hides, followed by a treatment with an aqueous solution of a di- or polyaldehide and by a stuffing phase, also entirely similar to that utilized on natural hides; the improved principle consists in effecting, between the tanning phase and the treatment with the di- or polyaldehide, a filling phase in which synthetic polymeric resins mixed with synthetic and/or natural tannins are introduced and fixed into the porous matrix.
