Abstract
Process for manufacturing artificial leathers by coating fabrics, characterized in that a layer of polyvinyl chloride or polyurethane is placed on a textile support, to which substances a charge of crystallizable salt with several water molecules is added, to effects of achieving the porosity of said layer, whose salts are of crystallographic structure variable with temperature and in which the vaporization of water causes a mass porosity in the plastic coating, which detachment takes place at lower temperatures than gelation and hardening the plastisol, so that open outlet channels are formed that provide breathability to the resulting product, it being feasible to apply a plurality of thin layers, to increase the thickness of the coating, in the event of the channels and to achieve more coincidences between them in the various layers, in order to ensure the breathability of the to (Machine-translation by Google Translate, not legally binding)
