Abstract
Process particularly suitable for sheet material of the type comprising a porous polyurethane resin matrix, the latter containing polyester or polyethylene fibres, and a pressed polyurethane resin cover film patterned to imitate real leather; the said process consisting in treating the said material, inside rotary tanning drums, with a trivalent metal salt solution which is brought up to precipitation pH level in such a manner as to fill the pores in the said polyurethane matrix on the said sheet material with a corresponding hydroxide, after which, the material is treated with a dialdehyde, fireproofing, colouring and softening substances.
