Abstract:
    A process for the production of leather intended for making uppers of footwears to be worn in the spring-summer period, in which process, after the traditional bath working step and during the dry working, after the operation of puncturing or piercing the hides, two separate treatments are carried out with acrylic resins which, once polymerized, give the hides respectively on one hand a better compactness and strength and, on the other hand, as a result of coating the skin inner surface at the points corresponding to the punctured or holes, an increase in the surface strength of the skin so that the risks of dilation or stretching and tearing phenomena during wear are avoided. Leather obtained by such a process is intended specifically for making uppers of footwears to be worn during the spring-summer period.
