ABSTRACT:
A process for the improvement of the adhesion to rubber or a thermoplastic elastomer of synthetic yarns, cords or fabrics made therefrom by applying thereto an adhesive consisting of an aqueous solution or dispersion of a polyurethane with ionic groups, capped isocyanate groups and groups with a Zerewitinoff-active H atom, followed by drying the product thus treated. The polyurethane corresponds to the structure: ##STR1## wherein X has the meaning of an O or S atom or of an O-, S-, N- or P-containing group with a Zerewitinoff-active H atom or to which prior to reaction with an isocyanate group a Zerewitinoff-active H atom had been attached,
