Abstract: The invention relates to a textile bonding composition comprising a salt of lignosulfonate, an aldehyde hardener thereof, and an elastomer latex. The lignosulfonate salt may be sodium, potassium, magnesium, ammonium, or calcium lignosulfonate. The invention also relates to the use of such a composition for imparting adhesion properties to a reinforcement textile, with regard to a rubber, a reinforcement textile, in particular yarn, cord or textile structure, at least partially coated and/or impregnated with this composition, and a part made of rubber or comprising a rubber, in which the rubber comprises at least one reinforcement textile, on the surface and/or integrated inside the rubber.

Abstract: The invention relates to an adhesion-promoting composition for a textile material, comprising a salt of lignosulphonate, an epoxy hardener for said salt, comprising at least two epoxide units, and an elastomer latex. The lignosulphonate salt can be a lignosulphonate of sodium, potassium, magnesium, ammonium or calcium. The invention also relates to the use of such a composition for providing a reinforcing textile material with adhesive properties, in relation to a rubber material, to a reinforcing textile material, particularly a textile structure, thread or cord, at least partially coated and/or impregnated with said composition, and to a part consisting of rubber or comprising a rubber material, in which the rubber comprises at least one reinforcing textile material, on the surface thereof and/or integrated into the rubber material.
