Abstract
A conveyor belt includes a bottom fabric layer having a lower first surface forming a backside of the conveyor belt and an upper first surface, wherein the lower first surface is impregnated with an impregnation having: a) one or more thermoplastic polyolefins selected from the group consisting of ethene homopolymers, propene homopolymers, ethene/α-olefin copolymers, propene/α-olefin copolymers and terpolymers of ethene with two or more different α-olefins; and b) a thermoplastic polymeric dispersing agent containing repetitive units derived from at least one ethylenically unsaturated monomer of a comparatively lipophilic nature and from at least one ethylenically unsaturated monomer of a comparatively hydrophilic nature and earring an anionic carboxylate group. A process for the manufacture of such belts includes applying the thermoplastic polyolefin(s) and the thermoplastic polymeric dispersing agent as an aqueous dispersion and heating the lower first surface having the dispersion applied thereonto.
