ABSTRACT:
A polyethylene terephthalate material (e.g., a filament or cord) is disclosed that exhibits desirable adhesive characteristics in rubber-reinforcing applications. An important aspect of the invention is the incorporation of a radiation-curable acrylate monomer in a spin finish coating or as a coating applied upon a spin finish coating, and the subsequent photopolymerization of the acrylate monomer by exposure of the coated filament or cord to a suitable radiation source. The surface-modified material thus shows an improved adhesion to phenolicformaldehyde-latex adhesives.
