ADHESION OF RAYON TEXTILE TO RUBBER WITH AQUEOUS DISPERSION OF BLOCKED ISOCYANATE OR ISOCYANATE DIMER, RUBBER LATEX AND RESORCINOL-FORMALDEHYDE RESIN

摘要

Rayon or nylon textile material (e.g., tire cord) which fails to develop adequate adhesion to rubber when pre-treated with the conventional aqueous RFL solutioning bath, is re-treated with an RFL solution to which an aqueous slurry of blocked isocyanate or isocyanate dimer has been added. The re-treated textile is dried and laminated to vulcanizable rubber stock. Upon vulcanization of the rubber, the re-treated textile develops satisfactory adhesion.
