Abstract
A process for manufacturing a bonded fabric for high performance industrial belts is provided. The process includes providing a base fabric made up of warp yarns provided with a predetermined elasticity and weft yarns provided with a lower elasticity than the warp yarns, and subjecting the base fabric to a bonding treatment.
Claims5
A process for manufacturing a bonded fabric for a belt, the process comprising:
- providing a base fabric made up of warp yarns in a longitudinal direction and weft yarns in a transverse direction, orthogonal to the longitudinal direction, wherein the warp yarns are provided with a predefined elasticity and the weft yarns are provided with a lower elasticity than the warp yarns;
- subjecting the base fabric to a bonding treatment, wherein the warp yarns and the weft yarns are coated with a covering made of solidified polymeric materials, wherein the bonding treatment comprises an imbibition step, a drying step in a furnace, and a resinification step,
- wherein, during the imbibition step, the base fabric is impregnated with an aqueous solution based on resorcinol, formaldehyde, and latex;
- and
- wherein, after the resinification step, the bonded fabric has a weight (g/m2) between 20% and 32% greater than the weight of the base fabric.
