Abstract
Abstract A rubberized reinforcing fabric for articles made from elastomeric material includes a plurality of textile cords having at least tensile strength, parallel and adjacent to each other in a same direction, and incorporated in an elastomeric material The cords have a count between 420/2 dTex and 840/2 dTex, a diameter between 0.33 mm and 0.47 mm, and are embedded in the fabric. The fabric has a thickness of not more than 0.8 mm and a density between 125 cords/dm and 280 cords/dm. The cords constitute a maximum of 40% of a volume of the fabric. An article made from elastomeric material, including at least one rubberized reinforcing fabric made from elastomeric material, is also disclosed.
