Abstract: The present application discloses a method for making a rubber blade. The method includes applying a first coating composition and a second coating composition in separate steps on at least a part of a surface of a polyurethane elastic substrate; and solidifying the first coating composition and the second coating composition by ultraviolet light irradiating to form a hardened layer on the surface of the polyurethane elastic substrate. The first coating composition includes an isocyanate-group-terminated polyisocyanate and a first solvent. The second coating composition includes a first monomer, a photoinitiator, and a second solvent. The first monomer is at least one of an acrylate monomer and a methacrylate monomer each having an reactive hydroxyl group. The isocyanate group of the polyisocyanate is reacted with the reactive hydroxyl group of the first monomer to generate a urethane group to form a polyurethane acrylate. The present application also discloses a rubber blade.

Abstract: A sliding sheet includes a fabric layer is disclosed. The fabric layer includes warp yarns and weft yarns. The warp yarns are interlaced with the weft yarns. The sliding sheet has a first edge extending in a length direction of the sliding sheet. The warp yarns are bent toward a middle portion of the first edge. A method for manufacturing the sliding sheet is also disclosed. An auxiliary yarn is woven with the warp yarns and the weft yarns to form a fabric raw layer. A tension for weaving the auxiliary yarn is adjusted so that the tension of the auxiliary yarn is greater than the tension of the warp yarns, thereby bending the warp yarns in the fabric raw layer toward the auxiliary yarn. The fabric raw layer is heated to fix the shape of yarns, and cut into the fabric layer to form the sliding sheet.
