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.
