To obtain a wiping cloth resistant to compressional-flattening, esp. excellent in wiping-off ability while retaining its unique performances such as flexibility, water-holding ability, water-absorbing ability and resistance to washing, thus suitable as an industrial wiper or dishcloth.
First, a spunbonded nonwoven fabric is produced by melt spinning of a thermoplastic resin into numerous filaments which are then collected into a web which is then imparted with regular and intermittent self-fused areas. Next, one side of the spunbonded nonwoven fabric is laminated with a paper sheet comprising numerous pulp fibers followed by penetrating a high- pressure water column jet from the face side of the paper sheet toward the spunbonded nonwoven fabric side to effect interlaced integration of the pulp fibers and nonwoven fabric filaments into a composite sheet which is then incorporated with a synthetic polymeric resin, thus obtaining the objective wiping cloth. The paper sheet contains 4-75wt.% of the intrafiber-crosslinked pulp fibers.
