ABSTRACT:
A laminated fabric material suitable for use in wiping human skin has two plies of fibrous material bonded together. Each ply of fibrous material is a nonwoven web of fibers having a fiber composition consisting of at least 50 wt. % thermally fusible plastic fibers to ensure efficient lamination. In particular, one of the plies consists of 100 wt. % thermally fusible plastic fibers. This enables the plies to be ultrasonically bonded together at sufficiently high bonding speeds. In addition, for the side or sides where an image, for example, a logo, is to be bonded into the fabric, the high percentage of thermoplastic fibers is reduced to ensure that the visibility of the image is not diminished due to swelling of the cellulosic fibers during saturation in aqueous solution. The surfaces of at least some of the thermally fusible plastic fibers of both plies are treated to render the plastic fibers hydrophilic, for example, by coating with surfactant. One ply may have fibers which are relatively coarse, while the other ply has fibers which are relatively fine.
