Abstract
The present invention overcomes drawbacks of prior composite sheets consisting of a spun-bonded nonwoven fabric and pulp fibers and provides an inexpensive composite sheet with excellent draping qualities, a nearly fabric-like touch and good usability. According to the present invention, a composite sheet made by entangling a web of thermoplastic filaments with pulp fibers under water stream is creped to increase the elongation in machine direction as high as in cross direction enough to obtain a usability equal to those of fabric wipers.
