ABSTRACT:
A nonwoven fabric is provided which comprises a layer of nonbonded, polyethylene, plexifilamentary film-fibril strands, which layer is multi-needle stitched with a stitching thread that forms spaced-apart, parallel rows of stitches in the fabric. Stitching thread of spandex yarn which causes the fabric to contract to 35 to 70% of its original area is preferred. The nonwoven fabric is particularly suited for use as a wipe-cloth.
