ABSORBENT NONWOVEN FABRIC CONTAINING STAPLE LENGTH POLYESTER/POLYETHYLENE CONJUGATE FIBERS AND ABSORBENT FIBERS Abstract There is disclosed a low density, highly absorbent, thermal bonded, nonwoven fabric comprising absorbent fibers and staple length polyester/polyethylene conjugate fibers that is produced by the steps of: (a) producing a mixture of such fibers to produce a fibrous web; (b) subjecting said web to a temperature sufficient to fuse the polyethylene component of said conjugate fibers without fusing the polyester component of said conjugate fibers, while maintaining the web under little or no compression; and (c) cooling said web to re-solidify the polyethylene component of said conjugate fibers, to thereby form bonds at the sites where said conjugate fibers touch other fibers.
