Claims25
A nonwoven dust cloth, said dust cloth comprising at least one elastomeric nonwoven composite web comprising an admixture of:
- elastomeric meltblown fibers formed from a material selected from the group consisting of one or more of poly(ethylene-vinyl acetate), thermoplastic polyurethanes, A-B-A' block copolymers, blends of one or more of poly(ethylene-vinyl acetate), thermoplastic polyurethanes, and A-B-A' block copolymers, and blends of one or more poly(ethylen-vinyl acetate), thermoplastic polyurethanes, and A-B-A' block copolymers with one or more polyolefins, and
- at least one nonelastomeric fibrous material,
- said web having:
- elasticity in at least one direction;
- said cloth being characterized by a dust gathering capacity of at least about 0.185 grams per inch square of web;
- and an abrasion resistance of at least about 50 cycles on a Taber scale.
