Abstract
The present invention is directed to abrasive webs, composite materials, and methods of making abrasive webs and composite materials.
Claims28
A composite material comprising:
- (a) an outer abrasive layer comprising a first meltblown nonwoven fabric;
- and
- (b) at least one additional fabric bonded to the outer abrasive layer, wherein the composite material contains a plurality of microstretched portions extending along a machine direction of the composite material resulting from microstretching the (a) the outer abrasive layer, (b) the at least one additional nonwoven fabric, or both (a) and (b) in a cross direction.
A wipe material comprising:
- (a) an outer abrasive layer comprising a first meltblown nonwoven fabric;
- (b) a second nonwoven fabric bonded to the outer abrasive layer;
- and
- (c) one or more additives in the outer abrasive layer (a), the second nonwoven fabric (b), or both (a) and (b), wherein the one or more additives comprise a colorant, a scent-producing agent, a surfactant, an antimicrobial agent, or a combination thereof;
- and
- wherein the wipe material contains a plurality of microstretched portions extending along a machine direction of the wipe material resulting from microstretching (a), (b), or both (a) and (b) in a cross direction.

A composite material comprising:
- (a) an outer abrasive layer comprising a first meltblown nonwoven fabric having a basis weight of from about 28 gsm to about 35 gsm, and comprising polypropylene fibers having an average fiber diameter of from about 20 microns (μm) to about 40 μm;
- and
- (b) a second fabric bonded to the outer abrasive layer, wherein the second fabric has a basis weight of from about 30 gsm to about 70 gsm, and comprises polypropylene fibers having an average fiber diameter of from about 2 microns (μm) to about 20 μm;
- and
- (c) one or more additives in the outer abrasive layer (a), the second fabric (b), or both (a) and (b), wherein the one or more additives comprise a colorant, a scent-producing agent, a surfactant, an antimicrobial agent, or a combination thereof.
