Claims20
A nonwoven fabric, comprising:
- a first nonwoven layer comprising a first meltblown layer comprising a first plurality of meltblown fibers comprising meltblown shot, meltblown ropes, or both, wherein the meltblown shot, the meltblown rope, or both is randomly and irregularly distributed throughout the first meltblown layer, on a first outer surface of the first meltblown layer, or both, and the first meltblown layer comprises a first polymeric material including (i) a first polymer component and (ii) optionally one or more first additives, wherein the first polymer component comprises a first recycled-polypropylene (rPP).
A method of making a nonwoven fabric, comprising:
- (a) forming a first polymeric melt comprising (i) a first polymer component and (ii) optionally one or more first additives, wherein the first polymer component comprises a first recycled-polypropylene (rPP);
- (b) producing a first nonwoven layer comprising a first meltblown layer, the first meltblown layer comprising a plurality of first meltblown fibers comprising meltblown shot, meltblown ropes, or both;
- and
- (c) consolidating the plurality of first meltblown fibers to form the nonwoven fabric,
- wherein the meltblown shot, the meltblown rope, or both is randomly and irregularly distributed throughout the first meltblown layer, on a first outer surface of the first meltblown layer, or both.
