摘要： Nonwoven fabrics are provided that include a first nonwoven layer comprising a first plurality of fine fibers. The first plurality of fine fibers 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) comprising a visbroken spunbond grade polypropylene having a first melt flow rate (MFR) before visbreaking and second MFR after visbreaking, and wherein the second MFR is larger than the first MFR.
