Claim 18:
19. A spunbond non-woven fabric comprising a plurality of fibers, wherein the fibers are formed from a polymer blend comprising at least one first polymer and at least one second polymer,
wherein a melt flow rate (MFR) of the at least one first polymer is greater than a MFR of the at least one second polymer,
wherein the MFR of the at least one second polymer is from 9 g/10 min to less than 18 g/10 min,
wherein the MFR of the at least one first polymer is from 18 g/10 min to 40 g/10 min, wherein the polymer blend comprises a percentage by weight of the second polymer that is greater than a percentage by weight of the first polymer,
wherein the polymer blend comprises 20-30% by weight of the first polymer,
wherein the fibers each comprise a fiber body that surrounds and defines a cavity,
wherein the fiber body and the cavity together define a total volume, and
wherein the fibers comprise a hollowness of greater than 0% up to about 25% by volume of the total volume.
