Abstract
Absorbent articles containing dark-tinted nonwoven webs are provided. The dark-tinted nonwoven web may include a first plurality of filaments having a diameter between a between about 8 μm and about 50 μm, wherein the first plurality of filaments includes a pigment. The dark-tinted nonwoven web may include a second plurality of filaments having a diameter between about 0.3 μm and about 5 μm. The first plurality of filaments and/or the second plurality of filaments may include crimped filaments. The dark-tinted nonwoven web may have a CIE L* value of between about 0 and about 25, as measured from a first side or a second side of the nonwoven web.
Claims23
An absorbent article comprising:
- a topsheet;
- a backsheet;
- an absorbent core disposed between the topsheet and the backsheet;
- and
- a pair of barrier cuffs extending longitudinally along sides of the absorbent article,
- each of the pair of barrier cuffs comprising a nonwoven web comprising:
- a first plurality of filaments having a diameter between about 8 μm and about 50 μm according to the Filament Size Test, wherein the first plurality of filaments comprises a pigment;
- and
- a second plurality of filaments having a diameter between about 0.3 μm and about 5 μm according to the Filament Size Test;
- wherein the first plurality of filaments and/or the second plurality of filaments comprise crimped filaments;
- wherein the nonwoven web comprises a first side and an opposing second side, wherein the first side forms at least a portion of a wearer facing surface of the barrier cuff and the second side forms at least a portion of a garment facing surface of the barrier cuff, wherein the first plurality of filaments forms a portion of the first side and wherein the first plurality of filaments forms a portion of the second side;
- and
- wherein the nonwoven web has an L* value of between about 21 and about 25 as measured from the first side and an L* value of between about 25 and 50 as measured from the second side, according to the CIE L*a*b* Test, wherein the L* value as measured from the first side is different from the L* value as measured from the second side;
- wherein the nonwoven web has a First Filament Ratio of a number of filaments of the first plurality of filaments as measured from the first side to a number of filaments of the first plurality of filaments as measured from the second side is between about 1.5 to 1 and about 4 to 1, according to the Filament Ratio Test.
