Abstract
Absorbent articles, such as channeled core diapers, including (i) a topsheet; (ii) an acquisition distribution layer (ADL) comprising a first spunbond nonwoven comprising a first plurality of hydrophilic polyolefin fibers, wherein the ADL has a basis weight from about 5 to about 20 grams-per-meter-squared (gsm), such as at least about any of the following: 5, 6, 7, 8, 9, 10, 11, and 12 gsm, and/or at most about any of the following: 20, 19, 18, 17, 16, 15, 14, 13, and 12 gsm; and (iii) an absorbent core including (a) a core warp layer and (b) one or more channels defining one or more troughs, wherein the ADL is located directly or indirectly between the topsheet and the core wrap layer of the absorbent core.
Claims20
An absorbent article, comprising:
- (i) a topsheet;
- (ii) an acquisition distribution layer (ADL) comprising a first spunbond nonwoven fabric comprising a first plurality of hydrophilic polyolefin fibers, wherein the ADL has a basis weight from about 5 to about 20 grams-per-meter-squared (gsm);
- (iii) an absorbent core, wherein the ADL is located directly or indirectly between the topsheet and the absorbent core.
An absorbent article, comprising:
- (i) a topsheet;
- (ii) an acquisition distribution layer (ADL) comprising a first nonwoven fabric comprising a Sx-My-Sz construction, wherein (a) ‘x’ has a value from 1-10, (b) ‘y’ has a value from 1-10, and (c) ‘z’ has a value from 1-10;
- the first nonwoven fabric comprises a first plurality of hydrophilic polyolefin fibers, wherein the ADL has a basis weight from about 5 to about 18 grams-per-meter-squared (gsm);
- (iii) an absorbent core including (a) a core warp layer and (b) one or more channels defining one or more troughs, wherein the ADL is located directly or indirectly between the topsheet and the core wrap layer of the absorbent core.
An absorbent article, comprising:
- (i) a topsheet;
- (ii) an acquisition distribution layer (ADL) comprising a first spunbond nonwoven fabric or first spunmelt nonwoven fabric comprising a first plurality of hydrophilic polyolefin fibers, wherein the ADL has a basis weight from about 5 to about 20 grams-per-meter-squared (gsm);
- (iii) an absorbent core including (a) a core warp layer and (b) one or more channels defining one or more troughs, wherein the ADL is located directly or indirectly between the topsheet and the core wrap layer of the absorbent core.
A method of making an absorbent article, comprising:
- (i) providing or forming a topsheet;
- (ii) providing or forming an acquisition distribution layer (ADL) comprising a first spunbond nonwoven comprising a first plurality of hydrophilic polyolefin fibers, wherein the ADL has a basis weight from about 5 to about 20 grams-per-meter-squared (gsm);
- (iii) providing or forming an absorbent core;
- (iv) directly or indirectly bonding the topsheet to a first surface of the ADL;
- (v) directly or indirectly bonding the absorbent core to a second surface of the ADL, wherein the ADL is located directly or indirectly between the topsheet and the absorbent core.
