Absorbent Articles with Channels

摘要

The present disclosure is directed, in part, to an absorbent article that comprises an absorbent core disposed at least partially intermediate a topsheet and a backsheet and a core wrap enclosing an absorbent material. The core wrap comprises a first material and a second material. The first material forms a C-wrap at least partially around the second material. The absorbent material comprises at least 80% of superabsorbent polymers by weight of the absorbent material. The absorbent core comprises a channel substantially free of the superabsorbent polymers, at least partially oriented in a longitudinal direction of the article, and comprising an arcuate portion. The channel has lateral widths taken parallel to a lateral axis of the article. The profile of the lateral widths of the channel over a longitudinal length of at least 50 mm of the channel taken along the longitudinal axis is substantially constant.

主权项

1. An absorbent article comprising:
a front waist edge; a rear waist edge longitudinally opposing the front waist edge; a first side edge; a second side edge laterally opposing the first side edge; a longitudinal axis extending from a midpoint of the front waist edge to a midpoint of the rear waist edge; a lateral axis extending from a midpoint of the first side edge to a midpoint of the second side edge; a liquid permeable topsheet; a liquid impermeable backsheet; a pair of barrier leg cuffs extending at least partially between the front waist edge and the rear waist edge on opposite sides of the longitudinal axis, wherein each barrier leg cuff comprises:
a proximal edge joined to the topsheet or the backsheet; anda free terminal edge; and an absorbent core disposed at least partially intermediate the topsheet and the backsheet and comprising a core wrap enclosing an absorbent material, wherein the core wrap comprises a first nonwoven and a second nonwoven, wherein the first nonwoven forms a C-wrap at least partially around the second nonwoven, wherein the absorbent material comprises at least 80% of superabsorbent polymers by weight of the absorbent material, wherein the absorbent core comprises a channel substantially free of the superabsorbent polymers, at least partially oriented in the longitudinal direction of the article, and comprising an arcuate portion, wherein the channel has lateral widths taken parallel to the lateral axis, and wherein a profile of the lateral widths of the channel over a longitudinal length of at least 50 mm of the channel taken along the longitudinal axis is substantially constant.
