Abstract

The invention relates to an absorbent article that comprises a barrier component, which comprises a nonwoven barrier sheet, comprising at least a spunbond nonwoven web with spunbond fibers and at least a meltblown nonwoven web with meltblown fibers (or at least two nonwoven laminate layers comprising said meltbown and spunbond webs), and whereby said nonwoven barrier sheet has pores of a largest pore size of less than 50 microns, and whereby said spunbond fibers have a number average diameter of 6 to 18 microns, 11 microns or 12 to 14 microns or 15 microns, and whereby the total weight percentage (by weight of the nonwoven barrier sheet) of the meltblown web(s) is from 5% to 30%, 5% to 20%, and whereby said meltblown fibers have a number average fiber diameter from 1 [mu]m to 5 [mu]m, or from 1 [mu]m to 3 [mu]m.

Description

field of invention [0001] The present disclosure relates to an absorbent article comprising a barrier assembly comprising at least one spunbond fiber comprising spunbond fibers, and may include a backsheet, an absorbent core and a core cover sheet, the barrier component comprising a nonwoven barrier sheet Nonwoven webs and at least one meltblown nonwoven web comprising meltblown fibers present at a selected level and having a specified fiber size and denier, the nonwoven barrier sheet having a specified maximum pore size hole. Background of the invention [0002] Providing absorbent articles such as sanitary napkins and diapers with liquid barrier components (e.g. side flaps, leg cuffs, barrier cuffs) or for example with anal and / or genital cuffs (also referred to as topsheets with one or more openings) is based on well known in the field. These cuffs have a high barrier function to prevent bodily exudates from wetting the skin or leaking out of the absorbent article. [...
