Disclosed is an absorbent article having, on its skin contact side, a sheet 2 having a region where, when rubbed under the conditions below, a friction coefficient or a mean deviation of the friction coefficient decreases by 5% or more or 15% or more, respectively, compared to before the rubbing. The absorbent article has a longitudinal direction X corresponding to the front-to-back direction of a wearer and a lateral direction Y. Conditions: A wet collagen film is reciprocated 10 times on the sheet in the longitudinal direction of the sheet under a load of 3.0 kPa; and the wet collagen film has a water content of 100 to 150 mass % relative to the dry weight thereof and is prepared by immersing a collagen film (EDCOL-R, available from PRIRO) cut out into a square of 10 cm in ion-exchanged water for 1 minute, taking out the collagen film, and removing excess water.

Absorbent article with function-formed topsheet, and method for manufacturing

An absorbent article is disclosed. The article includes a topsheet formed of a section of formed nonwoven web material having an ordered arrangement of zones, each zone comprising one or more attenuated regions adjacent to one or more built-up regions, wherein the attenuated regions have a first average basis weight and the built-up regions have a second average basis weight, wherein the first average basis weight is less than the second average basis weight, the difference in basis weights corresponding to disposition of the filaments according to the ordered arrangement. The attenuated region(s) may include a plurality of discrete low bulk portions arranged in a pattern disposed along a longitudinal axis of the article, which facilitate z-direction movement of fluid through the topsheet and inhibit spreading of a fluid stain along the topsheet in the x and y directions.

MULTI-LAYERED NON-WOVEN STRUCTURE FOR USE AS A COMPONENT OF DISPOSABLE ABSORBENT ARTICLES
20210322232 · 2021-10-21 · ·

The present invention relates to multi-layered non-woven structures being useful as components of disposable absorbent articles and garments comprising super absorbent particles and thereby acts as a core. The invention thereby ensures that the body fluids can penetrate from a first layer, which acts as an acquisition layer, up to a third layer comprising SAP particles, the second non-woven layer serving to decrease the fluid volume per surface unit, as a conventional dispersion layer. However the second layer of the invention additionally acts like a non-return valve, preventing, or at least strongly limiting, any fluid transfer from the third layer to the first layer. Channels free of SAP can additionally be design to improve the inlet and rewet properties of the multilayer acquisition and distribution sheet non-woven material.
