Absorbent articles with wicking barrier cuffs

An absorbent article is disclosed comprising a thin, flexible wicking barrier with a horizontal portion that is folded back upon itself to create a substantially longitudinal cuff. The wicking barrier can separate a central absorbent member from an outer absorbent member for improved center fill, with the cuff open toward the central absorbent member to intercept liquid flowing toward the longitudinal sides of the article. The wicking barrier cuff desirably contains spacer means to hold the cuff open, providing void space to receive fluid. In one embodiment, lateral compression of the article during use causes the wicking barrier cuff to lift up from the surface of the article, creating a bubble of topsheet material and wicking barrier material (a “dynamic bubble cuff”) that intercepts fluid and improves body fit and leakage prevention.

Center-fill absorbent article with a wicking barrier and central rising member

An absorbent article is disclosed comprising a central absorbent member, an outer absorbent member, and a central rising member for urging the central absorbent member toward the body of the user when compressed laterally inward by the legs of the user. The article is able to achieve good center-fill performance when in use and maintain excellent body fit. Also disclosed is a lateral wicking barrier for inhibition of wicking from the central regions of the article to an outlying outer absorbent member. The combination of a wicking barrier isolating the central absorbent member from the longitudinal sides of the article and a central rising member urging the central absorbent member toward the body yields an article with excellent absorbency and leakage protection.

Macroscopically expanded three-dimensional polymeric web for transmitting both dynamically deposited and statically contacted fluids from one surface to the other

A macroscopically expanded, three-dimensional fluid-handling polymeric web having first and second surfaces located in substantially parallel planes which are remote from one another. The web includes a multiplicity of fluid-handling capillary networks of macroscopic cross-section for rapidly transmitting fluids which are dynamically deposited on the first surface of said web to the second surface of said web using the dynamic and gravitational head of the fluid as a primary driving force. Each of the macroscopic cross-section capillary networks originates as an aperture in the first surface of the web and has a continuously interconnected sidewall extending in the direction of the second surface of said web. The continuously interconnected sidewall terminates to form at least one aperture in the second surface of said web, whereby the bulk of the dynamically deposited fluid is transmitted from the first surface to the second surface of said web by the macroscopic cross-section capillary networks. The first surface of the web in which the macroscopic cross-section capillary networks originate further includes a multiplicity of fluid-handling capillary networks which are substantially smaller in cross-section than the macroscopic cross-section fluid-handling capillary networks. The smaller fluid-handling capillary networks exhibit a degree of capillary suction sufficient to transmit static fluid contained on the surface of objects which contact the first surface of said web generally in the direction of the second surface of said web by capillary attraction.

Multi-layered non-woven structure for use as component of disposable absorbent products

FIELD: layered products. SUBSTANCE: present invention relates to multi-layered non-woven structures used as components of disposable absorbent products and clothing, containing superabsorbing particles and, thus, acting as a core. Thus, the invention provides a possibility of penetration of the biological bodily fluids from the first layer acting as a reception layer into the third layer containing SAP particles, wherein the second non-woven layer serves to reduce the volume of liquid per unit surface as a standard dispersion layer. However, the second layer of the invention additionally acts as a return valve, preventing or at least strongly limiting any transfer of liquid from the third to the first layer. SAP-free channels can be additionally constructed to improve the input properties and the rewetting property of the multi-layered non-woven sheet material with a reception and distribution layer.
