摘要:
An absorbent article with improved body fit wherein a combination of downward-deflecting crease lines and an upward-deflecting shaping line are used in outer and central absorbent members, respectively, to achieve a form-fitting geometry in the crotch region while also enhancing control over fluid flow in the article. Embodiments with wicking barriers between the outer and central absorbent members are especially useful in achieving leakage reduction.
摘要:
An absorbent article comprising a central absorbent member and a lateral wicking barrier for inhibition of wicking from the central regions of the article to an outlying outer absorbent member. The wicking barrier has a vertical component for prevention of radial wicking in the plane of the article and thus promotes center filling of the article with fluid and reduces the likelihood of leaks from the sides of the article. The wicking barrier can also have a horizontal component to prevent leakage, redirect fluid flow, and improve fit and performance of the article. In one embodiment, the central absorbent member is a concentric absorbent structure having alternating rings of barrier material and absorbent material, including a spiral wound composite formed from a layer of barrier material wound with a layer of absorbent material and then sliced.

In one embodiment, the central absorbent member is a concentric absorbent structure having alternating rings of barrier material and absorbent material, including a spiral wound composite formed from a layer of barrier material wound with a layer of absorbent material and then sliced to provide a thin absorbent layer having high permeability in the thickness direction but low permeability in the plane due to the barrier material.

Absorbent articles comprising fibrous nits and other free-flowing particles are disclosed. In one embodiment, an absorbent article is disclosed comprising free-flowing particles in a central portion which, in conjunction with other absorbent members, provides excellent body fit and good fluid handling performance. In another embodiment, good leakage control is provided by the combined effect of good intake and fluid handling performance of fibrous nits coupled with a wicking barrier between the nits and the longitudinal sides of the articles. An optional central rising member can further enhance the topography of the article when compressed by urging the portion comprising nits to deflect vertically upward.Methods of preparing cellulosic nits and incorporating them into absorbent articles are also described.
摘要:
Free flowing particles useful in absorbent articles are disclosed, including fibrous nits and methods of preparing fibrous nits. In one embodiment, fibrous nits are prepared from disperging cellulosic fibers in the presence of a nit conditioner which modifies nit particle size and properties for improved performance of the particles. In other embodiments, nits are prepared in multiple disperging steps or by disperging fibers under two or more conditions.

摘要:
A composite absorbent article comprises a reusable frame member for shaping and leakage control onto which a single-use absorbent device can be detachably connected and repeatedly replaced without the need to replace the reusable frame member. A low-cost, high-performance composite absorbent article can thus be provided from low-cost single-use absorbent devices by virtue of the reusable frame member. A wicking barrier lining a central void or depression helps provide leakage containment for the overall composite absorbent article.
摘要:
An absorbent article is disclosed comprising a unitary absorbent layer having a central portion and an outer portion divided in part but not completely separated by one or more slits along a boundary surrounding the outer portion, further comprising a wicking barrier along at least a portion of the boundary. The central portion and outer portion of the unitary absorbent layer remain contiguous across one or more joining zones. A central rising member can be disposed beneath the central portion of the unitary absorbent layer to urge the central portion toward the body of the user when compressed laterally inward. The article is able to achieve good center-fill performance when in use and maintain excellent body fit.
摘要:
An absorbent article is disclosed having excellent body fit, center-fill fluid handling performance, and good leakage control in that flow from the center of the article to the longitudinal sides thereof is hindered by a wicking barrier. The article comprises a lower absorbent member, an horizontal wicking barrier over the lower absorbent member, and a central absorbent section forming a medial hump over the horizontal wicking barrier. An optional central rising member can further enhance the topography of the article when compressed by urging a central portion to deflect vertically upward. In one embodiment, longitudinal upward projections on the horizontal wicking barrier also help control the deformation of the article for good body fit.
