11497660 · 2022-11-15 · ·

A method for manufacturing a composite sheet includes a first step of, in a state that a curved part of a first sheet whose one surface rises and whose another surface is recessed and that a second sheet is overlaid on the first sheet, revolving a first roller to convey the first sheet and the second sheet; a second step of passing the sheets between the first roller and a second roller revolving so that a pressing part protruding outward in the radial direction from the outer peripheral surface of the second roller is inserted into the recess of the first roller; forming, in a region within the second sheet opposing the curved part, a protruding part which is surrounded by a flat part; and a third step of joining a boundary part of the first sheet to the second sheet.

ABSORBENT ARTICLE WITH AN EXUDATE MANAGEMENT LAYER

An absorbent article can have a topsheet layer, a liquid impermeable layer, and an absorbent core positioned between the topsheet layer and the liquid impermeable layer. The absorbent article can further include an exudate management layer in fluid communication with the topsheet layer. In various embodiments, the exudate management layer can be positioned on a body facing surface of the topsheet layer. In various embodiments, the exudate management layer can be positioned between the topsheet layer and the absorbent core. The exudate management layer has a first component which defines an opening for direct passage of body exudates into the absorbent core. The exudate management layer has a second component which at least partially overlaps the first component of the exudate management layer and further extends in the longitudinal direction of the absorbent article in a direction towards the posterior region of the absorbent article.

To provide a pad that folds in three in the front-back direction maintaining the shapes of a large number of convex portions protruding on a front-face sheet that prevents the deterioration of liquid diffusibility. The left front side portion and the left back side portion are folded inward with a first left side folding line which is extending in the front-back direction as the center for the folding and which is provided close to the left side with respect to the left side narrowing edge, and the right front side portion and the right back side portion are folded inward with a first right side holding line which is extending in the front-back direction and which is provided close to the right side with respect to the left side narrowing edge.

Process for producing nonwoven and apparatus suitable therefor

The present invention relates to a process and an apparatus for making a fibrous web comprising a plurality of first areas comprising hydroentangled fibers, the first areas being discrete in a machine direction and/or a counter-machine direction, wherein the process comprises subjecting a fibrous web to a first hydroentanglement process directing water jets from a water injection means comprising a plurality of orifices on to the fibrous web; blocking at least one water jet from the water injection means discontinuously by use of a first blocking member positioned between the water injection means and the fibrous web.

Multi-layer material for use in an absorbent article

An absorbent article which can have an improved vertical absorption capability in the depth direction of the absorbent article. The absorbent article can have a topsheet layer, a backsheet layer, and an absorbent system positioned between the topsheet layer and the backsheet layer. The absorbent system can have at least a fluid intake layer and an absorbent core. The fluid intake layer can provide the absorbent article with a raised portion which can improve the vertical absorption capability in the depth direction of the absorbent article.
