Absorbent article

The present invention addresses the problem of providing an absorbent article that has an improved ability to transfer menstrual blood from a liquid-permeable layer to an absorbent body and can reduce the amount of the menstrual blood remaining in the liquid-permeable layer. To solve this problem, provided is a sanitary napkin provided with a top sheet, a back sheet and an absorbent body that is interposed between the top sheet and the back sheet, wherein convex portions formed in an excretion orifice contact region of the top sheet are coated with a blood lubricity-imparting agent that has a kinetic viscosity of 0.01-80 mm.sup.2/s at 40° C., a water retention rate of 0.01-4.0 mass % and a weight-average molecular weight of less than 1,000.

Formed web comprising chads

A formed web comprising discrete three-dimensional elements formed therein, wherein at least some of the discrete three-dimensional elements comprise chads with corresponding apertures, wherein the aperture has a perimeter, wherein the chad has a length, wherein the chads are attached along a portion of the aperture perimeter which forms a connection segment, wherein the connection segment is less than about 50% of the entire aperture perimeter, and wherein the web comprises a film.

Perforated non-woven fabric and its manufacturing method

A perforated non-woven fabric having at least one fiber layer that has a plurality of through holes. The total area of the through holes accounts for 10˜80% of the total area of the perforated non-woven fabric; the opening of the through holes is flat with the surface of the perforated non-woven fabric; and the density of through holes on the perforated non-woven fabric is 3/cm.sup.2˜100/cm.sup.2. The fiber density at the edge of each through hole is similar to or the same as the fiber density in other areas of the perforated non-woven fabric. The fiber surrounds the through hole, and only the surface of the fiber is bonded to each other.

Laminates for absorbent articles and methods of making the same

Three-dimensional laminates and methods for making the same are provided. The three-dimensional laminates may be apertured and may have welds between various substrates. The three-dimensional laminates may be used in absorbent articles, such as diapers and pants, for example, as topsheets, as topsheets and acquisition layers, or as outer cover materials, for example. The three-dimensional laminates may be produced on an absorbent article manufacturing line.

ABSORBENT ARTICLE COMPRISING A TOPSHEET/ACQUISITION WEB LAMINATE

An absorbent article for personal hygiene comprises a longitudinal axis, a transversal axis perpendicular to the longitudinal axis, a topsheet/acquisition web laminate, a liquid impermeable backsheet, and an absorbent core. The absorbent core is located between the topsheet/acquisition web laminate and the backsheet. The topsheet/acquisition web laminate comprises a liquid permeable topsheet and an acquisition web in a face to face relationship. The topsheet/acquisition web laminate comprises three-dimensional protrusions extending from a plane of the topsheet/acquisition web laminate. The acquisition web is a nonwoven fibrous web comprising an upper layer facing towards the topsheet and a lower layer facing towards the absorbent core. The average diameter of the fibers in the upper layer is higher than the average diameter of the fibers in the lower layer.

Compositioned, Textured Nonwoven Webs

Disclosed herein are textured nonwoven webs suitable for use in disposable absorbent articles. The textured nonwoven webs have a generally planar first region and a plurality of integrally formed discrete second regions. The textured nonwoven webs also have at least one composition disposed on at least one of the first region or the plurality of discrete second regions.
