Diaper structure with enhanced tactile softness attributes
A diaper structure with enhanced softness attributes is disclosed. The diaper structure may include an innermost layer formed of a first nonwoven web, and an outermost layer formed of a second nonwoven web. The first and second nonwoven webs may have a combined basis weight of at least about 30 gsm. The ratio of the first web basis weight to the second web basis weight may range from 30/70 to 70/30.
FILMS AND LAMINATES FOR ABSORBENT ARTICLES
A film for use in an absorbent article includes a first side and a second side opposite the first side, and a plurality of apertured protuberances arranged in a pattern having 60 to 120 protuberances per linear inch in at least one direction. Each of the protuberances includes a continuous sidewall extending from the first side. The second side has a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures. The film has a melt index of at least about 8 g/10 min, and an air permeability of at least about 80 m.sup.3/m.sup.2/min.
Apertured webs and methods for making the same
A patterned apertured web includes a plurality of first arrays forming a first zone in the patterned apertured web. At least some of the first arrays include a first plurality of land areas and a first plurality of apertures. At least some of the first plurality of land areas surround at least some of the first plurality of apertures. The first plurality of apertures of the first zone have a plurality of Interaperture Distances, according to the Aperture Test. The Interaperture Distances of the first zone have a first distribution having a first mean and a first median. The first mean is greater than the first median by at least 4%.
SYSTEM OF PANTILINERS AND MENSTRUAL PADS
A system of pantiliners and menstrual pads that can be used to alleviate undesirable conditions associated with dysmenorrhea or other physiological conditions is provided. The pantiliners of the invention include a top layer of composite material, a ventilation layer, and a bottom layer of breathable material. The menstrual pads of the invention include a top layer of composite material, an air-laid layer, a layer of super adsorbent polymer inside the air-laid layer, a ventilation layer, and a bottom layer of breathable material. The present system of pantiliners and menstrual pads is helpful in providing a decrease of pain and other unwanted symptoms during a menstrual cycle. In another advantage, the right placement guide and the left placement guide are provided to assist in placing the menstrual pads of the invention accurately in relation to the undergarment of the user.
Laminate Webs And Absorbent Articles Having The Same
A laminate web having a polymer film layer and a nonwoven layer is disclosed. The polymer film layer makes up a first side of the laminate web and the nonwoven layer makes up a second side of the laminate web. The laminate web has a plurality of first elements extending from the polymer film. The web also has a plurality of second elements formed outwardly from the first side of the laminate web.
APERTURED WEBS AND METHODS FOR MAKING THE SAME
A disposable absorbent article having a topsheet, a backsheet, and an absorbent core disposed therebetween is described. The topsheet has an array of apertures forming apertured indicia. The array of apertures includes a first plurality of apertures having a first aspect ratio; a second plurality of apertures having a second aspect ratio and a first Absolute Feret Angle; and a third plurality of apertures having a third aspect ratio and a second Absolute Feret Angle, wherein the first Absolute Feret Angle and the second Absolute Feret Angle are different, and wherein the first aspect ratio is less than the second and third aspect ratios.
Laminate webs and absorbent articles having the same
A laminate web having a polymer film layer and a nonwoven layer is disclosed. The polymer film layer makes up a first side of the laminate web and the nonwoven layer makes up a second side of the laminate web. The laminate web has a plurality of first elements extending from the polymer film. The web also has a plurality of second elements such as recesses, protrusions, apertures, embossing and combinations thereof.
Absorbent article with a concave groove
A absorbent article has a concave groove that satisfies (1) a relationship between a depth h of a bottom surface portion of the concave groove, and a distance S from a bottom end G of the concave groove to an upper end K from which a concavity of the concave groove starts is 1.5h<S, (2) a relationship between a width b of a bottom surface of the concave groove, and a width B of a liquid collection area expressed by a distance between the upper ends K and K at both sides of the concave groove is B3b, and (3) a relationship between a dimension a of a square concave groove expressed by a product of the width b of the bottom surface and the depth h of the bottom surface, and a cross-sectional dimension A of the concave groove is A2a.
Disposable diaper
An absorbent article includes a stretchable sheet that is a laminate of a non-stretchable first sheet layer, a non-stretchable second sheet layer, and an elastic film disposed between the first and second sheet layers, and the elastic film is stretchable at least in the front-back direction. The first sheet layer is bonded to the second sheet layer at a large number of joints directly or through the elastic film and the joints are arrayed at intervals. The stretchable sheet is contracted by a contraction force of the elastic film and can be stretched by an external force applied in the front-back direction. The leg portion is also contracted by a contraction force of the elastic film and can be stretched by an external force applied in the width direction. The leg portions and adjoined regions have different joint area rates and thereby have different stretching stresses.
Apertured topsheets and methods for making the same
A diaper includes a liquid permeable topsheet including a patterned apertured nonwoven material. The patterned apertured nonwoven material includes a plurality of land areas in the patterned apertured nonwoven material and a plurality of apertures defined in the patterned apertured nonwoven material. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The plurality of apertures are non-homogeneous in a repeat unit such that at least two apertures of the plurality of apertures have a different size or a different shape.
