ABSORBENT ARTICLES AND METHODS OF MAKING
An absorbent article comprising an absorbent core sandwiched between a liquid permeable topsheet and a liquid impermeable backsheet, and an acquisition distribution layer positioned between said topsheet and said absorbent core, wherein the absorbent core comprises absorbent material selected from the group consisting of cellulose fibers, superabsorbent polymers and combinations thereof, said absorbent core comprising at least one interconnected channel free of said absorbent material, wherein said channel has a length extending along a longitudinal axis and the absorbent core has a length extending along said longitudinal axis and wherein the length of said channel is from 10% to 95% of the length of said absorbent core wherein the acquisition distribution layer comprises a spunbond and/or carded nonwoven layer comprising synthetic fibers, wherein said synthetic fibers are comprised at a level of greater than 80% wt by weight of said acquisition distribution layer, and wherein said acquisition distribution layer has a basis weight of from 10 to 50 g/m2.
ABSORBENT CORE, ARTICLES COMPRISING SAID CORE, AND METHODS OF MAKING
An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.
Absorbent article
(Object) To prevent leakage of body fluids and to readily transmit pressure from both sides to a center portion in a width direction by bringing an absorbent article into close contact with a crotch area extending from a body fluid discharge portion to a start position of the intergluteal cleft. (Means of Achieving the Object) A pair of right and left compressed grooves (8, 8) that extend in an approximately longitudinal direction is formed on a surface of a liquid permeable top sheet (3). The compressed grooves (8) have separation distance reduced regions (11), in which a separation distance between the right and left compressed grooves is reduced, formed at the back of a region corresponding to a body fluid discharge portion (H) of a wearer, and also have vastly enlarged portions (10), in which widths of the compressed grooves (8) are enlarged, formed at positions within the separation distance reduced regions (11) and where the separation distance between the right and left compressed grooves (8, 8) becomes minimum.
METHOD FOR DETERMINING AND/OR VISUALIZING AIRFLOW THROUGH ABSORBENT CORES AND ABSORBENT ARTICLES EXHIBITING ENHANCED AIRFLOW
A method for measuring airflow through a channel comprised in an absorbent article core, said method comprising the steps of: providing an absorbent core adapted to be sandwiched between a liquid permeable topsheet and a liquid impermeable backsheet of an absorbent article, wherein the absorbent core comprises at least one channel; providing a thermal imaging camera; loading the absorbent core with a warm liquid, wherein said warm liquid has a temperature of greater than 30° C.; simultaneously visually recording said absorbent core with said thermal imaging camera, and spraying said channel(s) with a cold fluid, wherein the cold fluid has a temperature of less than 10° C.
ABSORBENT ARTICLE WITH CHANNELS AND METHOD FOR MANUFACTURING THEREOF
An absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core comprising an absorbent material between a top core wrap sheet and a back core wrap sheet, said absorbent core being positioned in between said topsheet and said backsheet; said absorbent core having a first and second longitudinal edge (131, 132) and a front and rear transverse edge (133, 134), wherein the absorbent core is provided with a plurality of attachment zones where the top core wrap sheet is attached to the back core wrap sheet, wherein the plurality of attachment zones comprises: at least a first and a second elongate attachment zone, said first and second elongate attachment zone extending next to each other from a crotch region in the direction of the front and/or rear transverse edge; at least one connecting attachment zone connecting said first attachment zone with said second attachment zone.
ABSORBENT ARTICLE
To reliably prevent rear leakage. A sanitary napkin includes a plurality of widthwise compressed grooves which are disposed in a region to the rear of a region corresponding to a bodily fluid discharge part H of a wearer, extend in a substantially widthwise direction of the sanitary napkin, are formed in a shape bulging toward the rear, and are arranged at intervals in the longitudinal direction of the sanitary napkin; and a right and left pair of longitudinally compressed grooves which extend along substantially the longitudinal direction of the sanitary napkin and are each arranged on the outside in the width direction at a predetermined separating distance from the widthwise compressed grooves. The widthwise compressed grooves are formed such that the groove widths and lengths thereof become gradually larger as the widthwise compressed grooves are arranged relatively closer to the rear of the sanitary napkin.
Absorbent article
An absorbent body 4 is provided between a liquid permeable topsheet 3 and a liquid impermeable backsheet 2, and a second sheet 6 is provided between the liquid permeable topsheet 3 and the absorbent body 4. Slits 10 that penetrate in the thickness direction are formed along a longitudinal direction on both sides of the absorbent body 4 in the width direction, a body fluid expelling portion corresponding region H is included between the slits, the second sheet 6 is provided along an inner surface of the slits, and concave grooves 11, in which the second sheet 6 and the liquid impermeable backsheet 2 are integrated, are formed in the slits.
