An absorbent article (10, 110, 210) can include an absorbent assembly (43) including a bodyside liner (28), an outer cover (26, 126, 226), and an absorbent body (35) disposed between the bodyside liner (28) and the outer cover (26, 126, 226). The outer cover (26, 126, 226) can include at least one opaque region (64, 164, 264) and a first indicator region (66, 166, 266). The first indicator region (66, 166, 266) can have a light transmittance that is greater than a light transmittance of the at least one opaque region (64, 164, 264). At least a portion of the first indicator region (66, 166, 266) can be located between the first longitudinal edge (36) of the absorbent body (35) and the first coupling length (45) of the first containment flap (44) in at least the crotch region (16) of the absorbent article (10, 110, 210).

A manufacturing apparatus for an absorbent body including: a first conveyor that conveys an air-permeable first sheet while sucking the first sheet along a flat first slope surface; a second conveyor that conveys an air-permeable second sheet while sucking the second sheet along a flat second slope surface having a slope opposite to the first slope surface; a first distribution device that forms a first absorbent layer in the first sheet by distributing absorbent powder on an upper surface of the first sheet being conveyed along the first slope surface; a second distribution device that forms a second absorbent layer in the second sheet by distributing absorbent powder on an upper surface of the second sheet being conveyed along the second slope surface; and a stacking part that stacks the first sheet conveyed by the first conveyor and the second sheet conveyed by the second conveyor in such a manner as to cause the first absorbent layer of the first sheet and the second absorbent layer of the second sheet to face each other.

A device for producing an absorbent body includes crushers that are each configured to crush a supplied pulp sheet into fluff pulp and that each include a plurality of rotating blades, a duct in which the fluff pulp is carried by air, and a rotating fiber stacking drum that includes an adsorbent molding section that molds the fluff pulp carried by air from the duct into an absorbent body with a desired shape. Further, the crushers are staggered in an axis direction of the rotating blades.

A separating device separates liquid absorbent fibers from a material including the liquid absorbent fibers of an absorbent article and impurities. The separating device includes: a case; an insertion port for inserting the material into the case on an airflow; a rotation member in the case for agitating and opening the material; and a discharge port for discharging the liquid absorbent fibers from inside the case on an airflow. The rotation member has a revolving axis with an axial direction along a predetermined direction from the insertion port to the discharge port, and a shaft member rotating around a rotating axis that has been set with an axial direction along the predetermined direction, while revolving around the revolving axis. The shaft member has protruding sections protruding outward and intersecting with an axial direction of the shaft member.

Pulpless absorbent cores and methods of manufacture are disclosed. A first exemplary absorbent core may comprise a carrier sheet having a first edge region, a central region, and a second edge region and particulate material disposed on the carrier sheet through the first edge region, the central region, and the second edge region. The absorbent core may additionally have an absorbent core width and the central region may have a central region width, and the central width may comprise between 33% and 75% of the absorbent core width. Further, the central region may comprise an average basis weight of particulate material that is at least 110% of an average basis weight of particulate material within at least one of the left edge region and the right edge region.

Material webs suitable for use in conjunction with disposable absorbent articles are disclosed herein. The material webs comprise a melt additive that when subjected to thermal energy may be encouraged to bloom across the entirety of the web or in localized areas of the web where localized thermal energy is applied.

A water repellent is applied to a spun lace nonwoven fabric in which a surface sheet comprises 100% by weight of cotton fibers, and a large number of openings that penetrate the obverse and reverse surfaces are formed in at least a portion that corresponds to an excretory opening. A heat-fusible fiber sheet is disposed adjacent to the absorber side surface of the surface sheet. A plurality of adhesive portions are formed between the surface sheet and the heat-fusible fiber sheet along the longitudinal direction and spaced apart in the widthwise direction of an incontinence pad. A compressed groove recessed from the outer surface of the surface sheet toward the absorber is formed close to the adhesive portions.

Material webs suitable for use in conjunction with disposable absorbent articles are disclosed herein. The material webs comprise a melt additive that when subjected to thermal energy may be encouraged to bloom across the entirety of the web or in localized areas of the web where localized thermal energy is applied.

A method for making a disposable absorbent article is provided. The method comprises the steps of providing a first nonwoven comprising synthetic fibers comprising a .sup.14C/C ratio of about 1.0×10.sup.−14 or greater, providing a second nonwoven comprising synthetic fibers comprising a comprising a .sup.14C/C ratio of about 1.0×10.sup.−14 or greater, converting the second nonwoven into a topsheet so that the topsheet comprises a Liquid Strike Through value of less than 4 seconds, and combining the first nonwoven and the topsheet with other absorbent article components to form a disposable absorbent article.
