Method for manufacturing absorbent body
A absorbent member manufacturing method of the invention is a method for manufacturing an absorbent member (100) including synthetic fibers (10b). The method involves: a transporting step of transporting a plurality of sheet fragments (10bh) including synthetic fibers (10b) to an accumulating depression (41) by using a duct 3; an accumulating step of accumulating, in the accumulating depression (41), the plurality of sheet fragments (10bh) transported in the transporting step, and forming an accumulation (100a′) which is a constituent member of the absorbent member (100); and a pressing step of pressing the accumulation (100a′) over its entirety in the thickness direction.
Methods and apparatuses for assembling elastic laminates with different bond densities for absorbent articles
The methods herein relate to assembling an elastic laminate with a first elastic material and a second elastic material bonded between first and second substrates. During assembly, an elastic laminate may be formed by positioning the first and second substrates in contact with stretched central regions of the first and second elastic materials. The elastic laminates may include two or more bonding regions that may be defined by the various layers or components of the elastic laminate that are laminated or stacked relative to each other. In some configurations, a first plurality of ultrasonic bonds are applied to the elastic laminate to define a first bond density in the first bonding region, and a second plurality of ultrasonic bonds are applied to the elastic laminate to define a second bond density in the second bonding region, wherein the second bond density is not equal to the first bond density.
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, wherein said absorbent core comprises at least one core wrap substrate enclosing said absorbent material, and wherein a top layer of said core wrap is adhered to a bottom layer of said core wrap to form one or more channels substantially free of said absorbent material, wherein said channels have 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 channels is from 10% to 95% of the length of said absorbent core and wherein said channels each follow a substantially continuous path such as from a first end of a channel to a second end of the same channel 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/m.sup.2.
Garment-facing laminates and methods for making the same
An absorbent article including a liquid permeable topsheet on a wearer-facing side of the absorbent article and a garment-facing laminate on a garment-facing side of the absorbent article is disclosed. The garment-facing laminate includes a backsheet film and a nonwoven layer joined to the backsheet film. The nonwoven layer defines a plurality of apertures. At least 3 of the plurality of apertures in a repeat unit have a different Effective Aperture Area, according to the Aperture Test herein, a different shape, and a different Absolute Feret Angle, according to the Aperture Test herein. The absorbent article includes an absorbent core disposed at least partially intermediate the liquid permeable topsheet and the garment-facing laminate.
MANUFACTURING METHOD FOR AN ABSORBENT ARTICLE COMPRISING A POCKET AND ABSORBENT ARTICLE BEING PRODUCIBLE THEREBY
A manufacturing method is provided. According to a first step (100), the method comprises providing a backsheet layer, a cover strip layer, and an absorbent core layer in order to manufacture an absorbent article comprising a pocket being accessible from the non-absorbent side of the absorbent article. Then, according to a second step (101), the method comprises cutting an opening into the backsheet layer. In this context, the cutting is speed-synchronized with respect to the provision of the backsheet layer in such a manner that the opening is placed at the same position for every absorbent article. Furthermore, according to a third step (102), the method comprises placing the cover strip layer between the backsheet layer and the absorbent core layer.
METHOD AND APPARATUS FOR ASSEMBLING ABSORBENT ARTICLES
The present disclosure relates to methods and apparatuses for assembling elastic laminates that may be used to make absorbent article components. Particular aspects of the present disclosure include providing a first substrate and a second substrate, the first substrate and the second substrate, each having a width in a cross direction; providing an elastic material; elongating the activated elastic material using a spreader mechanism; and ultrasonically bonding the first substrate together with the second substrate with the elongated activated elastic material positioned between the first substrate and the second substrate using an anvil and an ultrasonic device.
MATERIALS AND METHODS OF MANUFACTURING RELATED TO APPARATUS FOR COLLECTING URINE
The present disclosure provides improvements related to the following: (1) various materials for use in the external permeable wicking cover (outer bandage covering); (2) the placement of a shape retention element within an edge seam of the core wherein the shape retention element has rolled ends to prevent any sharp ends; and (3) various production improvements related to heat blooming of core for shape retention, continuous processing of the external covering and core, automatic cutting to length during production, vacuum hold for insertion of the core into the outer impermeable housing, and heat mold gluing/forming of the outer covering to the inner core.
ABSORBENT INSERTS FOR TOOTH CAVITIES
An absorbent insert of compressed matrix of absorbent material, including a filler dispersed therein to improve stiffness/rigidity of the insert and controls the absorbency of the compressed absorbent material. The insert is pre-shaped and sized for inserting into a tooth cavity, such as a pulp chamber or a root canal space. The compressed insert expands or swells upon absorbing fluid within the tooth cavity, so as to more completely dry the tooth cavity. The absorbent insert also serves as a substrate of an applicator for medical agent to be applied to a tooth cavity. The absorbent insert is provided (e.g., coated or impregnated) with a medical agent, which medical agent is released into the tooth cavity as the absorbent material absorbs fluid in the tooth cavity.
Absorbent structure
