Disposable diaper with inlet cutting part on skin contact layer
10940054 · 2021-03-09 ·

The present invention relates to a disposable diaper for absorbing and receiving excreted urine and feces, The diaper includes a base layer including an absorber and a cover layer positioned at an upper end of the absorber. A skin contact layer is positioned at an upper end of the base layer so as to cover the cover layer, having an inlet cutting part cut in a predetermined length such that urine and feces reach the cover layer or the absorber.

TOPSHEETS FOR ABSORBENT ARTICLES

A disposable absorbent article includes a topsheet, a backsheet, and an absorbent structure positioned intermediate the topsheet and the backsheet. The topsheet includes an elongate central portion and two wing portions opposingly laterally extending from the elongate central portion. The topsheet forms a wearer-facing surface in the two wing portions. The topsheet includes one or more continuous channel-forming structures following one or a plurality of paths. The one or plurality of paths is substantially symmetric about a central longitudinal axis of the topsheet and predominately circumscribes a discharge locus on the central longitudinal axis of the topsheet. The one or more continuous channel-forming structures extends across a central lateral axis of the topsheet. The topsheet includes a continuous hinge forming structure following a path extending generally longitudinally along one of the wing portions and extending across the central lateral axis of the topsheet.

Perforated non-woven fabric and production method thereof

Provided are a perforated non-woven fabric and a production method thereof. The perforated non-woven fabric is formed by overlapping three-dimensional funnel-shaped openings of two perforated non-woven fabric layers. The first perforated non-woven fabric layer has a protruding portion and a recessed portion. The protruding portion has an internal space. An upper side of the second perforated non-woven fabric layer is adhered to a lower side of the recessed portion of the first perforated non-woven fabric layer. The overlapped three-dimensional funnel-shaped openings pass through the first perforated non-woven fabric layer and the second perforated non-woven fabric layer. An air flow passage is formed between continuous internal spaces of the protruding portions of the first perforated non-woven fabric layer and the second perforated non-woven fabric layer, thereby facilitating penetration of liquid and soft feces, reducing residues, enabling internal and external air flow circulation, and reducing discomfort from wetness.

PROCESS FOR MAKING AN ABSORBENT ARTICLE COMPRISING A TOPSHEET/ACQUISITION LAYER LAMINATE

A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an intermediate layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The intermediate layer has a first and second surface. The topsheet and intermediate layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the intermediate layer and simultaneously mechanically deformed which combines the topsheet with the intermediate layer. The topsheet web and intermediate layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the intermediate layer to provide a topsheet/intermediate layer laminate web having three-dimensional protrusions.

A disposable absorbent article, having a front-back direction that is perpendicular to a width direction and a thickness direction that extends from a skin contact surface side to a non-skin contact surface side of a wearer, includes: an absorbent constituent; a liquid-permeable topsheet that is disposed on the skin contact surface side of the absorbent constituent; and a leakage-preventing sheet that is disposed on at least one of an outside, in the thickness direction, of the absorbent constituent, and an outside, in the width direction, of the absorbent constituent. The leakage-preventing sheet includes a water repelling layer including a nonwoven fabric. The nonwoven fabric of the water repelling layer includes fiber and has an average fiber diameter of 0.5 to 10 m. The water repelling layer includes a water repelling section where a group of particles adhere to a surface of the fiber.

Configurable Absorbent Articles

Configurable absorbent articles are provided. The absorbent articles may comprise a topsheet, a backsheet, and an absorbent core positioned at least partially intermediate the topsheet and the backsheet. The absorbent articles may comprise a first waist region, a second waist region, a crotch region extending intermediate the first waist region and the second waist region, and an outer cover material joined to the backsheet and forming a portion of a garment-facing surface of the absorbent article. The absorbent articles may comprise a pair of leg cuffs and a fully removable fastening member. The fastening member may comprise a first fastener on a first surface of the fastening member and positioned proximate to a first end and a second fastener on the first surface and positioned proximate to a second end. The absorbent articles may also comprise a wetness guard.

Method for manufacturing topsheets for absorbent articles

Methods for manufacturing topsheets for absorbent articles are disclosed. The methods may include: providing a cycling forming belt that includes an air-permeable substrate and an ordered arrangement of airflow blocking structures thereon; directing air flow with entrained fibers and/or filaments to a working location through which the belt cycles; drawing the air flow through airflow permeable regions of the belt as they cycle through the working location, and thereby drawing the fibers/filaments to the belt such that they accumulate thereon to form a batt having an arrangement of built-up regions and attenuated regions corresponding with the arrangement of blocking structures, wherein the structures are arranged in individualized single-topsheet configurations that repeat along the machine direction, each configuration being adapted to form a section of web material for a topsheet and to impart a desired formation thereto including channel portions, hinge portions and/or pattern(s) of discrete low bulk portions.

Process for making an absorbent article comprising a topsheet/acquisition layer laminate

A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an acquisition layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The acquisition layer has a first and second surface. The topsheet and acquisition layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the acquisition layer and simultaneously mechanically deformed which combines the topsheet with the acquisition layer. The topsheet web and acquisition layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the acquisition layer to provide a topsheet/acquisition layer laminate web having three-dimensional protrusions.
