A method of joining substrate portions includes positioning the substrate portions such that the substrate portions overlap at an overlap area. The substrate portions each have a melting temperature and an outer surface. A fluid is heated to a temperature sufficient to at least partially melt the substrate portions. A jet of the heated fluid is directed from a fluid orifice onto the substrate portions at the overlap area. The heated fluid penetrates at least one of the outer surfaces of the substrate portions. The substrate portions are at least partially melted using the heated fluid. The substrate portions are compressed to join the substrate portions together at the overlap area.

An absorbent article includes a chassis having a substantially rectangular shape a first portion, a second portion and a crotch portion extending between the first and second portion, a portion of the chassis being configured to absorb fluids. The absorbent article includes a first securement portion operatively coupled to the first portion of the chassis. The absorbent article includes a second securement portion operatively coupled to the second portion of the chassis and configured to releasably attach to the first securement portion. The chassis is configured to include one of a first chassis length or a second chassis length. When the chassis includes the first length, the chassis includes a first width and the first securement portion includes a second width, and when the chassis includes the second length, the chassis includes the first width and the first securement portion includes a third width, greater than the second width.

An absorbent article with a liquid-permeable topsheet, an absorbent core and a liquid-impermeable backsheet is provided with a liquid-redirecting layer. The liquid-redirecting layer may be a water-repellent layer and is located underneath of the absorbent core. A method of manufacturing of an absorbent article having a water-repellent layer underneath of the absorbent core is described.

In an underpants-type disposable diaper including a waist edge portion in which pleats extend straight and which has excellent fit, the inner layer and the outer layer at the waist edge portion of an outer body are joined by an adhesive arranged intermittently or a welding process performed intermittently in the width direction and continuously in a direction crossing the width direction, thereby forming sheet joined sections, waist edge portion resilient and elastic members are sandwiched between the inner layer and the outer layer and fixed to at least one of the inner layer and the outer layer at positions intersecting with the sheet joined sections, and the diaper includes an area not being joined and not having resilient and elastic member at an end portion of the outer body on the waist opening side in the waist edge portion, the area not having sheet joined sections nor the waist edge portion resilient and elastic members, and a vertical range being wider than spacing between the waist edge portion resilient and elastic member positioned closest to the waist opening side, and the waist edge portion resilient and elastic member adjacent thereto.

Disclosed is an absorbent article for pet animals. The article has a longitudinal direction, a transverse direction, a body-facing surface, a non-body-facing surface and first and second ends opposed to each other in the longitudinal direction. The article includes: a tail facing area facing a pet animal's tail; a first section to cover one side of a pet animal's rump, extending from the tail facing area to the first end; a second section to cover the other side of the pet animal's rump, extending from the tail facing area to the second end; and an absorbent core disposed between the first and second sections.

A unique garment designed to aid healing of minor skin ailments such as diaper rash. A urine absorbent, air flow permeable undergarment (1) may contain a barrier (4) to absorb urine and even an open back (5) such as for example a cutout in the back portion (3) a garment that may maximize airflow to the buttocks and groin. In some embodiments, a garment may not be a diaper and may not be designed to contain multiple urinations. In some embodiments, such as in a reusable form, the garment may be designed with a disposable pad capable of containing one or more urinations, then the disposable pad may be replaced. In yet another embodiment, a disposable garment may be provided so that after urination, the entire garment may be thrown away.

A pants-type disposable diaper includes a pair of strip projecting parts projecting laterally from a line of connection between front and rear parts located respectively on the belly and back sides of a wearer, a first waist elastic member joined to a first waist region that is an upper part of a waist region extending along a waist opening, and a second waist elastic member joined to a second waist region that is a lower part of the waist region. In a state in which an outer covering sheet is elongated in a right-left direction, a first unit contractile force that is a contractile force in the right-left direction per unit width of the first waist region in an up-down direction is smaller than a second unit contractile force in the second waist region.

Disposable absorbent articles assembled from a collection of components using an adhesive comprising an amorphous polyolefin composition and a heterophase polyolefin composition comprising amorphous character and crystalline blocks.

An absorbent article comprises first and second substrates and one or more elastic elements disposed at least partially intermediate the substrates. The second substrate is attached to the first substrate and/or to portions of the elastic elements. The absorbent article comprises an adhesive having a first and second pattern of elements disposed on first substrate, and first and second texture zones. The first texture zone comprises a first portion of the substrates, a first portion of the elastic elements, and the first pattern of elements of the adhesive and forms a background pattern in the first portion of the substrates. The second texture zone comprises a second portion of the substrates, a second portion of the one or more elastic elements, and the second pattern of elements of the adhesive and forms a macro pattern in the second portion of the substrates.
