Disclosed is a water-absorbable sheet structure in which a water-absorbing layer comprising water-absorbable resins (A) and (B) is sandwiched between fibrous webs from the top surface side and the lower surface side of the water-absorbing layer, wherein the water-absorbable sheet structure is characterized in that the total content of the water-absorbable resins (A) and (B) is 100 to 1000 g/m 2 , and the water-absorbable resins (A) and (B) have the following properties: (1) the water-absorbable resin (A) has a physiological saline retention (Ra) of 15 to 55 g/g; (2) the water-absorbable resin (B) has a physiological saline retention (Rb) of 10 to 50 g/g; and (3) the aforementioned Ra and Rb meet the relationship represented by the formula Ra-Rb ≥ 5 (g/g). The water-absorbable sheet structure can have good shape retention properties even when the water-absorbable sheet structure is thin, and therefore has such excellent effects that the water-absorbable sheet structure can keep the shape thereof well before and after the absorption of a liquid and can exhibit absorption performance satisfactorily.

Absorbent article having improved absorption properties

An absorbent article such as disposable diaper, training pant, and adult incontinence undergarment comprising superabsorbent polymer particles able to absorb and contain body exudates having improved absorption properties and therefore reduce leakage, especially at the first gush, i.e. when the article starts to be wetted.

Pad-shaped absorbent article

Provided is a pad-shaped absorbent article that contains highly water-absorbent polymer particles. The pad-shaped absorbent article (1) is formed by interposing highly water-absorbent polymer particles (4) between opposing surfaces of two superposed sheets (2, 3).

This invention is directed to super-absorbent material, which comprises a super absorbent polymer core that is coated with an organic, polar coating agent, and whereby the particulate super-absorbent material has a contact angle and a corresponding cos CA m (as defined herein), whereby the cos CA m is more than 0.3, and whereby, when said coating agent is in the form of particles, said coating agent particles have a (weight) mean particle size of from 0.001 to 1 micron. The material is useful for absorbent structures and absorbent articles (comprising such structures). The coated super-absorbent material is typically present in said absorbent structure at least at a concentration of 50% by weight of the structure, preferably even 80% or even 90%. The invention also provides a process for making the absorbent material.

Absorbent cores for absorbent articles and method for making same

An absorbent article is provided, including a barrier layer, a cover layer extending substantially parallel to the barrier layer, and a superabsorbent polymer interposed between the cover layer and the barrier layer. The superabsorbent polymer is adhered to the article in a pattern configured to distribute fluid in the absorbent article, wherein at least one portion extending essentially completely across the absorbent article is substantially devoid of the superabsorbent polymer.

Drapeable sanitary absorbent napkin

An absorbent article including a cover layer, a barrier layer and an absorbent system arranged between the cover layer and the barrier layer, the absorbent article being drapeable and possessing the absorbency attributes required of a sanitary napkin.

Method of making an absorbent composite and absorbent articles employing the same

A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.

Drapeable absorbent article

An absorbent article including a cover layer, a barrier layer and an absorbent system arranged between the cover layer and the barrier layer, the absorbent article being drapeable and possessing the absorbency attributes required of a sanitary napkin.

Better Fitting Disposable Absorbent Article With Absorbent Particulate Polymer Material

A disposable absorbent article includes an absorbent core that is substantially cellulose free and a chassis that includes a topsheet and a backsheet, with the absorbent core located between the topsheet and the backsheet. The chassis may include a pair of side panels joined with the chassis, the side panels extending laterally outwardly beyond the longitudinal edges, each side panel having at least one zone extensible in a direction having a vector component in the lateral direction.

Absorbent core

Absorbent core for disposable absorbent articles, for example for the absorption of menses or blood. The absorbent core comprises a substrate layer, thereon a layer of absorbent polymer material, and thereon a layer of adhesive. Either said a substrate layer or said cover layer or both may comprises o composite of at least a first layer and third layer of fibrous non-woven webs, said first layer and said third layer comprising synthetic fibers with an average fiber denier from 1 to 6, said composite further comprises a second layer comprising pulp; the layers of the composite being placed in the order first- second- third and bonded by intertwining the fibers between the layers, e.g. by hydroentanglement. Said first and third layers of said composite may be spunbonded.
