Problems solved by technology

[0006] It has been found that an absorbent core that is stretched and somewhat stretched, when incorporated into a disposable diaper that has been attached to the wearer, can give the backsheet a stretched appearance, resulting in the formation of, for example, tension lines or wrinkles
Such a taut appearance may cause concern for the wearer, or (if the wearer is an infant or toddler) the caregiver for general quality, especially the capacity of the disposable diaper

Embodiment Construction

[0023] definition

[0024] "Absorbent core" means a structure disposed between the topsheet and backsheet of a disposable diaper for absorbing and containing liquid received by the disposable diaper.

[0025] "Airfelt" as used herein refers to comminuted wood pulp in the form of cellulose fibers (absorbent fibers).

[0026] "Diaper" means an absorbent article generally worn by infants and incontinent persons around the lower torso so as to encircle the wearer's waist and legs and which is particularly adapted to receive and contain urine and feces. For the purposes of the present invention, the term "diaper" is considered to cover "diaper pants".

[0027] The term "diaper pants" as used herein refers to disposable garments designed for infant or adult wearers having a waist opening and leg openings. The diaper pants are donned to the user by inserting the wearer's legs into the leg openings and pulling the pants into position about the wearer's lower torso. The diaper pan...

Abstract

The invention relates to disposable diaper having absorbent cores comprising superabsorbent polymer particles which are immobilized by adhesive. The absorbent core is attached to the backsheet of the disposable diaper only in certain attachment zones to reduce see-through and the formation of tension lines on the backsheet.

Description

technical field [0001] The present invention relates to disposable diapers having an absorbent core comprising superabsorbent polymer particles held in place by an adhesive. The absorbent core is attached to the backsheet of the disposable diaper only in certain attachment areas to reduce see-through and tension line formation on the backsheet. Background technique [0002] The use of superabsorbent polymer materials in disposable diapers is well known. Compared to the use of absorbent materials such as fluff pulp, the use of superabsorbent polymer materials is advantageous for disposable diapers with thinner absorbent cores, especially when the disposable diapers are in the dry state. [0003] Today, most commercially available disposable diapers still have an absorbent core comprising a mixture of so-called airfelt (cellulose fibers) and superabsorbent polymer particles. The cellulose fibers included in the absorbent core generally hold the superabsorbent polymer particl...
