Problems solved by technology

However, when many absorbent sheets are used, or the amount of water-absorbent resin powder per absorbent sheet is increased, the ratio of the water-absorbent resin powder contained in the entire absorbent pad increases, resulting in a hard absorbent pad, resulting in Hard wearing feeling
In addition, if the area of ​​each absorbent sheet is increased, the area of ​​the disposable absorbent article itself must be increased accordingly, which is inconvenient not only for manufacture but also for use.
[0010] In addition, since the main component of the above-mentioned absorbent sheet is the water-absorbent resin powder, which exhibits the absorption performance, it is inferior in water absorption speed when compared with a conventional absorbent pad mainly composed of pulp fibers.

Embodiment

[0094] [Example (example of the present invention)]

[0095] In Examples, absorbent articles were manufactured using the sheet-shaped water-absorbent layer of the present invention instead of the water-absorbent resin interspersed between the upper fiber aggregate and the surface sheet in Comparative Example.

[0096] The flake-shaped water-absorbing layer is coated with the above-mentioned hot-melt adhesive in a net shape on the inner surface of the first (front side) non-woven fabric and the second (back side) non-woven fabric (coating amount: both the front and back sides are 10g / m 2 ), made by attaching water-absorbent resin here.

[0097] As the first non-woven fabric, a so-called non-measurable non-woven fabric (area density non-woven fabric) in which fibers mixed in a mass ratio of rayon fibers and polyester fibers to about 7:3 were cut and hydroentangled was used. : 40g / m 2 ), as the second nonwoven fabric, a breathable nonwoven fabric (area density: 20g / m 2 ), tha...

Abstract

The invention provides a disposable absorbent article including an absorbent mat between a liquid-permeable top sheet and a liquid-impermeable back sheet. The absorbent mat includes a sheet-shaped water-absorbent layer that contains a water-absorbent resin powder but that does not contain pulp fibers; and a fiber assembly layer that contains a water-absorbent resin powder and pulp fibers in this order from a top sheet side. The sheet-shaped water-absorbent layer includes a plurality of water-absorbent resin presence regions in each of which the water-absorbent resin powder is wrapped; and a plurality of water-absorbent resin powder absence regions each being formed between the two adjacent water-absorbent resin powder presence regions.

Description

technical field [0001] The present invention relates to disposable absorbent articles such as disposable diapers and disposable underwear. Background technique [0002] In recent years, in the field of sanitary materials using disposable absorbent articles such as disposable diapers, disposable underwear, and menstrual napkins, especially in the field of adult disposable diapers required for excretion care of the elderly In order to make the wearer not have to be picked up many times by changing diapers, and in order to reduce the physical burden on the caregiver, it is desirable to have a form with high absorption that can withstand long-term use and is difficult to lose shape during use. Stable absorbent article. [0003] Absorbent articles used in the past are articles with an absorbent body between a liquid-permeable top sheet and a liquid-impermeable back sheet. Resin powder, thermoplastic fiber, etc. are made into a mat shape, and the absorbent pad is fixed by wrappi...
