Absorbent material and absorbent article using same

Abstract

To produce an absorbent body which is a combined absorbent body with tissue paper and an absorbent core resistant to separation between the tissue paper and the absorbent core, an with stiffness of the whole of the absorbent body not to become an inconvenient level by using an appropriate combining means, in the absorbent body enveloping the absorbent core mainly made from cotton-like pulp by the tissue papers. In the absorbent body of a square shape in which the absorbent core is mainly composed of the cotton pulp is enveloped by the tissue paper, a plurality of embossed parts of deep circular shape which are distributed at least in almost a whole of a central area of the absorbent body are created from above surface side tissue paper, and bottom parts of the embossed parts are closely integrated into surface side tissue paper, a consolidated core part and rear side tissue paper.

Description

technical field [0001] The present invention relates to an absorbent body used in absorbent articles, and more particularly to an absorbent body suitable for absorbent articles such as sanitary napkins and pads for mild incontinence, and an absorbent article using the absorbent body. Background technique [0002] As the absorber of absorbent articles, well known are absorbers in which cotton-like pulp as the main body is mixed with a superabsorbent resin for improving its absorbency as the case may be to make a liquid-absorbent core, and then wrapped with tissue paper Wrap it up. The basic form of this absorbent article is that a liquid-permeable outer layer and a liquid-impermeable inner layer wider than the absorbent body are arranged on the upper and lower sides of the absorbent body. These two layers are glued together on the outer side of the absorbent body. A leak-proof layer is provided on the peripheral edge. [0003] In this known absorbent body, tissue paper is u...

Problems solved by technology

Furthermore, the outer layer and the tissue paper become one and attached to the excretory part of the human body, so that there is a distance between the tissue paper and the liquid-absorbent core, so that the body fluid that reaches the outer layer cannot be smoothly transferred to the liquid-absorbent core, and it is easy to Problems such as side leakage along the outer layer

[0008] In addition, as described in Patent Document 1, when the concave embossed parts are formed by pressing from the outer layer to the absorbent body on the left and right sides of the absorbent article, the aforementioned tissue paper and absorbent parts will also appear in the area between the embossed parts. Liquid cores are as easy to peel off similar issues
