Absorbency substance

Abstract

The present invention provides an absorbability article which has cubic effect, high buffering property, and can keep concave-convex form not only under drying condition but also under the condition of absorbing sap by improving the form retentivity of concave-convex embossed pattern. The absorbability article (1) is provided with an absorbing body (4) between permeating front side and back side thin sheets (3) and (2), wherein, the front side thin sheet (3) is a multi-layer sheet which at least comprises a nonwoven cloth layer (3A) forming the skin contacting surface and a plastic film layer(3B) laminated on the non skin contacting surface of the nonwoven cloth layer, the plastic film layer (3B) is composed of material with a melting point lower than the nonwoven cloth. Under the heating condition with a melting point higher than the melting point of the plastic film layer (3B) and lower than the melting point of the nonwoven cloth layer (3A), the concave-convex embossing process composed of a plurality of projecting parts (7, 7......) projecting outside is executed to the front side thin sheet (3), and the hole making process is executed to the top of the convex embossed pattern or the bottom of the concave embossed pattern of the concave-convex embossed pattern.

Description

technical field [0001] The present invention relates to an absorbent article having a front sheet, which is rich in three-dimensionality and has high cushioning properties, eliminates skin problems by reducing the contact area with the skin, and has excellent shape retention of uneven embossing. Background technique [0002] Conventionally, as the surface material of absorbent articles, there are products in which appropriate embossing patterns are applied for the purpose of suppressing wetness by reducing the contact area with the skin, obtaining texture, and improving tactility at the same time. As such a product, the following patent documents 1-5 are mentioned, for example. [0003] Patent Document 1 below discloses an absorbent article using a nonwoven fabric as a front sheet, on which a plurality of raised portions and grooves are alternately arranged without a planar portion, and the raised portions The groove portion is convexly curved and concavely curved, and the ...

AI Technical Summary

Problems solved by technology

[0013] For the front sheet described in the above-mentioned Patent Document 1, it is true that a three-dimensional effect is created on the surface of the sheet by alternately arranging the ridges and grooves, but the ridges are in linear contact with the skin and have a large contact area with the skin, which cannot effectively prevent chafing. Injury, inflammation, itching and other skin problems, and can not eliminate the feeling of stiffness when bleeding

In addition, the shape retention of the wave processing that forms the protrusions and grooves on the nonwoven fabric is not sufficient, and there is a problem that the degree of unevenness of the wave processing gradually decreases when the state of being subjected to pressure during sitting or sleeping continues.

In addition, the fiber part of the raised part can ensure the raised amount in the dry state, but when it becomes wet, the fiber naturally compresses (shrinks), the raised amount decreases, and there is a problem that the shape retention of the unevenness is insufficient, such as the cushioning property is extremely reduced.
