Absorbency substance and manufacturing method thereof

Abstract

The invention provides an absorbable article and a method for manufacturing the same, which has strong felling of stereo perception, high shock-absorbing capacity, capable of minimizing area contacting with skin, and can maintain concavo convex embossing shape all the time. A surface sheet (3) is a multilayer sheet having two layer which comprises at least a non-woven favrics layer (3A) constituting skin contacting layer and a plastic film layer (3B) stacking on a non-skin contacting layer side of the non-woven favrics layer (3A), and the plastic film layer (3B) is formed by materials having the melting point lower than the non-woven favrics layer. Concavo convex shape embossing and a plurality of tapping treatments are implemented on a compounding sheet comprising the surface sheet (3) and a second non-woven favrics sheet (6) formed by materials having the melting point lower than the non-woven favrics layer (3A) which is bonding to the inner side fo the surface sheet (3), in a heating condition not less than the melting point of the plastic film layer (3B) and the non-woven favrics sheet (6), and less than the melting point of the non-woven favrics layer (3A).

Description

technical field [0001] The present invention relates to an absorbent article using a surface sheet that is rich in three-dimensionality and has high cushioning properties and eliminates skin troubles by reducing the contact area with the skin, and a method for manufacturing the same, and the surface sheet is embossed in a concave-convex shape Excellent shape retention. Background technique [0002] Conventionally, as surface materials of absorbent articles, materials with appropriate embossed patterns for the various purposes of reducing the contact area with the skin to suppress wetness, or obtaining texture and improving tactile sensation have been provided on the market. Examples of such materials include the techniques of the following Patent Documents 1 to 5 and the like. [0003] Patent Document 1 below discloses an absorbent article using, as a top sheet, a nonwoven fabric having a plurality of openings, on which a plurality of ridges and grooves are alternately arra...

In addition, although the fiber part of the raised part can ensure the raised amount in a dry state, when it becomes a wet state, the fiber is naturally compressed (sluggish state), the raised amount is reduced, and the cushioning performance is extremely reduced, and the shape retention of unevenness is insufficient.
