Problems solved by technology

Since the pill-shaped portion tends to retain liquid, the liquid may remain near the surface of the top sheet, which may deteriorate the appearance after absorbing liquid, or cause stickiness, etc.
In addition, liquid absorption is also poor due to the presence of cavities with a certain height between the single fiber layer and the underlying substrate layer

Embodiment Construction

[0036] Hereinafter, the present invention will be described based on preferred embodiments of the present invention with reference to the accompanying drawings.

[0037] Fig. 1 is a perspective view showing one embodiment of the topsheet for absorbent articles of the present invention.

[0038] The topsheet 10 shown in FIG. 1 is used for the skin-contacting surface of absorbent articles such as disposable diapers, sanitary napkins, panty liners (panty liners), and incontinence pads.

[0039] The surface sheet 10 is comprised from the 1st nonwoven fabric 1 and the 2nd nonwoven fabric 2 laminated|stacked mutually. The first nonwoven fabric 1 forms the surface of the topsheet 10 facing the wearer's skin (skin contacting surface), and the second nonwoven fabric 2 forms the surface of the topsheet 10 facing the absorber side (non-skin contacting surface).

[0040] The first nonwoven fabric 1 and the second nonwoven fabric 2 are thermally fused locally, whereby many thermally fused...

Abstract

A face sheeting is used as a skin contact surface for an absorbency object, and stacked first non-woven fabrics and second non-woven fabrics are partially melted and cohered to form a melted cohere part. Other parts of the first non-woven fabrics except the melted cohere part protrudes to the skin of the wearer to form a plurality of bulges. The bulge and the melted cohere part are disposed alternately to form an array arrangement with a plurality of arrays. At least part of bulges in a fiber orientation direction of the first non-woven fabrics have a fiber sparse part with a lower fibre density than that at a center part in the fiber orientation direction at one end or two ends.

Description

technical field [0001] The present invention relates to a front sheet (laminated nonwoven fabric) suitable for the skin-contacting surface of absorbent articles such as disposable diapers, sanitary napkins, panty liners (sanitary pads), and incontinence pads, and its manufacture method. Background technique [0002] As top sheets of disposable diapers, sanitary napkins, etc., sheets having unevenness formed on the surface that contacts the wearer's skin are widely used. The front sheet with unevenness can reduce the sticky feeling and air tightness due to the existence of the unevenness can reduce the contact area with the wearer's skin. [0003] As a surface sheet having concavities and convexities, for example, it is known to integrate a thick sheet material with another sheet material by embossing so that the compressed portion formed by embossing becomes a concave portion and the other portion becomes a convex portion. Sheet. [0004] In addition, Patent Document 1 de...
