Problems solved by technology

[0011] In this product 1C, although the film f7 can prevent the infiltration of bodily fluids to the 1st and the 2nd fiber non-woven fabrics f8, f9, because the film f7 is bonded and fixed to the sheet 22 and the 1st fiber non-woven fabric by the adhesive g, fabric f8, so the adhesive g hinders the moisture permeability of the film f7 and reduces the moisture permeability of the article 1C in the area where the sheet 22 is located
When the article 1C is worn, it is difficult for the moisture inside the article 1C to penetrate to the outside of the article 1C, so that the moisture and heat inside the article 1C cannot be prevented.

Abstract

A disposable wearing article 1A comprises a liquid-pervious topsheet 2, a liquid-impervious backsheet 3 and a liquid-absorbent panel 4 interposed between the top- and backsheets 2, 3. The backsheet 3 is formed by a breathable and hydrophobic first fibrous nonwoven fabric layer f2 underlying the panel 4, a breathable and liquid-impervious plastic film f4 underlying the first fibrous nonwoven fabric layer f2 and a breathable and hydrophobic second fibrous nonwoven fabric layer f3 underlying the film f4. In a zone occupied by the panel 4, the first fibrous nonwoven fabric layer f2 is intermittently joined to an under surface of the panel 4 by means of a hot melt adhesive and the film f4 is intermittently joined to the first fibrous nonwoven fabric layer f2 by means of the hot melt adhesive.

Description

Technical field [0001] The invention relates to a disposable wearing article for absorbing and retaining excrement. Background technique [0002] As a disposable wearing article of the known technology, a liquid-absorbent sheet is interposed between the liquid-permeable surface layer on the skin-contacting side and the liquid-impermeable inner layer on the non-skin-contacting side; and it has a front waist area and a back The waist area, and the crotch area located between the front and back waist areas; it also has a pair of end flaps located outside the two ends of the liquid-absorbent sheet, and a pair of side flaps located outside the two-side edges of the liquid-absorbent sheet. [0003] Refer to Figure 8 ~ Figure 10 An example of the aforementioned well-known wearing article will be described. Figure 8 In order to show a partially cut-away exploded plan view of the article 1C in a state where the front and rear waist regions 23 and 25 are disconnected. Picture 9 , 10 Res...
