发明名称 Absorbent article
摘要 An interior body of a disposable diaper includes a liquid-permeable front sheet, a liquid-impermeable back sheet and a liquid-retaining absorbent core. The front sheet has a single sheet including spunbond layers on the front side and back side and a melt blown layer between the spunbond layers. The absorbent core has fiber aggregates and super-absorbent polymer particles. The front sheet is directly bonded to the skin side surface of the absorbent core. The length of the front sheet is longer than the length of the absorbent core, so that the front sheet has extended sections which extend outward in the lengthwise direction from both ends of the absorbent core in the lengthwise direction, while the extended sections are each continuously connected in the transverse direction with the front sheet or back sheet which overlaps with the extended section. The extended sections can directly contact the skin of the wearer.

主权项 1. An absorbent article comprising a liquid-permeable front sheet, a liquid-impermeable back sheet and a liquid-retaining absorbent core, wherein the front sheet consists of a single laminated sheet comprising spunbond layers on front and back sides and at least one melt blown layer between the spunbond layers, wherein the spunbond layer on the front side has a pattern embossed surface, and the spunbond layer on the back side has a flat embossed surface, the absorbent core consists of fiber aggregates and super-absorbent polymer particles, the front sheet covers a skin side surface of the absorbent core while being directly bonded to the skin side surface, the length of the front sheet in a lengthwise direction of the absorbent article is longer than the length of the absorbent core in the lengthwise direction so that the front sheet is provided with extended sections which extend outward in the lengthwise direction from both ends in the lengthwise direction of the absorbent core, the extended sections being each continuously connected in a transverse direction of the absorbent article with the front sheet or back sheet which overlaps with the extended section, the extended sections are adapted to contact the skin of a wearer, the spunbond layer on the front side is directly contactable with the skin of the wearer, the spunbond layer on the back side is in direct contact with at least one of the fiber aggregates or super-absorbent polymer particles on the skin side surface of the absorbent core, and a fiber density of the spunbond layer on the back side is higher than that of the spunbond layer on the front side.
