摘要:
To provide an article in which a hot melt adhesive is used to affix elastically stretchable members and to adhere a first sheet layer and a second sheet layer, the article maintaining both flexibility and the fixation of the elastically stretchable members. The aforementioned problem is resolved by providing a first sheet layer (12S) comprising a nonwoven fabric, a second sheet layer (12H) facing one surface of the first sheet layer (12S) and comprising a nonwoven fabric, and, between the two sheet layers, a plurality of slender, elongate elastically stretchable members (19) provided extending in the stretch direction with spaces therebetween. At least a part of both ends of the elastically stretchable members (19) are affixed to at least one among the first sheet layer (12S) and the second sheet layer (12H) by only a first hot melt adhesive (71). The first sheet layer (12S) and the second sheet layer (12H) are bonded by a second hot melt adhesive (72) in a stretch direction range corresponding to the space between both ends of the elastically stretchable members (19). The holding power of the first hot melt adhesive (71) is greater than the holding power of the second hot melt adhesive (72).本發明所欲解決的問題在於:針對藉由熱熔黏合劑來實行彈性伸縮構件的固定、及第一片層和第二片層的接合所構成的物品,謀求可兼具柔軟性和彈性伸縮構件的固定性。   作為解決上述問題的手段,可藉由下述吸收性物品的伸縮結構來解決,該吸收性物品的伸縮結構具備:第一片層12S,其由不織布所構成;第二片層12H,其相對向於該第一片層12S的其中一面且由不織布所構成;及,複數根細長狀的彈性伸縮構件19,其在該第一片層12S和第二片層12H之間,沿著伸縮方向且互相隔開間隔地設置;其中,彈性伸縮構件19的兩端部的至少一部分,僅藉由第一熱熔黏合劑71而被固定在第一片層12S和第二片層12H中的至少其中一方;在與彈性伸縮構件19的兩端部之間對應的伸縮方向範圍內,第一片層12S和第二片層12H,藉由第二熱熔黏合劑72而被黏合在一起;第一熱熔黏合劑71的保持力高於前述第二熱熔黏合劑72的保持力。
