PROBLEM TO BE SOLVED: To provide a nonwoven fabric having stretching characteristics and standing repeated use, since there is a problem that the use of the non-woven fabric which is more preferable as a stretchable member in view of air-ventilation property and touch feeling to films, as disposable hygienic materials, such as diaper or the substrate of a pasting material, is increasing, and as the material used for the stretchable member, the non-woven fabric consisting of only with an elastomer having rubber elasticity is cited, however, in use in contact with a skin, the touch feeling is rubber like and it is not suitable in view of the touch feeling or the like.SOLUTION: This stretchable non-woven fabric has partial fiber-gathering regions at a high density, separated from partial thermally compressed parts, on at least a surface layer of a stretched nonwoven fabric, and having a surface area rate of the fiber-gathering region at the high density of 5-70%.COPYRIGHT: (C)2008,JPO&INPIT【課題】 オムツ等の使い捨て衛生材料や,貼布材の基布に,通気性,風合の面から伸縮部材としてフィルムよりも好ましい不織布の使用が多くなってきている。それら伸縮部材に用いられる材料として,ゴム弾性のあるエラストマーのみからなる不織布が上げられるが,肌に接触する用途においては触感がゴム様であり風合の面で適さないなどの問題があった。そこで繰返し使用に耐える伸縮特性を有した不織布を提供する。【解決手段】延伸処理した不織布の少なくとも表面層に、部分熱圧着とは別である部分的な繊維高密集域を有し、該繊維高密集域の面積率が5~70%である伸縮性不織布。【選択図】図3
