PROBLEM TO BE SOLVED: To provide a stretchable nonwoven fabric without exuding a plaster to the surface on the side opposite to the coated surface even when the thickness is reduced and to provide a method for producing the stretchable nonwoven fabric.SOLUTION: The stretchable nonwoven fabric is obtained by entanglement of mutual constituent fibers of a fiber web including crimped fibers as a main component. Furthermore, in the stretchable nonwoven fabric, crimped fibers are subjected to water-repellent treatment with a water-repellent treating liquid containing a water-repellent treating agent using a beam dyeing machine after developing the crimps of the latently crimpable fibers. The method for producing the stretchable nonwoven fabric includes a step of carrying out an entanglement of a fiber web including the latently crimpable fibers as a main component, then heat shrinking the latently crimpable fibers at a crimp developing temperature and forming a stretchable fiber web and a step of performing the water-repellent treatment of the stretchable fiber web with the water-repellent treating liquid containing the water-repellent treating agent using the beam dyeing machine.COPYRIGHT: (C)2009,JPO&INPIT【課題】 厚さが薄くなっても、膏体が伸縮性不織布の塗布面とは反対側の面に染み出してしまうことのない伸縮性不織布及びその製造方法を提供する。【解決手段】 捲縮繊維を主体とする繊維ウエブの構成繊維同士が交絡してなる伸縮性不織布であって、前記捲縮繊維は潜在捲縮性繊維の捲縮が発現した後に、撥水処理剤を含む撥水処理液を用いてビーム染色機によって撥水加工が施されている伸縮性不織布。潜在捲縮性繊維を主体とする繊維ウエブに交絡処理を施した後、前記潜在捲縮性繊維を捲縮発現温度で熱収縮せしめて伸縮性繊維ウエブを形成する工程と、撥水処理剤を含む撥水処理液を用いて、ビーム染色機によって前記伸縮性繊維ウエブを撥水加工する工程とを含む伸縮性不織布の製造方法。【選択図】 なし
