摘要:
A stretchable laminated sheet with hydrophilic properties, which particularly has an excellent feeling and stability in wearing and is capable of efficiently enhancing the effect and efficacy brought about by a liquid component on a skin or other object, when the stretchable laminated sheet is impregnated with the liquid component and wet and then used on the skin or other object. A stretchable laminated sheet, which is obtained by partially thermocompression-bonding and laminating a hydrophilic short fiber layer extensible in at least one direction and an microfiber layer having a elastomer long fiber of a fiber diameter of 15 µm or less at 50% or more by weight, wherein discontinuous and regular concave and convex parts caused by the partial thermocompression bonding are formed on a surface of the hydrophilic short fiber layer that is exposed on one surface of the stretchable laminated sheet, the total area of the concave parts is in a range of 3 to 40% of the area of the surface of the hydrophilic short fiber layer, and at least the elastomer long fiber of the microfiber layer is softened and consequently joined to a fiber constituting the hydrophilic short fiber layer in a sheet thickness direction of a section where the concave parts exist, whereby the hydrophilic short fiber layer and the microfiber layer are integrated with each other.本發明的伸縮性積層片材是利用部分熱壓接,將至少一方向具有延長性的親水性短纖維層與極細纖維層進行積層而成的,所述極細纖維層以重量基準表示為50%以上的範圍包含纖維徑為15μm以下的彈性體長纖維;並且在露出於該片材的一面的親水性短纖維層表面形成由所述部分熱壓接所引起的不連續且規則的凹凸形狀,凹部總面積在親水性短纖維層的該表面上占3~40%的範圍,在該凹部所在部位的片材厚度方向,至少極細纖維層中的彈性體長纖維由於其軟化而與構成親水性短纖維層的纖維接合,由此使親水性短纖維層與極細纖維層成為一體。
