PROBLEM TO BE SOLVED: To provide a nonwoven fabric for a heating implement which has soft texture and excellent flexibility, and to provide a heating implement using the fabric.SOLUTION: The nonwoven fabric for the heating implement is a composite nonwoven fabric obtained by laminating a first nonwoven fabric layer, which includes long-fiber having a basis weight of 8g/m2 to 25g/m2 and an average fiber diameter of 7 &mum to 30 &mum, on a second nonwoven fabric layer, which includes short-fiber having a basis weight of 20g/m2 to 50g/m2 and an average fiber diameter of 7 &mum to 30 &mum. Longitudinal bending rigidity in KES-FB2 is 0.035gf*cm/cm2 to 0.050gf*cm/cm2, and a compression characteristic in KES-FB3 is 0.55gf*cm/cm2 to 0.70gf*cm/cm2.COPYRIGHT: (C)2010,JPO&INPIT【課題】本発明は、ソフトな肌触り、柔軟性に優れている温熱具用不織布及びそれを用いた温熱具を提供する。【解決手段】本発明の温熱具用不織布は、目付が8g/m2~25g/m2であって、平均繊維径が7μm~30μmである長繊維を含む第一不織布層と、目付が20g/m2~50g/m2であって、平均繊維径が7μm~30μmである短繊維を含む第二不織布層とを積層してなる複合不織布であって、KES-FB2における縦方向の曲げ剛性が0.035gf・cm/cm2~0.050gf・cm/cm2であって、KES-FB3における圧縮特性が0.55gf・cm/cm2~0.70gf・cm/cm2であることを特徴とする。【選択図】図3
