PROBLEM TO BE SOLVED: To provide a comfort evaluation method of wearing article capable of objectively evaluating the comfort of a wearing article by associating measured values based on near-infrared spectroscopy (NIRS) and physical properties of the wearing article.SOLUTION: The comfort evaluation method comprises the steps of: acquiring a time-base waveform data of a frictional resistance force which is generated in a second direction opposite to a first direction when gently passing a hand along the first direction over the surface of a wearing article which comes into contact with a skin carrying out a Fourier transform on the acquired waveform data calculating the ratio of the sum of first predetermined number of amplitude peaks of a frequency spectrum obtained by carrying out the Fourier transform and the sum of second predetermined number of amplitude peaks, the second predetermined number being smaller than the first predetermined number, with respect to the sum of the first predetermined number of amplitude peaks and evaluating the comfort of the wearing article based on an association among the sum of the first predetermined number of amplitude peaks, the sum of the second predetermined number of amplitude peaks and a measured value of brain function by means of near-infrared spectroscopy.COPYRIGHT: (C)2015,JPO&INPIT【課題】近赤外線分光法(NIRS)に基づく測定値と、着用物品の物性とを対応付けることによって、着用物品の快適性を客観的に評価し得る着用物品の快適性評価方法を提供する。【解決手段】本発明に係る快適性評価方法は、着用物品の肌当接面の表面を第1方向に沿って撫でることによって、第1方向と正反対の第2方向に発生する摩擦抵抗力の時間軸における波形データを取得するステップと、取得した波形データに対してフーリエ変換を実行するステップと、フーリエ変換の実行によって得られた周波数スペクトルの第1所定数の振幅ピークの和、及び第1所定数よりも少ない第2所定数の振幅ピークの和の第1所定数の振幅ピークの和に対する割合とを算出するステップと、第1所定数の振幅ピークの和及び第2所定数の振幅ピークの和と、近赤外線分光法による脳機能の測定値との対応付けに基づいて、着用物品の快適性を評価するステップとを備える。【選択図】図2
