Abstract

<p>In order to find the criteria for judging worn level among fabrics abraded by friction, their compression properties, surface properties, thickness, weight, color difference and impression evaluation were investigated for different abrasion degree in relation to their tensile property. <br>The change in the tensile strength of the abraded fabrics showed rather good correlation with the change rate in their compression property, surface properties, thickness and weight. The proportionality between the score of “faded” and that of “worn” has been found by the impression evaluation of fabric hand by comparison method, indicating the color fading is recognized as the fabric wearing. <br>When the properties obtained for the abraded fabrics was compared with the breaking strength to be cleared by merchandizing fabrics, shown in JIS, and the color changes of the abraded fabrics with the change of the impression evaluation score of “worn”, the change rate of -20～-28% in the resilience of compression, less than -2% in the thickness, -7～-16% in the weight, and the change of the color difference, ⊿E*ab, greater than 1.5, or “Noticeable” seem to be criteria of the worn level of fabrics.</p>
