The test method for colour fastness of textiles to compound action for perspiration and sunlight (JIS L 0888 '77) authorized now has been recognized to be not necessarily suitable for quality appraisement of sports wear.
　In this study, the ATTS new test method used acidic artificial perspiration test solution contained weekly reduction reagents (Vitamin, Glucose) to compound action for perspiration and sunlight more suitable for quality appraisement of sports wear was investigated by studying the relations between the wearing condition on sports and various testing condition.
