Study on the Quality Appraisement of Sports Wear* -Colour Change to Active Chlorine in Service and Pool Water-
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.4 Vol.4】
The test method for colour fastness of textiles to chlorinated water (JIS L 0884-1977) authorized now has been recognized to be not necessarily suitable for quality appraisement of sports wear.
Recently, it has been pointed out that even if the textiles passed in this test often appriciably changed in colour in practical end-uses.
In this study, the new test method for colour fastness of sports wear to chlorinated water more suitable for quality appraisement of textiles was investigated by studying the relations between the observation of the colour change and various testing conditions: oxidation potential of chlorinated water, concentration of active chlorine, temperature, pH, stability and practical end-uses.
For the results, it can be concluded that following method used apparatus for testing of colour fastness to washing would be most suitable for assessing the colour fastness to chlorinated water in practical end-uses:
