Study on the Quality Appraisement of Sports Wear -Establishment of Appraisement Method to Deterioration of Polyurethane Processing Materials-
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.13 Vol.13】
The problems on durability performance evaluation of polyurethane processing materials used widely in sports wear are delaminating, crack and cleaning trouble in the practical useing period.
The purpose of this study, therefore, is to performance evaluation of polyurethane processing materials whether polyurethane textile materials will or will not deteriorate under normal storage conditions and to establish the degree of such deterioration before the happening of an accident.
The experimental design are to determine the safe condition toward the delaminating test and crumple test on samples of laboratory made and of commercial use, surface structure changes, decomposition behaviors of polyurethane and strength of tested fabrics by means of the studies of jungle test and fastness to light.
From the results, we have concluded that following method would be most suitable for assessing the appraisement or detection of samples : the accelerated appraisement test method before the happening of an accident are jungle test (ageing at 70°C, > 95% RH) or jungle test used artificial perspiration solution : the detection method of the polyurethane processing materials are fastness to crumple test.
