Abstract: KES tester,LFY-1 crease recovery tester and YG811 drapemeter are employed to gain fabric basic mechanical property indexes,drape coefficient and crease recovery angle.In the experiment,the data of appearance retention of leisure trousers are obtained through subjective assessment.Then,the fabric basic mechanical property indexes characterizing the leisure trousers appearance retention are gained through applying grey system theory.On the basis,according to subjective data of appearance retention of leisure trousers,fuzzy comprehensive evaluation and approximate grey element model are used to evaluate the appearance retention of the leisure trousers.The results indicate that the two models are effective and certificating each other.
