Abstract: In order to solve the problem of the formation of the aurora in dressing, then improve the practical value of clothing. The paper analysed the causes and solutions of the wool uniform fabrics’auroral phenomena. Through analyse the fabrics’fiber composition of the aurora and no aurora, and the analysis of thickness ,structure and SEM.We think the main reason of the phenomenon that produced fabric Aurora is friction, tensile, compression and other external force, the fabric structure phase change caused the fabric to become flat, the tribute of the top satin weave substructure is flattened, wool scales injury and dust between yarns and even within the yarn, which induce the fabric surface becomes smooth, the strengthening light reflection caused the aurora; Through the washing, pickling, alkali wash ( dilute ammonia ) of aurora fabric, From these: lemon, acetic acid are good materials used to eliminate the aurora , but acetic acid should be moderate, dilute ammonia although can eliminate the aurora, but alkaline substances will damage the wool fiber, so we should not use dilute ammonia as we can.

Key words: wool fabric, auroral phenomena, analysis of cause, solution
