Analysis of aurora forming in wearing and tentative solution exploration in wool uniform fabric

In order to solve the problem of the formation of the aurora in dressing,and then improve the practical value of clothing,the paper analysed the causes and solutions of the wool uniform fabrics′auroral phenomena.Through the analysis of the fabrics′ fiber composition of the aurora and no aurora,and the analysis of thickness,structure and SEM,the main reason of the phenomenon that produced fabric aurora is thought to be 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,and the strengthening light reflection caused the aurora.Through the washing,pickling,alkali wash(dilute ammonia) of aurora fabric,lemon,and acetic acid are thought to be good materials used to eliminate the aurora,dilute ammonia although can eliminate the aurora,but alkaline substances will damage the wool fiber,so dilute ammonia is avoided to be used.
