In this paper,the authors discuss the problem of gradual sneaker yellowing with time going on,a-dopting the methods of induction and theoretical analysis. Taking the effects of the shoe's material as well as the detergent and water into account,the authors analyze the reasons why sneaker turns yellow from an angle of yellowing mechanism and influencing factors. Besides,in this paper,the methods of avoiding sneaker yellowing shall be elaborated and a new type of membrane patchtargeting atsneaker yellowing shoes shall be put for-ward. The results show that the ultraviolet and oxygen exert influences on the materials and the detergent to var-ying degrees.%针对运动鞋随时间逐渐发生黄变问题,采取归纳与理论分析的方法,从黄变机理和影响因素角度,考虑鞋子本身材料以及洗涤剂和水的影响分析了运动鞋黄变原因,并阐述了避免黄变的途径,提出了针对运动鞋黄变的新型膜贴.研究结果表明,紫外线和氧气等对材料以及洗涤剂都有不同程度的影响.
