摘要
黄度是影响纺织品外观及内在质量的一项重要质量指标。为使黄度和黄变评价在纺织上更好地发挥作用,系统地阐述了纺织品黄度、黄变以及黄度评价和黄变评价的相关标准与方法。将黄度评价方法分4类,将黄变评价方法分2类,分别进行详细介绍,并对黄度和黄变测评方法进行了对比。此外,对棉花颜色特征指标Rd、+b进行了分析,指出将Rd翻译或理解为反射率不恰当,Rd等于三刺激值之一的Y,应为明度或明暗度。目前,对纺织品黄度和黄变评价的研究还比较欠缺,需要深入,同时应加强对纺织品黄度和黄变测试标准的研制。
Yellowness is an critical quality index that affects the appearance and inner quality of textiles.In order to better utilize the evaluation of yellowness and yellowing in textiles,this paper systematically elaborates on the relevant standards and methods for textile yellowness,yellowing and their evaluation.The yellowness evaluation methods are classified into 4 categories,and the yellowing evaluation methods are divided into 2 categories,we provided a detailed introduction to each category and compared the yellowness and yellowing evaluation methods.In addition,an analysis was conducted on the color characteristic indicators Rd and +b of cotton.pointing out that translating or understanding Rd as reflectance is inappropriate,Rd is equal to one of the three stimulus values of Y,corresponding to brightness.At present,there is still a lack of research on the evaluation of yellowness and yellowing of textiles and it is necessary to deepen.Meanwhile,the test methods and standards for textile yellowness and yellowing should be developed and strengthened intensively.
