摘要
目前纺织品色牢度评级员目光评级一致性检验缺少直观量化的数理统计方法,因此提出Kappa系数在色牢度目光评级一致性评价中的应用思路。以针织学生服样品耐光色牢度为研究对象,设计3种样品方案,选择3名评级人员进行目光评级试验,并采用Minitab17软件分析评级员的Kappa值,重点研究样品设计中耐光色牢度低于4.0级的样品占比对Kappa值的影响。结果表明:样品方案中学生服耐光色牢度在3.0~4.0级的样品占比多时,方案越难,评级员的Kappa系数越小;Kappa系数一致性检验可直观量化评级员的重现性、再现性、准确性等指标,有利于管控评级风险。
Presently, there is lacking an intuitive and quantifiable statistical method for the consistency test among the color fastness rater’s visual. The idea of applying kappa coefficient is proposed. The light fastness of student clothing samples is taken as the research object, and the data is analyzed with minitab 17, and the focus is on the sample design, and it also studies the influence of the composition ratio of samples with light fastness grade less than 4 on the Kappa values. It shows that when the sample solution has a large proportion of samples with light fastness grade 3.0~4.0, the more difficult the solution is, the smaller the kappa coefficient of the rater is. The Kappa coefficient consistency test can intuitively quantify the reproducibility, accuracy and other indicators of the rating staff, which is conducive to the control of rating risks.
