Abstract: It has important practical significance for textile enterprises to evaluate objectively the yarn quality. Accor-ding to the disadvantage the existing evaluation system is overly dependent on subjective experience to determine,this paper put rough set theory into the evaluation of yarn quality,and put forward the discrete algorithm of the evaluation index and constructed the evaluation metric function.On this basis,the yarn quality evaluation model was established based on rough set.The experimental results show that the model is simple and high efficient,and provides more objective data for the quality manager to carry on the decision-making.
