摘　　要：针对广西部分生丝产品品质等级一般,且利润低的问题,文章依据国家标准对某企业生产的55批鲜茧生丝样品进行检验,借助过程能力指数法分析了该企业的缫丝过程能力并指出需要改进的方向,以期达到提高产品质量和降低生产成本的目的。结果表明,该企业生产过程的纤度偏差、清洁、洁净、纤度最大偏差的过程能力指数分别为1.53、0.71、2.75、0.99,说明企业的纤度偏差过程能力良好;清洁和纤度最大偏差的过程能力较差,需要持续改进;洁净过程能力为特优,可考虑降低生产成本。The quality grade of Guangxi raw silk is not high and the profit is low. For these problems,55 batches of fresh cocoon raw silk from an enterprise were tested according to the national standards in this paper,and then process capability index method was used to analyze the ability of reeling process capability,and the direction of improvement was pointed out,in order to further improve product quality and reduce production cost. The results showed that the process capability indexes of size deviation,cleanness,neatness and the maximum size deviation were 1. 53,0. 71,2. 75 and 0. 99 respectively in this enterprise. This means that the process capability of size deviation is good; the process capability of cleanness and the maximum size deviation is poor, which needs continuous improvement; the process capability of neatness is excellent,and the reduction of production cost may be considered.
