摘　　要：纱线条干均匀度是评估纱线质量和质地的重要指标,对纺织品质量、性能以及加工工艺有着重要影响,因此准确快速地测定条干均匀度在纺织工业中具有重要意义。通过回顾国内外相关文献,综合讨论了电容式、光电式和图像处理3种条干均匀度检测技术,并对各自的研究进展进行了详细阐述。重点讨论了条干均匀度检测技术的准确度、评价指标和技术要领等,分析了影响条干均匀度检测技术发展的相关因素,并从理论依据、研究方法和应用评价等角度讨论了条干均匀度检测技术目前存在的问题,为纺织工业中的条干均匀度检测提供一定参考,从而促进纺织行业的工业生产和技术进步。The evenness of yarn is an important parameter for evaluating the quality and texture of yarn.Therefore,the accurate and rapid measurement of yarn evenness occupies a very important position in the entire textile industry.Currently,there are three main techniques used for measuring yarn evenness:capacitive detection,optical detection,and image processing detection.This article describes the basic characteristics of yarn,introduces the evaluation indicators for measuring yarn evenness,and provides a comprehensive overview of the design principles and basic structures of these three different techniques for measuring yarn evenness.Additionally,the article summarizes the research directions of each technique,presents and analyzes the research achievements of these three techniques in different areas,and summarizes their advantages,limitations,and applicable scenarios.Furthermore,considering the current development of yarn evenness measurement techniques,the article explores the future prospects and directions for the development of these three techniques.The progress of the textile industry is driving the upgrade and iteration of yarn evenness detection technology.Traditional methods for evenness detection are no longer able to meet the high-precision and high-speed requirements in industrial applications.Among the three main technologies,capacitive detection is the most widely used and applied in mainstream evenness detection instruments.Capacitive detection primarily utilizes air capacitance as a sensing component to obtain the evenness index of the yarn relatively easily.However,this method can introduce errors due to variations in moisture content and blending ratio of the yarn.With the advancement of high-precision optical sensors,optical detection has gained wider application.Optical detection involves projecting a light beam onto the surface of the yarn and using optical sensors to collect corresponding data for analysis,thereby obtaining the evenness of the yarn.This method is susceptible to errors caused by
