摘　　要：为了提高纱线和纺织品质量,以纤维素粘胶纤维与合成纤维涤纶为例,采用示踪纤维法对相应的生条、头并条、末并条内的纤维弯钩进行测试,并综合对比分析。首先制作荧光纤维,并将荧光纤维与原料混合后制条,然后对弯钩纤维的各种具体形态进行定义,观测条子内各种纤维的状态,并根据所给出的弯钩纤维的定义得到各种状态的弯钩纤维占比。本实验通过对各种形态弯钩纤维的细致定义,得到各种形态纤维的占比情况,为以后定量分析弯钩纤维提供了原始数据,另外通过对实验结果和原理的分析,也间接验证了此方法的有效性和准确性。Objective In order to improve the quality of yarn and textiles,this study tests and characterizes the fiber hook in chemical fier slivers,which is one of the most important internal performance indicators of fiber slivers,in order to explore the benefits to yarn producers in setting up production processes and optimizing spinning production parameters.Method In this study,the cellulose fiber and polyester fiber were selected to be the research objects,and the tracer fiber method was used to evaluate the fiber hooks in the corresponding raw fiber slivers,head slivers,and end slivers.Firstly,the fluorescent fiber was made and mixed with the raw material for making the raw slivers.The specific forms of the hook fibers were defined,the state of various fibers in the sliver was observed,and the proportion of the hook fiber in each state was obtained according to the hook fiber definition.Results In this study,the real state of fluorescent fibers in the viscose and polyester raw slivers,head draws and end draws was observed and analyzed,and various forms of fluorescent fibers were defined and classified.The fibers in the yarn sliver were divided into straightened fibers,broken fibers,zigzag fibers,0-degree back/front hooking fibers,acute angle back/front hooking fibers,obtuse angle back/front hooking fibres,2-end folding fibers,and 2-end acute angle hooking fibers.According to these 18 types of observed fluorescent fiber states,and the proportion of various forms of fibers was obtained,the results showed that the proportion of posterior hooking fibers in the green sliver was the largest,and more than 50%of the fibers were shown as posterior hooking fibers,and the proportion of front hooking fibers was about 10%,which was much lower than that of the back hooking.This was due to the configuration of the comb needle between cylinder and doffer and the relationship between specifications and carding,and therefore the probability of various fibers on the cylinder to be transformed to the upper back hook of the doffer was gr
