Abstract:In order to improve the strength of air-jet vortex spinning viscose yarn，taking spinning R 16.9 tex yarn as an example，the raw material selection and the spinning process are introduced，the specific measures for the optimization of the process such as blowing-carding unit，drawing and vortex spinning，as well as the control standards of temperature and humidity in each workshop are emphasized.By comparing the main parameters and yarn quality before and after each process optimization，it is pointed out that the process of the opening and cleaning should follow the principles of frequent grasp and less grasp，more loose and less beating，comb instead of beating，less drop and more mixing.The process concepts of flexible carding，adequate transfer and optimal card clothing configuration are used in the carding process.The process configuration of low combining，small drafting，slow speed and large gauge in the drawing process is adopted.The spindle specification，nozzle pressure，and the parameters of electronic yarn cleaner and splicer are selected.The temperature and humidity of each workshop are controlled to meet the standard.After taking the above technological measures，the spinning quality of the air-jet vortex spinning R 16.9 tex yarn is obviously improved，the production efficiency is up to 99.0%，and the single yarn strength is increased by about 5.5%.
Key Words:air-jet vortex spinning；single yarn strength；viscose；blowing-carding unit；card clothing；drawing；straightness；parallelism；yarn cleaner；splicer
