摘　　要：为进一步拓展喷气涡流纺纱线品种及提高传统色纺纱加工效率,利用Box-Behnken设计实验方案,借助软件Minitab 16,分析喷气涡流纺工艺参数对竹浆纤维色纺纱性能的影响。结果表明:成纱工艺对色纺纱断裂强度的影响较为复杂,其中纺纱速度及纱线线密度对色纺纱断裂强度的影响受喷嘴气压不同取值影响;色纺纱条干不匀主要受纺纱速度和纱线线密度影响,提高纺纱速度使纱线条干不匀先减后增,而减小纱线线密度将显著恶化色纺纱条干;色纺纱毛羽主要受喷嘴气压和纺纱速度影响,降低喷嘴气压及提高纺纱速度均会使纱线毛羽增加;色纺纱直径主要受喷嘴气压和纺纱线密度影响,增加喷嘴气压或减小纱线线密度,均会使色纺纱直径明显减小。For further increasing the variety of air jet vortex spun yarn and enhancing the processing efficiency of the conventional color spun yarn, experimental schemes were designed by Box-Behnken method. The software Minitab 16 was introduced to analyze the influence of process parameters of air jet vortex spinning on properties of bamboo pulp fiber colored spun yarn. Research results showed that the influence of yarn formation process on the tenacity of bamboo pulp fiber colored yarn spun based on air jet vortex spinning is rather complicated, in which, the effect of yarn delivery speed and yarn linear density on the yarn tenacity depends on the change of nozzle pressure. The evenness of the colored yarn is affected principally by yarn delivery speed and yarn count. Increasing yarn delivery speed makes yarn＇s evenness value decrease first and then increase. However, decreasing yarn linear density will significantly deteriorate yarn evenness. Yarn hairiness is influenced mainly by nozzle pressure and yarn delivery speed, and more yarn hairiness exhibits when decreasing nozzle pressure and increasing yarn delivery speed. Yarn diameter is affected primarily by nozzle pressure and yarn count. Enhancing nozzle pressure and decreasing yarn linear density result in obvious decrease of yarn diameter.
