摘　　要：为制备结构性能优良的喷气涡流纺包芯纱,以粘胶短纤维作为外包纤维,不同种类聚酯长丝(涤纶拉伸变形丝(DTY)、涤纶全拉伸丝(FDY)和聚对苯二甲酸丁二酯纤维长丝(PBT))为芯丝制备喷气涡流纺包芯纱。比较分析了不同种类芯丝喷气涡流纺包芯纱与纯粘胶喷气涡流纱的性能差别,并采用双因素方差分析法探究了芯丝种类与纺纱速度对包芯纱强伸性、条干CV值和毛羽H值的影响情况。研究结果表明:相较于不含芯丝的喷气涡流纺纱线,包芯纱的力学性能明显提升,毛羽H值有所降低;芯丝种类是影响喷气涡流纺包芯纱性能的主要因素,对断裂强度、断裂伸长率和毛羽H值影响极为显著,以DTY为芯丝的包芯纱断裂强度最大,以PBT为芯丝的包芯纱断裂伸长率最大,以FDY为芯丝的包芯纱毛羽H值最低;纺纱速度仅对毛羽H值有显著性影响,3种包芯纱的毛羽H值都随纺纱速度的增大而增大,其中PBT包芯纱毛羽H值增长速率最快。Objective In order to optimize the structure and performance of core-spun yarns made by air-jet vortex spinning,the paper reports on the effects of core filament types and delivery speed on yarn properties,so as to better predict yarn properties and guide the product development of core-spun yarns based on air-jet vortex spinning.Method The core-spun yarns were prepared using viscose staple fiber as the sheath and different polyester filaments,including polyester draw textured yarn(DTY),polyester full draw yarn(FDY),and polybutylene terephthalate filament yarn(PBT),as the core filament.Through studying the yarn performance test and scanning electron microscope(SEM)images,the differences between different types of core-spun yarns and pure viscose yarns made by Murata vortex spinning were compared and analyzed,and the effects of core filament types and delivery speed on the core-spun yarn tenacity and elongation,evenness CV value and hairiness H value were investigated using two-factor ANOVA.Results Due to the existence of core filaments,the mechanical properties of the air-jet vortex spun core-spun yarns are significantly improved than that of staple yarns(Tab.3).The ANOVA results showed that the type of core filaments were the main factor affecting the performance of core-spun yarns and had a significant effect on breaking strength,elongation and hairiness H value;In the considered range,the delivery speed only had a significant effect on the yarn hairiness H value,but had no significant effect on the yarn strength,elongation and evenness.The interaction of filament types and delivery speed had a significant effect on the breaking strength of core-spun yarns(Tab.4-7).At any delivery speed,the core-spun yarns containing DTY filaments had the highest breaking strength.Although the strength of PBT filament was second only to DTY filament(Tab.1),the breaking strength of PBT core-spun yarn was the lowest among the three core-spun yarns.The reason is that the excessive difference in elongation at break between filament
