探讨竹浆纤维棉混纺涡流纱的生产工艺.针对竹浆纤维特点进行原料加湿预处理,较好地解决了生产中的静电现象.采用条混工艺以保证准确的混纺比.开清棉采用“短流程、多松少打、多梳少落”的工艺原则；梳棉采用“轻定量、低速度、紧隔距”的工艺原则,减少棉结和短绒；并条工序合理配置牵伸工艺；涡流纺工序对牵伸倍数、喷嘴压力、喷嘴与前罗拉隔距等工艺参数进行优选,最终顺利纺制出了竹浆纤维/棉70/3014.7 tex混纺涡流纱,质量达到了较好的水平.%Processing of bamboo fiber cotton blended vortex yarn was discussed. According to bamboo fiber property, raw material were pre-wetted, electrostatic phenomena in production was solved well. Sliver blending processing was adopted to ensure blending ratio correctly. In opening and picking process,short production line,more loosing less beating and more carding less noil were adopted. In carding process,lighter weight per unit,lower speed and less gauge were adopted to reduce neps and short fiber content. In drawing process, draft was set rationally. In vortex process, draft multiple, nozzle pressure, gauge between nozzle and front roller et al were optimized. Finally bamboo/cotton 70/30 14.7 tex blended yarn can be spun successfully, the quality can reach better level.
