摘　　要：为缩短生丝加工流程并改进现有的缫丝成筒技术,在自动缫丝机基础上,借鉴络筒机的络交卷绕和张力控制等方法,开发出了一种新型的缫丝成筒设备及技术。通过正交分析法优化了缫丝成筒技术的工艺参数,并考察该缫丝成筒技术制备的缫丝成筒生丝与自动缫丝机制备的小生丝和小生丝经复摇、整理、泡丝、络筒等传统工序制备的传统筒装生丝在结构和性能上的差异。结果表明:对于选用的原料茧,当选择卷绕速度130 m/min、超喂比1.15、干燥温度90℃、油剂体积分数5%作为工艺参数时,该技术制备的缫丝成筒生丝同时具有相对较好的断裂强度、断裂伸长和抱合性能。缫丝成筒生丝的分子基团和结晶结构等微观结构、断裂伸长率、柔软性等力学性能与传统筒装生丝相近,而断裂强度、抱合指标要明显优于传统筒装生丝。新型缫丝成筒技术制备的筒装生丝优异的性能表明该技术具有良好的应用前景。Objective To shorten the raw silk process and improve the existing silk reeling techniques onto bobbins,a novel type of silk reeling machine was developed based on the automatic silk reeling machine.The new type of silk reeling machine was equipped with a single thread-controlled winding device and an active overfeeding device with an electromechanical integrated and compact structure.This research was set to investigate the optimization of the process parameters of the novel silk reeling machine and the properties of the raw silk.Method The process parameters were optimized using the orthogonal analysis method.We selected the winding speed,overfeeding ratio,drying temperature,and oil concentration as test factors,and the breaking strength,breaking elongation rate,and cohesion property of the raw silk prepared by the new silk reeling machine as test indexes.After the optimization,the differences between the raw silk on bobbins prepared by the new silk reeling technique onto bobbins,the raw silk on small reels prepared by the automatic silk reeling machine,and the traditional raw silk on bobbins prepared by processes such as re-reeling,finishing,foaming,winding were investigated.Results In the optimization experiment of parameters,the winding speed showed a very significant effect on the breaking strength and breaking elongation rate of the raw silk.The overfeeding ratio and drying temperature have a significant or very significant effect on the breaking strength,breaking elongation rate,and cohesion property of the reeled raw silk.However,the oil concentration has no significant effect on the breaking strength and breaking elongation rate of the raw silk.It only has a very significant effect on the cohesion property of the raw silk.For the selected raw material cocoons,when the winding speed is 130 m/min,the overfeed ratio is 1.15,the drying temperature is 90℃,and the oiling concentration is 5%,that is,when they are used as the optimal process parameters,the raw silk on bobbins prepared by the new type of silk
