松式络筒工艺设计与质量控制 摘要 供染色的筒纱比普通的筒纱要求更高，特别是要求筒纱的密度均匀一致、有非常精密的无重叠的纱线层、锭长锭径更加准确、纱线的退绕更好，这种卷装在染色过程中具有最佳的液体渗透性。本文对影响筒纱密度及均匀性的相关因素进行了实验分析，对相关工艺参数进行了优化。得出了以下结论： 松式络筒速度不影响筒纱密度；臂压力对密度的影响较大，一般在密度相差较大时优先考虑调整臂压力；张力是控制筒纱密度的关键因素，在筒纱密度相差不大时进行微调；超喂的目的是充分释放张力，根据纱线品种的不同可选择不同的超喂比；交叉角主要是配合软边表消除硬边和方便下道工序退绕，一般情况选择精密型，根据纱线品种可选择不同的交叉角。交叉角一般不宜选择太大；温湿度对松式卷装密度影响较大，一般要控制它的稳定性。 关键词： 密度 臂压力 超喂 交叉角 张力 Abstract Soft winders for dyeing than ordinary demanding, especially the requirements of uniform density winders package, there is no duplication of sophisticated yarn layer diameter ingot ingot length is more accurate and better yarn around the back, This volume in a dyeing process of the liquid permeability of the best. In this paper, effects of density and uniformity Soft winders other relevant factors that the experimental analysis of the relevant process parameters were optimized. Drew the following conclusions: Soft winders does not affect the speed of winding density; arm pressure on the density of the larger, more general difference in the density when the pressure to give priority to the adjustment arm; winders package tension is to control the density of the key factors, an insignificant difference in the density of Soft winders When fine-tuning; the purpose of feed roller the full release of tension, according to the different choice of yarns of different varieties of feed roller ratio; cross angle is in line with the soft side of the main table to facilitate the elimination of hard-edged and procedures under the Unwinding generally choose precision type, in accordance with choice of different varieties of yarn cross angle. Angle cross-general should not be too much choice; temperature and humidity on the pine-style volume density greater impact in general to control its stability.
