纱线中纤维路径的图像检测与分析

开发了手工控制图像测试技术以获取纱线内纤维路径的空间位置.将所得数据分类,得到一张纤维转移特征图.结果发现,纤维不完全转移占主导地位;纱线内跟踪纤维的3D路径表明纤维转移具有螺旋特征.纤维角度的分布或变化情况证实了纱线内部纤维的转移取决于纱线的捻度.

Model to Study Resin Impregnation Process of Premix Made of Friction Spun Core Yarn

A model was developed to investigate impregnation behavior of thermoplastic resin into filament bundle based on Darcy's law. Consolidation processes of unidirectional laminate were performed to evaluate the validity of the model. Friction spun core yarns were used in the experiments with polypropylene fiber sheath and glass filament core. The processing conditions, such as temperature and pressure, and filament parameters were taken into consideration. A good agreement was found between theoretical prediction and experiment data.     

不同混合比玻璃纤维/丙纶网络纱的拉伸行为

对不同混合比及不同供气压力的玻璃纤维／丙纶（GF／PP）网络混纤纱进行拉伸测量，包括抗拉强度、断裂伸长率、模量．通过实测值与经典理论估计值对比分析，结合其拉伸曲线，得出混纤纱的实测强度大致符合经典理论估计．并认为该种混纤纱宜采用较低含量的丙纶以保证玻璃纤维的应用特征，最终断裂点特征不必过高关注．

Study on Misplating Problems of Composed of Wool and Lycra Plated Knitted Fabrics

By a great deal of experiments,the misplating problemsof plated knitted fabrics composed of wool and Lycra arediscussed and analyzed.The factors affecting the mis-plating problems on manually operated flat knitting ma-chine include the construction and adjustment of a plat-ing feeder,wool yarn count,feeding tension,takedowntension and the ground fabric structures.Some usefulresults can be derived from these works.     

Computation and Measurement of Winding Tension in Ring Spinning

By studying the variations of balloon height and of wind-ing radius in any one winding layer of ring spinning, the formula for determining the winding tension in any layer is derived, and then the overall tension variation throughout all winding layers can be computed. A meth-od of measuring the winding tension is also introduced here, with the measured results agreeing with the com-puted ones, and so the reliable relationship between winding tension, speed and ring traveller weight can be thus obtained. The highest allowable spindle speed is also discussed.
