摘　　要：加捻三角区是环锭纺成纱过程中一个重要区域,其几何形态影响加捻三角区中纤维张力的分布以及成纱性能。通过在FA507B细纱机上纺制29.2 tex棉纱,并借助高速摄像机,对不同锭速和不同胶辊前冲量下的加捻三角区形态进行拍摄,测量出加捻三角区的宽度W、高度H以及加捻收敛点与纤维束中心线间的偏移距离d,确定加捻三角形的几何形态,然后对不同加捻三角区中纤维张力进行数值模拟。最后结合数值模拟结果对不同锭速以及胶辊前冲量下成纱进行定性分析。The spinning triangle is a critical area in the spinning process of staple yams. Its geometry influences the distribution of fiber tension in the spinning triangle and the properties of spun yams. In this paper, 29.2tex cotton yarns were spun by using the frame of FA507. With the help of high speed camera system, the shape of spinning triangles in different spindle speed and different advanced value of cot were captured. The width, the length and offset distance between the center line of the yam and the twisting point of the spinning triangle were measured. The distributions of fiber tension were simulated and the qualities of yarns were measured and analyzed.
