【摘要】 本文采用40、45、52毫米三种纺杯直径和30°、45°、60°三种凝棉槽角度对纺制27.8、58号棉纱的质量情况进行了正交试验。通过试验得到,在纺杯速度50000转/分条件下,纺杯直径以45毫米为好;在用含杂较少的原料时,中支纱以用较小角度凝棉角对提高纱的强力有利等的一些看法。更多还原

【Abstract】 The crossed test for the quality of OE spinning Nm 27.8 and 58 count cottonyarns are espectively made by using three kinds of rotor diameter (40, 45,52mm) and three kinds of ondenser groove angle (30°, 45°, 60°) , By mea-ns of these tests, some cognitions are btained: when the rotor speed is at50,000 rpm, the result of 45mm dia, rotor is better; when he material con-tents less impurity, spinning medium count yarn with smaller condensing g-roove angle is of interest for yarn strength etc,更多还原
