用旋转粘度计研究了废醋酸纤维素(WCA)丙酮溶液的流变性质,考察了溶液对切变速率,增塑剂含量、浓度和温度的依赖关系,并对可纺性进行了研究。研究结果表明,WCA丙酮溶液的粘弹性低于CA丙酮溶液;WCA丙酮溶液的可纺性良好。
The rheological properties of waste cellulose acetate (WCA) acetone solution were investigated by rotational viscometer. The dependence of solution on shear rate, plasticizer content, concentration and temperature was investigated. The spinnability was also studied. The results show that the viscoelasticity of WCA acetone solution is lower than that of CA acetone solution; the spinnability of WCA acetone solution is good.
