摘 要: | 用旋转粘度计研完了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、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。

STUDIES ON THE REGENERATION OF WASTE CELLULOSE ACETATE (WCA) FOR THE FILAMENTS OF CIGARETTE FILTER TOP 2. RHEOLOGY AND SPINNABILITY OF WCA ACETONE SOLUTION |

Abstract: | The rheological properties of the WCA acetone solution are studied by RHEOTEST-Ⅱ which is used to detetmine the influences of shear rate, concentration, temperature and the contents of plasti-cizers on the flow curves as well as on the spinnability of the solution. The lesults confirm that the spinnability of WCA solution is good and its viscoelasticity is lowe than that of the o-iginal CA. |
