摘要
本文利用毛细管流变仪研究了几种二醋片（ＣＡ）丙酮纺丝原液的流变性。分析了粘流活化能（ΔＥη）与可纺性的关系．认为ΔＥη可作ＣＡ－丙酮纺丝原液可纺性的表征参数．ΔＥη越小，可纺性越好．ΔＥη大于８０ＫＪ．ｍｏｌ－１时，可纺性差．
The rheology properies of the cellulose acetate prefered by high temperature method (HTCA)aceton solutions are studied by capillaty rheometer,Having been analysed the ralations of the activation energg of the Viseous flow(ΔEη) of the solutions,it shows that ΔEη can be used as Characteristic perameters of the spinnability of CA-acton Solutions,and the ies the ΔEη value of the solution,the beffer its spinnability.When ΔEη>80KJ·mol-1,the spinnability is Poor.
