摘　　要：研究了明胶/聚乙烯醇复合原液流变性的各影响因素,如复合溶液的配比、温度、浓度和交联剂种类及用量等.结果表明:各复合溶液的非牛顿指数n均小于1,属于非牛顿流体中的假塑性流体,且随着温度的升高,n值不断增大.在所研究的明胶/聚乙烯醇复合原液中,随着浓度和交联剂用量的增大,其非牛顿指数n和结构黏度指数都均呈现增加的趋势.各配比下的明胶/聚乙烯醇共混纺丝原液均属非牛顿剪切变稀型流体.In this paper, the influenc of the collagen/PVA haviors was investigated, including the mass ratio between perature and crosskinkers. It was indicated that all blended composite solution on the rheological becollagen and PVA, solution at different concentration, temratio of collagen and PVA were non-newton pseudoplastic fluids. And with the temperature building-up, the non-newton coefficient increased. With the increasing of concentration and cross linker, the non-newtonian viscosity index and structure index of the mixed solutions increased.
