Article Preview

Rheological properties of blend spinning solution of sodium alginate and carbon black (SA/CB) were investigated. The results reported that blend spinning solutions were non-newtonian fluids. The apparent viscosity and structural viscosity index increased with increasing CB content in SA spinning solution, but the non-newtonian index decreased, both demonstrated the blend solution was sensitive to shear rates. Blend spinning solution with 6% CB had large flow activation energy (Eη), so the temperature must be controlled exactly in spinning. Temperature had similar impact on sample spinning solutions: the apparent viscosity decreased when it increased. Study on dynamic rheological behavior shows SA/CB blend spinning solutions had greater die swell ratio and worse flowability than pure SA solution, but the flowability of blend solutions could be regulated by changing temperature.
