Effect of Supercritical Carbon Dioxide Dyeing Procedure on Mechanical Property of Wool Fiber

摘要

In this paper, the effects of dyeing temperature, pressure, and time on mechanical property of wool fiber were investigated in supercritical carbon dioxide fluid. In addition, On the basis of single factor experiment, the optimal technological conditions for dyed wool fiber was optimized by employing Box-Benhnken Design experiment, and the optimal conditions were as following: dyeing temperature 110 °C, dyeing pressure 25 MPa and dyeing time 75 min.
