Research on Polypropylene Dyeing in Supercritical Carbon Dioxide

Abstract:

Article Preview

Polypropylene fibers were dyed with Disperse dyes Blue 2B in Supercritical Carbon Dioxide at different temperature, pressure and time. The K/S value were determined and the effect of as temperature, pressure and dyeing time on the dyeing behaviours of disperse dyes on Polypropylene fibers were discussed. It was found that with the increase of dyeing temperature and pressure, the K/S value increased gradually, and dyeing effect was best after the fiber was dyed at 120 °C, 28 MPa for 20 min.
