Finishing kinetics of acrylic precursor fibers was studied by using a new CGB-1 finish. Effects of different comonomers including vinyl pyrrolidone, acrylamide and methyl acrylate on finishing behavior of acrylic precursors were discussed. Diffusion coefficients of the finish were calculated by the Crank’s equation. It is shown that the precursor fibers with the CGB-1 finish do not have fluff, broken and adhered precursors. The increase of the finish uptake is greater around the glass-transition temperature and the change of uptake becomes less prominent as the finish bath temperature is above the glass-transition temperature. By use of comonomers, the finish uptake is enhanced, the diffusion coefficient of the finish is higher, the activation energy required for the finish is lower and the extent of decrease is the greatest for the fibers containing vinyl pyrrolidone. The properties of the finished precursor fibers containing polyvinyl pyrrolidone are the best.
