Theoretical maximum dye-uptake of acrylic fiber to basic dye

  • Huei-Hsiung Wang


The theoretical maximum dye-uptake of the fiber to dye is considered to be related to the fraction of the polymer segment which is mobile. This is studied by dyeing the acrylic fiber at temperatures within a 40 °C range while treating the samples with different carriers. The relation of the equilibrium dye-uptake (dyeability) of the acrylic fiber to the structural parameter, \({\int_{20}^{\text{T}} {{\left( {\tan \delta } \right)}_{{\text{c}}} {\text{dT}}} }\), with the presence or absence of carrier in solution, is linear, confirming the validity of the hypotheses, where (tanδ)c is the loss tangent correlated at a temperature of 20 °C. Moreover, The effect of the carrier in swelling the amorphous region of the acrylic fiber was less effective as temperature rose beyond T g(mechanical).
