Abstract
An attempt was made to clarify whether there is a structural factor governing the dyeability of poly(ethylene terephthalate) (PET) fibers by disperse dye or not, and if so what it is. Five PET fiber samples having a wide degree of amorphous packing (n) distribution, F′(n), as determined from dynamic loss tangent-temperature curves in an αa dispersion region using Manabe and Kamide’s method, were prepared by changing spinning velocities and annealing conditions. PET fibers were dyed with the three different disperse dyes under various conditions and the dye uptake W was determined colorimetrically. The upper limit of n, denoted as nu°, above which the dye molecule can not penetrate through amorphous regions, was evaluated as functions of dyeing conditions from the plots of W against obtained for various assumed nu. It was confirmed that the plots of W vs. G(nu°) give a single master line, irrespective of the various fiber preparing conditions or dyeing conditions; for Resolin Blue FBL W=67.6·G(nu°)−0.4 (mg-dye/g-fiber). This indicates that the dyeability of PET fibers by the disperse dye is unambiguously governed by the amount of the amorphous region, whose degree of amorphous packing of n is not larger than nu°.
