As we know, finished polyester fibers are very difficult to dye, especially at low temperature (including room temperature).
An exception is processes for dying undrawn fibers. We have studied use of the crazing method to dye polyester fibers at low
temperatures with water-soluble dyes not having an affinity for polyethylene terephthalate. We have studied the effect on
sorption of cationic dyes from the composition, concentration, and temperature of the adsorption-active medium, and the dye
concentration in the dye bath. The results of the study are the basis for developing a production process for obtaining colored
special-purpose polyester fibers. 相似文献

The aqueous emulsion bath of cationic electrodeposition-colored coating was studied by cyclic voltammetry. The effects of pH and the distance between the cathode and anode on deposition potential and deposition current density were also observed. The deposition of colored coating was recorded by chronoamperometry, and the deposit was studied by UV/VIS absorption spectroscopy. The ratio of resin to pigment in the deposit was estimated from chronoamperometry. © 1998 John Wiley & Sons, Inc. J Appl Polym Sci 70: 2719–2727, 1998 相似文献

The kinetics of tin electrodeposition during the electrolytic coloring of porous anodic oxide films on aluminum is studied
as a function of the oxide properties, e.g., the thickness of the porous oxide layer, and the surface resistance offered by
the barrier oxide layer. While the thickness of the porous oxide layer is controlled by the anodization time, the surface
resistance is controlled by the anodization voltage, and the anodization bath temperature. Steady-state polarization measurements
are employed to characterize the dependence of the coloring kinetics on the oxide properties. Measurements indicate that the
kinetics of the electrolytic coloring process can be accelerated by: (i) reducing the surface resistance of the oxide film
(primarily offered by the barrier oxide layer) by growing the oxide at a lower anodization voltage, and/or a higher bath temperature,
or (ii) growing a thinner porous oxide layer by decreasing the anodization time. The electrochemical measurements are supported
by gravimetric analysis of electrolytically colored alumina samples (using calibrated wavelength-dispersive X-ray fluorescence
spectroscopy), and by optical spectrophotometry. 相似文献
