- Title
Dyeing of Polyurethane Fibers with Traditional Classes of Dyes.
- Authors
Mishukova, A. S.; Safonov, V. V.
- Abstract
A new method consisting of diazotization followed by azo coupling with azotol is proposed for dyeing polyurethane fibers. Unlike traditional methods, the new method does not require high temperatures and long treatment times. The effect of external factors on the intensity and fastness of the dyes obtained by the new method was examined, the reflectance spectra were obtained, and the K/S relations of dyed samples of polyurethane were calculated.
