An attempt was made as to compare original dyeability between wet-spun formalized vinylon and cellulosic fibers such as viscose rayon and cotton. The dye on fiber and the color-depth and the color-shade of wet-spun formalized vinylon, that fineness and tenacity approximated to those of the viscose rayon and cotton with each other, were measured, and the following results were obtained. The dye on wet-spun formalized vinylon in the formalizing bath containing sodium sulfate, in the standard dyeing condition were equal to other fibers, but the color-depth and the color-shade on the dyeings were inferior to the properties of other fibers. The color-depth on dry-spun formalized vinylon is better than the dyeability of viscose rayon, and it almost approaches the property cotton has.
