THE DYEING OF TENCEL .2. SULFUR DYES

Four CI Solubilised Sulphur dyes were applied to cotton, regular viscose and Tencel at 2%, 6% and 10% o.m.f. and the colour strength and colorimetric parameters of the dyeings determined. It was found that the colorimetric parameters of all the dyes on the three types of fibre reflected those of the undyed substrates and, in general, that there was relatively little difference in colour between the dyeings on the three fibre types. The colour strength of the dyeings.-was lowest on cotton, the dyeings on Tencel being of slightly lower colour strength than those on viscose. From the results, it appears that Tencel exhibits similar dyeability to cotton with such solubilised sulphur dyes.
