Studies on union dyeing of acetate and viscose blended fabrics

Abstract

In accordance with the I. C. I. diagrams obtained from the previous five reports, 50-50 % acetate and viscose blended fabrics were dyed solidly with acetate and direct cotton dyes by the so-called “one bath method.” In this report, objects which corresponds to a combination of the x-y coordinates and brightness (Y) of the given dyed textile were set at first, then the blending ratio of the dyes were determined by means of the I. C. I. diagram (Ex. I), and fabrics were dyed. In most cases slight colour differences were observed between the object and the dyeings. So the blending ratio of the dyes was amended and fabrics were dyed again (Ex. II). Thus, trials were carried on until (Ex. III), and the result very close to the object was obtained. Six colours were tried in the same way, but this method may be utilized in the wider range of the diagram. © 1955, The Society of Fiber Science and Technology, Japan. All rights reserved.
