Abstract: In textile products (e.g. yarns, woven fabrics, knit fabrics) comprising highly crosslinked polyacrylic fibers (made of acrylic fibers by partially hydrolyzing a nitrile group to generate an amido group and a carboxylic acid group), fibers blended with the highly crosslinked polyacrylic fibers can be dyed in an even hue. A pre-dyeing treatment process for such textile products (e.g. yarns, woven fabrics, knit fabrics) comprising highly crosslinked polyacrylic fibers comprises a pretreatment step of immersing the textile product into an acidic solution and treating it at a high temperature and an elevated pressure. A dyeing process comprises the steps of conducting this pre-dyeing treatment process, and thereafter conventionally dyeing fibers blended with the highly crosslinked polyacrylic fibers. A pretreated and undyed textile product and a dyed textile product are obtained by the pre-dyeing treatment process and the dyeing process mentioned above, respectively.

Abstract: In an existing isothermal dyeing process, the alkali required for dye fixation is added to the neutral dyebath under linear or progressive program control. In this process, the amount of alkali added per unit time is small at the beginning and is increased progressively and in accordance with a program. This process passes through a certain (non-controlable) initial phase until the start of dye fixation on the cellulose. As a consequence the rate of fixation passes through a maximum before gradually decreasing when the final state of the dyeing is reached. To shorten the initial phase (waiting time) of dye fixation and to slow down dye fixation during the steepest part, it has proved advantageous according to the invention to add the alkali in accordance with a parabolic program.
