Patent number: 5601621Abstract: Fiber materials can be modified by applying heterocycloaliphatic compounds containing at least one primary, secondary or tertiary amino group or quaternary ammonium group, the hetero portion of which in the ring is a carbonic ester radical of the formula --O--CO--O-- or a carbamic acid radical of the formula --O--CO--NH--, in aqueous alkaline solution by exposing the fiber material to these compounds at a temperature of between 60.degree. and 230.degree.

Patent number: 5167668Abstract: 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.Type: GrantFiled: November 26, 1990Date of Patent: December 1, 1992Assignee: Hoechst AktiengesellschaftInventors: Manfred Hahnke, Pablo Canora

Patent number: 5085668Abstract: On testing triphendioxazine reactive dyes it was found that they are unsuitable for almost all conventional single-step printing processes since they are not stable under these conditions.In the course of the development of an uncomplicated single-step printing process for these dyes, it has been found according to the invention, then, that by replacing the customary fixing alkali (NaHCO.sub.3) by stoichiometrically specific amounts of sodium acetate or sodium trichloroacetate or certain mixtures of sodium trichloroacetate and sodium acetate it is possible to fix triphendioxazine reactive dyes in full yields without change in hue. In addition, it is possible to print conventional print pastes.Type: GrantFiled: October 24, 1990Date of Patent: February 4, 1992Assignee: Hoechst AGInventors: Gerhard Pelster, Wolfram Schidlo
