In order to shorten the process time of conventional preparing agents and continuous operation, to make superfluous neutralizing agents for removing excess peroxy compounds as well as to reduce the mechanical equipment required vis-à-vis prior art and to reduce the use of chemical agents, the cellulose material soaked with the treatment liquor is continuously dried with pulsated air at approximately the same disintegration rate as the peroxy compounds thus used. Alkali remaining in the material from pretreatment which remained in the material is used for dyefixing said material.

Abstract: A process for dyeing cellulosic containing textile materials with fiber reactive dyestuffs whereby from the scouring thru the after-scouring's final rinse less than 5 hours are required and only from 5 to 6 liquor baths are used. Material to be dyed is prepared for dyeing in 10 to 15 minutes at the boil, dyeing is performed in the next bath with no intermediate rinse. Glacial acetic acid, auxiliaries, and dyestuffs are added to the dye bath along with specified amounts of electrolyte, and after the required dyeing temperature is reached specified amounts of alkali are added to the dye bath and the materials subjected thereto at proper time-temperature relationships for level dyeing of a particular shade. Dyestuffs, electrolyte, and alkali are added to the dye bath in one portion with no dosing in a time period of from about 5 to 10 minutes each. The material is neutralized and soaped simultaneously.

Abstract: The present invention is a fully automated modified batch dyeing process that provides a process that reduces water consumption, reduces environmental pollution, and reduces the energy and chemical consumption of the conventional batch dyeing process through efficient reuse of spent dyebath. The invention provides a holding tank which stores the spent dyebath, and an analysis system which allows for the analysis of the dyebath in the holding tank so that the dyebath may be reconstituted and used in the batch dyeing process.

Abstract: The invention relates to a process for the two-step direct dyeing of keratin fibres, comprising bleaching the keratin fibres; and applying to the keratin fibres a dye composition comprising at least one partially dissolved basic direct dye and an aqueous medium, wherein the dye composition is ready to use or results from mixing, at the time of use, at least one pulverulent composition (P) comprising at least one basic direct dye and an aqueous composition (A).

Abstract: Hair upon the scalp or eyelashes are treated with hair coloring or mascara compositions in hair or eyelash coloring methods. The hair is typically colored with a mascara brush to achieve streaking and a non-homogenous coloring of the hair upon the scalp or the eyelash. A copaiba resin and a metal containing pigment are combined to obtain the hair coloring product. The resultant product is applied to the hair upon the scalp or the eyelash to effect coloring of the hair upon the scalp or the eyelash.

Abstract: In accordance with the present invention, there is provided a single-step process and composition of a category-2 hair bleach which can simultaneously lighten the hair up to seven levels, and effectively neutralize any undesirable warmth that accompanies the lightening process. This is achieved by including in the bleach composition disperse dye molecules which the present invention has found to be both, stable in the bleach, and capable of depositing the desired amount of various permanent tones on the hair. These disperse dyes do not stain the scalp of the client or the hands of the hairdresser, but are substantive only to the hair fibers. The dyes fall into the classes of anthraquinones and azo compounds.

Abstract: Economical, pollution-free treatment of textiles occurs in a low voltage electrochemical cell that mercerizes (or scours), sours, and optionally bleaches without effluents and without the purchase of bulk caustic, neutralizing acids, or bleaches. The cell produces base in the cathodic chamber for mercerization and an equivalent amount of acid in the anodic chamber for neutralizing the fabric. Gas diffusion electrodes are used for one or both electrodes and may simultaneously generate hydrogen peroxide for bleaching. The preferred configuration is a stack of bipolar electrodes, in which one or both of the anode and cathode are gas diffusion electrodes, and where no hydrogen gas is evolved at the cathode.
