Abstract: The novel method relates to dyeing a textile article with medicinally rich herbs to produce natural, unique, deep and fast coloured textile articles having medicinal effects shield the human skin. Successive stages of dyeing include desizing, bleaching, scouring, galling, mordanting, dyeing, washing, colour fixing and finishing. The textile article is pretreated with camel/buffalo/cow dung, Myrobalans and Alum for fixation and development of colour and finally with extract of herbs for dyeing. Salts of copper, chromium, tin and iron can also be use as mordants to modify the shade. In yarn dyeing, drying is done by hanging on a bamboo stick in sunlight and for even penetration of dye yarn is continuously rotated in a dye solution. Novel herbal dyes, methods and cloths made thereof, in chemical free, detergent free, non hazardous, eco friendly, pollution free, having anti-allergic, antiseptic and antimicrobial functions are disclosed.

Abstract: The invention concerns the use of indoline derivatives of formula (I): in which R1, R2, R3, R4 and R5 independently of one another represent hydrogen or C1-4 alkyl groups, or R4 and R5 together with the oxygen atoms to which they are attached represent a C1-4 alkylenedioxy group, or of salts of such indoline derivatives, as additives to hair dyeing agents of the direct dyeing or primary intermediate/secondary intermediate type, thus producing hair dyeing with excellent color fastness characteristics.

Abstract: Micro-particles of transition metals or their compounds can be generated as an integral part of a fiber by first attaching a nucleating agent to the fiber, and then adding a solution of metal ions. The ions are reduced by the nucleating agent in the fiber, and micro-particles are generated in or on the fiber. Because of the strong color signal resulting from a low concentration of metal micro-particles, the method is cost effective even when using gold or titanium ions. Various colors were generated by changing the size and spacing of the micro-particles, the metal or metal complex used, and the characteristics of the fiber. The dyed fibers displayed colors ranging from pink, red, purple, yellow, orange, peach, brown, gold, silver, grey, green, and black. These colors resisted bleaching by either chemicals or light.

Abstract: This invention comprises a hair dyeing composition based on oxidation dyestuff precursors which dyes and brightens the hair containing, besides at least one developing and at least one coupling agent, at least one metal salt and at least one ammonium compound selected from the group ammonium chloride, ammonium sulfate, ammonium carbonate, ammonium bicarbonate, and ammonium carbamate, having a pH-value between 8 and 11, preferably from 9 to 10, after admixture with an oxidizing agent in the ready-to-use preparation.

Abstract: In a method for the oxidative dyeing of human or animal hair a hair dyeing agenet is prepared from at least one oxidation dye in creme or gel form, which is adjusted to a pH of 5.9 to 6.9.The preparation is performed with the addition of at least one alkali metal salt or alkaline earth metal salt as catalyst, which is added simultaneously with or immediately after the mixing of the oxidation dye with the oxidizing agent, the amount added being such that it is contained in the treatment-ready hair dyeing agent in proportions between 0.0001 and 1.00 wt.-%, preferably between 0.0004 and 0.001 wt.-%.

Abstract: Liquid formulations of mixtures of cationic dyes frequently have a very short storage life. As a consequence, these formulations give rise to customer complaints concerning incorrect dyeing strengths and hues and concerning isoluble constituents. It has now been found according to the invention that powder formulations and in particular liquid formulations of cationic dyes or of mixtures of these dyes can be stabilized by adding selected oxidizing agents.

Abstract: Artificial leather and a dyeing method therefor; the leather includes ultrafine polyamide fibers and is particularly a grained artificial leather having bright, deep color, good color fastness to dry cleaning with charged soap, a delicate touch free from any undesirable rubber-like feeling, as well as high durability.A super-entangled fiber base is provided comprising ultrafine polyamide fibers and/or bundles thereof; polyurethane including polyoxyethylene of molecular weight of 500-5,000 is applied. The polyamide ultrafine fibers are dyed with a metal-dye complex and a fixing agent.

Abstract: A propylene oxide polyadduct containing carboxyl groups, or a salt thereof, obtained from(a) an adduct of propylene oxide and an aliphatic alcohol having 3 to 10 carbon atoms which is at least trihydric,(b) an aliphatic dicarboxylic acid or the anhydride thereof having 2 to 10 carbon atoms or a mono- or di-lower alkylester of said dicarboxylic acids,(c) an aliphatic diol having an average molecular weight of at most 2,000,(d) a fatty acid having 8 to 22 carbon atoms and(e) an aromatic dicarboxylic acid or the anhydride thereof having 8 to 12 carbon atoms; it is in particular useful as dyeing assistant for the dyeing of fibrous material made of or containing wool with anionic dyes.

Abstract: In the printing of dyes onto substrates, the pretreatment of the substrates with low levels of calcium or sodium salts or other gelling/insolubilizing agents effectively reduces dye usage.

Abstract: A vapor process for mineral dyeing cotton textiles is disclosed. Cellulosic fabric is impregnated with a chromium solution, exposed to sulfur dioxide vapors, dried, cured, and washed. The result is a superior process to "pearl gray" mineral dye fabric. Chromium containing salts used in the pad bath are selected from the group consisting of (NH.sub.4).sub.2 Cr.sub.2 O.sub.7 ; K.sub.2 CrO.sub.4 ; (NH.sub.4).sub.2 CrO.sub.4, Na.sub.2 CrO.sub.4 ; Na.sub.2 Cr.sub.2 O.sub.7 ; and K.sub.2 Cr.sub.2 O.sub.7. The pad baths contain from about 3.5% to 5.0% chromium consisting of 40 to 50 parts of a 20 to 28% sodium dichromate dihydrate solution made alkaline with 25 to 50 parts of 10 to 20% sodium hydroxide solution to attain a pH of about 9.6 to 13.0 with about 0.5 parts of wetting agent and 0-30 parts of water. A pad bath comprising about 3 parts of ammonium dichromate, 7.5 parts ammonium carbonate, 0.6 parts zirconyl ammonium carbonate and 0.

Abstract: A process of dyeing or printing of synthetic fiber materials by means of disperse dyes carried out in the presence of at least one derivative of a metal having an atomic number in the range of 24 through 30 to prevent or diminish the degradation of the dye during the dyeing or printing process, and ready-to-use colorant compositions for this process.
