Abstract: A process for making multi-colored fabrics from a single dye formula is described. The process involves providing a substrate including synthetic fibers, with the substrate having defined regions where the synthetic fibers have differing levels of fiber orientation, and dyeing the substrate with a dye bath containing at least one dye from at least two of the categories of a) high contrast dyes, 2) medium contrast dyes and c) low contrast dyes, to thereby produce a multi-colored substrate from a single dye formula. The substrates are characterized by having a base of a first color and patterned regions of a different color, with the regions of different colors corresponding to regions of different levels of fiber orientation.

Abstract: A dye composition is disclosed, which comprises a blue anthraquinone dye of the following formula (I) wherein Y is —CH?CH2, —CH2CH2Cl or —CH2CH2OSO3H; and a gray-black azo dye of the following formula (II) wherein Y is defined as the above. The dye compositions of the present invention have good stability and build-up property. The dye compositions are suitable for dyeing and printing materials that contain either cellulose fibers, such as cotton, artificial cotton, linen, and artificial linen, or synthetic polyamide, such as wool, silk, and nylon. The materials obtained through treatment with the dye compositions aforementioned show excellent properties, especially in wash-off, level-dyeing, build-up, light fastness and perspiration-light fastness.

Abstract: Garments are constructed from lyocell fabric which has been resinated using a textile resin having just two groups per molecule which can reactively cross-link with cellulose molecules of the lyocell fabric then causticised by application under tension of an aqueous solution of sodium hydroxide, and the constructed garments are dyed in a garment dyeing operation. Garments can be produced by this route which retain a smooth, evenly-dyed appearance with unpuckered seams and minimal creasing and so present a desired formal look, as distinct from the casual look imparted by the effects of fibrillation normally produced when lyocell garments undergo garment dyeing.

Abstract: A process of dyeing a molded article is disclosed. The process entails immersing at least a portion of the article in a dyeing bath, retaining the portion in the bath for a period of time sufficient to allow an amount of dye to diffuse into the article, and removing said article from the bath. The molded article comprises a polymeric resin such as (co)polyester, (co)polycarbonates, acrylonitrile-butadiene-styrene, polyamide, polyurethane, polyalkyl(meth)-acrylate, allyldiglycol carbonate and styrene copolymers. The dyeing bath contains in addition to dye, water, a plasticizing agent and a leveling agent.

Abstract: Durable antimicrobial treatments for textile fabrics are provided. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. This particular treatment requires the presence of a resin binder, either as a silver-ion overcoat or as a component of a dye bath mixture admixed with the silver-ion antimicrobial compound. Such a treatment is extremely durable on such substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its antimicrobial activity. The particular treatment method, as well as the treated textile fabrics are also encompassed within this invention.

Abstract: The method for simultaneously dyeing and permanent shaping of hair includes dividing the hair into strands an winding the strands onto curlers: mixing a hair shaping component (A) containing from 6 to 15 percent by weight of a keratin-reducing substance with a dye component (B) to form a dyeing and shaping composition prior to application on the hair; treating the hair with the dyeing and shaping composition and then allowing it to act on the hair for an acting time sufficient for the permanent shaping; after that, treating the hair with a fixing composition; allowing the fixing composition to act on the hair from 1 to 40 minutes and then subsequently rinsing the hair. The dye component (B) contains at least one oxidative coupler compound and at least one oxidative dyestuff selected from a group consisting of certain 4,5-diamino-pyrazole derivatives and certain aminophenol derivatives.
