Abstract: A dye solution for dyeing polyester fabric including dye, a liquid carrier, an acidic agent, and a thickening agent. The carrier is selected to enhance the permeability of the polyester fabric at a certain temperature so that the dye can penetrate within the fabric. A method of printing designs on polyester fabric including creating a dye solution with water, a dye, a carrier liquid and an acidic solution. The dye solution is applied to the fabric in a desired pattern. The fabric and dye solution are then dried in as drier so that the temperature of the carrier is raised to permit the carrier to enhance the permeability of the fabric and have the dye penetrate the fabric. The carrier is then driven out of the fabric by the dryer and no pressure is applied to the fabric during the drying process.

Abstract: Intermittently colored yarns having an intermittent and random dye spacing pattern, and systems and methods of making the same, are disclosed. Such intermittently colored yarns exhibit higher quality and lower manufacturing costs over the known intermittently colored yarns. The intermittent coloring takes place while the yarn is in caterpillar form. Carpets made from such intermittently colored yarns exhibit enhanced aesthetics over carpets made from known intermittently colored yarns. Alternatively, a stain resist, colorless base dye, or bleaching agent can be applied in the same intermittent and random spacing pattern to the intermittently colored yarns prior to subsequent dyeing. This creates a mirror image like color effect to the resulting yarn.

Abstract: A method of forming a distinct pattern in an article of apparel formed of fabric, including the steps of: impregnating a viscous blocking agent into the fabric of the article of apparel in the distinct pattern; treating at least a portion of fabric surrounding the blocking agent in the distinct pattern to alter a color of the portion of fabric surrounding the blocking agent; and removing substantially all of the blocking agent from the article of apparel.

Abstract: Fabrics, formed, for example, by joining stitch and loop yarns to form a fabric prebody, with the loop yarn forming in loops that overlay the stitch yarn at the technical face and back of the fabric prebody, and thereafter finishing the fabric prebody to form raised fleece at both surfaces, have a first surface and an opposite, second surface of contrasting, i.e., different, colors. Regions of one or both surfaces may be treated to resist raising so that design elements of the raised or fleece regions stand out in relief, forming surface(s) with contour. Methods of forming the fabrics are also described.

Abstract: Addition polymers suitable for imparting stain resistance to nylon carpets and other polyamide products are formed of styrene or other ethylenically unsaturated monomer containing cyclic hydrocarbon groups, sodium vinyl sulphonate or other ethylenically unsaturated strong acid monomer, and ethylenically unsaturated weak acid monomer that is preferably acrylic acid. The proportions of the monomer are, respectively, 7 to 50%, 1 to 20% and 40 to 90% by weight.

Abstract: This invention relates to a process for the production of resist prints on two-dimensional textile materials, which is characterized by the steps of impregnating with a water-repellent those parts of one side of a textile piece which are to be given a resist effect, drying said textile piece and dyeing the textile piece by applying an aqueous liquor to the reverse side.

Abstract: There is disclosed a process for producing multicolor or tone-in-tone effects on natural and synthetic polyamide fiber material by subjecting flocks, slubbing, yarn or selected areas of piece goods to a plasma or corona discharge treatment before dyeing and subsequently dyeing the pretreated material with an anionic dye.Dyeings with very good differentiation of depth of shade on homogeneous polyamide fiber material are obtained by the process of this invention without the addition of resist agents or levelling agents.

Abstract: Azo dyes having the formula ##STR1## wherein the substituents are as defined in the specification and are useful for dyeing or printing textile materials.

Abstract: This is a method for producing multi-colored polyamide dyeings which is particularly useful in the multi-colored dyeing of polyamide carpets. In this method, a three-component dyeing system is employed which comprises a fiber reactive dye, an anionic resist and an acid-type dye. The anionic resist is a water-soluble, fiber substantative compound which displaces and/or prevents the fiber-reactive dye form fixing in that portion of the carpet which has been treated with the resist. The anionic resist, however, will not displace the acid-type dye component nor does it prevent fixation of the acid-type dye component. The invention may be practiced by first printing the polyamide substrate in a predetermined pattern with a printing paste containing the acid-type dye and the anionic resist. The substrate is then flooded or blotch printed with the fiber reactive dye and steamed to fix the dyes. Alternatively, the substrate may be first flooded or blotch printed with the fiber reactive dye.

Abstract: Process for producing pattern effects when dyeing or printing textile material in the absence of alkali or reducing agents, which comprises pretreating the textile material with a cationizing agent, drying, applying an oxidizing agent in the form of a pattern, drying and dyeing or printing with reactive, direct, acid, water-soluble sulfur dyes or pigment dyes in the absence of any alkali or reducing agent.

Abstract: A method for patterning a textile fabric in which a hydrophobic composition is uniformly applied to the surface of the fabric, and the resulting product. A high velocity water stream is used to wet areas of the fabric comprising the pattern areas. An aqueous dye is then applied uniformly to the fabric. The unfixed dye is retained by the fabric in those areas wetted by the water stream, the fabric is then treated to fix the retained dye.

Abstract: A textile substrate is dyed by immersing it in a gathered configuration into an oil medium containing a dissolved or dispersed dye for a sufficient time to allow the oil medium to come into contact with part but not all of the surface of the substrate and the thus-treated substrate is then preferably immersed in an aqueous medium having another dye dissolved or dispersed therein.

Abstract: A method of producing characters, symbols, patterns (hereinafter referred to as "characters, etc.") on a thermoplastic resin molded article is characterized in that in order to produce characters, etc. on the molded article, a dye-impenetrable cover is first applied to that part of the surface of the molded article which corresponds to the characters, etc. to be produced, impregnation dyeing being then affected on the molded article surface including at least the peripheral area of the covered part of the surface by using a sublimative dye, the cover being subsequently removed, whereby the characters, etc. are produced as such.

Abstract: A tinted soft contact lens such as a hydrated hydrogel lens having a variegated iris pattern is prepared by forming an iris pattern on the lens with a viscous paste which can contain an unoxidized vat dye. The lens is treated with a developer solution to obtain a tinted lens having an iris pattern which can be clear or different in color or in hue from the surrounding iris area.

Abstract: A hair-reserving penetration dyeing of the leather side of wool- or fur-bearing skins is obtained by dyeing the wooled or fur skins in aqueous medium with hydrosoluble sulpho-group-containing sulphur dyes (a) in the presence of dye-substantive uptake assistant (b) and of non-ionic and/or anionic hydrophilic dispersants (c) and optionally in the presence of leather fatting agents (d).

Abstract: In the conventional discharge printing on polyamide fiber materials using acid dyes, above all, the very low wet and light fastness properties of the designs obtained in this manner are frequently an obstacle to the wide expansion of this interesting technique in practice. Applying this known patterning method for wool or nylon to resist prints made with reactive dyes being distinguished by better fastness level, does not always produce satisfactory white resist effects when, for example, sulfite compounds as the resist agent and reactive dyes having esterified .beta.-hydroxyethylsulfonyl groups as the reactive radical are taken into consideration; colored effects having a bright hue are not even possible at all in various cases.

Abstract: A continuous process for dyeing a pre-wetted carpet includes the step of applying a viscous water soluble gum layer over the tufted face of the carpet. Drops of first and second dyes less viscous than the gum are applied over the gum-wetted carpet face. A third dye which is substantially less viscous than the gum and the first and second dyes is applied over the entire tufted surface of the carpet.

Abstract: The present invention provides a process for dyeing an anionic dyeable substrate with reserve and/or multicolored effects, which process comprises(1) impregnating the substrate with a dyeing liquor containing an anionic dye having a K'-value.gtoreq.5(2) directly thereafter applying locally to the substrate a liquor or paste containing an alkoxylated fatty amine or polyamine having affinity for anionic dyes with a K'value.gtoreq.5 and optionally a disperse dye and/or an anionic dye or an anionic optical brightening agent with the proviso that the anionic dye or optical brightening agent has a K-value at least one unit lower than the K'value of the anionic dye used in step (1), and(3) subsequently submitting the substrate to a heat treatment to effect fixation of the dye(s) and, if used, optical brightening agent.

Abstract: A transfer sheet comprising, in laminated combination, a substrate sheet and, provided thereabove, a coloring layer of desired pattern containing a coloring agent possessing heat transferability and a resist layer of a desired pattern containing a metal compound for resist printing and a binder, the metal compound having the capability of causing the coloring layer to lose its heat transferability, either of the coloring layer and the resist layer being nearer than the other to the substrate sheet. Because of the capability of the metal compound, the resist power is very great, whereby ample resist printing effect can be obtained with only an extremely thin resist layer.
