Abstract: A single, uniform application of dye is employed to generate a pattern dyed substrate wherein the pattern and pattern-complementary areas are dyed by the same dye, but at different levels of fixation. Dye is uniformly applied to the substrate, and optionally dried, without fixation. Heat is applied to the substrate uniformly as well as selectively in a pattern configuration. The uniform heating serves to fix the dye in the pattern-complementary areas at a pre-determined level. Selective heating in pattern areas serves to fix the dye at a higher level of concentration in pattern areas than is found in the pattern-complementary areas, resulting in a multi-tone effect. Optionally, the heating in pattern areas may be sufficient to cause shrinkage or other thermally-induced physical modification to the substrate, in perfect registry with the pattern-dyed areas.

Abstract: A new and unique method of producing a mosaic-like work of art on a sheet of fabric material. Once the fabric and its basic color is selected, a coating of melted wax is applied to one surface thereof. After the wax is dry, the fabric is crackled so as to form random and skewed cracks. Dye is then applied which penetrates the cracks and is absorbed by the fabric, whereby random skewed lines are left in the fabric after the wax is removed. The random skewed lines define a multiplicity of contiguous areas to be selectively painted so as to render a mosaic-like work of art.

Abstract: A continuous process for dyeing a carpet in which spaced regions of the tufted side of a pre-wetted carpet are first compressed in a desired pattern. The tufted surface is then covered with a viscous water-soluble gum, and drops of a less viscous gum are then applied to the viscous gum-wetted tufts. Next, drops of a viscous dye are applied to the tufted surfaces and then a less viscous dye is applied over the entire tufted surface of the carpet.

Abstract: A continuous process for dyeing a tufted carpet includes the step of dyeing the entire carpet, in one dye color, with a first, relatively low viscosity dye. The carpet is then vibrated to cause the tufts to stand up. The entire tufted surface of the carpet is then coated with a relatively viscous second dye. Drops of a third dye, which is less viscous than the second dye and substantially more viscous than the first dye are then applied over the more viscous second dye coated tufts. A fourth dye which is substantially less viscous than the second and third dyes is then applied over the entire tufted surface of the carpet.

Abstract: A continuous process for dyeing a pre-wetted carpet includes the step of printing, in one dye color, a desired pattern on the tufts, compressing those of the tufts receiving the dye in the process. The tufted printed surface of the carpet is then covered with a viscous water-soluble first gum and drops of a second dye, which is less viscous than the first gum, over the viscous gum-wetted tufts. Drops of a water-soluble second gum which is less viscous than the first gum, are then applied to the tufted surface and then a third dye which is substantially less viscous than the second dye is applied over the entire tufted surface of the carpet.

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 textile-printing industry is very interested in bypassing the laborious and expensive production of transfer printing papers, together with the required engraving of rolls. It has been found that this demand can be satisfied by electronically recording and reproducing any motif and transferring to textile material by means of halftone systems.According to the invention, the dyestuffs are continuously transferred by halftone systems from four differently and uniformly colored papers one after the other. To obtain a good picture, 10 to 20 halftone dots per cm are advisable for pressing the paper to the surface of the textile material. Either the halftone dots themselves are heated, or they press the textile material and paper onto a heated surface. The halftone dots are electronically actuated in correspondence with the scanning of the motif.

Abstract: Two linear arrays of foamed dyestuff dispensing nozzles reciprocate 180.degree. out of phase normal to the path of a carpet web being dyed. Each array dispenses streams of foamed dyestuff over a gum coated web in alternate groups of first and second colors, the second array dispensing its dyestuff superimposed over the dyestuff dispensed by the first array. The same dyestuff color groups overlap in spaced repeating regions of the carpet web while different colors overlap in the remaining regions to provide a fully dyed web having the appearance of repetitive spaced regions of either the first or the second colors.

Abstract: A method is disclosed for permanently patterning a textile fabric with a visually pleasing random-appearing network of line segments, as well as the fabrics produced thereby. The fabric is preferably calendered on at least one side, then packed into a heated chamber via a multi-stage folding or pleating process. The packed fabric is retained in the heated chamber a sufficient time to heat set the network of creases generated by the packing process. The fabric may then be dyed; creased portions of the fabric appear more saturated with dye.

Abstract: Two or more liquid treating agents which are to be applied to a stationary or running substrate are formed ahead of a collecting unit which thereupon admits a foamed compound composition into the applicator wherein the composition passes through the interstices of a screen so that it is reconverted into a liquid prior to contacting the substrate. The collecting unit can comprise or may be followed by a mixer, depending upon whether or not the constituents of the compound composition are to be converted into a homogeneous foam. The collecting unit receives discrete streams of foamed treating compositions, e.g., in the primary colors, from discrete foam generators each of which is followed by a storing device and by a regulating device, such as a valve which is adjustable by hand and/or by a computer.

Abstract: There is described a process for producing, in a continuous manner, a gradient dyeing across the width of a long strip of a plastic sheet and an apparatus used therefor. In a preferred embodiment of the invention, the orientation of the plastic strip is maintained substantially constant during the passage through a dye bath, and the dye liquid level is repetitively varied by use of a liquid level control means. This invention is particularly useful for making gradient-dyed plastic sheets which in turn are used for making sunglass lenses.

Abstract: An improved process for dyeing closely constructed non-tufted textile materials is provided wherein an effective minor amount of a substantially oil and water repellent fluoropolymer is applied to the textile material. The substantially oil and water repellent fluoropolymer employed can be represented schematically as ##STR1## The textile material can be, if desired, scoured with an aqueous surfactant solution to remove any residual dirt, oil or processing aids present on the textile material and thereafter scoured with an aqueous acidic solution to provide the textile material with an acidic pH prior to application of the fluoropolymer. Further, the back portion of the textile material can be backcoated with an elastomer composition. Once the textile material has been treated using any of the above processing steps, in combination with the application of the fluoropolymer, the resulting polymer-modified textile material is thoroughly dried and cured prior to dyeing.

Abstract: Pile fabrics with a pile containing thermoplastic fibres are thermoprinted with a pattern, the contact pressure between the pile fabric and the thermoprinting web in the heating zone being such that about 40 to 60% of the pile is compressed, and immediately afterwards relief-formed and/or surface formed while still hot with a pattern which bears a strict relationship to the thermoprinted pattern. A machine for carrying out this process comprises a thermoprinting unit with adjustable contact pressure and a relief-forming and/or surface forming patterning unit which functions in synchronism and coordination therewith.
