  • Patent number: 7131158
    Abstract: A process for forming a spaced dyed yarn, where a yarn is conveyed to a dye application station where a coordinated stream of dye is projected in a normal stream path adjacent to a first side of the yarn. The dye is applied to the yarn when a gas nozzle projects a stream of gas such that it impinges the stream of dye and diverts the stream of dye across said yarn to an alternative deflected path adjacent to the opposite side of said yarn, causing the dye to sweep over the yarn and impact and color the yarn. Upon deactivation of said gas nozzle, the stream of dye passes back across said yarn to the first side of the yarn, impacting and coloring the yarn for a second time.

Each pattern roll is rotatably driven by a servo motor and selectively rotated to position the deflecting rods for permitting dyeing to occur at the respective station and to rotate the roll and thus the rods to angular dispositions where the yarn is not deflected. A programmable controller controls the respective motors to the selected angular positions at precise times to start and stop the application of dye to the yarn. An encoder associated with the yarn feed system feeds timing signals related to yarn movement to the controller so that rotation of each pattern roll is in timed relationship with the movement of the yarn.

A counter roller supports the waffle grid at the printing station, and an oppositely disposed protuberance-bearing pressure roller pushes the backing of the carpet so that the pile enters the compartments of the waffle grid and is immersed in the dye pattern. The protuberances ensure adequate immersion of the pile while permitting escape of air and avoiding squeezing of the dye from the pile, which would otherwise occur by engagement of the pressure roller with the grid walls in the absence of the protuberances. The angle of approach of the carpet to the printing station is slightly inclined from the horizontal to ensure a gradual depression of the pile and to avoid rolling the dye out away from the nip region of the printing station.

  • Patent number: 4153961
    Abstract: Multiple strands of undyed yarn are fed continuously from supply spools or bobbins supported on a creel to a skein winding apparatus. The strands each pass along a substantially horizontal path through one or more spaced dyeing stations where they are engaged by an oscillating frame and caused to oscillate laterally back and forth from said paths while streams of dye individual to the yarns are continuously directed onto the yarns from a series of overhead tubes at the dyeing stations. The strands thus periodically interrupt the dye stream of the associated tubes and receive dye at a multiplicity of spaced portions along their lengths with intervening portions of the yarns remaining uncolored. The space dyeing can be varied by changing the speed of movement of the yarns, by varying the amplitude and speed of movement of yarn guide means which produces the lateral oscillation of the yarns and by selectively operating varying numbers of dye stream feeders at one or both dyeing stations.

  • Patent number: 4108595
    Abstract: A method for coloring fabrics with coloring agents producing unique decorative patterns thereon by pleating the fabric, distributing the coloring agents onto the pleated fabric, fixing the coloring agents to the fabric, and then unpleating the resulting colored fabric. Also disclosed is a method for producing a simulated printed effect upon a flocked fabric which has been flocked in a pre-determined design pattern and impregnated with a wetting agent prior to the said pleating step. Fabrics obtained by such methods are also described.

  • Patent number: 4086688
    Abstract: A roll of knit tubing, which has been knit into a tubular shaped prefabric in the first stage of a knit/deknit process, is presented successively to one or more dyeing stations while in a rolled or coiled package. Dyestuff is applied to the roll at selected positions on at least one side surface thereof in such amounts as to form regions of dye which spread in all directions through a plurality of convolute layers. The dye and stitch are then simultaneously heat set in an autoclave and the tube deknitted according to conventional practices to provide a textured yarn having random color variations therein.

  • Patent number: 4063888
    Abstract: Yarn is space-dyed by a process wherein the yarn is wound around a receptacle, e.g., a perforated package dyeing tube. A dyebath is allowed to flow through the yarn. The flow of dye is partially restricted or channeled in such a manner that the yarn becomes intermittently dyed.

  • Patent number: 4052155
    Abstract: Chevroning of fabrics made from skein dyed yarns is avoided or controlled by dyeing the yarns such that the color repeat length is greater than the circumference of the skein. In practice this is achieved by horizontally dyeing only a portion of the width of a skein as the skein is held vertically.

  • Patent number: 4047271
    Abstract: A method for space dyeing yarn wherein a rapidly advancing yarn is intermittently deflected into and out of a nip of a pair of rotating dye applicator rollers, such that those portions of the yarn which pass through the nip are subjected to a rapidly applied and substantial compressive force in the nature of a hammer-like impact in the nip, to cause the dye carried by the rollers to deeply penetrate into the yarn. In the illustrated embodiment, the yarn is advanced past a plurality of such pairs of dye applicator rollers, and an external pattern control acts to deflect the yarn into and out of the various nips in accordance with a predetermined program.

  • Patent number: 4042989
    Abstract: Method for packaging and dyeing yarns comprising the steps of winding at least one yarn on a provisional core, at the same time imparting to the yarn a continuous rotation and a rciprocating translation, and to advance the wound yarn continuously so that it comes off the said core. The tubular packaging that continuously comes off its support core has brought to bear on it a plurality of jets or sprays of dye directed radially, over the entire circumference of the packaging.

  • Patent number: 4033717
    Abstract: Drawn but undyed synthetic continuous filament yarn is formed into a prefabric, selected portions of the prefabric are dyed while leaving other selected portions free of any dye, the prefabric is raveled, the resulting partially dyed yarn is formed into a partially dyed prefabric, and this partially dyed prefabric is then substantially completely over-dyed to produce a novel over-dyed fabric.This method produces a novel form of crimped and drawn continuous filament synthetic polymeric yarn, a substantial portion of which is undyed, and the balance of which consists of random, intermittent dyed lengths consisting of at least two different colors (A and B) intermittently and randomly arranged along the length of the yarn.

  • Patent number: 3992142
    Abstract: A process and apparatus system for continuous printing of fabric includes a water surface in a vat on which dye materials are formed into a uniform film and fabric is contacted therewith. The film forms in a tiltable tray like container extending the full width of the vat of water and dyes are distributed thereon by compressed air nozzles which tilt with the tray devices. A baffle feeds fabrics into the water during the process.

  • Patent number: 3976426
    Abstract: Yarn is wound back and forth around a given axis to form a tightly wound package, whereupon dye is fed into the bottom of the package, with the axis thereof vertically arranged, and forced to flow radially outwardly through the bottom turns of the package to take up the dye and color at least the lower end of the package. Alternatively, water will first be similarly fed through the package adjacent the bottom thereof, the wicking action of the yarn carrying the water to a level above the top level to which dye is then fed through the yarn in the manner stated. The wicking action of the water prevents the application of the dye from extending above the top level at which the dye is supplied to the package, thus giving a sharp color cut off, whereas with the unwatered package, the application of the dye is such that the wicking action carries the dye to a higher point, the intensity of the color progressively diminishing upwardly.
