Abstract: An apparatus for dyeing a textile substrate using a plurality of applicators that each apply an increment of a total dye application. In one form a reduced indigo dye in a leuco-state is applied in an inert atmosphere substantially isolated from oxidizing substances. In another form the foamed dye is applied while open to the atmosphere. In both forms holddown rollers or inverted applicators are located between applicators at decreasing depths to minimize increases in tension as the substrate travels over successive applicator faces.

Abstract: A method and apparatus for space dyeing yarn includes a series of dye stations each of which has a dye applicator roll and a rotatable pattern roll having deflecting rods which may deflect yarn into engagement with the periphery of the respective dye applicator roll. 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.

Abstract: A method and apparatus for space dyeing a plurality of strands of yarns which are fed over a series of dye applicator rolls. Each roll is rotated in a partly submerged condition in a dye pan containing a different color. Above and offset relative to each dye applicator roll is a yarn pattern roll which carries a number of slats in a circumferential array extending beyond the periphery of the pattern rolls for contacting the yarn strands. The slats sequentially engage and deflect the yarn strands onto the surface of the respective dye applicator rolls. The slats may be positioned in selected slots in the pattern rolls to determine the pattern of color applied to the yarn. Variable speed drives rotate the dye applicator rolls and the pattern rolls independently of each other to effect the spacing of the colors and the amount of dye received by the yarn strands.

Abstract: A process and apparatus is disclosed for dyeing an elongate textile material with different colors at predetermined intervals in a substantially continuous, uninterrupted cycle of operation. The apparatus comprises a plurality of dye baths exchangeable one with another, a nip and guide roll assembly rotatable into dyeing position in timed relation to the particular dye bath which has been exchanged; an orienting guide roll assembly carrying thereon a plurality of guide rolls and a cam plate adapted to retract one of the guide rolls away from the path of dyed material, and a cylindrical drum drier having a plurality of apertures for the passage of dyed and undyed materials, respectively.

Abstract: This invention provides a method and an apparatus for direct formation of a stripe pattern on a textile substrate such as sliver. The object of the invention is to dispense with a gill which would interfere with a high-speed feed of said textile substrate and thereby improve the efficiency of coloration. In accordance with this invention, a color supply hollow drum 2 and a color suction hollow drum 3 are vertically juxtaposed and a continuous length of fibrous material is continuously fed between said two drums 2, 3 by rotation thereof. As the substrate material is thus fed, a color composition is supplied from color supply grooves 8 of the color supply hollow drum 2 while it is drawn by a suction force acting in color suction grooves 13 of the color suction hollow drum 3 to cause the color composition to strike through the fibrous substrate material to thereby form color stripes of substantially the same configuration as that of the above-mentioned grooves on the fibrous substrate material.

Abstract: A system for color printing and processing multiple yarn fibers by mechanized means in response to programmed signals derived from a computer control devise indicative of fabrics having select patterns or designs. The system includes data gathering implements including a sample pattern to be duplicated for producing a program for color printing. The computer receives the data and processes it to produce signals indicative of the color program. A control device receives the signals from the computer and initiates control voltages for driving a color printer which color prints yarns passing therethrough in accordance with the program. The colored printed yarns are processed through fixing apparatus to fix the colors and thereafter separated into individual yarn fibers and stored for immediate or future use in looms, weaving machines and the like.

Abstract: Dye is applied to the lower surface of a dye pickup roll for transfer to the pile surface of a length of carpet, and a squeegee roll engages the dye pickup roll after the dye has been applied to the pickup roll and before the dye is transferred from the pickup roll to the carpet. The external surface of the squeegee roll is approximately cylindrical with a multiple number of depressions formed therein, and the squeegee roll can be rotated and reciprocated with respect to the dye pickup roll, so that its high spots tend to wipe or "squeegee" the liquid dye from the surface of the dye pickup roll and its depressions or low spots tend to permit the dye to pass beyond the squeegee roll on the pickup roll in a pattern and move with the pickup roll into contact with the pile surface of the carpet. When the squeegee roll is reciprocated, it tends to prevent the pattern from being repeated on the dye pickup roll and on the carpet.

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.

Abstract: Sizing of a yarn sheet is practiced without direct immersion into a size bath through running pressure contact of same with a rotary sizing roller while the process is so automatically controlled that, at starting of the sizing operation, the drive for running of the yarn sheet starts after all the related working elements are registered at their operative positions and, at stopping of the operation, the elements are released from the registered operative positions after the yarn sheet has come to a complete stop.

Abstract: An apparatus for washing freshly spun artificial yarn during its movement relates to the finishing of yarn such as viscose yarn. By this apparatus, yarn is intermittently saturated with a finishing solution on that portion of a rotating roll which extends outside the finishing solution contained in a tank. Between the saturation zones, the yarn is spaced apart from the roll surface for diffusion and squeezing of yarn. In order to ensure the intermittent saturation of yarn with the finishing solution, the yarn is displaced in the direction opposite to the rotational direction of the roll. An additional roller engages with the driven roller displacing the yarn so as to form a squeezing pair therewith, and there is an additional tank having a scraper. The scraper is in permanent contact with the roll surface below the zone of feeding the yarn thereto and is adapted to remove the layer of finishing solution from the roll surface.

Abstract: An improved method of dyeing carpets and the like and apparatus for carrying out the method in which a dye film of a width equal to that of the carpet is formed and then interrupted in a varying manner to result in strips of dye being deposited on the carpet in a random fashion to obtain a visually pleasing effect.
