Abstract: Durable antimicrobial treatments for high pressure treatments (such as package dyeing) for specific dyed yarns for further incorporation within 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 as a component of the dye bath formulation admixed with the silver-ion antimicrobial compound, the formulation then forced through a target yarn spool in order to provide a finish over substantially all of the target yarn. The yarn may then be knit, woven, pressed, laid-in, etc., into a textile fabric exhibiting antimicrobial properties. Such a treatment has been found to be 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.

Abstract: Coupling products of diazotized o- or p-toluidines to 3-hydroxy-2-naphthoic acid p-anisidide do not produce optimum dyeing properties in HT exhaustion dyeing of wound packages of synthetic fiber materials. Filtration occurs time after time under critical conditions, since these single dyestuffs and also mixtures of these with one another build up too slowly in the heating-up phase.A bright red multi-component system of the same color shade, which exhibits a significantly improved exhaustion capacity by synergism during HT dyeing of wound packages and no longer presents difficulties in respect of filtration, can be obtained by mixing monoazo dyestuffs which are obtained by coupling diazotized aniline and p-toluidine in each case to 3-hydroxy-2-naphthoic acid p-anisidide.

The machine does not produce in excess nor does it produce substandard quality.

Abstract: The method comprises the steps of impregnating spooled threads with a cold treatment liquid inside a kier, leaving an air cushion above the liquid inside the kier, discharging the liquid from the kier through a liquid discharge outlet by feeding steam above the air cushion, stopping the discharge when the steam reaches the liquid discharge outlet, and treating the spooled threads with steam inside the kier.

Abstract: Method and apparatus for the high speed, multicolor dyeing of yarns to obtain uniformly dyed lengths of different color along the length of the yarns, wherein a moving strand is collected in a plurality of layers on the surface of a winding drum while a plurality of streams of dye of different color are continuously applied in metered amounts onto the outer surface of the yarn on the drum to form radial bands of color in the collected yarn. The drum is rotated at high speed to cause radial outward flow of dye from inner yarn windings into the outer yarn windings on the drum, thereby providing uniform penetration and coloration of the yarn by the dyes. Dye centrifugally expelled from the outer surface of the yarn is collected and removed by an outer housing peripherally surrounding the drum. The traverse speed of the yarn traverse mechanism of the drum is independently variable to permit the dyeing of yarn sections of selectively variable lengths.

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.
