    Abstract: Systems and methods for dyeing inherently flame resistant fibers, and particularly aramid fibers, without the use of accelerants or carriers. Fabrics made from aramid fibers or blends thereof are immersed in an aqueous dye bath that includes at least one dye and at least one acid component. The temperature of the dye bath is increased from room temperature to a suitable temperature (e.g., between approximately 285° F. to 400° F.) capable of rendering the aramid fibers less crystalline so that the fibers can accept the dye. In this way, suitable color yields may be obtained without the use of accelerants or carriers as have been required in the past.

    Abstract: Range-dyed fabrics that possess excellent hand characteristics and simultaneously exhibit substantially nondirectional appearances are provided. Such a combination permits the production and utilization of an extremely comfortable apparel fabric that can be attached to any other similar type of fabric to form a target apparel article without the time-consuming need to align such component fabrics to ensure an overall aesthetic appearance is met for the target apparel article. In general, such a fabric is produced through the initial immobilization of individual fibers within target fabrics and subsequent treatment through abrasion, sanding, or sueding of at least a portion of the target fabric. Such a procedure produces a fabric of short pile height and desirable hand. Upon range-dyeing the target fabric exhibits the extra benefit of nondirectional surface characteristics.

The fabric is then passed over steam drying cans to reduce the moisture level to 8-10%. Subsequently, the fabric is passed through a first compressive shrinking machine, a scrubbing operation and then through a final compressive shrinking machine.

  • Publication number: 20010054209
    Abstract: A method for dyeing cellulosic materials with reactive dye by pretreating the fabric with a polycationic polymeric agent which is desirably also polynucleophilic is disclosed. The agent can be a polyquaternary amine material especially a poly(DADMAC) or polyvinylpyridine, particularly one including nucleophilic sites such as primary amino groups, e.g. polyallylamine/DADMAC copolymers and polyvinylpyridines quaternisied with w-aminoalkyl groups. The dyes can react with the nucleophilic centres so dyebath exhaustion can be driven by dye fixation rather than substantivity to the substrate. The need to use of salts to drive substantivity can be obviated and post dyeing washing to remove unreacted/hydrolysed dye is much simplified. Material dyed by the method has the good wash fastness properties of materials dyed using reactive dyes. A wide variety of cellulosic substrates can be dyed including lyocell fibre materials and blend/union materials with polyamides.

    Abstract: Textiles are first manufactured to attain dimensional stability and durability and thereby withstand the rigors of industrial rental and commercial laundering. Then, the garments are dyed in a two-stage process to yield outstanding colorfastness, pilling resistance, dimensional stability and durability. Garments are yielded that, even after extensive use, may be overdyed to custom colors in custom-sized batches to extend the useful life of stained or otherwise discolored garments. By performing the dyeing and/or overdyeing portions of the process at a location near the end user of the textile, transaction costs related to transportation of goods are minimized, technical resources are efficiently utilized, and large inventories of dyed garments need not be maintained, thereby reducing inventory expenses.

  • Patent number: 5695375
    Abstract: Novel regenerated cellulose fiber dyeable with disperse dye is disclosed. In this regenerated cellulose fiber, 10 to 40 weight % of polyester fine particles or styrene-acrylic polymer fine particles having an average particle size of 0.05 to 5 .mu.m are compounded. Products wherein the regenerated cellulose fiber and polyester fiber are used in combination can give dyed products excellent in homochromatic properties, and since both fibers can be dyed at the same time, the dyeing efficiency is remarkably improved.
