  • Patent number: 11353425
    Abstract: A method for measuring the attraction propensity of fabric including the steps of charging a neutralized test fabric, optionally by contacting with a charging fabric, presenting the charged test fabric a predetermined distance from a static-influenced agent such that at least a portion of the static-influenced agent attaches to the charged test fabric, and determining the quantity of attached static-influenced agent.
    Type: Grant

  • Publication number: 20150299949
    Abstract: A process for dyeing textile fibers employs a colorant medium comprising a disperse dye and an aqueous dispersion of a copolymer selected from vinyl ester-based copolymers, alkyl acrylate copolymers, alkyl methacrylate copolymers and mixtures thereof. The textile fibers are passed through at least one dye bath containing the colorant medium to deposit the colorant medium at least on the surface of the fibers. The fibers with the colorant medium deposited thereon are then passed between padding rollers to distribute the colorant medium through the fibers, whereafter the fibers are heated to cure the copolymer and bond the disperse dye to the fibers.

  • Publication number: 20140150187
    Abstract: Disclosed herein is the preparation of indigo-dyed cotton denim fabrics suitable for use in making cotton denim garments and other denim articles. These indigo-dyed fabrics are prepared from cotton warp yarn which has been pre-treated with an emulsion copolymer prior to being contacted with an aqueous dye liquor comprising a dispersion of an indigo dyestuff. Such copolymer-treated cotton warp yarn can be woven or knitted into cotton denim griege fabrics along with untreated cotton weft yarn. Such griege denim fabric can then be indigo-dyed using the aqueous dye liquor. Alternatively, the emulsion copolymer-treated cotton warp yarn can be indigo-dyed by contact with the aqueous dye liquor before this warp yarn is incorporated into denim fabric along with the untreated cotton weft yarn. The cotton denim fabric produced by either method has the appearance of conventional ring-dyed indigo fabrics.

  • Patent number: 6217621
    Abstract: Matrix-dyed textiles of cellulose acetate, cellulose triacetate, silk, wool, flax, nylon, acrylic, polyethylene terephthalate, cotton, and rayon are stripped of their dyes in a dye stripping system comprising a reducing agent in an aqueous bath produced by the reaction of a bisulfite with about 0.35% or less of a borohydride by weight of the textile. The borohydride may be added to an aqueous bath already containing the bisulfite and the textile or the borohydride and bisulfite may be mixed in an add tank and the mixture added to the aqueous bath. Chelating agents, sequestering agents, fire retardants, and odor scavengers are not needed. Reclaimed textiles having superior receptivity of a new dye are provided.
