摘要： Indigo-dyed garments are treated with an anti-ozone agent to prevent ozone-related degradation of the garments before laser finishing. Without treatment, the garments can exhibit color loss (e.g., color change or fading) from exposure to ozone in the atmosphere. The indigo-dyed garments with anti-ozone treatment can serve as base templates in a laser finishing process flow. The anti-ozone treatment of the base templates can include a rinse including an ascorbic acid or vitamin C constituent during a base preparation process. Then quantities of these base templates can manufactured and stored for periods of time without exhibiting ozone-related degradation effects.

摘要： A dyeing and welding process may be configured to convert a substrate into a welded substrate having at least some color imparted thereto via a dye and/or coloring agent by applying a process solvent having a dye and/or coloring agent therein to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may include a binder, such as dissolved biopolymer (e.g., cellulose). After application of a process solvent comprised of a dye and/or coloring agent, the substrate may be exposed to a second application of a process solvent comprised of a binder, which second application may occur before or after a process temperature/pressure zone, process solvent recovery zone, and/or drying zone.

摘要： A dye fixing section in a foam indigo dyeing machine for dyeing traveling sheets of textile yarn. The dye fixing section receives traveling sheets of yarn to which indigo dye in leuco form has been applied and penetrated partially through the yarn. Oxygen is applied to the substrate to set the dye at the level of penetration achieved as it enters the dye fixing section, to produce yarns in the sheet with outer dyed rings and undyed cores.

摘要： Ring dyeing of yarn with indigo dye to produce an improved white core, An outer surface of the yarn is scoured prior to applying the indigo dye, and then applying the indigo dye is applied. Scouring parameters of the dyeing are used to limit a penetration of the indigo into the white core, so that the white core has mostly sections of white yarn, and the yarn has indigo dye on the outer surface, said parameters comprising limiting scouring parameters to at least 10% below current parameters used to scour the yarn.

摘要： Processes and apparatus are disclosed which substantially eliminate the formation of oxidized indigo dye before and during dye application onto a natural fiber yarn or fabric while allowing the leuco-indigo dye molecule to diffuse fully into the natural fibers of the yarn where it can fix to the fibers prior to oxidation (i.e., exposure of the leuco-dyed yarns to oxygen). Indigo dyed textile products (e.g., dyed cotton yarns that may be twill woven to form a denim fabric) exhibit exceptionally high colorfastness as determined by the AATCC Crock Test.

摘要： Described herein are methods of dyeing fibers, and dyed fibers and textiles made using the methods. The methods involve contacting a fiber with a dye liquor at a dye liquor temperature of about 30° C. to 115° C. to form a dyed fiber, wherein the dye liquor components include at least N,N′-diacetyl indigo and a salt solution having ionic strength of about 0.03 M (moles/liter) to 1 M and pH of about 3 to 8 at 20° C. The contacting is generally carried out for a contact period of about 10 seconds to 30 minutes, for example by immersing the fiber in the heated dye liquor. By using the disclosed methods, N,N′-diacetyl indigo is substantially uniformly distributed on the dyed fiber to provide intense, vibrant colors affixed thereto. Dyed textiles display substantially uniform color.
