A system for treatment of thread includes a weft thread printer having an intake positioned to receive a weft thread from a source, as well as an encoder that is configured to detect a length of the weft thread as the weft thread moves through the weft thread printer along a travel path. The system also includes a printhead positioned to apply coatings of a plurality of colors to the weft thread and yield a treated weft thread, as well as an outlet positioned to pass the treated weft thread to a loom.

A textile wash cycle indicator system comprising a textile fiber or yarn or section comprising a dye system comprising at least one dye, the dye system configured to release an amount of the at least one dye during each consecutive wash cycle; wherein the release of the amount of the at least one dye correlates with the consecutive wash cycles, and a method of using same.

The present invention relates to a method of dyeing a textile, yarn or strand, in particular for use in footwear or apparel. The method may comprise the steps of: a) exposing at least a part of the textile, yarn or strand to a plasma field and a laser beam; and b) dyeing the textile, yarn or strand by digital dyeing, c) wherein the plasma field and the laser beam are at least partly overlapping to pre-treat the textile, yarn or strand prior to dyeing, and d) wherein the method is performed inside at least one of chamber(s). The present invention also relates to a textile, yarn or strand dyed according to the method of dyeing as well as to a system adapted for dyeing a textile, yarn or strand.

Provided is a method of manufacturing a mechanoluminescent fiber. The method includes the steps of: preparing an elastic fiber having a longitudinal groove on the surface thereof; forming a primer layer including a coupling agent on the elastic fiber; filling the groove of the elastic fiber with a mixture of a stress transfer substance and a stress luminescent substance; and forming a silicon adhesive layer on the elastic fiber of which the groove is filled with the mixture of a stress transfer substance and a stress luminescent substance. The silicon adhesive layer is 3-dimensionally bonded to the elastic fiber and the mixture of a stress transfer substance and a stress luminescent substance.

The invention discloses a waterless fiber dyeing method using supercritical carbon dioxide fluid as medium. Dry fibers are tightly loaded layer by layer in a porous yarn cage. After dyeing, the fibers are cleaned to remove unfixed dyes by an online way, thereby obtaining waterless dyed dry fiber products with good quality. With the supercritical carbon dioxide dyed by a dye, the invention can not only solve the problems of high energy consumption, high discharge, high pollution in the traditional dyeing process, but also obtain better dyeing effect. The invention has a simple process and convenient operation, which can effectively realize dry dyeing processing. The reaction is mild, avoiding the use of a large amount of water, heat and additives in high concentration, which has the features of being high efficiency and environmentally friendly.

Aspects are directed to a textile substrate with two or more ink layers and methods for printing a textile substrate. The two or more ink layers may include one or more visual components that form graphics or images that are visible to an observer when viewing the textile substrate from different angles.

Casings, dye tablets, DIY activity-kits include one or more casings, one or more encased dye tablets, or a combination thereof, that are configured to impart an artistic effect to an article, hydrographic sheets, and dip and decorator activity-kits including one or more hydrographic sheets and an instruction for imparting an artistic effect to the article using the one or more hydrographic sheets. The casings include at least one compartment formed of a water-soluble film, and one or more agents disposed within the at least one compartment. The encased dye tablet includes one or more agents compounded with a filler and a binder. The one or more agents include at least one colorant formulation and at least one fixative.

A method for producing a printed textile item is disclosed, the method including applying a pretreatment liquid containing a coagulant, water and a surfactant to a fabric, and, after the application of the pretreatment liquid, applying a white ink containing a white pigment and water to the fabric by an inkjet method, wherein a surface tension of the white ink at 0.05 Hz is within a range from 33 to 39 mN/m, a surface tension of the white ink at 10 Hz is 40 mN/m or greater, a specific gravity of the pretreatment liquid is greater than a specific gravity of the white ink, and the application of the white ink is performed within 100 seconds from the application of the pretreatment liquid and by a wet-on-wet method.

The application of melanin to fabric improves resistance to chemical pass-through, with possible application in protective garments, shelters, and filtration materials.

Methods for obtaining natural colorants from plant material (e.g., tobacco material) and for using such natural colorants to dye various substrates are provided. Natural colorants are obtained using particular enzymes and particular conditions (e.g., time, temperature, and pH profiles). Such colorants can be used to dye substrates, for example, using conventional dyeing techniques or using unique in situ methods.
