There is disclosed a method of coating textile fibers, the method comprising applying, on the external surface of textile fibers, a pre-treated oil-in-water emulsion comprising: (i) an aqueous phase containing water; and (ii) a pre-treated oil phase containing at least one reactive condensation-curable film-forming amino-silicone pre-polymer that, subsequent to condensation curing optionally in presence of additional reactants, forms an amino-silicone coat. The pre-treated reactive oil phase includes at least one pre-treated reactant or pre-treated pre-polymer. An aqueous dispersion containing particles of a hydrophilic polymeric material is then applied to the amino-silicone coat, so as to form a polymeric layer thereon. At least one of the oil-in-water emulsion forming a first coat and of the aqueous dispersion forming a second coat may further contain a plurality of sub-micronic pigment particles dispersed therein. Suitable compositions and kits including the same are also disclosed, as well as fibers coated thereby.

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.

A textile printing ink including polymer particles, contains: first polymer particles; second polymer particles having a weight average molecular weight different from a weight average molecular weight of the first polymer particles; and a binding aid that crosslinks the polymer particles, on a surface, inside, or outside of the first polymer particles and the second polymer particles, wherein when a weight average molecular weight of a polymer contained in the first polymer particles is denoted by HMw.sub.1 and a weight average molecular weight of a polymer contained in the second polymer particles is denoted by LMw.sub.2, a ratio (LMw.sub.2/HMw.sub.1) of the weight average molecular weight of the polymer of the second polymer particles to the weight average molecular weight of the polymer of the first polymer particles is in a range of 0.01 to 0.20.

An example of a multi-fluid kit includes a pretreatment fluid, a fixer fluid, and a white inkjet ink. The pretreatment fluid includes anionically modified cellulose nanocrystals and a first aqueous vehicle. In some examples, the fixer fluid includes an azetidinium-containing polyamine and a second aqueous vehicle. The multi-fluid kit is suitable for use in inkjet textile printing.

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.

A print method includes applying a first processing fluid comprising water and a lubricant to a fabric, applying a second processing fluid comprising water and a flocculant to the fabric, and applying an ink to the region of the fabric where the first processing fluid and the second processing fluid have been applied.

A multi-fluid kit for textile printing includes an inkjet ink and a fixer fluid. The inkjet ink includes a self-crosslinked polyurethane binder particle including a polyurethane polymer with a polymerized carboxylate-based diol and a polymerized sulfonated diamine, a pigment, and an ink aqueous vehicle; and a fixer fluid includes an azetidinium-containing polyamine, and a fixer aqueous vehicle.

The invention generally relates to fabric dyeing, such as fabric dyeing using indigo or sulphur dyes. A process is provided which provides a dyed yarn having reduced dye penetration and a white core. The process involves modification of existing sulfur dye ranges to more efficiently and in an environmentally improved method produce dyed fabrics. The modification involves one or more of i) using of a barrier compound to subsequent dye applications; ii) performing a scouring stage without a caustic agent; iii) bypassing scouring and/or scour rising; iv) using sodium bicarbonate to control the pH of dye tanks; v) reducing the dye concentration and increasing the number of dye vats; and vi) adding a sizing stage to the dye range. The invention also is directed to yarns dyed on dye ranges through use of the process, and fabrics formed from the dyed yarns.

The invention belongs to the technical field of waste cloth recovering and reusing, and particularly relates to waste-cloth-containing recovered fiber coating slurry and coating, and a preparation method thereof. 0.5-8 parts by weight of recovered fiber of waste cloth, 95-110 parts by weight of waterborne polyurethane, and 4-6 parts by weight of curing agent are prepared into recovered fiber coating slurry. The recovered fiber coating slurry is printed on a base cloth or a base plate, and dried to obtain a recovered fiber coating having a thickness of 0.1-1.0 mm. According to the technical solution provided by the invention, the field of physical method recycling of waste cloth is expanded to coating. Because the particle size of recovered fiber of the waste cloth is fine, the recovered fiber coating obtained by mixing waterborne polyurethane with a curing agent in a proper proportion has excellent abrasion resistance and mechanical properties.

A dispersion device configured to disperse a coloring material to a cloth substrate, comprising a hollow housing that contains the coloring material therein, the hollow housing being configured to fracture upon application of a force to the housing and disperse the coloring material to the cloth substrate to color the cloth substrate.
