A textile material comprises a plurality of yarns, the yarns containing an intimate blend of dyed polyphenylene sulfide fibers and aramid fibers. The dyed polyphenylene sulfide fibers comprising a disperse dye that is distributed substantially evenly across the cross-sectional area of the fibers. A method for dyeing textile materials containing polyphenylene sulfide fibers comprises the steps of (a) providing a plurality of polyphenylene sulfide fibers and aramid fibers; (b) spinning the blend of fibers into a plurality of yarns; (c) forming the yarns into a textile material; (d) subjecting the textile material to a polyphenylene sulfide dyeing process.

A method for recycling dye from a dyed textile, the method comprising providing a textile coloured with a dye; adding the textile to a bath comprising a solution of ionic liquid, thereby causing the dye to strip from the textile and to disperse within said solution.

A fabric has enhanced response characteristics for laser finishing. The fabric can be denim for denim apparel such as jeans. Software and lasers are used to finish apparel made of the fabric to produce a desired wear or distressing pattern or other design. The fabric allows for relatively fast color change in response to the laser, color changes in hue from indigo blue to white, many grayscale levels, and maintains strength and stretch properties. A method used to make the fabric includes spinning, dyeing, and weaving yarns in such a way to obtain the desired enhanced response characteristics for laser finishing.

A filter for capturing dyestuff is provided. The filter includes a housing defining an inlet. The housing further includes an outlet spaced from the inlet. The housing further includes a cartridge in fluid communication with the inlet and the outlet. The inlet is adapted to receive effluent including dyestuff and the outlet is adapted to release the effluent. The filter further includes a substrate disposed within the cartridge. The substrate includes an active material. The active material has an affinity for the dyestuff. The dyestuff is present in the effluent at the inlet in a first amount and not present in the effluent at the outlet or present in a second amount with the second amount less than the first amount. The filter is composed of a textile composition made fiber or fabric which can be recycled by mulching back into a dyed fiber upcycling the normally wasted dyestuff, to now be reused in an upcycled dyed textile production. The filter with its reusable cartridge, the substrate which bonds and upcycles waste dyestuff operates in a linear or preferable circular economy.

Provided are a textile printing ink set including a pretreatment liquid including a cationic compound having a molecular weight per cationic valence of 150 to 220, and an ink composition including a water-insoluble dye, a dispersing agent, and water, wherein the dispersing agent is at least one selected from the group consisting of a urethane resin, a urea resin, and a urethane-urea resin; and a textile printing method.

A pigment printing ink jet ink composition includes a pigment, a resin particle, a sulfonate-based anionic surfactant, and water.

A sublimation printing method on cotton and/or viscose is described comprising the steps of: preparing a piece of laminar substrate, applying (for example) microcapsules onto a side of said piece of laminar substrate, wherein said microcapsules comprise a core of polyester and/or polyamide and/or polyethylene and a shell of cellulose and/or starch, ink-jet printing onto said side of said piece of laminar substrate using sublimation ink, preparing a piece of fabric containing a high amount of cotton and/or viscose, approaching said piece of laminar substrate and said piece of fabric, pressing and heating, and separating said piece of laminar substrate from said piece of fabric; a fabric ready for sublimation printing is obtained if the step of ink-jet printing is not performed.
