The present disclosure provides dye compounds for use in dyeing textiles.

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.

Methods for processing denim are provided. An initial fabric is abraded by passing the initial fabric through an abrader at a first predetermined speed, thereby obtaining a pre-washed fabric with an abraded texture. The abrader comprises one or more sanding boards, where each respective sanding board has a respective diamond surface that contacts the initial fabric while spinning about a respective axis at the respective center of the respective sanding board during the abrading. The pre-washed fabric is then washed with an ozone composition, thereby obtaining an ozone washed fabric.

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.

Methods and systems are provided for treating a textile substrate. In one example, a method of treating a textile substrate comprises jetting a plurality of treatment compositions from an inkjet printer on to only a treatment area of the textile substrate without being jetted outside of the treatment area, the plurality of jetted treatment compositions each forming a treatment layer over the treatment area, wherein outside of the treatment area the textile substrate is bare of the treatment layers. Jetting the plurality of the treatment compositions includes jetting a pretreatment composition adjacently over the textile substrate, jetting an ink composition over the textile substrate, and jetting a topcoat composition over the textile substrate, and adjusting a composition of the plurality of treatment compositions jetted from the inkjet printer based on a hydrophobicity of the textile substrate.

A printing treatment liquid composition which is to be adhered to a cloth, includes: a compound including a polyvalent carbodiimide group which has a carbodiimide group equivalent of 500 g/mol or less; and an aromatic carboxylic acid and/or its salt. According to the printing treatment liquid composition described above, a content of the compound including a polyvalent carbodiimide group with respect to a total mass of the treatment liquid composition is 1.0 to 35.0 percent by mass, a content of the aromatic carboxylic acid and/or its salt with respect to the total mass of the treatment liquid composition is 0.1 to 30.0 percent by mass, and the cloth contains fibers having hydroxy groups.

A fluid set for textile printing can include an ink composition including an ink vehicle, pigment, and from 1 wt % to 15 wt % epoxide-reactive polymer. The fluid set can also include a fixer fluid including a fixer vehicle, and from 0.5 wt % to 12 wt % of a multiepoxide-containing resin.
