An ink jet textile printing ink containing: water; a coloring material; a polymer X which is a water-soluble polymer with a weight-average molecular weight of 6,000 to 35,000, including at least one selected from the group consisting of a structural unit derived from alkylene glycol, a structural unit derived from vinyl alcohol, and the like; a solvent A which is a water-soluble organic solvent with a molecular weight of 160 or less, in which a ratio of the solvent A in all water-soluble organic solvents contained is 70 mass % or greater, a content of the polymer X is greater than 0.8 mass % and 7.0 mass % or less, and a content mass ratio [solvent A/polymer X] is 7.0 to 50.

The present disclosure describes phosphonium-containing polyurethane compositions, coating compositions, and coated fabric media. In one example, a phosphonium-containing polyurethane composition can include an aqueous liquid vehicle and polyurethane particles. The polyurethane particles can include a polyurethane polymer devoid of end cap groups. The polyurethane polymer can include a polyurethane backbone having a polymerized diamine chain extender forming a portion of the backbone. The polyurethane polymer can also include side chain groups along the polyurethane backbone. The side chain groups can collectively include aliphatic phosphonium salts and polyalkylene oxide groups.

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 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 process for preparing a natural fiber fabric for finishing the fabric with a botanical dye or printing content on the fabric with a botanical dye includes washing the natural fiber fabric in a washing solution comprising approximately equal parts washing soda and baking soda dissolved in water and rinsing the washed natural fiber fabric. The process also includes pre-treating the washed natural fiber fabric with a pre-treating solution comprising a bio enzyme in water and rinsing the pre-treated natural fiber fabric. After pre-treating, a pH of the washed and pre-treated the fabric load may be neutralized with a solution comprising vinegar in water.

The pretreatment liquid of the present invention is applicable for a fabric to be used for inkjet textile printing, and the pretreatment liquid contains a block copolymer including a hydrophobic block derived from a hydrophobic resin having an SP value of less than 11 and a hydrophilic block derived from a hydrophilic resin having an SP value of 11 or more, with the difference between the SP values of the hydrophobic resin and the hydrophilic resin of 1.0 or more; and water.

An inkset and a process for direct inkjet printing color images on dyed synthetic fabrics is provided herewith, based on forming an image on the fabric in the form of a well-adhered crosslinked film, using an acid-immobilized ink composition, while avoiding dye migration from the fabric to the image in the process of curing the film, using a low-temperature curing crosslinking agent and curing the image at a temperature lower than 120±5° C.
