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.

Described herein are compositions useful for infusing color into nonwoven polyester containing product and methods to do so. Such compositions and methods comprise use of a color infusion composition comprising an antimigrant polymer; pigment; ammonium polyphosphate; and an anionic surfactant comprising phosphate. In certain embodiments, thermoplastic polymer having a glass transition temperature (Tg) of 93.0° C. or less is used to enhance color infusion.

An ink contains an aqueous medium, coloring particles dispersing in the aqueous medium, and a cross-linking agent having a carbodiimide group. The coloring particles contain a specific vinyl resin and a specific salt compound containing a dye. The specific vinyl resin includes a specific repeating unit derived from a specific monomer having a carboxy group. The specific vinyl resin has an acid value of at least 50 mg KOH/g and no greater than 150 mg KOH/g. The specific vinyl resin has a glass transition point of at least 50° C. and no higher than 80° C. The ink does not contain a free resin dispersing or dissolving in the aqueous medium or has a percentage content of the free resin of greater than 0.00% by mass and no greater than 0.50% by mass.

The present disclosure provides an ink fluid set containing an aqueous pre-treatment composition, a clear ink, and colored aqueous inkjet inks. This ink fluid set is particularly suitable for printing on polyester, cotton, and blends of cotton and synthetic textiles.

An ink jet composition according to the present disclosure contains a flameproofing agent and resin particles. The resin particles are preferably urethanic resin particles. It is preferable that a urethanic resin making up the urethanic resin particles is a urethanic resin containing a crosslinking group and the crosslinking group is one or more selected from the group consisting of a blocked isocyanate group and a silanol group. The urethanic resin making up the urethanic resin particles preferably has a polycarbonate skeleton.

A white ink jet ink composition according to the present disclosure includes hollow resin particles, resin particles, and water. The hollow resin particles have a glass transition temperature of 120° C. or more, the resin particles are composed of an acrylic resin or a urethane resin, and the content of the resin particles is 5% by mass or more relative to the total mass of the ink composition.

Provided are compositions and processes formulated and practiced to reduce the friction-coefficient of the printed area and also of the non-printed areas around the image, wherein the compositions are formulated for use by wet-on-wet techniques in-line of the pre-curing printing process, without pretreating the fabric for softness and smoothness prior to the printing process. The compositions comprise at least 15% by weight of a friction-coefficient reduction agent and having a pH lower than 6.5 so as to effect upon contact immobilization of an ink composition that is being digitally applied on the substrate.

A fabric processing method of the present disclosure includes an attaching step of attaching a carboxylic anhydride to a fabric containing cellulose, and an esterification step of esterifying a hydroxyl group of the cellulose, in which, in the esterification step, the carboxylic acid is introduced into the cellulose through an ester bond. A molecular weight of the carboxylic anhydride preferably is 1000 or less.

A printing method contains applying a processing fluid to a fabric and applying an ink to the fabric to which the processing fluid has been applied, wherein the ink contains a pigment, a resin having a cross-linkable functional group, a pH regulator, and at least one member selected from a block isocyanate compound, a carbodiimide compound, and a polymer having an oxazoline group.
