The present invention aims to provide an ink ejection stabilizer that can impart high ejection stability, for example, to an ink such as an ink-jet printing ink. The present invention relates to an ink ejection stabilizer including a polymer (A) that has, in a Kratky plot of a scattering profile determined by a small-angle X-ray scattering method using synchrotron radiation, at least one local minimum in the range where a scattering vector q is 0 nm.sup.1 to 2 nm.sup.1. An aqueous solution of the polymer (A) (polymer (A) concentration: 20 mass %) has a parallel light transmittance of 85% or more.

The present invention provides a water-based ink comprising nanopigment micelles, said nanopigment micelles comprising a pigment particle and a polymeric dispersing agent around said pigment particle, whereby said pigment particles have an average particle size between 100 nm and 250 nm. The invention also relates to a printed textile and a dyeing and printing process using said water-based ink.

Provided is a method for decolorizing a polyester, the method including exposing adding a decoloring agent to the polyester and then contacting the polyester with superheated water vapor.

An ink jet textile printing penetrant includes a water-soluble organic solvent; a surfactant; and one type or two or more types selected from the group consisting of a chelating agent and an aromatic compound.

A textile material comprises a plurality of yarns, wherein the yarns contain an intimate blend of dyed polyphenylene sulfide fibers and cellulosic fibers. The dyed polyphenylene sulfide fibers comprise 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 textile material comprising yarns which contain an intimate blend of polyphenylene sulfide fibers and cellulosic fibers, (b) providing a dye liquor comprising a liquid medium and a disperse dye, (c) applying the dye liquor to the textile material, (d) heating the textile material under ambient atmosphere to a temperature sufficient to evaporate substantially all of the liquid medium from the textile material, and (e) heating the textile material under ambient atmosphere to a temperature of about 180? C. or more to fix the disperse dye to the polyphenylene sulfide fibers.

Provided herein is a digital ink composition containing a minimal amount of volatile organic compounds (VOC), and a method for reducing VOC emission during digital printing of an image on a fabric.

An example of a white inkjet ink includes: a non-self-dispersed white pigment; from about 0.005 wt % to about 1 wt %, based on a total weight of the white inkjet ink, of an anionic copolymer dispersant having a weight average molecular weight (Mw) ranging from about 125,000 g/mol to about 30,000,000 g/mol; a polymeric binder; and an aqueous vehicle. The white inkjet ink may be used in a textile printing kit.

An ink jet textile printing penetrant includes a water-soluble organic solvent; a surfactant; and one type or two or more types selected from the group consisting of a chelating agent and an aromatic compound.

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.
