A fabric treatment agent that is used in textile printing with a sublimable color material includes a color-material scavenging compound having an Rf value of 0.7 or less according to paper chromatography performed under following conditions. In Procedure 1, cellulose filter paper is impregnated with a 10% solution of the color-material scavenging compound and then dried to prepare a carrier. In Procedure 2, a 0.1% solution of a sublimable color material in tetrahydrofuran is spotted on the carrier and then dried to prepare a development sample. In Procedure 3, the development sample is developed using acetonitrile as a solvent for 3 minutes at 25 C. In Procedure 4, the Rf value is calculated by a following formula: $Rf=\frac{\left(\mathrm{distance}\mathrm{travelled}\mathrm{by}\mathrm{the}\mathrm{sublimable}\mathrm{color}\mathrm{material}\right)}{\left(\mathrm{distance}\mathrm{travelled}\mathrm{by}\mathrm{acetonitrile}\right)}.$

A welding process may be configured to convert a substrate into a welded substrate by applying a process solvent to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may be configured as an ionic-liquid based solvent and the welded substrate may be a congealed network after the process solvent has been adequately swollen and/or mobilized the substrate. A welding process may be configured such that individual fibers of a substrate are not fully dissolved such that material in the fiber core may be left in the native state by controlling process variables. The welding process fibers may have a tenacity 10% or 20% greater or a diameter 25% less than that of a cellulosic-based yarn substrate.

An aqueous inkjet ink composition for textile printing contains A to E: A. a pigment; B1. a solvent with a boiling point of 280 C. or higher; B2. as solvents with a boiling point of 200 C. or lower, a glycol ether accounting for 0.1 to 6.0% by mass, and a dihydric alcohol, wherein the ratio by mass of the solvent B1 and solvent B2, or B1/B2, is 0.3 to 3.0; C. a polyurethane resin-based water-dispersible resin; D. a surfactant; and E. a blocked isocyanate crosslinking agent accounting for 0.1 to 5.0% by mass. The aqueous inkjet ink composition is intended to have appropriate discharge property, which is capable of demonstrating superior image density and higher levels of washing fastness even when printed on cotton or polyester cloth, etc.

A method of color-dyeing a lens for goggles and glasses, whereby the lens includes a polycarbonate substrate, the method including the steps of: providing a liquid mixture of components including at least one dye or pigment, suitable for color-dyeing polycarbonate and a dispersion medium, whereby the at least one dye or pigment is dispersed as colloids in the dispersion medium; immersing the substrate into the mixture such that the at least one dye or pigment is impregnated into the substrate; and withdrawing the substrate from the mixture. The method is characterized in that the dispersion medium includes a solvent for dissolving the at least one dye or pigment, whereby the solvent includes at least one member selected from the group including an organic alcohol, in particular an aromatic alcohol, in particular benzylic alcohol; a butyl acetate, and a methacrylate ester, in particular methyl methacrylate.

A ink set for textile printing comprising an inkjet ink and an overcoat layer-forming liquid, in which the volume average particle diameter of wax particles contained in the overcoat layer-forming liquid is twice or more the volume average particle diameter of fixing resin particles contained in the inkjet ink. The fixing resin particle may have a glass transition temperature of 35 C. or lower.
