A sprayable and hygroscopic ink for a digital printing process on a fabric includes 3.0 parts by weight to 6.0 parts by weight of a colorant, 0.5 parts by weight to 2.0 parts by weight of a hygroscopic agent, 0.5 parts by weight to 1.0 part by weight of a surfactant, and a balance of a solvent, in which a pH value of the hygroscopic agent is between 6.0 and 8.5 at 25° C., and a particle diameter D90 of the sprayable and hygroscopic ink is between 180 nm and 220 nm.

A whitening composition for fabric, in particular, unbleached cellulosic fiber-containing fabric. The composition includes a blue dye, a violet dye; and, optionally, a thickening agent; wherein the composition is free of bleaching agents and optical brighteners. A method of whitening a fabric using whitening compositions is also disclosed.

There is provided a treatment agent applicable to a recording surface of a recording medium which is recording paper or fabric. The treatment agent contains: a non-cationic sizing agent; and at least one cationic substance which is selected from the group consisting of: a cationic polymer capable of forming a flexible film in a case that the cationic polymer is dried, a cationic surfactant, a polyvalent metal salt and a polyvalent metal ion.

The present invention relates to a process wherein one or more dye precursors, e.g., indole, are provided to a textile and converted by one or more enzymes, e.g., an oxidizing enzyme, to provide the textile with a dye, e.g. indigo. At least the oxidizing enzyme is a hybrid enzyme including a binding domain that is suitable to bind the enzyme to the textile and/or increase the affinity of the enzyme for the textile, in particular, a cellulose binding domain (CBD).
