A pretreatment liquid for inkjet textile printing is disclosed that includes water and a cellulose-based polymer having a weight average molecular weight of at least 50,000. A method for producing a printed textile item and an ink set for inkjet textile printing are also disclosed.

A dye-releasing product for dyeing of or for refreshing of dyeing in textile materials is provided. The dye-releasing product includes a flat, cloth-like carrier material, and at least one coating applied onto the carrier material. At least one indigoid dye in its oxidized form is encompassed by the coating. The coating contains at least one binding agent for the at least one indigoid dye such that the at least one indigoid dye is released in an aqueous solution with a temperature equal to or greater than 20 C. that is, the coating is soluble, at least in part from the flat, cloth-like carrier material, which is added to the textile material to be dyed or whose dyeing is to be refreshed in a washing process.
