A textile dyeing process is described for dyeing a textile material, product or article consisting of animal fibers, comprising the steps of dipping said textile material, product or article into a dyeing bath comprising at least one detergent substance, a wetting substance, a leveling substance and an acidity regulator; adding to the dyeing bath a coloring substance approved for food use; subjecting the dyed textile material, product or article to washes; and finally subjecting the dyed textile material, product or article to a color fixing treatment.

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.
