A process of sublimation printing on hide or leather, a laminar substrate to be used in such a sublimation printing process, hide or leather treated to be printable, as well as hide or leather printed by said process of sublimation printing, are described.

To provide a pretreatment liquid for inkjet textile printing, having excellent color development in the inkjet textile printing process, excellent color fastness to washing on printed fabrics, and little pretreatment trace residue. The solution therefor is a pretreatment liquid for inkjet textile printing containing 100 parts by mass of a cationic polymer (A), 5 parts by mass or more and less than 100 parts by mass of a (meth)acrylate-based vinyl copolymer (B), and 2 parts by mass or more and less than 30 parts by mass of a crosslinking agent (C), each being in solid content, and water, the liquid having a solid content by weight of 2 mass % or more and 30 mass % or less.

A process of sublimation printing on hide or leather, a laminar substrate to be used in such a sublimation printing process, hide or leather treated to be printable, as well as hide or leather printed by said process of sublimation printing, are described.

Procedure comprising a first phase of geometric transformation of fibreglass by pressure and temperature to the desired shape to follow with a second phase of application of pigments in different layers that are applied in a liquid manner with certain curing times, preferably a pressure is applied within a range from 3 bars to 7 bars, at a temperature comprised within a range from 120 C. to 140 C., for a time of about 15 to 20 minutes, where the subsequent phase of application of pigments is carried out in four phases obtaining in each phase a layer with a thickness of between 5 to 10 microns with intermediate curing times within a range from 70 minutes to 110 minutes. A fabric with a non-conductive carbon fibre appearance of special application on electrical circuits is achieved.
