Sublimation is the transition of a solid substance directly from the solid to the gas phase without passing through the liquid phase through heat treatment. (E.g. burning of coal to smoke …). Chemical reactions in sublimation printing in other words transfer printing with digital printing dye is formed in this way. Sublimation dye particles present in solid form as micro-particles in the sublimation dye. Sublimation dye transferred onto the transfer printing paper by means of digital printing machines.
When transfer printing papers, placed on the desired surface for printing, pressed below pre-defined heat by using transfer printing machines, solid sublimation dye particles in the form of micro-particles on the transfer paper turns into a gas form (imprinted fabric, locks into the paint on transfer printing paper, thus printing job is done.) If there are polyester molecules exist in the environment, dye turned into gas form paints polyester molecules. If there is no polyester on printing surface, paint in gas form mixes with the air. As you will understand here, polyester – polyamide molecules must exist on products to be printed using sublimation transfer printing method. Otherwise no transfer can be achieved.
Generally, polyester and polyamide (lycra, nylon) are used for printing on fabric in sport wears and outwears. Mixed synthetic (min. 60% synthetic fibers) are used for printing on fabric in sport wears and outwears. In production of sportive materials like ski boards, windsurfing boards, water skiing equipment materials, polyester having plastic raw materials are used for printing. Surfaces like wood, ceramics, glass coated with polyester raw materials and polyamide raw materials can be used for printing.
Usage Areas: For printing fabrics used for flags, sport textiles, home textiles, and advertising industry, and for printing polyester coated metal, plastic, wood, ceramic and similar products.
