Transferring printing is to point to imprint via turning the printing process that paper changes dye fabric to go up. It is the sublimate character according to a few dispersive dye, choose the dispersive dye in sublimate of 150~230 ° C, mix its and oar makings make " lubricious Chinese ink " , ask according to different blueprint proposal again, will " lubricious Chinese ink " presswork to transfer paper to go up (this is a kind of tailor-made paper, friend says to transfer paper) , will imprint next the move paper that has decorative pattern pattern and fabric are contacted closely, below the circumstance that dominates constant temperature, pressure and time, dye arrives from the move on printing paper on fabric, through diffusing action enters fabric interior, achieve chromatic goal thereby.

Move printing has sublimate law, migration law, melt law and printing ink layer to come off a few kinds of methods such as the law. Mature most with printing of sublimate law move among them.

1. Sublimate law

This is a kind of the most commonly used method, the raising of things to a higher level that uses dispersive dye is characteristic, the dispersive dye that use element quantity is 0.2~2 micron for diameter of 250~400, grain and water-solubility carrier (like algal acid natrium) or carrier of mellow dissolve sex (be like second radical cellulose) , colophony of oily dissolve sex makes printing ink, 20~30 second is handled on the move printing machine of 200~230 ° C, decentralize dye move is originallying to the synthetic fibre such as polyester fibber. Sublimate law experiences 3 processes commonly: Before transferring process happening, all dye imprints in paper in film, be by the dye chroma in printed fabric and empty air gap 0, the size of empty air gap depends on the structure of fabric, gauze is raised and transfer pressure; In changing a course, when paper reachs move temperature, dye begins to volatilize or sublimate, form chroma to volatilize between paper and fiber, when be achieved to transfer temperature by printed fabric, dye adsorption began in fiber surface, till reach fair saturation value. Be being transferred to fibrous from paper as a result of dye undertake continuously, its adsorption rate depends on dye diffuses the rate of fiber interior. Diffuse to make dye can directional, often issue a side vacuumize in the sole of the content that be caught, make dye is achieved directional diffuse move; After changing a course, after the content that be caught is chromatic, paper dye content drops, dye of partial the rest is migratory the interior to paper, dye quantity of remain depends on the evaporate steam pressure of dye, dye expects to the oar or transfer the ply of the affinity of paper and printing film. Sublimate law does not need to pass wet process commonly, but managing the sources of energy and the negative charge that reduce sewage disposal.
