Invisible fluorescent white dye transfer printing method of thermal sublimation cloth

Abstract

The invention relates to an invisible fluorescent white dye transfer printing method of thermal sublimation cloth. According to the method, a thermal transfer printing heating device, cloth, and transfer printing paper with a length equal to that of the cloth are adopted. The invisible fluorescent white dye transfer printing method of thermal sublimation cloth comprises following steps: the surface of the transfer printing paper is coated with a thermal sublimation dye layer, wherein, in the thermal sublimation dye layer, thiophenediylbis is taken as a disperse invisible fluorescent white dye;the cloth and the thermal sublimation dye layer of the transfer printing paper are laminated in a corresponding manner to obtain a whole body, the cloth and the transfer printing paper are guided andcontrolled to pass through a thermal transfer printing device, and the thermal transfer printing device is heated to a thermal transfer printing temperature, so that the dye in the thermal sublimation dye layer of the transfer printing paper is transferred onto the cloth through sublimatio and transfer printing.

Description

technical field [0001] The present invention relates to a method for transferring invisible fluorescent white dyes to dye sublimation fabrics, in particular to a dye sublimation transfer technology to transfer dyes with fluorescent white properties to the fabrics. Background technique [0002] Whether it is inkjet printing or traditional printing technology, four-color printing is used. First, the original is separated into four-color plates of cyan (C), magenta (M), yellow (Y), and black (K). Color synthesis is carried out during printing. The so-called color separation is based on the principle of subtractive color method, using the red (R) green (G) blue (B) three-color filter to selectively absorb the colored light of different wavelengths. characteristics, and decompose the original into three primary colors of yellow, magenta, and cyan, but according to the principle of subtractive color method, the aforementioned three primary colors cannot be mixed into white dye, wh...
