Description

Acid dye ink for cold transfer printing, configuration method and application method thereof

The invention relates to a printing dye ink used in the textile industry, in particular to a preparation method using an acid dye ink and a method thereof applied to cold transfer printing.

According to Japan's "Processing Technology" 1972 "Transfer Printing" album, transfer printing was invented by researchers of Prouvost Masurel in France before the 1950s, when the process was actually a sublimation transfer printing. Transfer printing is a method of printing a suitable dye ink by printing, printing a pattern or text to be printed on a special carrier, printing a transfer printing carrier; and printing the transfer printing carrier with a dye. One side is in close contact with the printed fabric, and the dye is sublimated or the dye ink is transferred from the carrier by a transfer printing machine under the action of transfer device heating and pressure (sublimation method) or solvent and pressure (wet method) and for a certain period of time. Dissolve and peel off, transfer the pattern or text of the transfer printing carrier onto the fabric to complete the printing task. The acid dye is a dye which can be dyed in an acidic (or neutral) medium, and contains a water-soluble group such as a sulfonic acid or a carboxylic acid in the molecule. The chemical structure of the nylon fiber is polyamine, and the molecule is mainly composed of three parts, that is, a methylene bond constituting a hydrophobic portion in the molecule, a hydrophilic guanamine group and a chain terminal amino group and a carboxyl group. Therefore, it can be dyed with a hydrophilic acid dye. In addition to direct printing, in recent years, in order to improve the quality of printing, there has also been a transfer printing technology of acid dyes. For example, the patent application number is CN200710025330.6 "Acid Dye Gravure Ink and Preparation Method thereof discloses an acid dye gravure ink printed on PET and BOPP plastic film, which is suitable for wet transfer printing. However, the organic solvent accounts for more than 50% of the formulation, which is a solvent-based ink.
