Characteristics and matters needing attention of heat transfer printing ink
Heat transfer printing ink is mainly composed of dyes, connectors, solvents and a small number of auxiliary additives.
1. Heat sublimation ink dyes need to have good sublimation transfer and permeability, transfer to the fabric after reaching a certain degree of rigidity, generally choose small molecular weight, disperse temperature of disperse dyes, transfer printing dyes commonly used anthraquinone dyes, azo dyes and cationic dyes. Common connectors have low viscosity ethyl cellulose, ethyl hydroxyethyl cellulose, etc., connector requirements and dye affinity is small, can easily release dye gas under the action of high temperature. Commonly used solvents include turpentine, terpentine alcohol, high-boiling alkanol, fibrinolytic agent and so on. A small number of auxiliary additives to improve the performance of the ink itself, such as drying, viscosity, etc. Hot melt inks generally require that dyes can be under the action of high temperature uniform dispersion in the molten state of the adhesive layer and a good color on the fabric.
2. Heat transfer ink advantages and disadvantages mainly in the following points.
Heat transfer ink anti rub dirty performance is closely related to the printing ink after the fast drying performance, if the fabric of ink text and text after printing can not quickly form a fixed state, it is easy to have contact with dirty, affect the transfer effect.
In the process of producing heat transfer printing technology, how to choose the most suitable heat transfer printing ink can be distinguished by its certain characteristics and matters needing attention. But even if engaged in this process production, do not blindly think about reducing costs. We must be able to achieve the standard process criteria, and then can not affect the process standards under the premise of rational cost compression.

2. Heat transfer ink advantages and disadvantages mainly in the following points.
(1) good flow performance
The flow performance of heat transfer printing ink refers to the flow performance of printing ink on the surface of paper-based material coating and the formation of printing ink layer uniform, smooth degree, flow performance covers viscosity, adhesion, yield value and thixotropy and other ink properties.(2) good scrubbing performance
(3) good color rendering performance and resistance
Color performance refers to the sublimation ink can be accurate and realistic reduction of the original color and level, there is no slant, color mixing phenomenon. Resistance refers to the heat transfer process after the completion of the fabric printing in the use of the process, such as light, water, acid, alkali and other external factors, can maintain its color stability for a long time.In the process of producing heat transfer printing technology, how to choose the most suitable heat transfer printing ink can be distinguished by its certain characteristics and matters needing attention. But even if engaged in this process production, do not blindly think about reducing costs.
