Embodiment 1

[0032] Example 1: Formulation of acid mordant and neutral dye digital printing ink

[0033] Take the corresponding acid mordant and neutral dye from the market, add an appropriate amount of dimethylformamide solvent, remove the insoluble matter with filter paper or filter cloth, and then evaporate the organic solvent to obtain the refined dye. Take the above-refined C.I. Medium Yellow 10 (Acid Medium Yellow 2G) 0.1-0.2kg; C.I. Medium Red 3 (Acid Medium Red SW) 0.1-0.2kg; C.I. Medium Black 11 (Acid Medium Black T) 0.1-0.2kg and Metal-free C.I. Acid Blue 183 (neutral brilliant blue S-5GL) 0.1-0.2kg, each of which is added to wetting agent polyethylene glycol 2kg; preservative sorbic acid 0.05kg, put into a container, at room temperature Add 5-10kg of water to dissolve and prepare dye solutions of four colors. The above solution is filtered again with a filter cloth to remove insolubles and impurities to obtain an acid mordant digital printing ink.

Embodiment 2

[0034] Example 2: Silk and wool pre-mordant treatment and digital printing

[0035] The digital printing ink of the above-mentioned embodiment 1 is taken and poured into the four ink cartridges of the digital printing machine for use. First, pre-mordant the wool and silk: (1) Take 0.05-0.1 kg of potassium aluminum sulfate, 0.1 kg of cresol, and then take carboxymethyl cellulose pulp. For example, take 10 kg of silk or wool as an example, use carboxymethyl cellulose Cellulose 0.3 ~ 0.4kg. Mix the above components and add 10-15kg of deionized water to control the spraying liquid with PH=3-5. (2) Hold up the edge of the silk or wool fabric for even spraying operation, then (3) dry it under mild temperature conditions, iron it, and set aside.

[0036] The second step of printing: The pre-mordant treated fabric is passed through a digital printing machine, and is printed with a digital printer ENCAD Nova Jet700 or ENCADCroma 24 thermal foaming digital printer under the program of...

Abstract

The digital printing ink dye is refined acid medium dye and neutral dye and includes C.I. medium yellow, C.I. medium red, C.I. medium black and neutral bright blue S-GL. The ink comprises dye 0.5-5 wt%, wetter 5-50 wt%, solubilizer 0-10 wt% and preservative 0-2 wt% except water. The dye refining process includes dissolving dye in organic solvent, filtering to eliminate impurity and final removing organic solvent. The digital printing process includes the steps of: pre-mordanting fabric with aluminum salt; printing in digitally printing machine; and post-treating fabric. The present invention has the advantages of low cost, stable digital printing ink, and high color fastness of printed wool and silk.

Description

technical field [0001] The invention relates to a digital printing ink, a dye refining method and a digital printing method, in particular, acid mordant dyes and metal-free neutral dyes are selected and refined, and made into textile digital printing ink, and a digital printing method is adopted. Aluminium salt pre-mordant printing on textiles. Background technique [0002] In recent years, textile printing has adopted a digital printing technology. Because it avoids the need to make a corresponding screen for each pattern in printing and dyeing, it takes a long time and costs a lot. Only mass printing is possible. The disadvantage of reducing costs. The use of digital printing (formerly known as inkjet printing), without plate making, changing patterns and fast printing speed, is suitable for small batches, multi-patterns, individualization, fast delivery and high quality, and is highly valued by the printing and dyeing industry. Such as the method of digital printing and...
