Embodiment 1

[0017] Embodiment 1 Acidic digital ink-jet ink for silk fabrics.

[0018] Acidic digital ink-jet ink formula for silk fabrics, its content by weight percentage of each component is:

[0019] Refined acid dye 5-12%;

[0020] Triethylene glycol monomethyl ether 16%;

[0021] Glycerin 25%;

[0022] Deionized water was adjusted to 100%.

[0023] The amount of refined dyes depends on the color of the pattern. The refined acid dyes can be composed of C.I. Acid Yellow 49, C.I. Acid Red 35, C.I. Acid Blue 185 and C.I. Acid Black 24 to form a four-color ink. The surface tension is 25-28mN / m, and the viscosity is 5-9mPs·s.

[0024] The production process of acidic digital inkjet ink is as follows: add N,N-dimethylformamide to commercially available acid dyes to completely dissolve the dyes, filter with a 0.45 μm filter membrane, add acetone to the resulting filtrate, and the dyes will precipitate. Filter with a 0.45μm filter membrane, collect the precipitated dye filter cake, and d...

Embodiment 2

[0026] Example 2 Acid digital inkjet ink for wool fabric.

[0027] Acidic digital inkjet ink formula for wool fabric, its content by weight percentage of each component is:

[0028] Refined acid dye 5-12%;

[0029] Triethylene glycol monomethyl ether 20%;

[0030] Glycerin 22%;

[0031] Deionized water was adjusted to 100%.

[0032] The amount of refined dyes depends on the color of the pattern. The refined acid dyes can be composed of C.I. Acid Yellow 110, C.I. Acid Red 27, C.I. Acid Blue 90 and C.I. Acid Black 72 to form a four-color ink. The surface tension is 25-28mN / m, and the viscosity is 5-9mPs·s.

[0033] The production process of acidic digital inkjet ink is as follows: add N,N-dimethylformamide to commercially available acid dyes to completely dissolve the dyes, filter with a 0.45 μm filter membrane, add acetone to the resulting filtrate, and the dyes will precipitate. Filter with a 0.45μm filter membrane, collect the precipitated dye filter cake, and dry the re...

Embodiment 3

[0035] Example 3 Nylon fabric with acidic digital inkjet ink.

[0036] Acidic digital inkjet ink formula for nylon fabric, its content by weight percentage of each component is:

[0037] Refined acid dye 5-12%;

[0038] Triethylene glycol monomethyl ether 18%;

[0039] Glycerin 20%;

[0040] Deionized water was adjusted to 100%.

[0041] The amount of refined dyes depends on the color of the pattern. The refined acid dyes can be composed of C.I. Acid Yellow 49, C.I. Acid Red 37, C.I. Acid Blue 62 and C.I. Acid Black 76 to form a four-color ink. The surface tension is 25-28mN / m, and the viscosity is 5-9mPs·s.

[0042] The production process of acidic digital inkjet ink is as follows: add N,N-dimethylformamide to commercially available acid dyes to completely dissolve the dyes, filter with a 0.45 μm filter membrane, add acetone to the resulting filtrate, and the dyes will precipitate. Filter with a 0.45μm filter membrane, collect the precipitated dye filter cake, and dry th...

Abstract

The invention relates to a manufacturing process for acidic digital ink-jet ink used for digital inkjet printing of fabrics such as silk, wool, nylon, etc. The ink is composed of a refined acidic dye, triglycol monomethyl ether, glycerin and deionized water. A printed fabric finished product is obtained by the steps of pretreating the fabric with a pretreatment liquid, drying the fabric, printing the acidic digital ink-jet ink on the fabric according to designed patterns via a piezoelectric digital inkjet printing machine, steaming for fixing colors, and finally washing with water to shape the patterns. The acidic dye ink can be used for digital in-jet printing of fiber fabrics such as silk, wool, nylon and the like. The ink has low manufacturing cost, full chromatograph, good adaptability and good ink stability, does not block a spraying nozzle, and has significant popularization value.

Description

technical field [0001] The invention relates to the production of digital ink-jet printing ink in the textile printing and dyeing industry, in particular to a process for producing acid dye water-soluble digital ink-jet ink. Background technique [0002] Inkjet technology was first applied in the 1930s, and its initial development was relatively slow. It did not begin to develop rapidly until the 1960s, and the technology developed more maturely in the 1980s. With the rapid development of computer technology, inkjet printing technology and inkjet printing technology are also rapidly popularized. In recent years, people have applied paper inkjet printing technology to textile printing, eliminating a series of processes such as color separation and net making in traditional printing, and adapting to the situation of short process, small batches and fast delivery, which has aroused the printing and dyeing industry. of great importance. Due to its shortcomings such as slow spe...
