Description

Textiles digit printing REACTIVE DYES ink-jet ink and production technology thereof

Technical field

The present invention relates to a kind of ink-jet ink and production method thereof, especially relate to a kind of textiles digit printing REACTIVE DYES ink-jet ink and production technology thereof.

Background technology

Ink-jet printedly used for many years in textile industry, this method can be saved the making of stamp half tone, thereby can save plenty of time and cost, especially for changeable style moulding situation, can clearly reach desired variation in shorter time.

Ink-jet ink is applied in the industrial textile, the stability of ink, COLOR FASTNESS, washing fastness and degree of hydrolysis all need to satisfy higher requirement, use ink mostly to be reactive dye ink, ACID DYES or DISPERSE DYES in the existing industrial textile, wherein the REACTIVE DYES pH value raises easily, hydrolysis or alcoholysis easily take place in water, thereby reduced the COLOR FASTNESS of printing in textiles, the general term of validity is no more than three months, expired its color fastness decreased, fugitive color, ink decomposes easily, can not long preservation, owing to contain impurity, block shower nozzle easily in addition more.

United States Patent (USP) discloses a kind of ink of printing in textiles for No. 5603756, it comprises at least a chemically-reactive dyes, a kind of polyalcohol and water, wherein this ink also comprises a kind of product by chemically-reactive dyes and polyol reaction, but because the ink of this printing in textiles does not use suitable composition, so its colouring dynamics and COLOR FASTNESS are not good.

United States Patent (USP) discloses a kind of ink No. 6015454, comprise at least a chemically-reactive dyes and 1,2-propylene glycol or N-methyl-2-pyrrolones, this patent has been improved the problem of colouring dynamics and COLOR FASTNESS, but, still remain to be improved for aspects such as long-time preservation, difficult infringement shower nozzles.

Summary of the invention

The objective of the invention is to the above deficiency at prior art, a kind of COLOR FASTNESS height, washing fastness height are provided, the storage time is long, is difficult for blocking the textiles digit printing REACTIVE DYES ink-jet ink of shower nozzle.

Another object of the present invention is to provide a kind of production technology of textiles digit printing REACTIVE DYES ink-jet ink.

For realizing above purpose, the present invention realizes by following scheme: a kind of textiles digit printing REACTIVE DYES ink-jet ink, its by weight hundred parts than composed of the following components:

Dyestuff 1-10%;

Humectant 10-15%;

Scale remover 1-5%;

Bactericide 0.2-1%;

PH value controlling agent 1-5%;

Bleeding agent 0.5-5%;

Its surplus is a deionized water.

Preferably described dyestuff is a REACTIVE DYES.

Preferably described humectant is at least a among ethylene glycol, diethylene glycol, glycerol, ethanol, the PEG.

Preferably described scale remover is at least a among isopropyl alcohol, 2-Pyrrolidone, the NMP.

Preferably described bactericide is D-7.

Preferably described pH value controlling agent is at least a in monoethanolamine, diethanol amine, triethanolamine, the oxyammonia.

Preferably described bleeding agent is at least a among NP-10, the NP-15.

Preferably described deionized water is for removing copper, iron, chromium, manganese metal ion and Cl ^-, SO ₄ ^2-After water.

A kind of production technology of textiles digit printing REACTIVE DYES ink-jet ink comprises step:

(A) dyestuff, humectant, scale remover, bactericide, pH value controlling agent, bleeding agent, deionized water are mixed at normal temperatures, fully stirred 0.5-1 hour, get mixed solution;

(B) mixed solution is left standstill slaking in 24-48 hour under temperature 50-70 ℃, get the slaking mixed solution;

(C) the slaking mixed solution through 1 micron, 0.5 micron, 0.22 micron membrane filtration, obtains end product successively.

The textiles digit printing REACTIVE DYES ink-jet ink that provides among the present invention may be used on minute-pressure electricity, heat foamable printer; The contained salt impurity that grades is few, and electrical conductivity is low, is difficult for the infringement shower nozzle; And can keep certain pH value, and be difficult for hydrolysis takes place, can store for a long time; Its degree of fixation, washing fastness, light fastness all can reach higher specification requirement; Do not contain azo dyess such as aromatic amine,, meet national standard-GB18401 human body safety.
