The invention discloses ink-jet printing pigment ink and an ink-jet printing method. The ink-jet printing pigment ink comprises the following components by weight percent: 10%-30% of organic pigment dispersion liquid, 0.1%-25% of adhesive, 0.1%-10% of first substance and 0.1%-10% of second substance. The first substance has the general formula of a compound of R-O-QnA-M+, wherein R is alkyl group, aryl group, alkaryl group or alkylene group, Q is repeated ethyoxyl group or propyl group, n is more than 4 and less than or equal to 10, A-is sulfate radical, sulfoacid radical or phosphate radical, and M+ is potassium ion, sodium ion, lithium ion or amino ion; and the second substance has the general formula of a compound of XQnR'-Y-R, wherein X is hydroxyl group or amino group, Q is repeated ethyoxyl group or propyl group, n is more than 4 and is less than or equal to 10, R' is alkyl group from C1 to C6, Y is oxygen, nitrogen or sulphur, and R is alkyl group, aryl group, alkaryl group or alkylene group. The ink-jet printing pigment ink has good storage stability and is not easy to block a shower nozzle.
Description
technical field [0001] The present invention relates to an ink-jet printing method and ink-jet printing equipment and ink-jet printing ink used therein, in particular to a method for directly performing ink-jet printing on pure cotton or fabrics containing at least 50% cotton. Ink printing equipment and inkjet printing inks. Background technique [0002] As an advanced technology in the textile industry, digital inkjet printing uses a computer-controlled printing system to directly spray ink onto the surface of cotton, linen, silk, chemical fiber and other fabrics to print various patterns and patterns. Compared with the traditional printing process, digital inkjet printing saves the plate making process, has high production efficiency and no pollution in the production process. [0003] At present, there are two main types of inks used in digital inkjet printing: dye-based and pigment-based. Dye-based inks are divided into three kinds of inks: disperse dyes, acid dyes and...
