Abstract

The invention belongs to the field of development of natural plant dyes and particularly relates to a preparation method for extracting a natural dye from stems and leaves of celosia cristata L. and application of the method. The preparation method comprises the following steps: adding extract of stems and leaves of celosia cristata L., a wetting agent, a penetrating agent, acrylic emulsion, a softening agent, a cosolvent, a surfactant and a sterilizing agent into de-ionized water in percentage by weight, and agitating uniformly; adjusting the system to be alkaline; heating to 60-70 DEG C and continually agitating for 1-3 hours; preserving heat and curing for 2-5 hours; cooling the solution to room temperature; and filtering the solution to obtain a final digital ink-jet printing ink product. Before the ink provided by the invention is used for carrying out digital jet printing on a textile, pre-treatment procedures of sizing and the like do not need to be carried out on the textile, so that a jet printing process is shortened; and the dyed textile has good water vapor permeability and has a high comfort level.

Description

technical field [0001] The invention belongs to the development field of natural plant dyes, in particular to a preparation method and application of natural dyes extracted from stems and leaves of cockscomb flowers. Background technique [0002] The so-called digital inkjet printing is to use scanners, digital cameras and other input means to input the pattern into the computer in digital form. After image software processing, the digital inkjet printing machine controlled by the computer directly sprays the printing ink to various Various input patterns are printed on the fiber fabric to obtain various printed fabrics. As one of the main consumables of digital inkjet printing, printing ink is also a key factor determining the success of inkjet printing technology. [0003] In the prior art, commonly used printing inks are generally small molecule dyes, which are mainly prepared from dyes, dispersion media, antibacterial agents, pH regulators, moisturizers, etc., and have ...
