Printing liquid for inkjet printing of cotton fabric

Abstract

The invention discloses printing liquid for inkjet printing of a cotton fabric. The printing liquid is prepared from the following components in parts by mass: 20 to 40 parts of jujube skin pigment, 15 to 25 parts of maleic anhydride resin, 1 to 3 parts of a surfactant, 0.3 to 0.7 part of malic acid, 10 to 16 parts of a humectant, 1.5 to 3.5 parts of aloe vera gel, 6 to 12 parts of a viscosity modifier, 1 to 5 parts of an antibacterial agent, and 50 to 60 parts of deionized water. The printing liquid provided by the invention has the beneficial effects of being environmentally friendly, and capable of obtaining comfortable fabric handfeel and excellent color fastness to washing without pretreatment on the surface of the cotton fabric, and heating and baking after printing.

Description

technical field [0001] The invention belongs to the technical field of textile materials, in particular to a printing solution for inkjet printing of cotton fabrics. Background technique [0002] With the improvement of living standards and the development of science and technology, people have higher requirements for the appearance, color and performance of textiles. Fabric printing refers to the process of forming patterns on fabrics with dyes or paints. Fabric printing belongs to partial dyeing, which is one of the important ways of pattern decoration. The main methods of fabric printing are: direct printing, discharge printing, resist printing, pigment printing, transfer printing and digital inkjet printing. 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 t...

Problems solved by technology

[0004] Digital inkjet printing accurately prints the printing liquid onto the surface of the fabric in a non-contact manner. During the digital inkjet printing process of cotton fabrics, the existing printing liquid is not easy to combine and penetrate quickly with cotton fabrics. The absorption and utilization rate of cotton fabrics is not good, and the coloring speed is slow. , the coloring fastness is low, so in the prior art, before the digital printing of the fabric, the fabric needs to be treated before sizing to help improve the fixation rate and color fastness of natural dyes, but this will Increasing the process of printing and dyeing in digital printing has always been a major problem for printing and dyeing enterprises. It not only prolongs the process cycle, but also causes slow speed and low efficiency of inkjet printing.

On the other hand, the current printing liquids on the market still have problems such as insufficient printing fluency, poor long-term stability of printing liquids, etc., and the hand feeling of printing is poor, which needs to be improved.
