Problems solved by technology

However, due to the small size, uneven temperature distribution in the steamer, and unstable steam pressure, uneven color development of printed patterns, insufficient color fastness, and water stains often occur during the steaming process. Therefore, it is urgent to develop a more efficient steamer. Suitable digital printing method for color fixing

Embodiment approach

[0034] Such as figure 1 Shown, a kind of cellulose fiber cold fixation color digital printing method comprises the steps:

[0035] (1) Select reactive dye ink; the raw materials of reactive dye ink are as follows by weight percentage: reactive dye 5-20%, water retaining agent 10-35%, surfactant 1-5%, film forming agent 1-5%, moisture absorption Antiseptic 1-3%, fungicide 1-2%, descaling agent 0.1-2%, buffer 0.1-3%, and the balance is water. The reactive dye is one or more of X-type reactive dyes, KN-type reactive dyes, and P-type reactive dyes. Specifically, X-3B brilliant red, X-6G bright yellow, X-7G bright yellow, KN-BGFN emerald Blue, X-B Brilliant Blue, P-WN Black; the water retaining agent is one or more of glycerol, diethylene glycol, polyethylene glycol 400, diethylene glycol butyl ether, N-methylpyrrolidone, The surfactant is one or more of Pingpingjia, surfynol 104E, surfynol 465, the film-forming agent is one or more of polyvinylpyrrolidone, carboxymethyl cellulos...

Embodiment 1

[0041] Reactive Dye Ink Preparation

[0042] The components and weight ratio of reactive dye ink are: 20% reactive dye, 30% water retaining agent, 2% surfactant, 2% film forming agent, 3% hygroscopic agent, 1% bactericide, 2% descaling agent, buffer Agent 0.5%, the balance is water.

[0043] The preparation method is as follows: first purify and concentrate the purchased commercially available reactive dyes, use nanofiltration to desalt, control the inorganic salt content of the purified dye to be ≤0.05%, and set aside; then add a specified amount of desalted Ionized water, start the mixer, and add a specified amount of surfactant at a speed of 600 rpm. Raise the temperature to 65°C, increase the speed of the mixer to 1300 rpm, add the specified amount of the above-mentioned purified reactive dye, and stir until the dye is completely dissolved. Leave it to stand for 1 hour, then filter through a water-based membrane filter with a pore size of 1 micron to obtain a reactive dy...

Abstract

The invention discloses a cold color-fixing digital printing method for cellulosic fibers, which comprises the following steps: (1) selecting of a reactive dye ink; (2) preparation for cloth conditioning: subjecting cellulosic fiber cloth to a double-nip-double-dip process by means of a padder containing a padding solution with pick-up controlled in a range of 75-80%; (3) digital printing: printing patterns on the cloth that is previously treated in step (2) by using the selected reactive dye ink by means of a digital printing material; (4) cold color fixation: simultaneously rolling the pattern printed cloth with a layer of plastic film, and placing the roll at room temperature for 5-6 hours, thereby completing the color fixation. The cold color-fixing digital printing method for cellulosic fibers is simple and convenient in operation of process, high in flexibility, high in efficiency and low in cost with effects of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a textile printing and dyeing method, in particular to a cellulose fiber cold-fixing digital printing method. Background technique [0002] Textile digital inkjet printing using crystal piezoelectric technology is a new printing method that has developed rapidly in recent years. Its flexible, fast, and fine features adapt to the needs of today's market for personalization, small batches, multiple varieties, and high precision, leading more people in the industry to choose digital printing. Due to the huge market demand for reactive printing of cellulose fiber fabrics, making it Reactive dye digital printing has become a research hotspot. [0003] At present, cellulose fiber fabrics are digitally printed with reactive dye inks, and the process is: (fabric) fabric—pretreatment—drying—inkjet printing—drying—steaming and color fixing—washing— Drying and finishing. After digital printing of cellulose fibers, the steaming method i...
