Embodiment 3

[0032] Silk power spinning fabric (76g / m 2 ) as an example, using Embodiment 1 and Embodiment 2, the digital printing slurry processing and finishing described in Comparative Example 1 to Comparative Example 5, the specific steps are: pre-treatment of fabric sizing—drying—digital printing—steaming—washing—drying dry - finished product.

[0033] Fabric sizing pre-treatment: soak the silk electrospun fabric in the digital printing slurry, the temperature of the digital printing slurry is 30°C;

[0034] Drying: select the temperature as 105°C, and the drying time is 10 minutes;

[0035] digital printing;

[0036] Steaming: select the temperature as 105°C, and the steaming time is 30 minutes;

[0037] Washing: choose pure water washing at 50°C;

[0038] Drying: select the temperature as 105°C, and the drying time is 10 minutes;

[0039] Finally, get the finished product, and conduct a performance test on the finished product, the test method is as follows:

[0040] Oxidation...

Embodiment 2

[0052] Compared with Example 2 and Comparative Example 2, it can be seen that after the gallnut extract is added, the fabric has a bacteriostatic rate of 88.7% to Staphylococcus aureus, and a bacteriostatic rate of 87.0% to Escherichia coli. antibacterial properties. After the digital printing slurry in Comparative Example 2 was placed for 24 hours, the viscosity dropped by 30%, and the stability of the digital printing slurry became worse, while after the digital printing slurry in Example 1 was placed for 24 hours, the viscosity decreased With only 4%, gallnut extract also has the effect of maintaining the stability of the digital printing slurry.

[0053] Comparing Example 2 with Comparative Example 3, it can be seen that after adding isoflavone glucoside, the oxidation resistance of the fabric is increased from 11.3% to 66.3%, and isoflavone glucoside can obviously improve the oxidation resistance of the fabric.

[0054]Embodiment two compares with comparative example fou...

Embodiment 1

[0064] Add antibacterial agent, antioxidant and color-fixing agent in the described digital printing slurry in embodiment one or embodiment two, described antibacterial agent, antioxidant and color-fixing agent do not form crystalline structure in colloidal solution and can play Respective functions, the digital printing slurry remains stable and can be used normally, and compared with the traditional digital printing pretreatment agent, the digital printing slurry in embodiment 1 or embodiment 2 has high stability. Digital printing is carried out using the digital printing paste in Embodiment 1 or Embodiment 2, and the steps of fabric sizing pre-treatment and post-finishing in the traditional digital printing process are combined into one step as the fabric sizing pre-treatment step, the process is simple and the energy consumption is low.

Abstract

The invention discloses digital printing pulp, which is prepared from the following components in parts by weight: 2 to 10 parts of thickening agent, 2 to 8 parts of viscosity regulator, 1 to 6 parts of antibacterial agent, 1 to 5 parts of antioxidant, 1 to 5 parts of color fixing agent and 80 to 100 parts of water. A colloid solution can be formed by the thickening agent, the viscosity regulator and the water; the antibacterial agent, the antioxidant and the color fixing agent are added into the colloid solution; the antibacterial agent is selected from a Chinese gall extract of which the main component is Chinese gall tannin; the antioxidant is selected from isoflavone glucoside; the color fixing agent is selected from rubiadin. Because the Chinese gall extract, the isoflavone glucoside and the rubiadin are natural compounds with good water solubility, the molecular weight is small, difference among dissolubility, a pH value and the like is avoided, a crystalline structure is difficultly formed by the thickening agents or the viscosity regulators in the colloid solution, and the stability of the digital printing pulp can be maintained. The invention also provides a method for carrying out digital printing on fabrics by adopting the digital printing pulp. The process is simple, and the energy consumption is low.

Description

technical field [0001] The invention relates to a digital printing slurry and a digital printing method. Background technique [0002] Digital printing is printing using digital technology. The pattern is input into the computer in digital form, edited and processed through the computer printing color separation and drafting system, and then the computer controls the micro piezoelectric inkjet nozzle to spray the special dye directly into the computer. On the textile, form the desired pattern. The promotion and application of digital printing technology has had a major impact on the development of my country's textile industry. [0003] The traditional digital printing process flow is: [0004] Pre-treatment of fabric sizing—drying—digital printing—steaming—washing—drying—finishing—washing—drying—finished product. [0005] Existing digital printing pastes can only be applied to the pre-treatment of fabric sizing, and additional finishing agents need to be prepared for pos...
