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 a digital printing slurry, which comprises the following components in parts by weight: 2-10 parts of thickener, 2-8 parts of viscosity regulator, 1-6 parts of antibacterial agent, 1-5 parts Antioxidants, 1 part to 5 color fixing agents and 80 parts to 100 parts water; the thickener, viscosity modifier and water can form a colloidal solution, and antibacterial agents, antioxidants and color fixing agents are added to the colloidal solution, so Said antibacterial agent is selected Galla galla extract, and main component is Galla galla tannin, described antioxidant selects isoflavone glucoside, and described color-fixing agent selects rubidin, because Galla galla extract, isoflavone glucoside and madiadin are all water-soluble A good natural compound has a small molecular weight, no difference between solubility and pH value, etc., is not easy to form a crystalline structure with a thickener or a viscosity regulator in a colloid solution, and can maintain the stability of the digital printing paste. The invention also provides a method for digitally printing fabrics by using the digital printing paste, which has simple process and low energy consumption.

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...
