Embodiment 1

[0026] (1) Configure a polymer modifier, based on its total weight, including the following components in mass percentages: 0.5% water-soluble polyester hot-melt adhesive, 10% modified cellulose, and 1.5% modified starch , 0.5% sodium carboxymethyl cellulose, 5% urea, 3% dicyandiamide, 2% sodium carbonate, 2% sodium chloride, 0.5% nano silicon dioxide, and the balance is water. After mixing the above components, fully stir until each component is fully swollen and dissolved, so that each component in the polymer modifier is completely dissolved and uniformly dispersed. In addition, for comparison, a control polymer modifier was configured, except that sodium chloride was not added, and the other components and contents were the same as above.

[0027] (2) Apply the prepared polymer modifier to the paper and treat it in an oven at 60°C to prepare transfer printing paper. The coating amount of the polymer modifier on the paper is 15g / m 2 . Then use an inkjet printer to spray r...

Embodiment 2

[0040] (1) configure the polymer modifier, based on its total weight, including the following components in mass percentages: 5% water-soluble polyurethane hot-melt adhesive, 5% modified guar gum powder, 0.5% modified starch %, urea 4%, triethylene glycol 1%, sodium bicarbonate 3%, nano silicon dioxide 0.5%, sodium sulfate 1%, and the balance is water. After mixing the above components, fully stir until each component is fully swollen and dissolved, so that each component in the polymer modifier is completely dissolved and uniformly dispersed. In addition, for comparison, a control polymer modifier was configured, except that sodium sulfate was not added, and the other components and contents were the same as above.

[0041](2) Apply the prepared polymer modifier to the paper and treat it in an oven at 50°C to prepare transfer printing paper. The coating amount of the polymer modifier on the paper is 12g / m 2 . Then use an inkjet printer to spray reactive dye ink (reactive dy...

Embodiment 3

[0044] (1) Configure polymer modifier, based on its gross weight, including the following components in mass percentage: 3% water-soluble polyester hot-melt adhesive, 2% sodium alginate, modified tamarind gum powder 3%, urea 3%, glycerin 5%, ammonium sulfate 3%, potassium chloride 2.5%, and the balance is water. After mixing the above components, fully stir until each component is fully swollen and dissolved, so that each component in the polymer modifier is completely dissolved and uniformly dispersed. In addition, for comparison, the polymer modifier of the control group was configured, except that potassium chloride was not added, and the other components and contents were the same as above.

[0045] (2) Apply the prepared polymer modifier to the paper and treat it in an oven at 90°C to prepare transfer printing paper. The coating amount of the polymer modifier on the paper is 20g / m 2 . Then use an inkjet printer to spray acid dye ink (acid dye CYAN) on the transfer print...

Abstract

The invention relates to a method for improving printing performance of real silk printed fabric. The method comprises the following steps: applying a macromolecular modifier to the surface of paper,after processing in 50-90 DEG C, obtaining transfer printing paper, wherein an increased weight of the paper is 10-20 g / m<2>, and the macromolecular modifier comprises the following components according to a mass percentage: 0.5-5% of a water-soluble hot melt adhesive, 2-12% of a thickening agent, 0.5-3% of an acid-base agent, 2-8% of a hygroscopic agent, 1-3% of inorganic salt, and the balance ofwater; using reactive dye ink or acid dye ink to perform ink-jet printing on the transfer printing paper, and obtaining the transfer printing paper printed with the ink after drying; performing hot-pressing lamination on the transfer printing paper printed with the ink and real silk fabric, after steaming and washing, obtaining the modified real silk printed fabric. The method is capable of solving problems caused by sizing pretreatment in a traditional printing method that a fabric color yield is low, a dyeing fixation rate is low and an environment is polluted.

Description

technical field [0001] The invention relates to the technical field of textile printing, in particular to a method for improving the printing performance of silk printed fabrics. Background technique [0002] Known as the "Queen of Fibers", silk fabrics are soft and smooth, soft and light to the touch, and cool and comfortable to wear. At present, silk printing methods mainly include inkjet direct injection printing and traditional rotary screen printing. These two methods have good printing effects, but the printed fabrics need to be pretreated by sizing, and a large amount of dyes and paste additives are discharged during the subsequent washing process. sewage, causing environmental pollution; a large amount of paste on the surface of the fabric also hinders the dye macromolecules from coloring on the fabric. Silk fabric dry transfer printing is a new printing method, silk fabric does not need to be pretreated and dry transfer printing paper sprayed with dye ink is hot-pr...
