Embodiment 1

[0024] A digital printing process for silk fabrics, comprising the following steps: silk fabric → low-temperature plasma treatment → padding pretreatment liquid → drying → inkjet printing → drying → dry heat color fixing → cold water washing → warm water washing → soaping → warm water washing → drying, the content of each component of the pretreatment liquid in the padding pretreatment liquid is as follows: sodium alginate 7g / L, baking soda 40g / L, urea is 40g / L, defoamer 10g / L.

[0025] Wherein, in the low-temperature plasma treatment step, a discharge plasma treatment device is used to modify the surface of the silk fabric. The discharge plasma treatment device includes two discharge electrodes, which are embedded in a barrier medium, and the distance between the plates is 5 cm. The discharge plasma treatment device uses O 2 It is the plasma working gas, the processing power is 60W, the silk fabric is placed between the two electrode plates, not in contact with the two ele...

Abstract

The invention provides a digital printing process for a real silk fabric. The digital printing process comprises the following steps: carrying out low-temperature plasma treatment on the real silk fabric, padding a pretreatment solution, drying, carrying out inkjet printing, drying, carrying out dry heat color fixation, washing by cold water, washing by warm water, washing by soap, washing by warm water, and drying, wherein the pretreatment solution subjected to padding comprises the following components: 5-10 g/L of sodium alginate, 30-50 g/L of sodium hydrogen carbonate, 30-50 g/L of urea and 5-15 g/L of a de-foaming agent. By virtue of the process, the digital printing color yield of the mulberry silk fabric is increased, the digital printing color depth on a textile is increased, and the color difference between a pattern on the textile and an electronic pattern is reduced; the real silk fabric is high in color fastness, and multiple washing experiments prove that the real silk fabric still cannot fade and lose color even in a severe experimental environment.

Description

technical field [0001] The invention relates to a digital printing process, in particular to a digital printing process for silk fabrics. Background technique [0002] Digital inkjet printing technology is a great expansion of inkjet printing in the field of industrial applications. When modern computer inkjet printing technology is used for textile printing, various input means such as scanners, digital cameras, digital cameras, etc. can be used to digitally input the required patterns into the computer, and then printed and divided by various drawing software (photoshop). After the color system (CAD) is processed, the computer-controlled digital inkjet printing machine directly sprays the printing ink onto various fiber fabrics to print various patterns required. This printing technology is called digital inkjet printing. ink print. [0003] In recent years, digital printing technology has developed rapidly. Compared with traditional printing, digital printing has a cle...
