Abstract

The invention provides a digital reactive dye printing process for a mulberry silk fabric. The process comprises the following steps: carrying out textile sizing, drying, carrying out jet printing, steaming, washing by cold water, washing by hot water, washing by soap, washing by hot water, washing by cold water, and drying, wherein a sizing agent used in the textile sizing step comprises the following components in percentage by weight: 1%-3% of sodium sulfate powder, 0.5%-1% of sodium alginate, 3%-5% of urea, 0.5%-1.5% of sodium hydrogen carbonate, 1%-2% of modified starch, 5%-7% of electrolyte and the balance being water. By virtue of the process, the digital printing color yield of the mulberry silk fabric is increased, the inkjet printing color depth on a textile is increased, the color difference between a pattern on the textile and an electronic pattern is reduced, and the hand feel of the fabric is good.

Description

technical field [0001] The invention relates to a digital printing process, in particular to a reactive dye digital printing process for mulberry 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, digi...
