Abstract

The invention provides a digital printing process for a real silk fabric. The digital printing process comprises the following procedures: real silk fabric preparation; low-temperature plasma processing; pretreatment liquid padding; drying; inkjet printing; drying; dry heat fixation; cold water flushing; warm temperature washing; soaping; warm water cleaning; and drying, wherein pretreatment liquid in the pretreatment liquid padding contains the following components by contents: 5g/L-10g/L of sodium alginate, 30g/L-50g/L of baking soda, 30g/L-50g/L of urea and 5g/L-15g/L of a defoaming agent. By virtue of the digital printing process, the tinctorial yield of the digital printing of a silkworm silk fabric is increased, the color depth of the digital printing on a textile is increased, and the chromatic aberration with an electronic pattern is reduced; and furthermore, the color fastness is high, and multiple experiments prove that the fabric does not fade or lose color even at relatively hostile experimental environments.

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...
