Abstract

The invention discloses an environment-friendly silk printing method, which comprises the following steps: (1) performing enzyme pretreatment on a fabric, namely putting the silk fabric subjected to degumming and tentering into an enzyme solution for pretreatment; (2) performing sizing; (3) drying; (4) making a document, wherein jet printing is generated by color card software, and ink for the jet printing is regenerative reactive dye-based ink; (5) performing jet printing; (6) steaming and drying; (7) washing, namely washing with cold water, then soaping, and washing with cold water again; and (8) performing tentering drying.

Description

technical field [0001] The invention relates to an environment-friendly silk printing method, in particular to a silk printing method using an enzyme auxiliary agent. Background technique [0002] Digital inkjet printing is a printing technology that has developed rapidly in recent years. It sprays ink containing pigments on the fabric from a nozzle under the drive of compressed air, and is controlled by a computer to form patterns on the fabric according to the design requirements. According to the ink system After proper post-treatment, the fabric has a certain color fastness and vividness. Silk fabrics have high requirements for printing fineness. It is very important to pretreat the fabric to reduce the degree of ink bleeding on the fabric. The ink bleeding process on the fabric can be divided into two parts. One is the bleeding of inkjet printing. The second is the infiltration produced during the steaming process. Therefore, the fabric needs to be sizing pretreated b...
