Problems solved by technology

Sodium alginate is one of the most suitable natural pastes for digital jet printing of reactive dyes. Many pastes with other carbohydrate structures will react with reactive dyes, resulting in a decrease in color yield, or the fabric feels bad because the paste is not easy to wash off. hard
The amount of sodium alginate will not only affect the fineness of the printing effect, but also affect the permeability of the dye

Abstract

The invention discloses a digital jet printing technology of modal knitted fabric. The technological process comprises sizing mixing, sizing, setting and spray printing, steaming, washing with cold water, washing with hot water, soaping, washing with hot water, washing with cold water and drying. An optimized printing paste formula is adopted for inkjet printing of fabric, the color fastness of the printed fabric is high, the washing fastness is level 4-5, the dry-rubbing fastness is level 4-5, and the wet-rubbing fastness is level 4; and modified starch can inhibit bleeding of dye on the fabric, and improve the apparent dye yield, the print through performance and the pattern definition after printing.

Description

[0001] technical field [0002] The invention belongs to digital jet printing, in particular to digital jet printing of modal knitted fabrics. [0003] Background technique [0004] Digital jet printing is a new printing technology that appeared internationally in the 1990s. It is an advanced printing method with low pollution, low waste water, and high definition. It is a major breakthrough in traditional printing technology. Modal (Moda1) fiber is a combination of the luxurious texture of natural fibers and the practicability of synthetic fibers. It has the softness of cotton, the luster of silk and the smoothness of hemp, and its water absorption and air permeability are better than cotton. High, bright and rich colors. Sodium alginate is one of the most suitable natural pastes for digital jet printing of reactive dyes. Many pastes with other carbohydrate structures will react with reactive dyes, resulting in a decrease in color yield, or the fabric feels bad because th...
