Inkjet printing not only requires high-precision nozzle technology and high-precision control technology, but also requires ink (ink) with high purity, high concentration, high fastness, and high stability to match it before it has use value.
Digital inkjet printing process
The process of inkjet printing depends on the ink used. Generally, acid dyes are mainly used for carpet printing, disperse dyes are mainly used in polyester fabrics, and reactive dyes are mainly used in cotton fabrics. The following is an example of the inkjet printing process of reactive dye ink used in cotton fabrics.
Fabric pretreatment → drying before printing → inkjet printing → drying after printing → steaming (100 ~ 102 ℃, 8min) → washing → drying.
The pretreatment of the fabric is mainly due to the wettability of the fabric and the capillary effect between the fibers. In conventional fabric printing pastes, appropriate printing fillers must be used to prevent seepage. The general inkjet printer can only use low-viscosity water-based ink. If it is directly printed on the fabric, the dyeing solution will permeate in all directions, so the printed fabric must be properly pretreated. When spray printing, special software is used to print lines and patterns at an appropriate resolution. The post-processing of printed fabrics is mainly to improve their color fastness.
