Digital printing process for polyester-cotton fabric

Abstract

The invention relates to a digital printing process for a polyester-cotton fabric. The digital printing process comprises the following process steps: (1) sizing a polyester-cotton fabric; (2) digital printing: carrying out spray printing according to a pattern requirement of rip printing software, generating cyan by virtue of color card generation software (C:100, M:100, Y:100 and K:100), and carrying out unreeling and sequential digital printing on the fabric reeled in the step (1), wherein a printer comprises a first spray head and a second spray head, the first spray head is used for spraying and printing disperse dye ink, the second spray head is used for spraying and printing active dye ink, and a printing condition is that bidirectional four channels are adopted; (3) high-temperature baking: baking the digital-printed fabric in the step (2) at 180-190 DEG C for 40-50 seconds; (4) cotton-cloth steaming; (5) a washing and soaping process: carrying out open-width washing on the fabric processed in the step (4); and (6) shaping and drying: adding a softening agent and a color fixation agent into the fabric processed in the step (5) for shaping, and drying at a temperature of 150-160 DEG C, wherein the speed of a drying vehicle is 40m/min-50m/min.

Description

technical field [0001] The invention relates to a digital printing process, in particular to a digital printing process for polyester-cotton fabrics. Background technique [0002] Polyester-cotton fabric, with polyester as the main component, is a textile made of 60%-67% polyester and 33%-40% cotton blended yarn. It combines the advantages of polyester fiber and cotton fiber. Good elasticity and wear resistance, stable size, small shrinkage, tall and straight, not easy to wrinkle, easy to wash, quick-drying. For polyester-cotton fabrics, especially when the two components are equal, the existing digital printing process does not have a good solution, and usually only the pigment printing process can be used to solve the problem. The pigment digital printing process is: fabric pretreatment— Pigment digital printing printing—drying—high temperature baking—post-processing, but the paint ink digital printing process still has the following shortcomings: 1) The color is not brig...

For polyester-cotton fabrics, especially when the two components are equal, the existing digital printing process does not have a good solution, and usually only the pigment printing process can be used to solve the problem. The pigment digital printing process is: fabric pretreatment— Pigment digital printing printing—drying—high temperature baking—post-processing, but the paint ink digital printing process still has the following shortcomings: 1) The color is not bright enough to meet the needs of various digital printing products; 2) The color fastness is especially Rubbing fastness is difficult to meet various requirements, there are technical contradictions in ink fluency and color fastness requirements, ink is not mature enough; 3) hand feel is difficult to meet customer requirements
