Printing Fabric: the difference between paint printing and reactive dye printing

Apr 20, 2019

What is the difference between paint printing and reactive dye printing? What are their advantages? The so-called printing is to process the dye or paint into a color paste, apply it locally to the textile, and print the pattern. In order to complete the textile printing, the processing method is called the printing process. The printing fabric is produced thereby.
01, concept
Paint printing: Paint printing is based on high molecular weight polymer (adhesive), using a water-insoluble colored substance (pigment) to form a firm, transparent, wear-resistant colored film on the fabric, and the coating is mechanically fixed to the fabric. The printing method on the.
Dye printing: the printing and dyeing are the same in terms of the mechanism of dyeing the dye on the dye, except that in the printing, the dye of a certain color is applied locally to the textile according to the pattern, and the dye is dyed on the dye after a certain treatment. A printed product having one or more colors is obtained on the textile. Therefore, the printing can also be said to be "local dyeing".

02, the basic principle
Principle of coloring of paint: Paint printing is a printing method in which the adhesive forms a firm, transparent, and abrasion-resistant film on the fabric to mechanically fix the coating on the fabric.
What is the difference between paint printing and reactive dye printing? What are their advantages?
Dyeing raw materials for dyes: The physical, chemical or physicochemical combination of dyes (or pigments) and textile materials during dyeing gives the textile materials a bright, strong color process.

03, advantages and disadvantages
Paint printing
advantage:
Simple to use, simple process, high labor productivity, and reduced wastewater discharge
Wide chromatogram, high lightfastness, clear lines and contours
Suitable for special printing methods, can also be used for discharge printing, anti-dye printing
Color matching is easy, color light replay is good
Suitable for fabric printing of various fiber materials, especially blended fabrics.
Disadvantages:
Poor hand feeling, dry and wet rubbing fastness is not good
Fire oil is used in the emulsified paste to pollute the air; the monomers for preparing the binder are mostly toxic.
The color is less vivid than the dye printing with its equivalent structure
The adhesive is easy to crust and is more likely to clog the mesh
Dye printing (taking reactive dyes as an example)
advantage:
Variety, complete chromatography, bright color
It is convenient to prepare color paste, simple printing process, good effect and less rickets
Good wet processing fastness
Low printing cost, easy to color match
Disadvantages:
Most of them are not resistant to chlorine, and the fixing rate is low. Some reactive dyes have a large directness (affinity), which is liable to cause staining during soaping, especially when the ink is dark.
04, District
The biggest difference between dye printing and paint printing is that the paint printing is combined with the fabric in a physical bonding manner, and the dye printing is directly combined with the fabric by van der Waals force.
Paint material printing can be used for the processing of any fiber textile. It has superiority in the printing of blended and woven fabrics, and the process is simple, the chromatogram is wide, the flower shape is clear, but the hand feel is not good and the rubbing fastness is not high. Their light fastness and dry fastness are good and even excellent, so they are widely used in decorative fabrics, curtain fabrics and apparel fabrics that require dry cleaning.
How to distinguish between dye printing and paint printing
Paint printing and dye printing can be distinguished by comparing the difference in hardness between the printed and unprinted parts of the same piece of fabric. The paint print area is slightly harder than the unprinted area and may be a little thicker. If the fabric is printed with a dye, there is no significant difference in hardness between the printed and unprinted portions.
