There are two main methods of fabric printing and dyeing, as the traditional paint printing and the reactive printing.
Reactive printing is that under a certain condition, the active gene of dye binds to the fiber molecule and the dye penetrates into the fabric, then the dye and fabric have chemical reaction making the dye and fiber form a whole. Paint printing is that dye physically combines with fabric through adhesive.
Reactive printing fabric has soft and smooth hand feeling, which looks like mercerized cotton. It has good dyeing effect both the obverse side and the reverse side. While paint printing fabric has stiff handle and looks like ink painting effect.
Characteristics of Paint Printing
The process is simple and the cost is low. But color fastness is poor. Fabric is not washable. It has poor environmental protection performance. The formaldehyde content is higher than that of reactive printing fabric. The printed part is sticky. If fabric is not added softener, it is stiff. If fabric is added softener, the formaldehyde content will be higher.
Characteristics of Reactive Printing
The fabric has good air permeability, excellent fastness and soft handle. Generally reactive printing fabric is environmentally-friendly and harmless to human body for sure.It has good color and good hand feeling.
Identification Method
- By color: The color of paint printing is not bright and it is dull. It seems that the color is floating on the surface of cloth. It is like to brush a coat of paint on the wall.
- By luster: By calendering process, paint printing fabric is shiny. But after washing, the shiny surface will gone.
- By smell: Paint printing fabric is added many adhesives. It is directly set without washing process. So the finished fabric has a strong smell.
