Cross-dyeing and union dyeing are simply opposite of each other. These two dyeing processes are done on the fabric which consists of more than one fiber. In the basic, Cross dyeing has two different color effects in one fabric. On the other hand, union dyeing has only one color effect on the fabric.
Cross dyeing:
Cross dyeing is a dyeing process in which two or more fiber is dyed with two different colors with different dyestuff in one fabric. It creates a special type of cross-melange effect on yarn, fabric, and even garments.
As an example:
A cross fabric made of =Polyester fiber yarn + Cotton fiber yarn
Then these two fibered fabrics will be dyed in one bath. The first polyester and then cotton will be done.
Polyester Dyeing= Dyed with dispersed dye yellow
Cotton dyeing = Dyed with reactive dye red
Finally, we get a Yellow+red cross melange= Cross dyed fabric
Union Dyeing:
Union dyeing is a dyeing process in which two or more fiber is dyed the same color with different dyestuff. It creates an even solid look on the fabric, yarn, and even garments.
As an example:
A union fabric made of =Polyester fiber yarn +Cotton fiber yarn
Then these two fibered fabrics will be dyed in one bath. The first polyester and then cotton dyeing will be done.
Polyester Dyeing= Dyed with dispersed dye yellow.
Cotton dyeing = Dyed same shade of yellow with reactive dyes.
Finally, we get a solid yellow color= Union dyed fabric

The basic difference between Cross dyeing and union dyeing:
Cross dyeing | Union dyeing |
Create Multi-color effect | Only one color effect |
Different fiber is dyed with different color | Different fibers dyed with the same color |
Easy to create effect during the dyeing | Difficult to match fibers with each other |
We can get multi-patterned fabric(Using different colors and different fibers) | Only one patterned fabric |
