What is Mercerizing
We know that mercerizing is an additional process to improve the physical and chemical properties of the cotton yarn or fabric. For cotton knit dyeing; mercerizing is done before dyeing. Mercerized fabric is more suitable than unmercerized fabric. This process also depends on the buyer’s requirements. It is not a common operation for cotton fabric. It is done for the sophisticated fabric. The machine which is used is vertical type. It consists of a vertical washing chamber.
Types of Mercerizing Process:
The following three types are the mercerizing process. They are-
- Grey mercerization (Knitted fabric before dyeing)
- Fabric mercerization(Yarn dyed fabric)
- Collar & Cuff mercerization.
Frequency of Mercerization:
Mercerizing processes are of two types. The following are the mercerizing types.
- Single Mercerization
- Double Mercerization

In sum, I have given the basic idea about the mercerizing process. So, do the same which is given in above.
Lastly, mercerizing plays a vital role in adding value to textile products. So, we should be careful about the mercerizing process of cotton fabric as well as bio finish.
