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 that is used is vertical. It consists of a vertical washing chamber.
Types of Mercerizing Processes?
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.

In sum, I have given the basic idea of the mercerizing process. So, do the same as is given 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 the biofinish.
