Mercerized fabric dyeing Process is a special dyeing process. Here two types of mercerization fabric dyeing processes are available.

  1. One is yearn mercerized fabric process
  2. Another is the Grey mercerized fabric dyeing process

Now we discuss the both mercerized fabric dyeing process. Here the fabric is knitted with mercerized yearn. So that fabric is like bleached fabric. Here I share my experience with this process. I have applied many processes for this fabric and fixed a process. By which we can avoid Unveng dyeing, Running shade and Dye spot, Caustic spot, etc.

Difference between the dyeing process of the yarn and gray mercerized:

Yarn Mercerized= Scouring and bleaching done on yarn dyeing section.
