Mercerized Cotton

While I was ironing my shirt in the morning, I read a tag a little below the back of my collar- Mercerized Cotton; I thought I will look it up on Google.

Here is what i found: Mercerization is a treatment for cotton fabric and thread mostly employed to give cotton a lustrous appearance. The series of processes was devised by John Mercer in the middle of 19th century.

Question - What are the advantages of using mercerized cotton?
Answer- Mercerized cotton has a higher luster, greater strength, holds more dye, and does not shrink as much when washed as unmercerized cotton.
