What is Mercerization process?

What is Mercerization process? Mercerization is a process in which textiles (typical- ly cotton) are treated with a caustic (NaOH) solution to improve properties such as fiber strength, shrink- age resistance, luster, and dye affinity. The caustic actually rearranges the cellulose molecules in the fiber to produce these changes.

Can cotton heat set?
