Mercerization

Part of speech: noun

Definitions

1. A technique involving the use of alkali on cotton to significantly improve its dye retention and physical attributes while reducing fabric shrinkage
2. A process that treats cotton fibers with a caustic soda solution to enhance their strength, luster, and dye affinity while minimizing shrinkage
3. This method uses sodium hydroxide to modify the properties of cotton, thereby increasing its durability, shine, and color absorption while decreasing fabric shrinkage

Etymology: Mercerization is named after a person, though the connection is easy to miss. John Mercer, an English calico printer and chemist, discovered in 1844 that cotton soaked in strong caustic soda shrank and became glossier and stronger. The process that bears his name is "mercerize," a verb formed from his surname, and the noun "mercerization" names the treatment itself. The point of the process is that the cotton fibres swell and take on a silky lustre that untreated cotton lacks, so it dyes more deeply and holds its colour better. The noun is simply the verb with the common suffix "-ation," which turns an action or process into a noun, so the word reads as "the act of mercerizing." Its meaning has stayed fixed on the treatment since the surname-based verb came into use, with no shift into unrelated senses.
