IPA: /ˌmɜːrsəraɪˈzeɪʃən/
KK: /mɜrˈsɛrɪzeɪʃən/
A method of treating cotton fibers or fabrics to improve their appearance and strength, developed by John Mercer in the 19th century.
The mercerization of the cotton fabric gave it a shiny and smooth finish.
Mercerization is derived from 'mercer' (from Old French *mercier*, meaning a dealer in textiles) and '-ization' (a suffix indicating the process of making or becoming). The term refers to the process of treating cotton fabric with sodium hydroxide to increase its luster and strength, akin to the qualities associated with fine textiles.
Think of a 'mercer' as someone who deals in fine fabrics, and remember that 'mercerization' is the process that enhances the quality of cotton to make it more like those luxurious textiles.
