Mercerization

Mercerization

A chemical treatment of cotton (or linen) yarn with a high-concentration sodium hydroxide (caustic soda) solution, which modifies the structure of the fibre giving silky lustre, increased strength and improved dye absorption. The yarn is held under tension during the treatment to keep its shape, then washed and neutralized. Yarn mercerization is carried out in hank form and significantly increases dye uptake during dyeing.
