mercerization

[‚mər·sə·ri′zā·shən]
(textiles)
A technique used to increase luster, dye absorptivity, and strength in cotton and linen goods; the cloth is put into a heated solution of caustic soda at a controlled temperature, then washed, neutralized, and rinsed.

During mercerization caustic soda reacts with the cellulose and breaks down the hydrogen bonding of the atoms in crystalline region of the cotton fibre.
It is concluded from the above study that, 100% cotton fabric significantly lose its degree of crystallinity (crystallinity %) during caustic scouring, bleaching and mercerization due to chemical degradation and elevated temperature impact, while desizing has no significant effect on crystallinity % (CI).

Mercerization leads to fibrillation which causes the breaking down of the composite fiber bundle into smaller fibers.
Mercerization is an alkali treatment to cellulose fiber that depends on the type and concentration of alkali solution, time of treatment and temperature.
Among the various pre-treatment or purification processes of cellulose textile fibers, only scouring and mercerization employ concentrated alkaline agents.
