Possible mechanism of mercerization treatment on cellulose fibres [courtesy of reference 24 copyright Susheel et al.
Cellulosic recycled fibres after mercerization treatment
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 of agave fibers was performed for 24 h in a 5% solution of NaOH at room temperature.
For most treatments, fiber density increased especially after mercerization which also caused an increase in roughness.
This paper investigates the application of nanoparticles of zeolite on cotton and polyester fabric after well known surface modifications--cotton mercerization
and PET alkaline hydrolysis.
1]) could be useful for determining how the crystallinity index (CI) decreases with increasing strength of alkali during mercerization
STEX followed by mercerization
leads to an increase in the amount of cellulose nanofibrils.
leads to fibrillation which causes the breaking down of the composite fiber bundle into smaller fibers.
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.
