In this work, an influence of oxidation with potassium
permanganate (KMnO4) of different concentration, on the structure,
sorption properties and surface charge of cotton yarn was investigated.
Cotton oxidation was performed at const pH for 1 hour. After the
oxidation,
samples were washed, dried and characterized from the aspect of change in
morphology, sorption properties, COOH group content and surface charge.
The results have shown that oxidation with the most concentrated solution
of KMnO4 led to significant increase of COOH group content in the sample
(around 6 times), which thus led to increment of moisture sorption as well
as reduction of zeta potential in basic range. These results confirmed
that KMnO4 could be successfully used for cotton oxidation with aim to
improve
sorption properties.
