CHEMICAL MODIFICATION OF CELLULOSE
Thermolytic degradation of cellulose is dependant on its initial DP, accessibility and on
the method and temperature of the treatment. A limiting DP could be detected in the
depolymerizing reaction. The deteriorating action of aggressive water could be demonstrated.
Quantitative correlation was elaborated concerning the role of accessibility in the reaction
between cellulose and reactive dyestuffs. The role of temperature was cleared up in the
ceIlulose-caustic soda interaction. New bleaching process was elaborated with the use of singlet
oxygen. Physical characteristics, amount of releasable formaldehyde and colouristic influence of
resin finishing of cotton could be optimized
