The influence of peroxide bleaching and slack-mercerization on the amount of acidic groups in regenerated fibres were studied. For all three types of fibres the amount of accessible carboxyl groups was lowered by an increase in the degree of crystallinity.

FRAS ZEMLJIČ, Lidija, STENIUS, Peer, LAINE, Janne, STANA-KLEINSCHEK, Karin. Topochemical modification of cotton fibres with carboxymethyl cellulose.

Adsorption of carboxymethyl cellulose (CMC) as a method to introduce charged (ionizable) groups onto cellulose cotton fibre surfaces was investigated. The adsorbed charge correlated linearly with the amount of CMC adsorbed. The total charge of the cotton fibres could be increased by more than 50% by adsorption of CMC.
