How does it work? What makes it special?
Cationisation is the
modification of cotton
cellulose by using quaternary
ammonium compounds that
block negative OH groups,
thus resulting in
electropositive cotton
cellulose.
It is an alternative method for
achieving better adsorption of
chemical compounds and
substances; such as
dyestuffs, fluorescent
whitening agents, and other
textile auxiliaries.
How does it work? What makes it special?
Cationisation during the mercerisation process with an epihalohydrin results
in novel cotton cellulose that gives a new dimension to cotton pre-treatment
and finishing.

How does it work? What makes it special?
• It was found that cationization with an epihalohydrin
completely change the system dyestuff-cotton fibre and
do not obey any known law, which indicates the necessity
of further investigations of such modified cotton.
• It represents an exceptional potential for environmental
disposal of waste as well, as such modified cotton fully
adsorbs anionic surfactant and dyestuff.
• The main idea (Tarbuk et al. 2012) is to produce filter of
cellulose cationized during mercerization, and to use the
recycle textile cellulosic waste from textile and clothing
industry for its production. It is to point out that other
cellulosic materials CLY, CV can be used for this purpose,
as well.

• Idea
Who are the beneficiaries? What elements can be transferred to others? How could
countries in the Southern Mediterranean and Western Balkan area benefit from this
experience? Under what conditions?
What has worked particularly well?

What problems needed to be solved and how?
What are the conditions for success?
• Definition of the maximum amount of cellulose material
(g/mole) used in the reaction, the molar ratio of reagents
used, preferable ratio of EPTAC to cotton, and NaOH to
cotton; and the reaction efficiency.
• More eco-friendly cationic compound
• Optimization of process
• Cellulose regenerate
