3.8 Limitations
• Cationizing agents are mainly made up of amines so the odour of ammonia on the
treated substrate is an issue.
• To control the process of cationization is a laborious task.
• High cost of the commercial cationizing agents.
• Cationizing agents tend to show low fixation rate in the exhaust process and
thus higher amount of chemicals are required. Along with it, the normal dyeing
procedure requires certain modification for treating cationized cotton.
• Limited number of dyes show good result in dyeing cationized cotton. Therefore,
choosing the correct dye is important.
4 Conclusion
Surface modification of cotton by cationization process using a variety of cationizing
agents become water, energy-saving and environment-friendly process for anionic
dyeing and finishing of textiles [77]. It can be stated that the cationizing agents used
for cationization do not affect the physical property of the cotton but chemically
develops the cationic sites on its surface. The cationized cotton also denotes higher
degrees of dye exhaustion, improved colour strength and strong ionic fixation related
to cotton due to the absorption of electrostatic attraction rendered by cationic sites
for anionic dyes [78]. It has also been observed that the cationic group of many
cationizing agents on the cotton substrate serves a dual functionality like antibacterial activity, UV protection etc. [79]. To highlight, the two main criteria are resolved
by the cationization process. First eliminating the requirement of electrolytes i.e.
inorganic salt and alkali in few dyeing processes and second to diminish environmental problems. Along with this, many cationizing agents on cotton control the
growth of bacteria and protects it from harmful UV rays. The future is bright for the
cationization process if the commercialization of cationizing agents is considered.
Effluent load can be controlled if the process is introduced in the textile industry.
It can be concluded that cationization can be easily used as dyeing auxiliary and
finishing auxiliary for surface modification of cellulosic textiles that will invite novel
achievement in future for the textile industry.
