Cationization as Tool for Functionalization of Cotton
3.1.6 Cross-Link Modification
In cross-link modification, polymer or fibre are chemically joined forming a covalent or ionic linkage [24]. Such modifications are used to improve certain physical
properties of fibres.
3.1.7 Nanotechnology
The application of nanomaterials on textiles offers high-performance functionality,
which is vigorously used for finishing, coating, dyeing etc.
3.1.8 Biopolymer Application
The polymers which are produced by living organisms are known as biopolymers.
Biopolymers are biodegradable and eco-friendly [25, 26]. Other than starch or sodium
alginate, commonly used biopolymer in textiles are chitosan and carrageenan derived
from carbohydrate family, they form a covalent linkage with the substrate or other
agent offering durable and permanent effect [27].
3.1.9 Chemical Addition
These treatments are commonly used for finishing processes. Examples of this are,
cyclodextrins used for fragrance finishes, silicones used for water repellency, fluorocarbons used for flame retardancy, DMDHEU used as cross-linkers, silicone-based
softeners for textiles, zinc/titanium oxides for antimicrobial finish and UV protection
finish, etc.
3.1.10 Cationic Compound Addition
The process where a cationic compound is applied on the cotton surface is known as
cationization. The popularly cationic agents used for the process are amines and/or
quaternary ammonium compounds. They chemically modify the surface on cotton introducing permanent cationic sites. Other surface treatment methods used for
cationization include organic or inorganic chemical addition, biopolymer application
on different textiles etc. Lewis and Lei in early 1930s had reported and developed
various cationizing processes and cationic agents to be used on cotton substrates that
introduce cationic sites after application. These chemicals are as follows.
Quaternary ammonium chlorides like Glycidyl trimethylammonium chloride (Glytac A) [2], Betaine (N, N, N-trimethyl glycine), 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTMAC), polyepichlorohydrin acrylamides, polyamino chlorohydrin quaternary ammonium compound i.e. Cibafix WFF
