Polyamide fibers, Polyesters and synthetic are more susceptible microbial growth that brings odor from the body. In order to overcome these microbial population on textiles, the antibacterial, antifungal etc., has to be imparted in textiles. Everyone is expecting to have textiles with good antimicrobial property. Use of chemical will affect the human beings and cannot be easily degraded in environment.
Chitosan is a de-acetylated form of chitin has versatile application such as antimicrobial activity, biodegradability, biocompatibility, nontoxicity and physic- chemical properties. Wound dressings wettability and antimicrobial property against Pseudomonas aeruginosa has increased by treatment with chitosan carboxylic acid functionalized poly(propylene) (PP) using water soluble carbodiimide chemistry. Cotton fibers contain large amount hydroxyl that are hydrophilic in nature. When they absorb water during washing and shrinks and whrinkles because cellulose macromolecules will undergo plastic deformation. The cross linking of cellulose with chiotsan to fibre will prevents cellulose displacement.
