Application of crab shell chitosan on nonwoven wool

Textile substrates can be coated with suitable polymer solutions to enhance the surface functionality. This paper highlights the deposition of chitosan (CHT) on wool nonwoven substrates using traditional pad-dry-cure method; and its potential application in medical textiles specifically wound dressing products. Wool nonwoven substrates were prepared by pre-treating with BMIMCl (ionic liquid) and application with different concentrations of CHI. The liquid uptake and antimi crobial efficacy was evaluated. It was shown that 0.3% CHI treated samples demonstrated good liquid uptake and excellent antimicrobial properties.
