Biomedical textiles through multi-functioalization of cotton fabrics using innovative methoxy polyethylene glycol-N-chitosan graft copolymer
Original language description
Multi-functioalization of cotton fabrics was developed by a novel finishing formulation. The method is based on chitosan?N-polyethylene glycol graft copolymer along with citric acid and sodium hypophosphite (SHP) as catalysts. Treatment of the cotton fabric resulted in the chemical attachment of the copolymer to the cotton fabric via bridging ? based esterfication where the latter involves reaction of one molecule of the polycarboxylic acid (citric acid) with both the amino group of the copolymer and the hydroxyl groups of cotton. Inclusion of the copolymer in the cross-linked structure of cotton as well as by hydrogen bonding and van der Waals forces are additionally possible. The pad dry-cure method was used for the cotton fabrics treatment with aqueous solution of prepared copolymer along with citric acid and SHP. The so treated fabrics were monitored for copolymer content (expressed as N%), crease recovery, tensile strength, elongation at break, air permeability, water permeability
