Comparative antibacterial properties of glyoxal and glyoxal and chitosan treated cotton fabrics

Antibacterial comparisons of cotton fabrics treated with glyoxal and with a mixture of glyoxal and chitosan were made. Fabrics treated with glyoxal alone had slightly better antibacterial properties than when treated with a mixture of glyoxal and chitosan. Based on average percent bacterial reduction, the chitosan did not improve antibacterial ability of the fabrics treated with mixture of glyoxal and chitosan. in addition, fabrics treated with the mixture of glyoxal and chitosan had a yellowing problem when the fabrics were cured at high temperature.
