摘要：Oxygen plasma treatment and/or cellulase enzyme treatment was carried to improve the surfaceproperties of cotton fabrics for medical applications. The influence of Plasma (P), enzyme (E), plasma preceded byenzyme (EP) and enzyme preceded by plasma (PE) treatments on hydrophilicity of the cotton fabrics was studied usingstandard wicking test. The physical and chemical modification due to plasma and enzymatic treatments were analyzedusing SEM and ATR-FTIR spectroscopy. The FTIR results revealed that the oxygen plasma has modified the surfacechemically by introducing oxygen containing groups (C=O, C-O, COO-) onto the fabric surface and enzyme havehydrolyzed the cellulose molecule. The physical etching of the fabric surface was observed in SEM photographs andweight loss measurements. The modified fabrics were given antimicrobial finish and tested for its antimicrobial activityagainst S.aureus and E.coli using AATCC 100 test. The EP treated fabric was found to have 100% bacterial reduction.The wash durability of the finished fabrics was also assessed and the results are discussed.
