“…Weight loss in this study shows a variation of between 0.5% -1.2%. However, with increasing time treatment, weight loss is Other studies show that plasma treatments reduce weight in cotton fibers between 1%-6% 35 and 0.5% 36 , grey cotton between1.5%-4% 37 and for other fibers such as silk after nitrogen plasma treatment between 9%-21% 38 . Same condition happens for synthetic polymers like polyethylene 39 , polypropylene 19 , and PET films 40 .…”

In this paper, cotton fabrics were washed, bleached and then treated with low-temperature plasma of nitrogen then dyed with direct dyes. Some properties of the samples such as zeta potential, weight loss, crystal intensity, dyeability and washing fastness were investigated. The relative color strength and reflection properties of dyed samples were measured by using reflective spectrophotometry. The morphological changes of cotton samples after nitrogen plasma were studied by scanning electron microscope. Also chemical changes and zeta potential of samples have been investigated by using Fourier Transform Infrared Spectroscopy (FTIR) and zeta sizer respectively. The results show that zeta potential of cotton fabrics influenced by plasma treatment and also dye, plasma treatment cause to improve color strength near 20%.

“…The existence of carboxylate group can be confirmed by the presence of two peaks at 1650cm -1 and 1420 cm -1 for asymmetric and symmetric stretching of COO -ion respectively. However when the fabrics are treated with cellulase enzyme the concentration of carbonyl group increases [13]. Furthermore, when the fabrics are treated with oxygen plasma and enzyme combination, it is observed that for EP treated fabrics the concentration of carbonyl group increases, whereas for PE treated fabrics the concentration of carbonyl group decreases.…”

“…can be improved by enzymatic hydrolysis. Moreover, these properties can be further enhanced by the combination of the above two treatments as reported by several authors [11,13,16,17]. Such improvement of fabric property can be exploited for the enhancement of antimicrobial efficacy [18].…”

“…The reason could be, for PE treated fabrics, when the fabrics are first exposed to oxygen plasma, more carboxylate groups (COO -) are formed, further, when it is treated with enzyme there is no drastic increase in the carbonyl group due to the enzyme hydrolysis, since the carboxylate groups are more stable. Table. 1 Infrared absorption frequencies of untreated and treated cotton fabrics (cellulose) For EP treated fabrics, the intensity of carbonyl group increases significantly due to enzyme hydrolysis and subsequent oxidation [13] Asym.out-of-phase ring stretch: C 1 -O-C 4 ;β glucosidic bond enzyme treated fabrics are exposed to oxygen plasma, there is no significant increase in COO -groups which in turn does not affect the hydrophilicity of the fabrics considerably. Thus the ATR FTIR results provide an insight into the formation of COO -groups in oxygen plasma and PE treated fabrics which also increases the hydrophilicity similar to EP treated fabrics.…”

Oxygen plasma treatment and/or cellulase enzyme treatment was carried to improve the surface properties of cotton fabrics for medical applications. The influence of Plasma (P), enzyme (E), plasma preceded by enzyme (EP) and enzyme preceded by plasma (PE) treatments on hydrophilicity of the cotton fabrics was studied using standard wicking test. The physical and chemical modification due to plasma and enzymatic treatments were analyzed using SEM and ATR-FTIR spectroscopy. The FTIR results revealed that the oxygen plasma has modified the surface chemically by introducing oxygen containing groups (C=O, C-O, COO -) onto the fabric surface and enzyme have hydrolyzed the cellulose molecule. The physical etching of the fabric surface was observed in SEM photographs and weight loss measurements. The modified fabrics were given antimicrobial finish and tested for its antimicrobial activity against 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.
