“…Wong et al obtained similar results after treating flax fibres in a low‐temperature plasma using oxygen and argon gases . Pectinase enzyme treatment subsequent to atmospheric air or argon plasma surface modification was applied in flax fabric by Karaca et al Results clearly proved that the efficiency of pectinase in improving flax water absorbency can be significantly enhanced by plasma pre‐treatment . Nithya et al investigated the effects of DC air plasma and cellulase enzyme treatments on the hydrophilicity of cotton fabric.…”

Plasma technology applied to textiles is a dry, environmentally‐ and worker‐friendly method to achieve surface alteration without modifying the bulk properties of different materials. In particular, atmospheric non‐thermal plasmas are suited because most textile materials are heat sensitive polymers and applicable in a continuous processes. In the last years plasma technology has become a very active, high growth research field, assuming a great importance among all available material surface modifications in textile industry. The main objective of this review is to provide a critical update on the current state of art relating plasma technologies applied to textile industry.

“…Furthermore, the color of the plasma treated samples was more saturated (positive value for ΔC ab * ) and for the longer treatments it was slightly lighter (positive value for ΔL ab * ). At this point it should be noted that a more significant change in color of the linen fabric (ΔE ab * = 1.6) was observed after plasma treatment with a uniform glow discharge plasma system operating under atmospheric conditions [22].…”

Abstract:In this research, a diffuse coplanar surface barrier discharge (DCSBD) type plasma reactor was used for the surface modification of raw linen fabric. Changes in physical properties and chemical composition of the fiber surface as well as color of the fabric were measured as a function of time of the atmospheric air plasma treatment. Furthermore, ageing of the effects created on the fiber surface by plasma treatment was also characterized in a period of 0-14 days elapsed after the plasma treatment. Significant differences were found between the properties of the raw and plasma treated linen fabrics, including increase of wettability, wickability, surface energy and O/C ratio, and decrease of water contact angle and deterioration of the waxy outer layer of the fibers. Most of the parameters depended on the time of plasma treatment (0-180 s). O/C ratio increased steadily with the increase of duration of the plasma treatment, which was explained by destruction of the waxy surface layer, creation of polar groups and exposure of cellulosic components. Most of the properties tested were found to be stable during two weeks of storage after the plasma treatment, indicating that the surface 'topography' created by plasma remained almost unaltered and the recovery of the etched waxy coverage of the fiber did not occur.

“…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].…”

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.
