“…SEM images (Fig. 1 ) confirmed the change of morphology and increased roughness of PA surface, as expected after plasma treatment 25 . Compared to the smoother surface on untreated samples, micro-etched areas were visible on all treated samples due to the bombardment of gaseous ions by the plasma process.…”

“…Among these parameters, the used gas is the main factor determining which functional group would be introduced on the PA surface. Oxygen and nitrogen are common reactive gasses used for this purpose 25 . Hence, the effects of these two gasses on PA fabric to influence adhesion and activity of printed tyrosinase were studied by keeping other plasma parameters constant.…”

“…1 ) and XPS results (Table 1 ) confirmed the increment of oxygen and nitrogen species after respective plasma processes, along with the introduction of hydroxyl and carboxyl groups. Nitrogen gas containing treatments showed relatively higher activity which might have been aided by better adsorption kinetics between plasma-enhanced amide groups on fabric 25 and amino groups on enzyme protein molecules 42 .…”

Tyrosinase enzyme was digitally printed on plasma pretreated polyamide-6,6 fabric using several sustainable technologies. Ink containing carboxymethyl cellulose was found to be the most suitable viscosity modifier for this enzyme. Before and after being deposited on the fabric surface, the printed inks retained enzyme activity of 69% and 60%, respectively, compared to activity prior printing process. A good number of the printed enzyme was found to be strongly adsorbed on the fabric surface even after several rinsing cycles due to surface activation by plasma treatment. Rinsed out fabrics retained a maximum activity of 34% resulting from the well-adsorbed enzymes. The activity of tyrosinase on printed fabrics was more stable than ink solution for at least 60 days. Effects of pH, temperature and enzyme kinetics on ink solution and printed fabrics were assessed. Tyrosinase printed synthetic fabrics can be utilized for a range of applications from biosensing and wastewater treatment to cultural heritage works.

“…For example, lamination and impregnation with substances demonstrating antimicrobial activity have both been used to create a sterile barrier [199,200]. Plasma modification can be used to impart hydrophilicity to fabrics [201], whilst some of the more-recent treatments involve those that may allow the mounting of biosensors within the fabric, technology which is enabling advancement in the field of smart textiles [202,203]. In one study, the preparation of organic electrochemical transistors on nylon fibres demonstrated stable performance during bending tests due to the introduction of a metal/ conductive polymer multilayer electrode onto the fibre.…”

Surface functionalization of greige cotton knitted fabric through plasma and cationization for dyeing with reactive and acid dyes

et al. 2021

Dyeing cotton fabrics with anionic dyes produces high e uent loads and requires a considerable amount of water and energy due to the electrostatic repulsion with cellulose. Therefore, several approaches have been researched to increase the e cacy of cotton dyeing. One is the cationization, which adds cationic sites to the cellulose. Another is the treatment of the cotton surface with plasma. In this paper, the combination of both techniques was investigated. Two commercially available cationic agents were used: 3-chloro-2-hydroxypropyl trimethyl ammonium chloride (CHPTAC) and poly[bis(2-chloroethyl) etheralt-1,3-bis[3-(dimethylamino)propyl]urea] quaternized, a novel cationic agent also known as Polyquaternium2 (P42). The plasma treatment was performed using a dielectric barrier discharge atmospheric plasma facility, helium was used as seed gas and 1.5 % of oxygen was injected. The cationization and plasma treatment were performed on greige cotton fabric, an innovative and sustainable approach that eliminates conventional scouring and bleaching processes. The cationic and plasma treated samples were dyed using Reactive Red 195 and Acid Blue 260 dyes. The effect of the treatments was evaluated by different characterization techniques such as X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM). The plasma treatment slightly increased the light fastness for some samples, but the cationization tends to prevail over the plasma treatment. The best results were attributed to the samples pretreated by CHPTAC, which presented the highest K/S and lowest unlevelness for samples dyed with reactive and acid dyes. CHPTAC is the most common cationic agent for textiles, but its industrial use is limited due to safety criticisms. The combination between plasma and P42 resulted in the same color strength as the conventional reactive dyeing. Therefore, this approach offers a safer alternative to the conventional cationization process.
