“…This signifies the superior reactivity of oxygen species present in air plasma compared to nitrogen species. 59 The analysis of untreated and plasma-treated samples gave O/C ratios of 0.73 and 0.81, respectively, which clearly indicates that the O/C ratio increases after plasma treatment. This increase in the oxygen content on the fabric surface suggests that the bombardment of plasma-activated species leads to incorporation of oxygen-containing functional groups on the cellulosic fibers, thereby increasing the concentration of oxygen on the surface of banana fabric.…”

This paper focuses on the investigation of the antimicrobial activity of banana fabric treated with dielectric barrier discharge (DBD) plasma. The fabric was exposed to air plasma for varying treatment times of 1–5 min followed by coating with green tea ( Camellia sinensis ) and tulsi ( Ocimum sanctum ) leaf extracts at five different concentrations. The treated fabric was evaluated in terms of surface wettability by a range of tests like wet-out time analysis, hydrophilicity test, and contact angle measurements. The functional groups formed on the treated fabric were analyzed by attenuated total reflectance–Fourier transform infrared (ATR-FTIR) spectroscopy. The surface morphology was studied using atomic force microscopy (AFM) and scanning electron microscopy (SEM), and the surface chemistry was studied using X-ray photoelectron spectroscopy (XPS). The FTIR and XPS analysis results indicate that the plasma-treated fabric was found to have a higher concentration of polar groups (−COOH, −OH, −C=O) that has improved surface hydrophilicity and functionality. The antimicrobial activity of the treated fabric surface was determined both qualitatively and quantitatively by the agar plate method and modified Hoenstein test, against Gram-positive ( Staphylococcus aureus ) and Gram-negative ( Escherichia coli ) bacteria. An improvement in the antimicrobial property was observed in plasma-treated banana fabric coated with natural extracts even after four washing cycles. This study suggests that air DBD plasma treatment followed by the absorption of tea/tulsi leaf extracts can serve as a better tool for developing natural antimicrobial textiles, which could serve the purpose in medical and healthcare sectors concerning recent times. It has eventually led to better absorption of plant extracts, thereby increasing their antimicrobial activity.

“…The AFM 3D representation of untreated and the cellulase enzyme treated fibers are shown in Figure 3, along with the calculated values of average roughness (Ra) and root‐mean‐square roughness (RMS) listed in Table 6. Lotus fiber is a cellulosic fabric with lignin and pectin and other non‐cellulosic impurities associated with amorphous cellulose at surface of the fibers [12] . The cellulase enzyme treatment can remove amorphous cellulose and other surface impurities, thus the enzymatically treated lotus fabric surface (Figure 3b) exhibited enhanced roughness, also as precented in the tabulated values.…”

“…It is reported by several researchers that lotus fibers chiefly consist of cellulose and other components are hemicellulose, and lignin. As seen from Figure 1, the ATR‐FTIR spectrum of lotus fabric represents a set of peaks similar to the cellulose [12,21] . The obtained spectrum compared with IR spectrum of cellulose and peaks recognized accordingly.…”

“…As seen from Figure 1, the ATR-FTIR spectrum of lotus fabric represents a set of peaks similar to the cellulose. [12,21] The obtained spectrum compared with IR spectrum of cellulose and peaks recognized accordingly. The broad peak from 2900 cm À 1 to 3400 cm À 1 is attributed to the cellulose I hydroxyl group forming the interand intra-molecular bonding of hydrogen.…”

“…These stem fibres have also been widely used as porous and composite materials [14][15]. Garment produced from lotus fibre has unique properties such as good breathable, wrinkle-free property, UV resistance property, good moisture absorption, air permeability, soft and comfort properties, bio-degradable, eco-friendly, organic and gave silk-linen combination feel [16]. Nomark lotus shirt is a popular brand that sells Men"s shirt made from lotus fibre.…”

Presently, sustainability became a key mantra in all the industries across the world, especially the textile sector as it is one of the largest industries in the world. In textile science, natural fibres have a big role in a sustainable environment-friendly future and became a significant topic to exploit a new natural resource which is green and environment-friendly. Considering this, fibres from various sources were explored by many researchers for its potentialities in improving the quality of life around the world. Aloe vera, banana, sisal, hemp, jute, bamboo, milk fibre, corn, soya, groundnut shell, arecanut, coffee bean waste, lyocell and eucalyptus were few among them. Each year, more synthetic fibres and high energy-consuming products are being replaced by natural-fiber-based products. Additionally, natural fibres have been used not only for clothing but also for technical applications such as composite materials, building materials, filtration and insulation materials. The reason for this trend is not only due to increase environmental awareness but also because of its excellent properties, such as lightweight, strength, low costs and simple sourcing. Meanwhile,waste utilization became one of the important and challengeable jobs around the world. The Textile industry has obtained many fibres from bioresource waste as an important step toward sustainable development. As for example, Pinafibre is a minor fibre obtained from waste pineapple leaves. The study attempted to review some of the selected new sustainable fibres from waste materials and their application in textiles.
