Surface modification and improvements of wicking properties and dyeability of grey jute-cotton blended fabrics using low-pressure glow discharge air plasma

Abstract

Herein, we reported the improvements of wicking properties and dyeability of the jute-cotton blended (40:60) fabrics due to the effect of low-pressure glow discharge (LPGD) air plasma under selected exposure times. The microscopic features, functional groups, wettability, contact angles, wetting area, wicking rates, and reflectance values of the jute-cotton blended fabrics were analyzed using numerous experimental techniques. The scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) techniques were used to investigate the morphological and compositional modifications of plasma-treated jute blended cotton fabrics. The compositional analysis confirmed various functional groups such as –OH, C–O, and COO − on the surface of jute blended cotton fabrics. The average pore radii and diffusion coefficient were calculated by using the modified Lucas-Washburn equation. The plasma-treated fabrics were shown to have an average pore radius of 0.93, 1.46, 2.26, and 4.8 μm under treatment time of 5,10,15, and 20 min. Nearly 50% reduction of contact angle was observed after a plasma treatment time of 20 min. The absorption to scattered ratio, K/S (determined using Kubel-Munk model) of the colored fabrics with 5 min pre-treated plasma was 6.47, although it was raised up to 8.51 after 20 min of pre-treatment. A reactive dye, Bezaktiv Red S–3B, was used for the dyeability test, and our findings showed that the dyeability and the wettability of the fabric were substantially enhanced with the treatment time of LPGD air plasma. Among the samples, only 10 min plasma pre-treated colored fabric exhibited a color difference of less than one compared to the standard one.

Fabrication of the PES Membrane Embedded with Plasma-Modified Zeolite at Different O2 Pressures

“…It is believed that plasma treatment is a suitable method for modifying the surface properties of various materials by introducing the hydrophilic functional groups, which is also confirmed by FTIR results obtained in this study. However, considering the XRD and SEM characterizations where considerable changes were not observed in the treated and untreated samples, we validate the hypothesis reported in studies regarding the plasma treatment, which has no effect on the bulk properties of materials. − …”

Current Development and Future Perspective on Natural Jute Fibers and Their Biocomposites

“…In general, chemical modification and bleaching are applied to the jute fiber to make it softer. Research is being carried out on jute-cotton blended textiles to bring certain functional properties by applying different surface treatments for instance atmospheric plasma treatment for improving wicking and dyeability properties whereas chitosan treatment for incorporating antibacterial property [ 135 , 136 ]. Natural fibers like jute can produce less ecological, water and CO 2 footprints [ 137 ], which will have an overall positive environmental impact.…”

Surface modification of jute-cotton union fabric using TiO2 and ZnO nanoparticles for multifunctional properties

“…Jute-cotton union fabric, proportional blend of jute and cotton fibers, is a cellulosic fabric that contains hydroxyl group (OH), which makes the fabric surface hydrophilic [ 1 ]. Therefore, the fabric intends to be wetted quickly by water and other liquids.…”
