“…While C–C declines significantly, there is a notable increase in C–O after the APPT. Absorbency of the fabric is vastly enhanced because of the C–O group which attracts water molecules [26,27].…”

The surface of cotton fibre was modified by atmospheric pressure plasma treatment (APPT), using gas as the carrier. Effects of variations in four operational parameters, discharge power, oxygen flow rate, jet-to-substrate distance and speed of the jet movement were examined. Morphology of surface of cotton fabrics was examined by generating Scanning Electron Microscopy (SEM) images. Elementary composition of the surface of the fabric was examined by X-ray Photoelectron Spectroscopy (XPS) and Fourier Transform Infrared Spectroscopy-Attenuated. Total Internal Reflectance (FTIR-ATR) was used for examining functionality of the surface. In this study, we revealed that the operational parameters would physical and chemically after the surface characteristics of the cotton fibre. Physically, cracks and grooves were noted in the cotton fibre surface after APPT. Chemically, the oxygen content in the cotton fibre surface was increased after APPT. When the O/C ratio is taken into consideration, the surface oxidation was a steady effect in applying APPT for treating cotton fibre in this study.

“…Brilliant Yellow and Congo Red were used to print poly(ethylene terephthalate) fabrics using a plasma‐assisted sol‐gel method 17 . The procedure involved five main steps: (a) treatment with an oxygen plasma under vacuum; (b) padding in a sol of 3‐propylaminotriethoxysilane (precursor) and ammonium hydroxide (catalyst) in ethanol and water; (c) air‐drying; (d) post‐treatment either thermally in a convection oven (pad‐dry‐cure method) or by oxygen plasma; and (e) flat screen‐printing of a paste containing the halochromic dye.…”

This paper explores the possibility of dyeing textile fabrics with halochromic dyes. Five different halochromic dyes were tested: bromocresol purple, m‐cresol purple, chlorophenol red, curcumin and bromothymol blue. Preliminary dyeing was carried out on wool, polyacrylonitrile, polyester, polyamide 6.6, cotton and cellulose acetate at 100°C for 40 minutes to evaluate affinity. All the dyes showed good affinity to wool and polyamide 6.6. Cotton required a mordant phase before dyeing. Washing and light fastness were evaluated for the dyed fabrics, as well as colour changes at different pH values. Some fibres displayed good dye fastness and halochromic properties. Bromothymol blue was selected to dye polyamide 6.6 and cotton fabrics. The dyed fabrics displayed good halochromic properties across a pH range of 4 to 10. Cotton fabrics exhibited an immediate colour change; polyamide 6.6 changed colour after several minutes. An industrial dyeing process was performed on natural cellulosic fibres. The results confirmed the possibility of scaling up the process with regard to textile applications of halochromic dyes.

“…Treatment of Polyester fabric with corona discharge irradiation gave better hydrophilicity and water absorption and introduced functional groups on the surface of the material, though temporary (Zahra et al, 2018). Plasma treatment on its part increased surface energy, wettability and roughness of polyester fiber, however, it was costly and had limited industrial application (Zhang et al, 2017;Liu et al, 2017;Neaz et al, 2019;Salem et al, 2017).…”

Purpose The purpose of this paper is to investigate the effects of alkali treatment on adhesion of industrial thermoplastic polyurethane elastomer (TPU)/polyester woven fabric inter-ply hybrid composites. Design/methodology/approach Inter-ply hybrid composites were exposed to varying concentration of sodium hydroxide at different temperature and time and their mechanical properties including differential scanning calorimetry, scanning electron microscope, tensile and peeling strength evaluated to determine optimal treatment parameters. Findings Modified polyester fabrics treated with alkali had higher tensile and peeling strengths. Accordingly, alkali treatment roughened the surface of polyester fabric, decreasing warp and weft densities, thus increasing fiber surface energy. The fabric had the highest peeling strength of 3.23 N/mm at treatment of 25% concentration of sodium hydroxide (NaOH). Short-term exposure to ultraviolet had little effect on interfacial adhesion of alkali-treated conveyor belt. Research limitations/implications Polyester fabric, applied in reinforcing industrial conveyor belts, is never degreased, roughened, sensitized or activated. In this paper, one-step treatment of polyester fabric was performed to increase its adhesion with polyester inter-ply hybrid composites, providing a reference for practical industrial application. Practical implications The method developed in this research is simple and provides a solution to improving the interfacial adhesion of TPU/polyester conveyor belt. Originality/value The novel alkali treatment technology has many applications in the interfacial performance of composite materials.
