“…30,31 Low temperature plasma treatment as a physicochemical method, could be a good alternative for eliminating these negative effects by modifying the surface of the material before the finishing applications, especially dyeing process. 27,32 Hibiscus sabdariffa, also known as roselle, with red or pale yellow inflated edible calyces, is an ideal crop for developing countries as it is relatively easy to grow, can be grown as part of multi-cropping systems and can be used as food and fibre. The red pigmentation of the calyces is due to the high concentration of anthocyanins.…”

In the colouring processes of textile products, more environmentally friendly chemicals and finishing methods should be used instead of conventional ones that harm the environment every day, so that alternative realistic ways to protect nature, both academically and industrially, could be possible. Due to some inconveniences caused by synthetic dyes that are widely used today, in this study, ultrasonic dyeing of wool fabric with Hibiscus sabdariffa was carried out after environmental‐friendly air vacuum plasma application which increased the absorption of the dyes into the textile material. According to the performance results, colour strengths of the wool fabrics were increased significantly. Surface morphology analysis was carried out and etching effects of air vacuum plasma treatment were clearly seen on the micrographs of the treated wool fabrics. An environmental‐friendly green process was achieved through this study and it was concluded that vacuum air plasma treatment could be an alternative green‐process as a pretreatment to increase the dye up‐take of natural dyeing treatment. Moreover, in this study, a feed‐forward neural network (FFNN) model was presented and used for predicting the dyeing properties (L, a, b and K/S) of samples. The experimental results showed that the presented model achieves the regression values greater than 0.9 for all dyeing properties. Consequently, it was considered that the proposed FFNN was successfully modelled and could be efficiently utilised for dyeing characteristics of wool fabrics dyed with natural dye extracted from Hibiscus sabdariffa.

“…Modifying the wool fibre surface leads to an improvement in the hydrophilicity and dyeability of these fibres 15 . Low‐temperature plasma treatment has the advantages of energy saving, environmental friendliness and high efficiency compared with traditional modification methods 16 . Plasma treatment results in removal of the hydrophobic surface layer and causes etching on the surfaces of wool fibres.…”

In this study, the ecological dyeing process of wool fabrics was investigated. Wool fabric samples were treated with atmospheric pressure plasma‐jet and corona discharge plasma to modify the surface to make the process sustainable and greener. The samples were dyed with the aqueous extract procured from the powdered roots of Rubia tinctorum L. (madder) using the ultrasonic‐assisted method. Scanning electron microscopy and Fourier Transform–infrared analysis were performed to investigate the effect of plasma treatment on the physical and chemical properties of wool fibres. The effects of plasma treatment type, plasma treatment parameters and the duration of dyeing on colorimetric and fastness properties were investigated. The etching of the wool fibre surface and roughness after plasma treatment were proven with scanning electron microscopy images. The Fourier Transform–infrared spectra showed that no significant differences in the functional groups of wool fibre occurred after plasma treatment. The experimental results proved that plasma treatment parameters and dyeing time had an effect on the colorimetric and fastness properties of the samples. Furthermore, an artificial neural network model was proposed for estimating the dyeing properties of wool fabrics, namely, L, a, b, K/S, colour change, rubbing fastness (dry) and rubbing fastness (wet). The experimental results show that the proposed model achieves regression values greater than 0.97 for all dyeing properties. The proposed model is successful and can be efficiently used for estimating the dyeing characteristics of wool fabrics.

“…Many studies on the changes of wool surface properties have also been carried out. Mendhe and Arolkar, 13 Haji and Shoushtari, 14 Gaidau et al, 15 Barani and Haji, 16 Liu et al, 17 Demir et al, 18 Ferri et al 19 studied the changes in the surface chemistry and morphology of wool after the plasma treatment. Since the effect of plasma is limited to the depth of several tens of nanometers below the fiber surface, [20][21][22] it does little harm to the inherent properties of wool fabric, so the application of plasma to modify wool fabric has a broad development prospect.…”

The oxygen low-temperature plasma (LTP) treatment on knitted woolen fabric was carried out to investigate the changes of shrinkage resistance, bursting strength and moisture absorption of knitted woolen fabric after treatment. In addition, the effects of different levels of exposure time, treatment power and gas flow rate on the change of felting rate, bursting strength and moisture absorption of knitted woolen fabric in the process of LTP were investigated. The results show that LTP treatment can improve the anti-felt, bursting strength, moisture absorption of knitted woolen fabric. According to the analysis of variance, in the process of LTP treatment, the exposure time is the primary factor that affects the degree of change in the hygroscopicity of knitted woolen fabric, and treatment power is the main factor that affects the degree of change in the shrinkage resistance of knitted woolen fabric. Finally, under the experimental conditions, the best treatment process of knitted woolen fabric by oxygen low-temperature plasma is 20 min, 150 sccm and 400 w.
