“…Further investigations revealed that all the samples within the same region demonstrated the isotropic behavior with higher bending groups -CH 2 , and -CH 3 (see Figure 4(b)). Our results are in good agreement with earlier reports [51,52,53,54]. Figure 5(a) and (b) show the UV visible spectra of five dye samples with water, and ethanol solvent, respectively.…”

In this paper, we reported the extraction process of five different flowering plants utilizing different dye extraction methods and solvents (ethanol and water) to choose the best dye removal process. The FTIR spectra revealed the presence of several clear functional groups for all five natural dyes. The analytical studies such as UV spectroscopy, column chromatography, and vacuum evaporation were performed to isolate the dyes from their solutions. The UV-Vis studies on the pigments of flower extracts indicated broad absorption peaks in the visible region including clear bandgaps. Among the studied pigments, Alternanthera ficoidea showed the lowest direct bandgap of 1.69 eV and an Urbach energy value of 6.33 meV. The dye extraction yield rate improvement was extended from 11.7 to 24.7% (water solvent) and 11.3-32.4% (ethanol solvent). Throughout the studies, it was observed that ethanol produced a better extraction for organic dyes than water as a solvent. Aging studies revealed that all the dyes at the room temperature showed better stability with minor changes in the observed optical parameters in oxygen-rich conditions; however, these parameters have shown significant variations at a 60 C temperature.

The Alphabet Reform painting which shows Ataturk teaching the new alphabet is important for the history of the Republic of Turkey. This painting was made by Nazmi Ziya GÜRAN in 1933. The painting is now maintained by the Ministry of Interior. In this work, the Alphabet Reform painting was analyzed for characterization and restoration purposes. The fabric of the canvas, pigments (organic-inorganic) and the binder of paint were characterized by Fourier Transform infrared spectroscopy-attenuated total reflectance (ATR-FTIR), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) and highperformance liquid chromatography-coupled with diode array detection (HPLC-DAD) analysis methods. The CIEL*a*b* color parameters of the paint were determined by color measurement spectrophotometer. According to the results, the canvas was found to be of fibers of vegetable origin and the binders were determined to be linseed oil and dammar varnish. Red alizarin (madder lake organic pigment) and dark blue ultramarine pigments were detected as the organic pigments while CdS (yellow), Pb red (flesh color), PbCO3 (white), ZnO (white), BaSO4 (white), FeO (brown) and Cr2O3 (green color) were detected as the inorganic ones.

“…One example of a type of fibre identification study that benefits from combining all of the abovementioned fibre features is the case of separating flax and nettle fibres: they share the same fibrillar orientation (Bergfjord and Holst 2010), but have different and distinctive cross-sectional shapes (Nayak et al 2012;Suomela et al 2018;Lanzilao et al 2016).…”

Wide-angle X-ray scattering studies on contemporary and ancient bast fibres used in textiles – ultrastructural studies on stinging nettle

Stinging nettle (Urtica dioica) is a potential source material for industrial applications. However, systematic research on the ultrastructural properties of nettle fibres is lacking. Determining the ultrastructure of nettle and the other bast fibres also provides new insights into the studies of archaeological fibres and their usage. In this study, the nanostructure of modern and ancient nettle samples was studied using wide-angle X-ray scattering (WAXS) and compared to other bast fibres. The culturo-historical fibre samples consisted of nettle, flax, and hemp from White Karelian textiles collected 1894 as well as of 800–900-year-old archaeological textile fragments from Ravattula Ristimäki burial site, Finland. Using WAXS, the average cellulose crystallite widths, relative crystallinities and orientational order (including microfibril angle for the modern fibres) were determined and compared. The results also revealed the suitability of the WAXS analysis for fibre identification. The crystallite widths were of the similar size for all modern fibres (3.4–4.8 nm). Subtle differences in the relative crystallinities in descending order (from flax to nettle, and finally hemp) were observed. Also, subtle differences in the mean MFAs were observed (10 ± 1° for flax, 12 ± 1° for nettle, and 14 ± 1° for hemp). For the culturo-historical fibres, the values for crystallite widths and relative crystallinities were larger compared to the corresponding modern references. In addition, features due to the presence of non-cellulosic, crystalline substances (e.g., calcium oxalates) were detected in the WAXS patterns of all the modern nettle fibres. These features could potentially be used as a tool for identification purposes. Graphical abstract
