“…Furthermore, the peaks at the wavenumbers of 1440, 1231, 1158, and 1062 cm −1 were responsible for the C–H bending, the C–C and C–N stretches in Amide III, the C–N stretch in tyrosine, and the C–C stretch, respectively. 50 It was assumed that the anthraquinone-based dye had the similar vibrational spectral pattern with silk fiber as the silk was dyed, proposing the firm intermolecular bonds between the aromatic compounds of the dye and the functional groups of silk, and thus dyeing with the R. cordifolia extract had no effect on the silk structure. 51 In parallel, Figure 2(d) reflects that the mentioned peaks were also found in the FTIR spectra of the Rubi-D-C and Rubi-D-Al samples.…”

“…52,53 Moreover, the peaks at 695 and 640 cm −1 in the spectrum of the Rubi-D-Al sample became moderately sharper compared to those of the Rubi-D sample, possibly owing to the Al-N and Al-O bonds, respectively. 50…”

As shown in Figure 3 (a), pristine silk possesses a smooth and bright fiber surface without any clustering, irregularity, or imperfection.…”

Natural dyes have attained the interest of scientists over the last decade due to their functional activities in addition to their primary role of color impartation on textile materials. This study is the first report on the functionalization of silk with antimicrobial and ultraviolet protective properties using a dye extract from the roots of Rubia cordifolia L. in conjunction with chitosan as a bio-mordant. Alum mordant was also used in the dyeing process alongside chitosan for comparison purposes. Fourier transform infrared spectroscopy and ultraviolet-visible spectroscopy were utilized to determine the anthraquinone-based components of the dye extract. Furthermore, the structure and surface morphology of silk fibers before and after dyeing were investigated. The dyed silk samples exhibited good fastness against washing, rubbing, and lighting. The chitosan mordanted-dyed silk presented remarkable antimicrobial properties with maximum inhibitions of 96.71% and 99.08% against Escherichia coli and Staphylococcus aureus, respectively, and only 2.3% spore germination of white mold ( Aspergillus spp.). Likewise, an excellent ultraviolet protection factor was achieved in the chitosan modified-dyed silk. The findings of this study demonstrated the potential of the Rubia cordifolia L. extract as a functional dye, as well as the advanced properties of chitosan in increasing the fastness and functional performance for the dyed silk compared to alum mordant.

“…The basic color of a dyed yarn is determined mainly by the nature of the dyes employed. However, variations in color may be obtained during the dyeing process mainly through changes in mordants and adjuvants, 107‐109 pH and temperature of the dyeing bath, 110 and the natural color of the fleece employed 17 . The DDCD of yarns of different colors will be discussed in terms of the potential number of main dyes employed and their visible spectra, the differential binding of dyes to mordants, and the use of fleece with different natural pigmentation.…”

Few sources of red (anthraquinoids) and blue (indigoids) dyes were used in pre‐Hispanic textiles from different cultures, periods, and areas in the South‐Central Andes. Yellow dyes have been shown to be mainly flavonoids. Since flavonoids exhibit wide color variations, ample distribution dependent on biogeographical region, and species‐specific patterns, color variation in yellow‐dyed textiles and sources of yellow dyes are predicted to be higher in relation to red‐ and blue‐colored textiles. The study of textile colors, in particular the comparison between yellow and other colors, should shed light on the relationship of people with the environment and on the processes of selection of sources of raw materials for textiles. Colorimetric data in the CIELAB three‐dimensional space were obtained of yarns sampled from pre‐Hispanic textiles from San Pedro de Atacama (37 textiles, 79 yarns of different colors) and Quillagua (41 textiles, 95 yarns of different colors), two archeological areas in Northern Chile sustaining different plant communities. The textiles were assigned to different styles (hence to different biogeographical regions). The results showed that the degree of dispersion of colorimetric data was larger in red than in blue yarns, and did not differ between any other pair of colors, and that the degree of dispersion of colorimetric data of yarns from textiles of different styles differed significantly within yellow yarns but not within yarns of other colors. These results are discussed in terms of the nature, variety, and sources of the dyes involved and reveal the use of a limited number of yellow dyes in Northern Chile.

“…The existence of -OH or -C=O groups in the structure is necessary to obtain the metal-flavonoid complex. In this sense, the flavonoid can generate the complex with positively charged metals [38].…”

he skin of the onion plant is a natural waste product. In this context, it is possible to evaluate their use in natural dyeing (cotton, wool, silk, etc.) and in lake pigment production by extracting the dyestuffs in these wastes. The skin that forms this outermost part contains some flavonoid (quercetin, etc.) and anthocyanidin (pelargonidin, etc.) natural dyestuffs. Quercetin glycosides are flavonoids liable for the majority of the flavonols in the plant. The amount of quercetin may increase from the inner part of the onion plant to the outer part. It is known that onion skin has been used in wool dyeing from past to present. It has traditionally been used in carpets and rugs. Onion skin was used in Anatolia, Turkey, where carpets and rugs were produced.
