“…From data tabulated in Table 2 , the lightness degree varied between 48–63 and 46–66 for wool and polyamide, respectively. Based on that, the color of dyed textiles was fixed and distanced as indicated by Rosu et al [ 40 ]. The values of a* and b* symbolize chromaticity without specific numeric limits.…”

Developing special textiles (for patients in hospitals for example) properties, special antimicrobial and anticancer, was the main objective of the current work. The developed textiles were produced after dyeing by the novel formula of natural (non-environmental toxic) pigments (melanin amended by microbial-AgNPs). Streptomyces torulosus isolate OSh10 with accession number KX753680.1 was selected as a superior producer for brown natural pigment. By optimization processes, some different pigment colors were observed after growing the tested strain on the 3 media. Dextrose and malt extract enhanced the bacteria to produce a reddish-black color. However, glycerol as the main carbon source and NaNO3 and asparagine as a nitrogen source were noted as the best for the production of brown pigment. In another case, starch as a polysaccharide was the best carbon for the production of deep green pigment. Peptone and NaNO3 are the best nitrogen sources for the production of deep green pigment. Microbial-AgNPs were produced by Fusarium oxysporum with a size of 7–21 nm, and the shape was spherical. These nanoparticles were used to produce pigments-nanocomposite to improve their promising properties. The antimicrobial of nanoparticles and textiles dyeing by nanocomposites was recorded against multidrug-resistant pathogens. The new nanocomposite improved pigments' dyeing action and textile properties. The produced textiles had anticancer activity against skin cancer cells with non-cytotoxicity detectable action against normal skin cells. The obtained results indicate to application of these textiles in hospital patients’ clothes.

“…As the unit of cellulose has groups that absorb heat, the internal, and external chromophoric impurities or additives are able to induce its thermal degradation [61][62][63] . The thermal-degradation processes involved in cellulose are main chain scission, de-hydroxylation, dehydromethylation, and dehydrogenation, which resulted in to form of several free radicals that cause the degradation and yellowing of cellulose [64][65][66][67] .…”

In the present work, the composite cross-linked were used to consolidate the dyed paper manuscripts. Nanocomposites of mesoporous silica nanoparticle (MPSNP)/polyvinyl alcohol (PVA) and cellulose nanofiber (CNF)/PVA, which have never been used before, have been evaluated for the consolidation process of the dyed paper manuscripts with madder extract. Three concentrations 1%, 3%, and 5% have been prepared. Analysis and investigation methods like scanning electron microscope (SEM), transmission electron microscope (TEM), dynamic light scattering analysis (DLS), X-Ray diffraction Analysis (XRD), atomic force microscope (AFM), Fourier transform infrared spectroscopy (FTIR) and total color difference (ΔE) by spectrophotometer have been used in order to characterize the prepared nano-sized composites and evaluate the treated dyed paper samples before and after the aging process. The results of surface morphology by SEM revealed the effectiveness of MPSNP/PVA core–shell nanocomposite at 5% in the consolidation process, where the improvement of properties of the aged dyed paper samples. The fibers of the treated paper became strong and appeared clearly. The result of ΔE measurements showed that the treated sample with MPSNP/PVA nanocomposite at 5% gave the lowest ΔE (5.22), while, the treated sample with CNF/PVA nanocomposite at 5% gave the highest ΔE value (11.66). Mechanical measurements (tensile strength and elongation) revealed the efficiency of MPSNP/PVA nanocomposite at 5% in the treatment of the aged dyed paper samples. The treated sample with the mentioned material gave tensile strength and elongation values of 84.8 N/nm2 and 1.736%, respectively. In contrast, the treated sample with CNF/PVA nanocomposite at 1% gave the lowest tensile strength and elongation values 38.2 N/nm2, and 1.166%, respectively. FTIR analysis revealed an increase was noticed in the CH2 stretching band (refers to the crystallinity of cellulose), where the intensity of the treated sample with MPSNP/PVA nanocomposite was at a 5% increase compared to the control sample. The FTIR results supported the results of mechanical measurements. The intensity of the CH2 stretching band, which refers to the crystallinity index of cellulose, was increased with the use of MPSNP/PVA nanocomposite at 3% and 5%, which explains the improvement in mechanical properties. This may be due to the nano-mineral particles, which improve the mechanical properties. Additionally, they reduce the effect of accelerated thermal aging on the cellulosic fibers and give them stability. The detailed analysis of analytical methods used for evaluation revealed the novelty of MPSNP/PVA nanocomposite, especially at 5%. It has a potential role in strengthening and improving different properties of the dyed paper manuscripts with madder extract.

“…Out of 10, 000 synthetic dyes used for textile colouration annually by the textile industries, 50% are reactive dyes [13]. This presupposes that, most textiles released into the textile market one way or the other have some traces of reactive dyes in the colour they exhibit.…”

“…22 8 × 105 tons every year [10][11][12]. Buttressing this, Rosu et al [13] established that, 10,000 synthetic dyes are made commercially available annually for the textile colouration industries at different stages. Although, other chemical classes of synthetic dyes including oxazine, azine, triphenylmethane, nitro, xanthene, anthraquinone and indigoid have had a significant impact on the industry, the most abundant class of synthetic dyes is the azo [6].…”

The application of dyes in textile colouration has existed for centuries. Dyes are obtained from both natural and synthetic sources. Synthetic dyes are manufactured from chemical compounds and have been placed on a high pedestal in the textile industry due to their improved colour fastness, varied range of pigments and easy application as compared to natural dyes. However, they have been identified to be harmful to the environment and human health by researchers. When effluent containing harmful chemicals like sodium sulphide is discharged into the environment improperly, they cause a lot of diseases and hinder smooth air flow. With current submissions made by researchers on synthetic dyes application as a backbone, this review throws more light on the dangers and benefits involved in the use of synthetic dyes in the textile industry. It also touches on waste management as far as textile dyes are concerned. The application of synthetic dyes, precisely vat, reactive and sulphur dyes are highlighted in the study. With the purpose of addressing appropriate means of curbing undesired hazards caused by textile wastes water, several technological approaches to effluent treatment such as Physical, Chemical and Biological are brought to light in the study. The study recommends the adaptation of waste management principles such as the 5R hierarchy to curb environmental harm caused by synthetic dye effluents.
