“…From Table 4, it is clear that treating with chitosan generally could decrease the values of L* meaning that the color of the treated fabrics got darker than the untreated fabrics. The same observation was also obtained by Ali, El-Khatib, & EL-Mohamedy (2019).…”

“…This finding is also consistent with the other findings. Ali, El-Khatib, & EL-Mohamedy (2019) showed that the color strength of pretreated wool fibers with nanochitosan and chitosan and dyed with saffron red and yellow mixture has high value of color strength than untreated wool fibers. The same observation was also found by Yadav, Singh, Kaur, & Sahu (2019).…”

Application of natural dyes in textile coloring has been widely used because it is more environmentally friendly than synthetic dyes and is able to produce various colors from one natural dye. In this study, cotton fabric was treated with chitosan at different concentrations (0, 0.25%, 0.5%, and 1%) to determine its effect on the color fastness using mango leaves extract as natural dyes. Fastness to ironing, washing and sun drying of chitosan-treated samples were measured and compared with untreated samples. The effect of using different types of mordants (ferrous sulphate and alum) was also investigated. Coloring of the dyed fabric was evaluated in terms of color parameters (L* a* b*) and the dye absorption was evaluated using K/S values. The results showed that the color fastness to wet and dry rubbing at each concentrations of chitosan and different types of mordants were good. However, the fabric processed with ferrous sulphate has a lower value of color fastness to ironing than that with alum. The color fastness to washing showed quite good results. The color fastness to sun drying showed that the cotton fabric with or without pre-treatment with chitosan showed good results. However, the value of fabric processed with ferrous sulphate showed very good values compared to alum. High values of K/S were obtained on fabrics pre-treated with chitosan for all types of mordants. Fabric processed with alum showed high color brightness.

“…[3,12,46,69,70] It is known to be the costliest plant grown anywhere in the world. [46,71,72] Saffron flowers are light purple with reddish and yellowish thread derived from the plant's dried stigmas and are described as a flavour with a distinctive natural colourant and have also been utilized in the cosmetics industry [12,71,73,74] The image of the saffron plant was showed in Fig. 16.…”

N ATURAL dyes are colours generated from natural sources. Many chemical processes using petrochemical-based dye intermediates are used in the creation of synthetic dyes, which use a lot of energy and release harmful toxic substances into the environment. So they have been substituted with natural ones that have many advantages, and despite these advantages, natural dyes have some serious disadvantages because of the technical and environmental challenges related to the production and use of natural dyes. To extract dye from its source, they must use a specialized process. The following are some ways of extracting natural colours from their sources: Aqueous extraction, Solvent extraction, Acid and alkali extraction, Supercritical fluid extraction, Ultrasound-assisted extraction, Enzyme assisted extraction. Many bioactive compounds are found naturally in plants. Plant-derived dyes such as red onion peel, Psidium guajava leaves, saffron flower, banana peel, and Ficus leaves are extensively used to colour textiles in the textile and fashion industries.

“…Environmentally friendly treatments such as biopolymers are used instead of chemical treatments to remove chemical pollutants and their residues resulting from chemical processes [15]. The natural polysaccharide was applied to treat natural fibers [cotton, wool, silk] to improve their properties because natural textiles especially those made from cellulose fibers and protein fibers are potential candidates for the growth and transmission of pathogenic organisms due to their porous structure and ability to retain moisture, they provide suitable conditions for microbes [16].…”

The present work aims to confirm the sustainability of the environment for future generations, decrease pollution caused by textile printing, overcome the problems of using synthetic colorants, thickeners, and fabrics on ecological balance and human health, This research aims to study the effect of using chitosan and chitosan nanoparticles in printing natural fabrics with natural dyes to contribute achieving health and functional aspects, and improving functional properties for natural fabrics and to emphasis on keeping up with global trends using Nanotechnology, Also, to produce antimicrobial fabrics to enhance the quality of the fabrics, by using three different methods pre-treatment, simultaneous, and post-treatment. Color strength (K/S), tensile strength, and all fastness properties were measured for each method. The results of the tests obtained that the K/S value of the treated fabrics with chitosan nanoparticles higher than the treated fabrics with chitosan and all treated fabrics have high fastness values for washing, perspiration, and rubbing. All treated fabric printed with Curcuma shows low light fastness properties. An ultraviolet protection factor (UPF) values of all the treated fabrics, printed with Curcuma and madder are higher than those of the blank ones referring to more ultraviolet protection. The turmeric, berberine, and madder were suitable as an antibacterial agent for Staphylococcus aureus, and Escherichia coli microorganisms. Chitosan nanopaticles more antimicrobial activity than chitosan. This led to an improvement of the function and health properties and quality of end fabrics while maintaining the ecological balance, and Increase the durability of treated natural fabrics and the default service life.
