Assessment of colorimetric, antibacterial and antifungal properties of woollen yarn dyed with the extract of the leaves of henna (Lawsonia inermis)

This paper investigates the dyeing and antimicrobial properties of jute fiber with natural dye henna after treatment with biopolymer chitosan. The treatment was carried out by applying chitosan solution on the fiber followed by dyeing with henna dye. Then, the performance was assessed in terms of the depth of shade by measuring K/S value and colorfastness properties of chitosan-treated dyed fabric samples. It has been observed that chitosantreated fabrics showed a higher depth of shade compared to untreated dyed samples. As far as colorfastness is concerned, the dyed samples with and without chitosan pretreatment exhibited almost similar dry rubbing fastness. However, chitosan-treated fabrics showed inferior fastness ratings for wet rubbing and washing, particularly for the fabrics with higher chitosan concentrations. Again, the experimental results demonstrated that the combination of chitosan and henna dye can significantly enhance the antibacterial activity of jute fiber against the organism Staphylococcus aureus and Klebsiella pneumoniae. These findings suggest that the application of chitosan and natural dye from henna onto jute fiber is an approach to get the desired dyeing and antibacterial property.

“…using FeSO 4 has 80% reduction of Staphylococcus aureus. Moreover, the dyed nylon with pomegranate extract/FeSO 4 attains a reduction percentage of 87% of Staphylococcus aureus and 65% of Klebsiella pneumonia [52]. In some cases, presence of FeSO 4 decreases the antimicrobial activity compared to its absence due to the involvement of some hydroxyl groups in coordinate bond with metal mordant which becomes inactive against bacteria and fungi.…”

In this study, eco-friendly natural coloring matter such as pomegranate, curcumin, cutch, red onion peel and a mixture of red onion peel/curcumin (40 g/L, 50%) are used. They are extracted in water at 80°C (red onion at boiling). Cotton, wool, silk and nylon fabrics are dyed using conventional method at pH 4 (except cotton at pH 8), liquor ratio 1:40 and 25 g/L dye concentration for a specific time in presence or absence of FeSO4 using simultaneous mordanting method. Colour strength (K/S) and colorimetric data (L*, a* and b*) are measured at specific λ max . Also, fastness properties (light, washing, rubbing) are determined. Also, ultraviolet protection and antibacterial activity of fabrics against micro-organisms strains of Staphylococcus aureus, Klebsiella Pneumoniae and Candida albicans are measured. Results of the dyed fabrics are highly UV protective and have effective antibacterial activity. All the above dyed fabrics are suggested to use in the medical cloths.

“…Recently, dyes derived from naturally occurring sources such as plants, insects, animals, and minerals have been extensively studied for their dyeing properties [12,97]. These dyes are obtained without any chemical processing and generally exhibit better biodegradability and compatibility with the environment [98,99]. Owing to their recently discovered functional and medicinal properties, such as UV protection, antimicrobial and antioxidant activities, and deodorizing ability, they are emerging globally for use in functional textiles [100][101][102].…”

Textiles production processes such as sizing, scouring, bleaching, mercerizing, dyeing, printing, and finishing are characterized by a huge consumption of water, energy, and chemicals. The toxic effluent discharge generated in these processes mainly contains by-products, residual dyes, salts, acids and alkalis, auxiliary chemicals, and other solvents. Their discharge into neighboring water bodies is posing a serious threat to the flora and fauna. At present, however, development in the textile and clothing industry has focused on the use of some green technologies as alternatives to conventional wet processes to promote sustainable production and consumption of textiles and clothing. In recent years, emphasis has been put on developing cleaner, cost-effective, and value-added textile products for a variety of applications without compromising the issues related to health and the environment. This chapter is intended to provide a summary of recent developments in the coloration and finishing of textile fibers and to provide details of the ecofriendly strategies developed to reduce the waste generation in the textiles and clothing sector. Finally, their implications in the sustainability of clothing products are also outlined.
