Natural dyes and its Antimicrobial effect

Antimicrobial activity of cotton and silk fabrics dyed with Datura stramonium (Jimson weed) plant leaf extracts

“…The mordanted fabric samples all showed good to excellent (4 -5) fastness properties to light, washing, and rubbing. This may have been attributed to the presence of tannins in the dye extract (Bhuyan et al, 2016) as well as mordants used which helped the dye to bond well with the fibre matrix. In general, cotton and silk fabrics dyed with the D. stramonium extracts using mordants (Alum and Iron Sulphate) gave very good acceptable fastness properties having in mind that natural dyes normally exhibit low substantivity to fibres and fabrics.…”

“…Recently, various research have shown that indeed textile fibres provide an excellent substrate and conditions for the growth of micro-organisms (Morais and Guedes, 2016;Bhuyan et al, 2016). These microorganisms can transfer infectious diseases as well as cause discolouration, bad odor, and garment degradation.…”

“…This has been well examined by the use of Citrus grandis osbeck for its antimicrobial effect on fabrics (Yi and Yoo, 2010) and use of Aloe vera extract and its natural antibacterial finishing for textile applications (Nadiger and Shukla, 2017). Several reports have confirmed that natural dyes can be used not only to provide colour but also reduce microbial growth (Narayanaswamy et al, 2013;Ali, 2015;Rajendran, 2011;Bhuyan et al, 2016). Like these, many natural resources that impart antimicrobial properties to textiles were found and investigated deeply.…”

“…The leaf extracts of D. stramonium were studied and approved to have excellent antimicrobial activity against micro-organisms based on the availability of large amounts of bio-active compounds such as tannins, flavonoids and alkaloids, which are effective against bacterial and fungal infections (Bhuyan et al, 2016). Also, it has been proved that these antimicrobial agents which have varying composition and concentration in different plant parts are usually accumulated as secondary metabolites in plant cells (Tawiah et al, 2016) and that leaves possess the highest antimicrobial activity levels thus opted for in therapeutic applications (Gutarowska et al, 2013).…”

Antimicrobial finishes for Textiles

“…Although, synthetic dyes contain a range of vibrant color and are extensively used but now a day, natural dyes gaining interest because of strict environmental standard forced by a number of European states due to carcinogenicity and photosynthetic issues of synthetic dyes. Natural dyes are considered as eco-friendly, nontoxic, medicinal features [67]. The essential oil extracted from Rosemary (Rosmarinusofficinalis) and orange (Citrus sinensis) were obtained by steam distillation from rosemary vegetal mater and orange peel used to evaluate the antimicrobial activity for textile substrate (56% cotton/44% polyester) with concentration of 1%, 3% and 5%of each oil and antimicrobial activity was assessed against each strain.…”
