Antibacterial, Uv Protective and Antioxidant Linen Obtained by Natural Dyeing With Henna

Abstract

Textile materials have become one of the functional needs of human beings and their multifunctional properties are highly demanded. Linen has been gaining rising interest and the multifunctional modification of this fiber can produce value-added textile products. In the present study, linen fabric was modified using natural dyeing with a combination of henna and copper sulphate. The resulting colored substrate was characterized using FTIR, TGA and SEM techniques. The color values of the dyed samples, for the various combinations of mordant and dye concentrations, were evaluated, along with the functional properties, such as antioxidant activity, antibacterial action and UV protection. The modified linen showed wash-fast coloration and displayed efficient protection against bacteria, UV light and free radicals. The multifunctional properties were retained after 20 washes. The henna-dyed linen can be claimed as a green multifunctional textile material that can be used for enhanced protection.

Nanomaterials for UV protective textiles

“…UV protection of fabrics increases with increasing color value due to the combined effect of mordant and dye molecules. Optimum sample showed an UPF of around 45 which considered as excellent [74]. UV blocking property of woolen fabric which has been dyed with natural dye extracted from grape pomace showed a significant improvement of UPF from 5 for undyed fabric to 30 for dyed fabric without using any mordant.…”

Creation of a Functional Cotton Headcover (turban/bonnet) via Lac and Turmeric Natural dyes

“…The need for protection against dangerous agents like germs, UV light, free radicals, and others has arisen as a result of growing public knowledge of their negative effects. (Yadav et al, 2019). Functional antibacterial and antioxidant clothes can confer health benefits.…”

“…In addition to that, natural dyes have good UV protection, antibacterial activity, and antioxidant activity when applied to textile materials (Mulec & Gorjanc, 2015;Rather et al, 2017). Turmeric and lac natural dyes can be employed for cotton fabric to create colored multifunctional textiles (Yadav et al, 2019). The most often used natural dye for textile dyeing is turmeric.…”

“…As a result, its use in various products is increasingly popular, including clothing, bed linens, and head scarves. (Yadav et al, 2019). Due to its numerous properties, cotton is the most popular textile material used to knit fabric, especially for summer clothing and sportswear.…”

“…Innovative techniques have been used, such as coating the fabric with chitosan to improve the dyeability of cellulosic fibers, which are more challenging to dye with natural dyes than proteinbased fibers. (Yadav et al, 2019). Chitosan is a polycationic amino polysaccharide that has acquired great importance as a new functional material for textile materials mainly because of its biocompatibility, non-toxicity, and fabulous biological properties.…”
