“…The powdered heartwood of A. catechu contains tannin phyto-constituents and is used for textile coloration from ancient times to impart brown tint shades on textile materials (Bhattacharya and Shah 2000;Bhattacharyya and Lohia 2002;Vankar et al 2008;Perkin & Everest 1918). Pharmacological studies have demonstrated that A. catechu used in traditional medicines shows anti-inflammatory and anticancer activities (Anonymous 2006;Khan et al 2011).…”

In the present study, anthraquinone colorants were extracted from powdered Rubia cordifolia roots and applied on wool fiber. Acacia catechu is used as a biomordant, a replacement to metallic mordants, for wool dyeing, and the effect on color characteristics and fastness properties was assessed. Shades on wool of red tones with good to excellent color fastness properties were obtained. Pre-mordanting with A. catechu improved the overall color and fastness parameters, due to the maximum dye uptake. Auxochromic groups responsible for interaction of dye and wool were studied by Fourier transform infrared (FTIR) analysis of R. cordifolia extract. The surface morphology of dyed wool fiber was investigated by scanning electron microscopy (SEM) for any changes on fiber after dyeing.

“…It is also reported that natural dyes can not only be used to get natural shades but they can also provide functionalities to fabrics such as antibacterial activity (M. I. Khan et al 2011;Shahid et al 2012), antifungal activity , and ultraviolet protection (Zhou et al 2015).…”

In the present study, Terminalia chebula (Myrobalan/Harda) natural dye extract was used for the development of eco-friendly shades on woolen yarn with different hues and tones. The effect of dye concentration on color strength (K/S) of woolen yarn dyed with T. chebula was assessed. Increasing the concentration of dye decreased lightness (L*) values of woolen yarn samples, indicating darker shades. Different metal salts such as alum, ferrous sulfate, and stannous chloride were used to enhance the fastness properties (light, wash, dry and wet rubs) of dyed woolen yarn. Pre-treatment of woolen yarn samples with metal salts has shown encouraging results with better fastness properties and enhanced color strength values. Five percent ferrous sulfate mordanted samples show greater saturation with increasing dye concentration from 0.5 to 15 % (o.w.f.). Fourier-transform infrared (FT-IR) analysis of T. chebula dye extract shows presence of carbonyl and hydroxyl functionalities.

Abstract-Psidium Guajava Linn. leaf extract containing phenolic compounds are known for antimicrobial activity. This study's objective was to prepare antibacterial cotton fabric by using microcapsules containing Psidium guajava Linn. leaf extract. Microcapsules containing Psidium guajava Linn. leaf extract were prepared by in situ polymerization using urea and formaldehyde for encapsulation. Both Psidium guajava Linn. leaf extract and microcapsules containing Psidium guajava Linn. leaf extract have been applied to cotton fabric by direct printing with a binder. The qualitative antibacterial assessment of the fabric was performed according to AATCC 147-2004 against Escherichia coli and Staphlococcus aureus as test organisms. The antibacterial tests proved that the cotton fabric finished with microcapsules containing Psidium guajava Linn. leaf extract showed antibacterial activity against Staphlococcus aureus, but was not effective against Escherichia coli IndexTerms-Poly(urea-formaldehyde), microcapsule, Psidium guajava Linn., antibacterial textile.
