Dyeing behaviour of gamma irradiated cotton fabric using Lawson dye extracted from henna leaves (Lawsonia inermis)
TL;DR: In this paper, the color strength of gamma irradiated cotton fabric using henna leaves has been evaluated using CIE Lab system using Spectraflash-SF650 and it has been found that gamma ray treatment of cotton dyed with extracts of henna leaf has significantly improved the colour strength as well as enhanced the rating of fastness properties.

Antimicrobial effect of natural dyes on some pathogenic bacteria
TL;DR: The textile material impregnated with four natural dyes and maximum inhibition rates (respectivelly, 80, 86, 52%) were obtained against B. subtilis of wool samples dyed with P. tinctorum while maximum inhibition rate (91%) was found against P. aeruginosa of wool sample dyed with R. cepa.
