ting, the antibacterial activity of cotton, wool and silk fabrics
with two natural dyes was found to have been enhanced significantly
against S. aureus and E. coli. These fabrics are found to
have a wash durability of up to 20 washes. Even using 0.5%
(owf) copper sulphate mordant treatment after 15% (owf)
tamarind seed coat mordant and dyed with natural dyes for
all three substrates is adequately enough to obtain a good antibacterial
activity against S. aureus and E. coli bacteria. The
wash and light fastness properties of the dyeing on fabrics were
found to be enhanced when mordanting was done. This process
is promising and should be easily industrialized, popularized
among the local natural dyers in order to obtain an ecofriendly
product with value added properties
