Conclusion
New red pigment was extracted from prickly pear juice and
used with different mordants as natural dye for dyeing wool
with good fastness properties and high dye uptake.
Antimicrobial activity of wool fabric dyed with this dye was
tested according to diffusion agented. Test organisms asE. coli,
B. subtilus Pseudomons aeruginosa and Staphylococcus aureus
were used and the results indicated that the samples exhibited
a high inhibition zone. Our study shows that natural red
prickly pear dye under investigation can provide bright hues
and color fastness properties. They can serve as a noteworthy
source of raw material in the future. Chemical modification of
natural compounds such as the dye in question could be an
interesting field of study as it could appreciably facilitate the
synthesis of dye molecule.
