The present study highlights about Eco-Friendly Anti-Microbial Textile Finish using Cinnamon Bark (Dalchini) and Garcinia indica (Kokum). Garcinia indica is a plant from mangosteen family and is commonly known as "Kokum". It can be easily found in almost all kitchens of India. There is a vast use of the fruit of Garcinia indica as remedial medicine in Indian system of medicine for treating various ailments.
The inherent properties of the textile fibres provide room
for the growth of micro-organisms. There are many anti- bacterial fibres and
chemicals available in the market but unfortunately, they are from synthetic
base and are not eco- friendly. Consumers in India are taking the lead in
encouraging firms to use clean technologies to create environmentally
beneficial products. Many natural plant products, such as extracts from roots,
stems, leaves, flowers, fruits, and seeds, exhibit antimicrobial characteristics.
In the present study, anti-microbial finish has been imparted to cotton fabric
using ethanolic and acetonic extracts of Cinnamon Bark and Garcinia indica by
direct application and by microencapsulation. The ethanolic extract was
prepared by using10 gms of herbal material in 100 ml of ethanol and allowed to
stand for 24 hours. The acetone extract of the herbs was prepared by refluxing
40gms of each herb in 400 ml of acetone in a Soxhlet extractor. The extracts
were applied by directly soaking the fabric in ethanol extract overnight and
also by Microencapsulation (for acetone extracts). For microencapsulation, the
herbal extract was used as the core material and Gum acacia as the wall
material. The treated samples were then tested for their anti-microbial
efficiency and also the wash fastness of the finish. It was observed that both
the herbal extracts when applied on cotton fabric gives it an excellent
anti-microbial property against both gram positive and gram- negative bacteria
i.e. Staphylococcus aureus and Klebsiella pneumonaiae. Regarding the wash
fastness of the treated samples, it was observed that the finish does not last
long. The anti-microbial activity diminishes with every wash and at the end of
5th wash cycle no activity was seen against the selected microbes. However, the
limitation of this herbal anti-microbial finish is that it needs to be applied
on fabric that is used for disposable products or the products that requires
very less washing. The direct application method of Cinnamon extract, makes the
treated fabric 91.1% anti-microbial efficient against Staphylococcus aureus and
87.9% against Klebsiella pneumonaiae. Whereas on the other hand, the direct
application method of Garcinia indica on the cotton fabric makes the fabric
93.3% anti- microbial efficient against Staphylococcus aureus and to be noted;
no anti-microbial activity was observed against Klebsiella pneumonaiae through
this method of application.
The results indicate that the treated fabric is 99.99%
anti-microbial and can be used in hygiene products where less washing is
required like pillows, curtains, disposable bandages and quilts.
