Propolis is a gum gathered by honey bees from various
plants; the honey bees use propolis to seal holes in their honey combs, smooth
out the internal wall and protect the entrance against intruders. It is
composed of 50% resin (flavonoids and related phenolic acid), 30% wax, 10%
essential oils., 5% pollen and 5% various organic components. As a natural
mixture, propolis is widely used in medicine and cosmetics and food. So far no
attempts have been yet made to make use of propolis in the realm of textile
finishing .
Current work presents the first systemic study targeted to
build up a scientific basis for production of cotton textiles having
antibacterial activity and other useful properties by making use of propolis as
eco-friendly finish within the scope of green strategy.
Propolis extract solution (70/30 ethanol/water) of 10%
concentration was prepared as the stock. Different amounts of the latter were
used along with a crosslinking agent and catalyst for treatment of cotton
fabrics as per pad-dry-cure technique. Antibacterial activity of the so treated
fabrics was obtained through monitoring the efficiency of the interaction of
propolis with cotton cellulose. This interaction was expressed as inhibition
zone diameter after the treated fabrics were exposed to (G +ve) and (G-ve)
bacteria .
Other properties include crease recovery, tensile strength and elongation at break. Factors affecting these properties such as type, nature and concentration of the crosslinking agent, concentration, of propolis, and conditions of curing were investigated. In addition characterization of the propolis containing modified cotton fabrics including demonstration of the antibacterial activity, SEM, FTIR, durability to washing, UV protection and water repellency were performed.
Based on results obtained It is concluded that
application of propolis along with glyoxal and Al2(SO4)3 catalyst using pad-dry
(3min./80°C), cure(5/140°C) bring about cotton textile with superior
antibacterial activity, water repellent and ease of care characteristics as
well as UV. Protection .Tentative mechanism of the reaction of propolis with
cotton in presence of glyoxal was also reported.
