of existing properties and the creation of new material properties are the most important reasons for the functionalization of textiles. Keeping this emerging trend in view,
the present research work has been undertaken to explore various traditional materials, methods and the latest application techniques being used for multifunctional
finishing.
A thin film fabrication technique, known for its simplicity in methodology as
the LBL technique, is used for surface modification. Strong electrostatic attraction
between the charged substrate and an oppositely charged molecule in the other solution leads to deposition of polyanions and polycations on the fabric surface. This
phenomenon has long been known to be a factor in the adsorption of small organics
and polyelectrolyte. But it is rarely observed in molecular layer formation. The accumulation of multilayers on solid substrate by layer by layer technique is a unique
novel approach for the fabrication of ultrathin films on solid substrate [2]. This technique has been used earlier for the application of chrysanthemum oil nanoemulsion
on nylon net fabric for mosquito repellent activity [3]. The application of titanium
dioxide nanoparticles by layer by layer technique has also been reported on nylon
fabric for its antibacterial property [4]. One of the recent trends in textile industry
is “nanotechnology” which can provide high durability for fabrics as they have a
large surface area to volume ratio and high surface energy, thus presenting better
affinity for fabrics, leading to an increase in durability of the finish [5]. Keeping this
emerging trend in view, nanotechnology and layer by layer application technique
can be used to develop multifunctional products.
2 Materials
2.1 Textile Substrate
120 GSM plain woven scoured and bleached cotton fabric with EPI: 120, PPI: 80
and 40s count in the direct system, supplied from Piyush Trading, Mumbai, India
has been used for the experimentation.
3 Chemicals
Peppermint oil has been procured from Shreeji Aroma Enterprise, Mumbai, India.
Sorbitan monooleate (Span 80, chemically pure grade) as a lipophilic surfactant and
polyethylene 20 sorbitan monooleate (Tween 80, of chemically pure grade) as a
hydrophilic surfactant used as surfactant in oil in water nanoemulsion preparation
were supplied by Croda Chemicals Pvt. Ltd. India. Cationic and anionic polyelectrolytes, polyethyleneimine and polyacrylic acid of Sigma Aldrich were procured
from Rarco Research Lab, Mumbai, India.
