Abstract:
Host-guest complex of β-cyclodextrin-cochitosan and lavender was employed for the combined
aroma cum anti-bacterial finishing of cotton textiles.
The modified host viz. β-cyclodextrin-co-chitosan was
synthesized with the use of β-cyclodextrin citrate as the
intermediate for the achievement of the satisfactory
yield of the host. FTIR analysis was carried out for the
characterization of β-cyclodextrin-co-chitosan and also
the surface modification of the functionalized cotton
with the modified host. 1HNMR spectra of the inclusion
complex of β-cyclodextrin-co-chitosan and Lavender
had confirmed the formation of a strong complexation
between the two compounds. The functional as well as
physical properties as aroma retention, anti-bacterial
assessment, tensile strength, crease recovery, bending
length and air permeability were investigated both for
the host-guest complexed cotton and lavender alone
treated cotton. The aroma retention and a strong
inhibition zone was found more pronounced in the
functionalized cotton instead of the oil alone treated
cotton, which can be a promising and potential cadre of
application of multi faceted textiles.
