Abstract—
Psidium Guajava Linn. leaf extract containing phenolic compounds are known for antimicrobial activity. This study’s objective was to prepare antibacterial cotton fabric by using microcapsules containing
Psidium guajava Linn. leaf extract. Microcapsules containing Psidium guajava Linn. leaf extract were prepared by
in situ polymerization using urea and formaldehyde for encapsulation. Both
Psidium guajava Linn. leaf extract and microcapsules containing
Psidium guajava Linn. leaf extract have been applied to cotton fabric by direct printing with a binder. The qualitative antibacterial assessment of the fabric was performed according to AATCC 147-2004 against
Escherichia coli and
Staphlococcus aureus as test organisms. The antibacterial tests proved that the cotton fabric finished with microcapsules containing
Psidium guajava Linn. leaf extract showed antibacterial activity against
Staphlococcus aureus, but was not effective against
Escherichia coli
Index Terms—Poly(urea-formaldehyde), microcapsule,
Psidium guajava Linn., antibacterial textile.
