A Study of Microcapsules Containing Psidium Guajava Leaf Extract for Antibacterial Agent on Cotton Fabric

Jiraphorn Katewaraphorn and Arunee Kongdee Aldred
AbstractPsidium 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.
