Sažetak
Functional fabrics meet consumer comfort and safety needs and the use of essential oils can confer functional and sensory characteristics. To aid in the impregnation and long duration of the fragrances when applied to the fabric fiber, microencapsulation technology is used to protect active substances, which in the case of essential oils are volatile. Thus, the protection of essential oils as a susceptible material to the external environment made by microencapsulation can increase the stability of the oil due to its ability to release the active substance by a suitable mechanism and confer stability and mechanical resistance. In addition, applying microcapsules of tea tree oil in cotton fabrics that have retaining structures of hydrophilic water, oxygen and nutrients represents a natural alternative to overcome microbial contamination, since, being natural fiber compounds are sensitive to the growth of microorganisms, such as bacteria and fungi. Therefore, this work presents a study of the production, characterization and application of microcapsules of tea tree essential oil (Melaleuca alternifolia) in cotton fabric, seeking to increase the durability and protect essential oil, these natural biocides from reactions with moisture, light, and oxygen. The experimental procedure was to produce microcapsules of shell melamine- formaldehyde polymer by interfacial polymerization method with variations of the amount of CTAB, of surfactant and of melamine- formaldehyde, as well as of the ultrasound times and amplitudes, in order to select the best formulation with respect to the formation of microcapsules and after to apply in the cotton fabric by means of exhaustion process during different times (one hour, two hours and three hours), seeking the most adequate time for the microcapsules to attach to the cotton fabric. As results of the microcapsule applications, it was possible to verify by means of Scanning Electron Microscopy that the selected microcapsule production method combined with the time of application in cotton fabrics by exhaustion process for one hour was more efficient in terms of the presence of microcapsules in the cotton fabric. At the end, the cotton fabric treated with the microencapsulated essential tea tree oil biocide agents higher durability of functionality is expected.
