Elaboration and Characterization of Polyurethane-based Microcapsules: Application in Textile

Nedra Azizi, Neji Ladhari and Mustapha Majdoub
The aim of this study was to elaborate a textile odorous or a fireproof one using microcapsule. Polyurethane (PU)-based microcapsules containing the diammonium hydrogen phosphate (DAHP) as a flame retardant or the neroline as an odorant entity were prepared and characterized. The microcapsules were synthesized by interfacial polycondensation of toluene disocyanate and triethylene glycol. Microcapsules were characterized by optical microscopy and FT-IR spectroscopy. The thermal properties of membrane were analyzed by differential scanning calorimetry and results showed that PU microcapsules were thermally stable till 280°C. The study of inflammability of the cotton fabrics coated with DAHP-loaded microcapsules showed a decrease of flame propagation speed, compared to the untreated fabric. In order to evaluate the adhesion of microcapsules to textile, washing and rubbing tests, had been investigated. Neroline/DAHP-loaded microcapsules showed a good fastness and remained after a six cycle washing. In the case of DAHP-loaded microcapsules the flame retardant action is significant.
