Technical Abstract: Microencapsulation is a procedure in which active substances coated by nano-micro size small capsules. This technology has been used in the cosmetics field as well as in the pharmaceutical, agrochemical and food industries for flavors, acids, oils, vitamins, microorganisms, among others. The achievement of this technology is due to the correct choice of the wall material, the core release form and the encapsulation method. Furthermore, research and development are still needed to identify and develop new wall materials and to improve the existing methods of encapsulation for the better use of microencapsulation and its potential applications. The use of flame-retardants for textiles has undergone a significant evolution due to environmental issues related to the use of certain types of high performing flame retardant. In the last three decades, many of the high performing formaldehyde- or halogen-based flame-retardants for fabrics have been excluded from commercial use, thus favoring the use of organophosphate compound. In this study, a melamine tritolyl phosphate (TTPA) microcapsules were developed. Cotton fleece were treated with TTPA microcapsules with binder to provide different add-on values. Treated fabrics were tested for flammability by such methods as vertical flame (ASTM D6413-99), 45 degree angle flame (ASTM D1230-01) and limiting oxygen index (LOI, ASTM D2863-09) tests. Additional thermal properties of desired products were discussed using thermogravimetric analysis (TGA) and microscale combustion calorimeter (MCC).
