Microencapsulation is one of the special finishes applied on a textile. Microencapsulation technologies involve an encapsulated of a compound inside a tiny sphere known as microcapsule, in which various active materials such as drugs, vitamins and flavors are effectively encapsulated with a formation of microcapsules. These microcapsules release their contents at appropriate time by using different release mechanisms. The aim of this thesis was to produce micro-particles of sodium chloride using the physical process of microencapsulation. Spray drying process was used for formation of powder of sodium chloride containing micro-particles; the particles were measured and analyzed. The powdered form was applied on a fiber samples consisting of bicomponent fibers for observation of any changes in the fiber properties. The second objective was to produce microcapsules of phase change material using spray drying process. Paraffin wax was used as a phase change material. Microcapsules were measurements and analyzed according to the distribution of the microcapsules.
