Microencapsulation technology in textiles: A review study

Sonu Rani and Alka Goel
“Small is better” motto is true to microencapsulation process. Small microcapsule do fascinating job. Microencapsulation technology allows liquids, solids, or gases to be encapsulated inside a tiny sphere known as microcapsule. Microcapsule is a tiny sphere with uniform wall around it. The particle component is called as the “core material”, and polymers are known as wall material, shell, coating, carrier, or encapsulant. Microencapsulation is done to protect the core material from light, moisture, temperature, and oxygen, to extend shelf-life and to enhance release properties of compounds. Microcapsules can be categories into microcapsules or nanaocapsules, monocored microcapsules, polycored microcapsules and matrix type microcapsules. Microcapsules can be prepared by using spray drying, pan coating, centrifugal extrusion, solvent evaporation, simple coacervation, complex coacervaton, In situ polymaerzation of, in interfacial polymerization. Microcapsules can be used in phrase change materials, fragrance finishes, fire retardant materials and antimicrobial finishes. Need arises for optimization of the methods for formation of microcapsules and extend the shelf life of treated materials to achieve large scale industrial production.
