Microencapsulation is a natural phenomenon and the examples of ideal microcapsules are found in the nature i.e., spores, seeds, eggs and pollen etc only a few to mention. Due to numerous applications of microencapsulation and as a result there are a number of processes developed to encapsulate a galaxy of materials to suit the individual applicability. In the broadest sense, microencapsulation provides a means of packaging, separating and storing solid and liquid materials in a microscopic scale for a later release on your own desire under controlled conditions.
The fragrance compound and the essential oil are volatile substances. The most difficult task in preparing the fragrance emitting textile is how to prolong its lifetime of Odour. Micro-encapsulation is an effective technique to solve this. Microcapsules are minute containers that are normally spherical if they enclose a liquid or gas, and roughly of the shape of the enclosed particle if they contain a solid. It can be considered as a special form of packaging, in that particulate matter can be individually coated for protection against environment and release the volatile substance from the enclosed capsule as required. This property has enabled microcapsules to serve many useful functions and find applications in different fields of technology. For example, the storage life of a volatile compound can be increased markedly by microencapsuling. The key to aromatic textile is how to make microcapsules of fragrance com-pounds and essential oils without omitting any ingredient in order to ensure its effects. In addition, using a low-temperature polymer binder to attach a perfumed microcapsule to the surface of the textile is also an important part of preparing an aromatic textile. At the same time, durability in laundering and a soft handle should be carefully considered
