Generally, aroma essential oil has been studied in the microencapsulation used polymer for aroma-finishing of fabrics. But protuberant microcapsules, which are larger than binder layer, can be easily broken by frictional forces. So conventional microcpasules has disadvantages of low durability and short period of time for using. In this work, we controlled polymer particles containing aroma essential oil to nano-sized capsules, that is under the application of emulsification-diffusion method. These aromatic nano-capsules are buried inside of fabrics that can rarely be attacked by frictional forces. They may be not only delivered by controlled release mechanism but also will have superior durability. Therefore, we preparaed poly(vinyl acetate) aromatic nano-particles and conducted an release experiment for confirming sustained release behavior. |
