Abstract: Fragrance and flavor have been widely applied in food, textile, leather, paper, cosmetic and detergents. The long released aromatic products have attracted more attention in the world. The key scientific problem of the function mechanism bet ween nano fragrance and fiber materials has been focused. Through this project, the large-scale preparation of fragrance nanocapsules can be extended. And the aroma synergism and long release property of the aromatic productions can be primarily resolved. Therefore, the three guides of technology-production-standards of fragrance nanocapsules and aromatic fiber productions should be realized.
