The synthesis of multifunctional microcapsules using natural polymers has contributed to a broad range of practical applications on fabric coatings. This paper presents a facile and environment-friendly approach for waterborne multifunctional fabric coatings by using cellulose/silica hybrid microcapsules. In this method, lavender fragrance oil-loaded cellulose/silica hybrid microcapsules were one-step synthesized via emulsion solvent diffusion. This microcapsule is core-shell structure with UV absorbers and methacrylic acid grafted silica in the shell and then added into the waterborne polysiloxane resins to form multifunctional fabric coatings. The as-obtained fabric coatings not only exhibited controlled lavender fragrance oil-releasing performance, and it can keep above 30 % fragrance after ninety days due to the slow releasing of lavender fragrance oil in the capsules, but also showed excellent UV resistant property with 159 UPF value.
