“…The preparation of silica microcapsules often uses the sol-gel method. [95][96][97] This method requires relatively low conditions for preparing nanosilica. However, some of the raw materials used are organic substances (such as ammonia), which are harmful to the human body and the environment.…”

Silk, a natural protein fiber, is top-rated with people as skin-friendly clothing for centuries. However, silk fiber (SF) still has disadvantages such as photoinduced aging and yellowing and wrinkling. Higher value, as well as novel and unique functions, are added according to the application of microencapsulation in the functional finishing of SF. By using microencapsulation technology, finishing agents, special functional materials, and so forth, can be encapsulated in polymer film-forming materials to form microcapsule finishing agents. Since the properties of the coated materials will not change after the formation of microcapsules, the functional materials can be protected.Only during processing or use, under the external environment such as pressure, friction, and temperature, can the microcapsules be ruptured or released through the diffusion effect of the microcapsule wall to achieve good and desired effects. In this review, recent developments in microencapsulation technology in the application of SFs are highlighted. First, the basic principle and technology of microencapsulation are introduced. Subsequently, adhesion between microcapsules and SFs are described. Finally, the application and effect of microencapsulation technology in SFs are summarized. In addition, the potential challenges and future prospects of microencapsulation technology in natural SFs are discussed.

The interactions between nanoparticles and materials must be considered when preparing functional materials. Although researchers have studied the interactions between nanoparticles and inorganic materials, little attention has been paid to those between nanoparticles and bio-based protein materials, like leather. In this study, organically modified silica nanospheres (SiO2 nanospheres) loaded with rose fragrance were prepared using (3-aminopropyl) triethoxysilane (APTES), (3-mercaptopropyl) triethoxysilane (MPTES), or 3-(2, 3-epoxypropyloxy) propyl triethoxysilane (GPTES) using the sol-gel method. To study the interactions between the modified SiO2 nanospheres and leather, a non-cross-linking adsorption experiment was conducted. According to the Dubinin–Radushkevich isotherm calculation, we found that the adsorption process of leather fiber and organically modified silica nanospheres is physical. The average adhesion energies of APTES-, MPTES-, and GPTES-modified SiO2 nanospheres on the leather are 1.34016, 0.97289, and 2.09326 kJ/mol, respectively. The weight gain, adsorption capacity, and average adhesion energy show that the modified SiO2 nanospheres can be adsorbed on leather in large quantities. The sensory evaluation confirmed that GPTES-modified SiO2 nanospheres endowed the leather with an obvious rose aroma.

“…For example, microcapsules are a commonly used physical method of sustained release of a fragrance, using the shell to separate the active and volatile aromatic compounds from the outside environment, [4][5][6] and some further applications of encapsulated aromatic compounds on various fabric surfaces have also been reported by our group. [7][8][9][10] Another method is to generate fragrance precursors (so-called "profragrances"). 11,12 The profragrance system consists of fragrances and substrates bonded together, and the perfume molecules are gradually released once triggered by moisture, heat, light, enzymes and so on with the tunable release rate controlled by the intensity of the stimulus.…”
