“…Since the outer shell of the micro/nanocapsule normally does not react with the silk, most aromatic finishing methods require the use of adhesives, which can ensure that the micro/nanocapsules adhere to the silk to resist washing and friction. [116][117][118] Two types of adhesives, polymer resins with the film-forming ability or multifunctional crosslinking agents, are usually used to fix the microcapsules on the silk substrate. 118 Film-forming adhesives can provide a three-dimensional network to firmly adhere microcapsules to silk, but they may hinder the release of encapsulated functional components and reduce the aromatic strength of aromatic microcapsules.…”

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.

In order to obtain textile materials with potential utility in the development of cosmetic textiles, this study examined the deposition by padding of rose and sage microcapsules on woven textile structures, with different fiber compositions (100% cotton and 50% cotton/50% polyester). Cationization of the textile materials was performed to enhance the degree of uptake the pf the microcapsules on the fabrics’ surface. A commercially acrylate-based binder was used to fix the microcapsules to the textile substrate and to improve the durability against external factors. The finished textile materials were characterized in terms of their physical-mechanical characteristics. The distribution of microcapsules on the fabrics surface before and after five washing cycles and 1000 abrasion cycles was investigated by scanning electron microscopy. The biocompatibility in terms of cell viability, cell membrane integrity and inflammation status of the functionalized fabrics was evaluated on CCD-1070Sk normal human dermal fibroblasts. The cell morphology was evaluated by F-actin staining using fluorescence microscopy and no significant changes were noticed after the incubation in the presence of fabrics compared with control. The in vitro biocompatibility evaluation on human skin cells confirmed the absence of cytotoxicity after the short-term exposure, supporting further in vivo use of these innovative textiles with improved properties.

“…Because there is no or weak affinity between micro‐/nanocapsules and textiles, most of the aromatic finishing approaches described above require a binder, which can ensure the micro‐/nanocapsules adhering in textiles to resist washing and rubbing . At present, while several researchers are focused on the effect of finishing methods and also types of binders on the carrying capability and durability of aromatic textiles finished with micro‐/nanocapsules, particle sizes of micro‐/nanocapsules and types of textile weaving parameters are also the key factors which can affect the carrying capability and durability of aromatic textiles.…”

Aromatic reservation is one of the key evaluation index of textiles which be finished with fragrant micro‐/nanocapsules, and some researches discover that when the fragrant micro‐/nanocapsules penetrating into the spacing of textiles, the resulting aromatic textiles own much better carrying capability of micro‐/nanocapsules. Based on these phenomena, hence in our research, the matching up between pore sizes of cotton textile and sizes of fragrant micro‐/nanocapsules is investigated systematically in order to reveal the size effect on the durability of fragrant micro‐/nanocapsules in cotton textile. Firstly, the pore sizes of cotton textile are analyzed by three different techniques: 3D X‐ray microscopy (Micro‐CT), nitrogen adsorption/desorption method (BET), and mercury intrusion porosimetry (MIP) technique. Based on the pore sizes obtained from MIP technique, citronella oil/chitosan micro‐/nanocapsules with three corresponding sizes are prepared and then applied on cotton textiles through vacuum impregnation process. The pore sizes of cotton textile measured by MIP technique decrease from before finishing to after finishing with nanocapsules, which states that nanocapsules are entrapped inside the pores of cotton textile. Finally, the washing durability of aromatic cotton textile is evaluated by headspace–solid‐phase microextraction (HS‐SPME) technique combining with GC‐MS which can keep the fragrant micro‐/nanocapsules unbroken to simulate the “real” sniffing environment. The results show that aromatic cotton textile treated with nanocapsules possesses much better washing durability, which is met up with the results of pore size measurements: More nanocapsules are penetrating into the spacing of cotton textile fibers even the pores in fibers.
