M ANY methods for eco-friendly textile processing have been developed by science, including enzymatic textile finishing, plasma technology, natural product finishing, and microencapsulation. Microencapsulation is an innovative technology that has been utilized to give textiles functional features including antibacterial activity, scent, mosquito repellency, UV protection, and thermoregulation. The volatile and non-volatile components can be contained inside a thin polymeric film in microencapsulation, resulting in a delayed release of the chemical and a long-lasting functional impact. This review study focuses on the primary causes for microencapsulation, key microencapsulation techniques, and applications of microencapsulated goods in many fields of science and technology.

“…The temperature of a sample is further decreased inside the vacuum chamber to a minimum possible value and then slowly begins to increase through sublimation that is explicable with the kinetic theory of gases (Loeb, 2004) and the triple‐phase diagram of water. During sublimation, emphasis is given to primary drying as it leads to sublimation of 80–90% of water content from a sample (Meirowitz, 2019). The question is how one can determine the endpoints of primary drying and secondary drying.…”

Experiments were conducted with pure water to study the various temperature and humidity parameters that can be used to develop the process of a vacuum freeze dryer (VFD). Both temperature and humidity sensors were applied to investigate characteristics such as the resistance offered during drying, heat‐transfer coefficients, moisture content, diffusivity, and others that can influence the process of vacuum freeze‐drying during primary drying. These experiments helped to develop an efficient and optimized process. We discuss the importance of various parameters on drying and the ways in which one can accomplish the experiment of drying. Two conditions, humidity and temperature, were combined to obtain a concurrent output for the start and endpoint of steps involved in freeze‐drying. From the process discussed, we state that when % RH lies between 8% and 10%, primary drying begins and when it lies between 1% and 3%, secondary drying begins.Practical ApplicationsThe practice applications for developed techniques in this manuscript would be food industry, storage of smallpox vaccines, manufacturing of enzymes, proteins, or drugs, and other bio‐related applications by a vacuum freeze dryer (VFD).

“…Recently, textile applications involving the use of microencapsulation of active substances have increased. This technology enhances the durability of the encapsulated material providing some expected benefits to the textile material [4]. Therefore, the active compounds’ functionality is transferred to the material by the finishing treatment.…”

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.
