Development of Highly Hygienic Textile by Coating with Encapsulated Ginseng Oil

There is a growing demand for the development of functional textile sanitary products to protect the human body from viruses, bacteria, and other harmful external substances. However, common processing methods for textile functionalization result in poor durability or have a highly limited material scope. A solution for this is the encapsulation of the functional material to provide stable protection and controlled release to reveal functionality in the fabric. However, many chemicals used for such purposes can cause problems for both human beings and the environment; therefore, attention is being shifted to natural products such as essential oils and seed oils. In this study, we used in situ polymerization to encapsulate ginseng oil, which has antibacterial, deodorizing, moisturizing, and antioxidant functions, as the core material of the microcapsules. The manufactured microcapsules were spherical with smooth surfaces, had an average size of 3.98 um, and exhibited excellent thermal stability. Processing the synthesized microcapsules into nylon/polyurethane fabric resulted in excellent functionalities, with the treated fabric exhibiting a 99.9% antibacterial activity against Staphylococcus aureus and Klebsiella pneumoniae and a 99% deodorizing effect. Therefore, the developed method is expected to show great potential for the production of highly hygienic textiles for use in various industries.
