RESUMEN
Medical textile is one of the technical textiles sectors, growing faster due to developments in polymer science and technology and innovation in forming new textile structures. In this review, current market trends for the growth of medical textiles for both pre and post covid pandemic periods were discussed. Focus is given to the classification of medical textiles and devices, specific requirements of fibers and widely used types of fibers, and advanced developments in this field, including nanofibers, bicomponent fibers, superabsorbent polymers, and conductive materials used in a wide range of advanced medical devices. Various fabric structures (woven/knitted/nonwoven/braided) have been in use in biomedical devices;however, recent 3D shaped structures such as spacer fabrics, and 3D-printed materials have profoundly marked their significance with its ability to adapt to specific needs of the medical community. Smart wearable sensor technologies for monitoring, diagnosis, and treatment are discussed and critically reviewed, enabling the readers to understand the complexity of the nature of interdisciplinary approaches required for developing such complex structures and systems. Antimicrobial agents (synthetic and natural/organic) used in the development of medical textiles mainly wound dressings, advances in antiadhesive textile coatings, and antimicrobial assessments of medical fabrics are critically reviewed. Finally, a case study on 3D printing of complex structures is presented to update modern developments using fine detail resolution (FDR), a selective laser sintering that uses carbon dioxide laser to produce delicate and complex 3D structures suitable for medical applications. It is anticipated that readers will benefit from this critical overview of trends in this sector and the multidisciplinary approaches needed to meet the demands of the ever-growing consumer base. © 2023 Elsevier Ltd.

RESUMEN
Humans are surrounded by numerous pathogens, which can cause severe infections and even become a source of death. The world has seen the impact of COVID-19 on the health and economic sector and continues to see the other impact if corrective measures are not taken. Similarly, the impact of bacteria on the human body has increased noticeably over the past few years, and is one of the significant challenges the healthcare sector faces. Therefore it is imperative to focus on the systems through which the impact of pathogens could be reduced. Scientists are rigorously working on the development of biological protective textiles using the encapsulation of organic compounds to protect the user from harmful pathogens. This chapter will review recent advancements in the development of biological protective textiles using encapsulated organic compounds. The fundamentals of micro/nanoencapsulation and the most important encapsulation techniques used for the development of microcapsules loaded with organic compounds (essential oils) will be described. The application of various organic compounds onto textiles through suitable encapsulation techniques will also be discussed. The control-release kinetics with mathematical modeling will be thoroughly discussed to understand the release behaviors of microcapsules. Novel biological protective textiles such as antiviral, antibacterial, antifungal, antioxidant, mosquito repellent, insect repellent, etc., will be reviewed. Finally, the mode of action of essential oils against viruses, pathogens, insects, mosquitoes, and oxidants will be explained. © 2023 Elsevier Ltd. All rights reserved.
