Applications and characterization methods of nonwovens in biomedical field

Abstract

Technological advancements and increasing demands have led to significant innovations in the field of materials science. Nonwoven materials, a crucial subfield of the textile industry, have garnered substantial interest and have a broad range of applications in the biomedical field in recent years. Nonwoven fabrics are produced through methods that bind or interlace fibers directly, rather than using traditional weaving or knitting techniques. These materials are characterized by their flexibility, light weight, and cost-effectiveness. Due to their production process involving irregular fiber arrangement and various bonding techniques, nonwoven materials offer advantages such as low cost, lightweight, flexibility, and rapid production. Their properties, including high durability, low weight, and high air permeability, make nonwoven materials effective solutions for applications such as wound dressings, drug delivery, hygiene products, and biological signal monitoring. The broad application scope of nonwoven materials necessitates precise characterization of their physical, mechanical, and chemical properties. This characterization is crucial for determining the performance, quality, and application potential of the materials. Characterization methods for nonwoven materials involve evaluating the structure, strength, permeability, absorption capacity, and other essential attributes of the material. This paper provides a comprehensive review of the characterization methods for nonwoven materials, focusing on their applications in the biomedical field. Various characterization techniques employed to determine the properties of nonwoven materials are discussed in detail, based on current research literature. © (2024), (Chamber of Textile Engineers).
