The use of nanofiber threads as surgical sutures has been proposed as a way to improve the quality of repairs. However, due to the insufficient robustness of current manufacturing methods, it has not been possible to produce and scale continuous nanofiber threads on an industrial scale, and therefore they are not currently available for clinical use. To solve this problem, we have developed an effective method that enables the production of two classes of electrostatically spun yarns (100% nanofiber yarns and composite yarns with a nanofiber shell) with the potential for use as surgical suture materials. The presentation of production technologies through process and material parameters for the production of nanofiber yarns using alternating current electrostatic spinning, including possible modifications and subsequent treatments such as braiding or surface treatment of nanofibers in yarns, demonstrates the versatility of these materials, in particular through detailed images from a scanning electron microscope. In particular, attention is focused on the basic manufacturing processes and evaluation procedures for nanofiber threads with applications as surgical sutures. The aim of this paper is to show the possibilities and examples of creating biodegradable nanofiber threads as surgical sutures, particularly from a technological perspective.
