Biotextiles are structures composed of textile fibers designed for use in specific biological environments where their performance depends on biocompatibility and with cells and biological fluids. Biotextiles include implantable devices such as surgical sutures, hernia repair fabrics, arterial grafts, artificial skin and parts of artificial hearts. They were first created 30 years ago by Dr. Martin W. King, a professor in North Carolina State University’s College of Textiles.
