The first recorded use of Fibres – ‘Surgical Papyrus’ 4000 years ago

Materials used - Horse Hair, Leather Strip , Cotton , Animal Sinew and Fibrous tree bark - Source ‘Susanta Sambita’


Brief History of Medical Textile

Medical Textile developed with development of

our knowledge of wound closure Sutures(5000 – 3000 BC)

Flax , Silk , Linen strips & Cotton were extensively used Lubricated with oils / Wine – Susruta ( 800 BC)

Use of Sutures & Clips - Celsus (30 AD)

Silk & Catgut – Galen ( 150 AD)



Fast Facts

Medical textiles are textile products and constructions for medical applications

They are used for first aid, clinical or hygienic purposes Implants and rehabilitation

Biomedical textiles are fibrous structures designed for use in specific biological environments, where their performance depends on biocompatibility with cells and biological tissue or fluids
