When the word “textiles” is mentioned, the majority of the people think immediately of clothes, bed sheets, or perhaps upholstery. But what if I told you that textiles are also silently at work at the back stage of hospitals, operation theatres, ambulances, and even inside our own bodies?
Surely, textiles play a very significant role in modern medicine. They are not just used for covering the wounds – they save lives, contribute to healing, and even aid in the diagnostics and operation. Welcome to the universe of medical textiles- where fibres are not only threads; they are lifelines.
In this blog post, let’s look into what textile fibres have to do with the human body, what the underlying science is, how these textile fibres are used in real life, as well as a few surprising facts that you definitely did not know!
What Are Medical Textiles?
The Medical textiles (also referred to Medtech textiles) are specific designed fabrics and fibres utilized in the healthcare uses and clinical applications. These materials are designed based on safety, hygiene, functionality, and at other times, therapeutic gains.
According to usage, there are four major categories of medical textiles, namely:
- Implantable Textiles – Applied on the inner body (surgical sutures, meshes, artificial ligaments and vascular grafts).
- Non-Implantable Textiles – Applied to the body, not implanted (e.g., wound dressing, compression bandages, gauze).
- Extracorporeal Devices – Outside the body for filtering or support of a biological function (an example is like membranes in artificial kidneys and lungs).
- Healthcare & Hygiene Products – Products such as surgical mask, PPE kits, gowns, hospital bedding, sanitary products.
And these categories are mere tip of the ice berg!
Why Fibre Properties Matter a lot in Medicine?
You may ask yourself the question – why are fibres so important? Can’t we make use of any normal fabric?
- Well, not really. There are very stringent requirements, which medical textiles have to meet. Such fibres actually come directly into contact with skin, wounds, internal tissues and at times blood or internal organs. So, they need to have:
- Biocompatibility – They should not elicit allergic or immunological response.
- Sterilizability – Should be able to stand steam, gamma ray, or chemical sterilization.
- High absorbency or repellency – Based on the application (such as wounds against those for surgical gowns).
- Strength & Flexibility – This is particularly important in implants or bandages.
- Breathability & Comfort-For friendly use on patients.
- Non-toxicity & Durability – Necessary for both disposable and re-usable products.
Performance of the finished medical textile depends on the properties of the fibre that is used. For this reason, fibre selection is in the centre of Medtech innovation.
Main Textile Fibres Applied in Medical Textiles
Let’s make a tour among the most common, and not so known, fibres applied in medicine:
1. Cotton
- 100% natural, soft, and breathable.
- Highly absorbent and skin-friendly.
- Used in: gauze, cotton rolls, swabs, as well as wound dressings.
- Limitation: holds moisture, thus, sometimes mixed with synthetics.
2. Polypropylene (PP)
- Lightweight, water-repellent, and low-cost.
- Thermally bondable, which is perfect for disposable products.
- Used in: surgical masks (N95), PPE kits and medical filters.
3. Polyester (PET)
- High strength and thermal stability.
- Can be made hydrophilic or hydrophobic by modification.
- Used in: medical meshes, artificial ligaments, medical bedding.
4. Nylon (Polyamide)
- Strong, flexible, and chemically stable.
- Used in: sutures, artificial tendons, and catheters.
5. Silk
- Surprised? Silk is indeed one of the natural fibers used in non-absorbable sutures.
- It is also studies on biodegradable scaffolds for tissue engineering.
6. Chitosan Fibres
- Obtained from the shells of shrimp and crab.
- Antibacterial, biodegradable, and promotes healing.
- Used in: wound dressings and skin regeneration.
7. PTFE (Polytetrafluoroethylene)
- Non-stick, chemically inert and very hard-wearing.
- Used in: vascular graft, catheters, and implants.
8. Viscose Rayon
- Soft, absorbent, and biodegradable.
- Many times used in sanitary napkins, wipes, and eco-friendly medical products.
9. PLA (Polylactic Acid) Fibres
- Based on the corn starch or the sugarcane (biopolymer).
- Biodegradable and biocompatible.
- Used in: wound cover, sutures and disposable hygiene products.
10. Carbon Fibres
- Applied in orthopaedic braces, splints and even prosthetics.
- Provides light strength and are radiolucency (X-rays detects through them).
Surprising Real-Word Applications.
Let’s move beyond theory. Some of these strange and thrilling use cases of medical textiles are:
1. Antibacterial Uniforms
- The members of hospital staff use textiles impregnated with silver or zinc ions.
- These ions kill bacteria on contact and hence lower the risk of infections.
2. Smart Wound Dressings
- There are bandages nowadays that are coloured to turn if the wound is infected.
- Others carry drugs into the area of wound.
3. Implants That Disappear
- Some of these surgical meshes and sutures are designed in order to biodegrade after healing – no need for second surgery.
4. Electrospun Nanofibres
- These are ultra-thin fibres that contain the structure of skin.
- Applied in the superior wound care, drug delivery, and even as scaffold to grow new organs.
5. Textiles in Space Medicine
- Many of the textile materials that NASA makes use of are some of the most sophisticated – in fact, many of those were originally designed for purposes of medicine on Earth!!
India’s Emerging Role in the Medical Textiles
Medical textile manufacturing is on a rapid increase in India becoming a leader in such.
- Coimbatore, Surat, and Ludhiana are the emerging centres for manufacturing nonwoven PPE and masks.
- Institutions such as DRDO, NIFT, IITs and Textile Research Associations are catalysing MedTech revolution.
- India shifted from being a net importer of PPE to becoming the second-largest manufacturer in the world during the COVID-19 – all owing to textile innovation!
What’s Next? Future of Medical Textiles
Medical textiles and their future are not bright but smart, sustainable, and super advanced. Here’s what we can expect:
- Wearable monitors of health – Clothes that monitor your heartbeat, your blood sugar, or your water levels.
- Textile scaffolds for the growth of organ – Assisting to regenerate skin, bone, and even nerves.
- Self-healing bandages – Based on natural concepts, these bandages can be fixed on their own if torn.
- AI-incorporated hospital bedsheets – That monitor patient’s vitals and sends alerts.
- Green medical textiles – Differ in that they are made from plant-based fibres that decompose in an environment friendly manner.
