   • Single-use and Reusable Options: Single-use products (such as surgical drapes, gloves, and gowns) reduce the risk of cross-contamination, while reusable products (such as patient gowns) are designed for multiple uses, contributing to sustainability.

2. Biocompatibility:

   • Biocompatibility refers to the ability of a material to interact with the human body without causing an adverse immune response. This is especially important for products like surgical sutures, wound dressings, and implant materials.
   • Minimizing Allergic Reactions: Medical textiles are typically made from hypoallergenic materials that do not trigger allergic responses, which is vital for products in direct contact with the skin or mucous membranes.

3. Breathability and Moisture Management:

   • Quick Moisture Absorption and Evaporation: Medical textiles, such as wound dressings, are designed to absorb excess moisture and facilitate evaporation to prevent infection. This is essential for maintaining a clean and dry environment around wounds or surgical sites.
   • Maintaining Moisture Balance: Advanced wound care products, such as hydrocolloid or hydrogel dressings, help maintain an optimal moisture balance, which promotes faster healing by preventing desiccation and tissue damage.

4. Flexibility and Durability:

   • Flexible Structure: Medical textiles, especially those used in orthopedic support or compression garments, must be flexible to accommodate the body’s natural movements while providing the necessary support.
   • Durability: Surgical gloves, gowns, and other medical textiles must be durable enough to withstand the stresses of daily use without tearing or losing effectiveness. Materials like nitrile and latex are commonly used in medical gloves due to their high durability.

5. Functional Features:

   • Thermal Insulation: Some medical textiles are designed to regulate body temperature, such as heated or cooling garments used for post-surgical recovery.
   • Antibacterial Coatings: Textiles used in wound care or surgical applications often feature antimicrobial treatments to help reduce the risk of infection.
   • Drug Delivery: In advanced treatments, some medical textiles are designed to release controlled amounts of medication, such as pain relievers or antibiotics, over time, directly to the site of treatment (e.g., drug-eluting dressings).

Classification of Medical Textiles

1. Surgical Textiles:

   • Surgical Gowns and Drapes: These are used in surgeries to protect both the healthcare providers and the patients from infections. These textiles must be impermeable to liquids and microorganisms while being breathable.
   • Sterile Covers and Masks: Used during surgeries and other medical procedures, sterile covers protect open wounds and surgical sites, while masks prevent the transmission of airborne pathogens.
   • Additional Information: Surgical masks, in particular, prevent the spread of airborne microorganisms to medical surfaces, reducing the risk of contamination during procedures.

2. Wound Care Products:

   • Wound Dressings and Bandages: These are designed to maintain moisture balance, prevent infection, and accelerate healing. Wound dressings are available in various forms such as non-adherent, absorbent, and occlusive types to suit different stages of wound healing.
   • Antimicrobial Properties: Many wound dressings are treated with antimicrobial agents like silver or iodine, which kill or inhibit the growth of bacteria and fungi.
   • Tissue Regeneration: Some advanced wound care materials, such as collagen-based dressings, support tissue regeneration and reduce scarring.

3. Implantable Textiles:

   • Surgical Sutures: These are made from biodegradable or non-biodegradable materials that are designed for use in closing wounds. Sutures are designed to minimize the risk of infection and promote faster tissue healing.
   • Vascular Grafts and Artificial Organs: Materials for implants must be biocompatible and often mimic the properties of human tissue. Vascular grafts, for example, help replace damaged blood vessels, while artificial organs assist with critical bodily functions like circulation or filtration.

4. Hygiene Products:

   • Single-Use Hygiene Products: Medical textiles such as patient bed covers, sanitary pads, and adult diapers help prevent infections and ensure comfort for patients in hospitals and home care settings.
   • Absorbent Textiles: These products are designed to absorb bodily fluids, such as urine, and are crucial in elderly care, especially for individuals with incontinence.
   • Specialized Pads: Feminine hygiene products and other absorbent textiles are designed to be highly absorbent and odor-resistant, often incorporating antimicrobial materials.

5. Rehabilitation and Assistive Textiles:

   • Orthopedic Support Products: Bandages, knee braces, support corsets, and splints help immobilize and support the body during rehabilitation after injury or surgery.
   • Pressure Therapy Textiles: Compression garments are used for conditions like varicose veins, lymphedema, or post-surgery recovery to improve circulation and reduce swelling.

6. Smart Medical Textiles:

   • Biometric Monitoring: Smart textiles integrated with sensors monitor health parameters such as heart rate, body temperature, and respiration, providing real-time data to healthcare professionals.
   • Drug Delivery Textiles: Smart textiles that release medications directly at the treatment site can enhance the efficacy of therapies such as cancer treatments, providing continuous and controlled medication release.
   • Digital Medical Garments: Some advanced medical textiles are capable of monitoring wound healing progress or body temperature, alerting healthcare providers to potential complications.
