- 2. Medical Textile All textiles used in operative and post-operative tasks in and around a patient and the medical practitioners are termed as medical textiles. These highly specialized and bio-compatible technical textiles used for medical and hygiene applications are called MED-TECH. Medical textiles are one of the most rapidly expanding sectors in the technical textile market. Some of the important field of application of textile in medicine are wound care and preventing chronic wounds. Bandages and wound dressings are most commonly used because they are affordable and reusable. The major characteristics of medical textiles are non-toxicity, non-allergenic and ability and ability to be sterilized. Medical textiles should also have good strength, elasticity, biocompatibility, durability, and flexibility depending upon the product.
- 3. Fibers in Medical Field Natural Fibers Like ( Cotton, wool, silk ) Synthetic Fibers Like ( Polyester, polyamide, polypropylene, polytetrafluoroethylene, glass fiber, carbon fiber, polyglycolide, PVT fiber… etc.)
- 4. Uniqueness of Fibers used in Medical Textiles Pure and Hygienic Bio- degradable Fast and High absorbency Excellent wicking performance Barrier to percolation Good Insulation Good thermal stability High strength Low lint Soft fell Excellent drape ability Breathability Static dissipation Engineered specialties -Anti- bacterial properties -Medicinal clothing
- 5. Properties of the medical textile as follows: Medical textiles must be non-toxic and non-allergenic. It must be compatible with the most living system. It should be sterilized without imparting any change in physical and chemical characteristics. If necessary, it should be versatile in their physical form like powder form, aqueous form, film, fiber, sponges, etc. It should have enough lightness, strength, elasticity, softness, etc.
- 6. Medical Textile Market Segmentation by Type & Application
- 8. Implantable Used in effecting to the body whether it is wound closure (sutures) or replacements surgery like vascular grafts, artificial ligaments.
- 9. Non- Implantable Used for external applications and may or may contact with skin.
- 10. Healthcare & Hygiene Used either in the operation theatre or in the hospital wards for hygiene, care and safety of the staff and patients.
- 11. Extra corporeal Used as mechanical organs that for blood purification and include artificial kidney, the artificial liver and the mechanical lung.
- 12. Non-implantable Materials These materials are used for external applications on the body and may or may not make contact with skin. Some of the common non-implantable materials are wound care fabrics and absorbent pads, bandages, plasters, gauzes, lint, and wadding.
- 13. Wound Care The functions of these materials are to provide protection against infection, absorb blood and exudates, promote healing, and, in some instances, apply medication to the wound. Common wound dressings are composite materials consisting of an absorbent layer held between a wound contact layer and a flexible base material.
- 14. Extracorporeal Devices Extracorporeal devices are mechanical organs that are used for blood purification and include artificial kidneys (dialyzer), artificial liver, and mechanical lungs. The function and performance of these devices have found a facelift with the use of newer fibers and modern textile technology.
- 15. Artificial Kidney / Dialyzers The function of the artificial kidney is achieved by circulation the blood through a membrane, which may be either a flat sheet or a bundle of hollow regenerated cellulose fibers like hollow viscose or hollow polyester fiber in the form of cellophane that retain the unwanted waste materials. The kidney dialysis machine is outside the body and purifies the blood using a filter called Haemon dialyzer.
- 16. Artificial Heart The artificial heart is intended for use in patients whose hearts have been irreparably damaged, and for whom, existing methods of surgical intervention and/or drug therapy are inadequate.
- 17. Artificial Lung The microfibers or the membrane oxy-generator are the technical textile component in this device. The microporous membranes of the mechanical lung possess high permeability to gases but low permeability to liquids and function in the same manner as the natural lung allowing oxygen to come into contact with the patient’s blood.
- 18. Implantable Materials These materials are used in the effective repair of the body whether, like wound closure (sutures) or replacement surgery (vascular grafts, artificial ligaments). Bio-combability is of prime importance. Four key factors determine how the body reacts to the implant. The most important factor is porosity, which determines the rate at which human tissue will grow and encapsulate the implant. Small circular fibers are better encapsulated with human tissue than larger fibers with irregular cross-sections. Toxic substances must not be released by the fiber polymer, and the fibers should be free from surface contaminants such as lubricants and sizing agents. The properties of the polymer will influence the success of the p=implantation in terms of its biodegradability.
- 19. Artificial Ligaments An artificial ligament is a medical device for joining the ends of two bones. The artificial ligaments are made from man-made fibers like polyester. The artificial ligament is a multi-layered or tubular woven structure having an intra-auricular region, with at least one bend and end region. Each region is woven to possess the required flexibility and strength.
- 20. Artificial Skin Skin grafting is the procedure of replacing dead skin with live skin. After removing burnt/damaged skin, surgeons blanket the wound with a covering (artificial skin) before applying a skin graft on top of this bio-material to encourage the growth of new skin to close the wound. Artificial skin consists of two layers. The bottom layer, which is designed to regenerate the lower layer of real skin, is composed of a matrix of inter- woven bovine collagen( a fibrous cow protein) and a sticky carbohydrate (sugar) molecule called glycosaminoglycan, which mimics the fibrous pattern of the bottom layer of skin. This matrix then sticks to a temporary upper layer: a medical-grade, flexible silicone sheet that mimics the top, the epidermal layer of skin.
- 21. Artificial Cornea The cornea is the transparent front portion of the eye that permits light to enter the eye. Normally crystal clear, it can become cloudy or misshapen, causing reduction in vision or blindness. The polymers used in artificial cornea need to be biocompatible, flexible, sufficient mechanical strength. The characteristics require for textiles used in the making of the artificial cornea are to withstand pressure, be transparent, have appropriate curvature, and have a suitable refractive index, sufficient tensile strength to allow surgical manipulation and fixation, scratch resistance.
- 22. Healthcare/Hygiene products Healthcare and hygiene products are an important sector in the field of medicine and surgery. They are used either in the operating theatre or on the hospital ward for the hygiene, care, and safety of staff and patients.
- 23. Diapers Baby diapers are used to absorb and retain the body fluids of infants in periods between birth and 24 months. The technical textile component of the diaper is the non-woven fabric which prevents fluid leakage and gives the diaper the desired shape. Super absorbent polymer to ensure complete dryness and prevent growth of bacteria The non-woven inner layer should be hydrophilic and absorb fluids fast The cover should be breathable Optional, leg guards to prevent leakage
- 24. Sanitary Napkin A sandwich of an absorbent pad between fabric sheets essentially makes sanitary napkins. The technical textile component of these napkins is the non-woven fabric which prevents fluid leakage. The non-woven fabric is made up of 10-20 GSM and accounts for around 11-12% by weight of the sanitary napkin around 0.95 to 1 gram per napkin. The super absorbent polymer ensures complete dryness Hydrophilic non-woven to absorb fluids fast Snug fit Breathable cover
- 25. Surgical Disposables The surgical disposables primarily consist of masks, capes, drapes, gowns, covers, and shoe covers made of polypropylene spun-bond fabric (non-woven) with or without polyethylene film. Surgical disposables are used in hospitals and pharmaceutical companies to maintain hygienic and sterile operations. These are called surgical disposables as they are for one-time use and later disposed of. High barrier to blood or body fluids Lower lint (lint is a source of infection) Proven sterilization performance Comfort and breathability Good bacteria filtration efficiency Breathing resistance

- 27. Opportunity for Bangladesh in the field of medical textiles Bangladesh is the most populous country in the world with a huge requirement for healthcare services. The opportunity in the medical textile industry is also tremendous. Consumption is increasing rapidly. The healthcare spending from the private sector comprises over 70% of the market which is more than comparable developing countries as well as developed countries. The Coronavirus impact has revealed the weakness and vacuum of medical safety kits all over the world. Here the Bangladeshi manufacturers can think over it and can take this as an opportunity for the long run. Regular fashion brands are canceling their orders, at the same time PPE demand growing sky high all over the world. So, factories can immediately manufacture this demand-based PPE also can-do plan for future business. Right now there are a few manufacturers who are supplying medical accessories to several countries.
- 28. Medical textile manufacturers in Bangladesh Smart Group of Industries Nasir & Sons Bangladesh E-Baik Transport Corporation Abiyan International Sagar Trader’s These manufacturers of Bangladesh supplying regularly their products in many countries such as the USA, Malaysia, Pakistan, India, Lebanon, Sri Lanka and Nigeria. There are now many more factories like Snowtex, Urmi Group, Aman Group, Dekko Group, etc. are producing personal protective equipment (PPE) to meet the current local demand.
- 29. Export Figure of Bangladesh’s Medical Textiles in Corona Epidemic Corona has changed the image of the export of health care products. Mask exports from March to July amounted to $2.68 core, up from only $26lakh in the same period last year. On the other hand, PPE, Apron and Surgical gowns exports have been $35 core 15 lakh. Of that, PPE exports in July and August alone were USD 13 crore. In the last few months, materials worth USD 50 core 10 lakh have been shipped to the United States, the United Kingdom, Canada and the European Union.
- 30. Conclusion The importance of medical textiles in human life, healthy living and improvement is immense. The development of new technologies and new items will help patients to overcome the hardships that they used to suffer in the past. But the sad thing is that even though there is research on Medi-Technology in developed countries, there is not much research in Bangladesh. There are many more unknown areas of medical textiles, we should do research on those issues. We should pay more attention to the production of healthy and quality medical textile materials. In addition to technology, we need to keep an eye on the price of our products. Through this it will be possible to produce quality complete and readily available modern medical textiles.
