Application of nonwovens in medical field
« on: November 17, 2013, 03:34:34 PM »
Categories of medical textiles

Based on applications the medical textile can be broadly categorised as follows:

    Personal health care/hygienic products: Bedding, clothing, surgical gowns, cloths, wipes surgical curves, surgical hosiery, diapers, etc.

    Non-implantable material or medical dressings & auxiliaries: Wound dressing, bandage, plasters, gauge, lint wadding, etc.

    Implantable materials: Sutures, vascular grafts, artificial ligaments, and artificial joints.

    Extra corporal devices: Artificial kidneys, liver & lungs, etc. The nonwovens are used for the given applications in different forms.

Nonwoven application in medical

The properties of nonwoven fabrics are determined by those of the constituent polymer or fibre and by the bonding process. For instance, expanded PTFE products can be formed to meet varying porosity requirements. Because of the expanded nature of their microstructure, these materials compress easily and then expand—a suture, for example, can expand to fill the needle hole made in a tissue—allowing for tissue in growth in applications such as arterial and patch grafts.

Polyurethane-based nonwovens produce a product that resembles collagen us material in both structure and mechanical properties, particularly compliance (extension per unit pressure or stress). The porosity of both PTFE- and polyurethane-derived nonwovens can be effectively manipulated through control of the manufacturing processes. Hence by controlling the various parameter of nonwoven they can utilise effectively in different applications of medical.

The medical textiles include a vast range of applications, viz, adhesive tapes, bandages, beddings, blankets, castings, diapers, dressings, eye pads, gauzes, protective clothing’s, sutures, surgical covers, surgical clothing’s, swabs, supports, sanitary products, hospital gowns, etc. They also find application in extra-corporeal devices like artificial kidney, liver, heart & mechanical lung, ligaments, vascular grafts, heart valves, blood vessels, artificial skins, etc

A range of natural fibres and biodegradable polymers with non-biodegradable synthetic polymers is being utilised for developing new products in medical textiles. Since the medical textile applications are directly related to the life of human being, those are required to undergo stringent testing and hygienic criteria, which led to innovative use of variety of fibres and a lot of developments taking place in this area.

Use of nanotechnology, tissue engineering, biomaterials along with basic textile structures, viz, fibres, yarns, woven, knitted, nonwoven and braided fabrics and composite structures made it possible to widen the horizon of medical textiles. Especially, innovations in nonwovens have brought a great deal of change in the field of Medicals.

Nonwoven textile scaffolds are used to replace or repair different organs, bones, vascular system and in partial replacement of skin. The article will discuss in detail the recent advances in medical textiles field, which will continue to help improving the life of human being considerably with the aid of nonwoven textiles. The rapidly growing field of biomedical textiles and health care products is truly multi-disciplinary in nature. From ancient times the textile materials were used for medical applications in India and Egypt like surgical sponge, linen and silk sutures and strips, catgut, etc.
