1. Agrotech Agriculture has been amongst the most primal occupations of the humankind and is still a major industry, globally. In this era of modernization and high technological advancements, it has spread its horizons and started using man-made, non-conventional textiles, called “technical textiles”. Tapping the potential of technical textiles and putting their vital properties to an advantage; agriculture, horticulture, forestry and fishing segments (all the four sectors combined together are popularly called as “Agrotech” sector) are increasingly using them for equipment development and other applications. This textile sector comprises of all textiles that are used in growing, harvesting, protection and storage of either crops or animals. It includes diverse items such as fishing nets and fish-lines, ropes, shade fabrics, mulch mats, woven and non-woven covers for crops, bird protection nests, etc. These textiles are driving the sector profitably by improving the productivity and reducing the need for chemicals. 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

7. Medtech Due to astounding technological developments, techincal textiles are extensively used in the healthcare industry today. In the field of medical application, technical textiles are not just used in contact with the skin, but also fulfill important functions within the body (intra-corporal applications like implants). Technical textiles offer medical and hygiene industry with unparalleled protection, comfort and cost saving. These highly specialized and bio- compatible technical textiles, used for medical and hygiene applications are called “MEDTECH.” The characteristics required of MEDTECH vary depending on the task for which they are to be used. Some applications demand a protective function, others a high absorptive capacity and some other others impermeability. Special antimicrobial finishes are an important characteristic of these textiles Depending on the nature of application, most of the medical products are disposable in nature and are made of nonwoven fabrics. In global markets disposables are fast replacing non-disposable health care textiles. 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

7. Medtech Some areas of usage are: Healthcare/ hygiene products- Include bedding, clothing, surgical clothes, products for feminine hygiene like sanitary napkins, baby and adult diapers ,surgical gown clothes, filters, bandages, support and protective material, surgical sutures etc. Non-implantable materials- For wound care that includes absorbent pad (wound contact layer, base material viscose, plastic film) and bandages (simple inelastic/elastic, orthopaedic, plasters, gauzes, lint, padding) Textiles in Extracorporeal devices- Like artificial kidney, liver and lungs. Implantable materials- Like sutures (biodegradable and non-biodegradable), soft tissue implants, artificial tendon (meshes), artificial ligament, artificial cartilage, orthopedic implants artificial joint, cardiovascular implants vascular grafts, heart valves. 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

Medical Textiles Definition: A general term which describes a textile structure which has been designed and produced for use in any of a variety of medical applications, including implantable applications. An important and growing part of the textile industry is medical, hygene and health sector. The extent of growth is due to the development and improvement of knowledge in both textile as well as medical sector. The engineering approach to develop textile products that will be suitable for medical and surgical application should possess a combination of the following properties e.g. strength, flexibility, and sometimes moisture and air permeability. Materials include natural fibre, monofilament as well as multifilament yarns. The number of application is huge and diverse, ranging from a single thread suture to the complex composite structures for bone replacement, and from the simple cleaning wipe to advanced barrier fabrics used in operation rooms. Thus the textiles used in medical and surgical purposes can be classified as follows; Nonplantable materials-Wound dressing, bandages, plasters etc. Extracorporeal devices- artificial kidney, liver, and lung Implantable materials-suture, vascular grafts, artificial ligaments, artificial joints, etc. Healthcare/hygine products-bedding, clothing, surgical gowns, cloths, wipes etc. The majority of the healthcare products are disposable while some are reused. The medical product based on textiles is around $ 76 billion in the year 2000. 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

Medical Textiles Fibres used Fibres used in medical application may be classified as follows; 1. According to source of origin Natural- Cotton and silk most widely used Synthetic- Viscose, polyester, polyamide, polytetrafluoroethylene (PTFE), polypropylene, carbon, glass, and so on. 2. According to biological resistance Biodegradable- Fibres which are absorbed by the body within 2-3 months time after implantation and include Cotton, Viscose rayon, polyamide, polyurathene, collagen, and alginate, polycaprolactone, polypropiolactone. Non biodegradable-Fibres that are absorbed by the body slowly and take more than six months time to degrade are considered as non biodegradable. Non-biodegradable fibres and include polyester (e.g. Dacron), polypropylene, PTFE and carbon. Fibre used in medical textiles must fullfill the following criterion the fibres must be nontoxic must be non-allergenic must be non-carcinogenic must be able to be sterilised without imparing any change in their physical or chemical characteristics. where necessary biodegradable where necessary non biodegradable 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

Medical Textiles Fibre used: Traditionally cotton, silk and viscose have long been used for medical and surgical purposes. One such area of application is wound care, where moisture and liquid exude from the wound is absorbed by the fibrous structure to promote healing in relatively dry conditions. However upon healing small fibrous elements protruding from the wound dressing are usually trapped in the pores of the newly formed tissues which make their removal distressing to the patients. Research show that wound under moist condition would in fact heal better and faster, which would also remove the problem of fibres being trapped in the healing wound. The concept of moist healing has since been responsible for the development of many fibres which have vastly improved wound management techniques and patient care. A variety of polymers such as collagen, alginate, chitin, chitosan have been used to be essential materials for modern wound dressings. Collagen which has been obtained from bovine skin is used to produce biodegradable fibres used as suture which is as strong as silk. The fibre can also be converted to transparent gel like film structure used as contact lens which has very good oxygen permeability. Alginate (obtained from sea weeds) and chitin (obtained from shrimp shells) are widely used for treatment of wound healing. Chitin nonwoven fabric is used as artificial skin. 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

Non-implantable materials
4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

A. Nonplantable materials
These materials are used for external application on the body and may or may not make contact with skin. The following table illustrates a range of materials used as non-implantable madical textiles. (i) Wound care products– The purpose of these products are to provide protection against infection, absorb blood and exudates, promote healing and in some instances apply medication into the wound. Common wound dressings are composite materials consisting of an absorbent layer held between a wound contact layer and a flexible base material. The absorbent pad absorbs blood or liquids and provides cushioning effect to protect the wound. The wound contact layer should prevent adherence of the dressing to the wound and be easily removed without disturbing new tissue growth. The base materials are normally coated with acrylic adhesive to provide the means by which the dressing is applied to the wound. The use of collagen, alginate, and chitin fibres contribute significantly to the healing process. When alginate fiber is used as wound contact layer the interaction between the alginate and the exuding wound creates a sodium alginate gel which is hydrophilic and permeable to oxygen and impermeable to the bacteria and contribute to the formation pf new tissue. 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

(ii) Gauze- It is an open weave absorbent fabric, when coated with paraffin wax is used for the treatment of burns and scalds. In surgical application gauze serves as an absorbent material. (iii) Lint- It is a plain weave cotton fabric that is used as protective dressing for first aid and mild burn application. (iv) Wadding-It is a highly absorbent material that is covered with a nonwoven fabric to prevent wound adhesion or fibre loss. (v) Bandages- Bandages are designed to perform a whole variety of specific functions depending upon the final medical requirements. They can be -woven, -knitted, -or nonwoven and are -either elastic or nonelastic. 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

the most common application of bandages is to hold the dressing in place over wound. These are light weight knitted or woven fabrics made of cotton or viscose –scoured, bleached and sterilized. Elasticized yarns are incorporated to the structure to impart support and conforming characteristics. Knitted bandages are produced either in weft knitting machine to produce tubular fabric of varying diameter or in warp knitting machine. Woven light support fabrics are used in the management of sprains or strains and the elasticated properties are obtained by weaving crepe yarns having a very high twist. Similar properties can also be obtained by weaving fabric from two warp beam one in low tension and the other in high tension. Compression bandages are used for the treatment and prevention of deep vein thrombosis, leg ulceration, and varicose veins and are designed to exert a required amount of compression on leg when applied at a constant tension. Compression bandages are classified by the amount of compression they can exert at the ankle and include extra –high, high, moderate and light compression can be either woven and contain cotton and elastomeric yarns or warp and weft knitted in both tubular or fully fashioned forms. Orthopaedic cushion bandages are used under plaster casts and compression bandages to provide padding and prevent discomfort. Nonwoven orthopedic cushion bandages are produced from polyurathene foam, polyester, or ploypropylenefibres and contain blends of natural or synthetic fibres. Non woven bandages are lightly needle punched to maintain bulk and loft. 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

B. Extracorporeal devices-
These are mechanical organs that are used for blood purification and include the artificial kidney (dialyser), the artificial liver, mechanical lung. The function and performances of these devices benefit from fibre and textile. The function of artificial kidney is achieved by circulating the blood through a membrane, which may be either a flat sheet or a bundle of hollow regenerated cellulose fibres in the form of cellophane that retain the unwanted waste materials. Multilayred filters composed of numerous layers of needle punched fabrics with varying densities may also be used and are designed to remove the waste materials rapidly and efficiently. The artificial liver utilizes hollow fibres or membranes similar to those used in artificial kidney to perform high permeability to gases but low permeability to liquids and function in the same manner as in the natural lung allowing oxygen to come into contact with the patient’s blood. 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

B. Extracorporeal devices-

C. Implantable materials-
These materials are used in effecting repair to the body whether it be wound closure (Sutures) or replacement surgery (Vascular grafts, artificial ligaments etc.). Table 15.3 show the list of implantable materials. Biocompatibility is of prime importance if the textile materials are to be accepted by the body and four key factors will determine how the body reacts to the implant, these are as follows The most important factor is porosity which determines the rate at which human tissue will grow and encapsulate the implant. Small circular fibres are better encapsulated with human tissue than larger fibres with irregular cross section. Toxic substances must not be released by the fibre polymer, and the fibres should be free from surface contaminations such as lubricants and sizing agents. The properties of the polymer will influence the success of the implantation in terms of its biodegradability. Polyamide is the most reactive material losing its overall strength after only two years as a result of biodegradation. PTFE is the least reactive with polypropylene and polyester is in between 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

9. Oekotech Environmental threats loom large on almost every nation in the world today. With this threat gaining its stature day by day, Eco Textiles gain utmost importance as one of the most useful resources that help promote new innovations, in an eco-friendly manner. OEKTECH is the term used for technical textiles that are used for environmental protection. It stands for new ideas and interesting concepts in the area of environmental protection, waste disposal (including innovative filtration media) and new recycling technologies. It is opening up new avenues for environmental engineers, safety engineers and personnel in environmental protection agencies. These eco- friendly textiles provide a range of environmentally responsible alternatives to other resource hungry materials. They tap into both post-consumer and post-industrial waste streams & scrap and reuse them for manufacturing an extremely durable and eco-friendly textile. They not only lead to reduction of waste but also more importantly, save the rapidly depleting natural resources. 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)

10. Packtech Packaging textiles include all textile packing material for industrial, agricultural and other goods. The demand for packing material is directly proportional to economic growth, industrial production and trade as goods are produced and then distributed both locally and internationally. The growing (environmental) need for reusable packages and containers is opening new opportunities for textile products in this market. Sacks and bags made of traditional jute, cotton or natural fiber are gradually casting way for modern synthetic fibers. These technical textiles, used in packaging and subsequent transportation are called “PACKTECH.” It is well known that these fabrics are ideal for many kinds of packaging. At one end, PACKTECH includes heavyweight, dense woven fabrics (used for bags, sacks, flexible intermediate bulk carriers and wrappings for textile bales and carpets) and on the other end, it includes lightweight non wovens used as durable papers, tea bags and other food and industrial product wrappings. ations 4/20/2017 Compiled by: Dewan Murshed Ahmed (DMA)
