Newer textile fibers & their applications

  1. 1. 04-03-2012 Abstract….  As a famous Scandinavian economist said, “It is very dangerous to make predictions, particularly about the future!”  It is in this sprit that the predictions are made.  New science can produce products beyond our present perceptions. Such innovations are discussed in this paper, citing those are Bio-Degradable and High Performance Fiber & High Functional Fiber .  Now research and development make fibers were used Aravin Prince Periyasamy in high tech applications namely, Medical Textiles, Dept of Textiles, DKTE TEI, Ichalkaranji, MH, India Industrial Textiles, In Defense Textiles, Advance aravinprince@gmail.com Composites, Power Saving And Etc. 1 2Introduction  From the year 1985 onwards textile research was switched over in the direction of developing new fibers especially Hi-Performance fiber and bio degradable to meet the challenges. High Performance Fiber &  With the invent of Hi- Performance fiber and bio degradable fibers the spectrum of application of fibers High Functional Fiber and textile materials were substantially widened.  High-Technology namely new fibers and can be split into two categories viz. - High Performance Fiber & High Functional Fiber and - Bio- Degradable Fibers 3 4 1

  4. 4. 04-03-2012Super Polyethylene Fiber Micro Fiber  Micro denotes man – made fibers which are finer DSM (Netherlands) developed very high tenacity high than any conventional fiber First used in functional modulus polyethylene fiber even higher than Kevlar sportswear. with the help of gel spinning technique.  Micro fibers are usually made of polyester, The method involves both spinning and drawing in polyamide or acrylic – with liters in the range of 0.5 which is a dilute solutions of high molecular weight to 1.2 dtex (1dtex, meaning that one gram of fiber is is extruded into water to form a gel like soft fiber. 10,000 meters long). Which is then heated and drawn out about 30 times  Microfibers clothing is not sensitive retaining its in original length. positive qualities after washing our cleaning. 13 14Power Fibers Perfumed Fibers Heat – regenerating fibers are produced form ceramic composites by applying heat insulation processing technology which utilizes the far intra – red radiations  The perfumed fiber Esprit De Fleurs produced by effect of ceramics when heated, ceramics radiation far kanebo was First exhibited in 1987. infra – red radiation which penetrates into the material and heats it homogeneously by activating molecular  It is made up of fibers to which resin – made motion zirconium, magnesium oxide or iron oxide can microcapsules of 5-10m in diameter containing be blended into synthetic fibers because these perfume essence are bound when the materials radiate Ca 60 MW far infracted of microcapsules are pressed and broken, the perfume wavelengths 8-14 m at a body. is released. . The insulating efficiency plays vital role to suppress  The Esprit de fibers can be used in scarves, T- the consumption of oxygen stored in muscles. shirts, handkerchiefs, hand knitting wools, stocking 15 etc. 16 4

It consists of there polypeptide chains food industry, pharmaceuticals and textiles. arranged in triple chain helix. Alginate name come from „algin‟.  These triple- chain helixes Assembles in to micro fibrils and then fibrils. The unique properties of alginate and its  Collagen has an excellent biocompatibility which derivatives have found applications where makes it a popular choice as a major component of thickening, suspending, emulsifying, and artificial issue and would dressing. stabilizing and gel formation is required.  Collagen products such as sutures can readily be accepted by body because of their low immunogenicity 19 20 5
  6. 6. 04-03-2012Bacterial Cellulose Poly Lactic Acid (PLA)• Bacteria produce cellulose called bio- cellulose or bacterial cellulose. Plant cellulose and bacterial cellulose have the same chemical structure, but different chemical and physical properties.  PLA minimizes environmental waste, as it may be fully biodegraded by microorganisms under This bacterial strain produces a gel like material appropriate conditions into carbon dioxide and containing fine cellulose fiber, which is too thin. water. It is used as an artificial blood vessel for  Biodegradable synthetic fibers and natural microsurgery.

Spider silk is also waterproof, and doesnt break at temperatures as low 25 as -40C. 26Spider Silk Conclusion The high-tech fibers can be specific properties to make them useful as industrial materials. Application of these fibers in high technology area, including the aero/space industry, the transportation industry , the marine industry ,the civil engineering and construction industry and the sports industry ,medical textiles. Now days, almost in all the fields‟ fibers are used. Fibers can replace even metals, so enormous developments are done in fiber field. The bio- fibers are environmental friendly fibers so it has been more demand in future.! 27 28 7
