Metal-foil and metal-coated yarns are characterised by a flat ribbon-shape with knife-slit edges. They remain, however, essentially decorative materials and their applications are restricted to this type of use. Metallic fibres of this type are now widely used in the textile industry, and are produced in a range of colours and forms by many manufacturers. Coloured pigments may be added to the adhesive used in sticking the plastic films to the metal foil or metallized film. They retain the glitter of the metal during prolonged periods of use, and have a soft, pleasant handle. The multicomponent filaments produced by slitting sandwich materials of this type are stronger and more robust than the filaments cut from metal foil alone. The metal of the filament is now sandwiched between layers of plastic, which protect it from the atmosphere and from other corrosive influences. In recent years, the ribbon filament of metal has undergone a transformation, which has changed the commercial outlook, for this ancient product. The filaments are weak and inextensible, and are easily broken during wear they lack the flexibility that is essential in a genuine textile fibre. as tinsel, but they remain an essentially decorative material. Ribbon-filaments are now manufactured in considerable quantity, e.g. The development of modern techniques of surface-protection has brought cheaper metals into use aluminium foil, for example, may be anodized and dyed before being slit into filaments which are colourful and corrosion-resistant. Apart from gold, the metals would tend to tarnish, the sparkle being dimmed with the passage of time.ĭespite these shortcomings, the metallic ribbon-filament has remained in use for decorative purposes right up to the present day. They were expensive to produce they tended to be inflexible and stiff, and the ribbon-like cross-section provided cutting edges that made for a harsh, rough handle they were troublesome to knit or weave, and they had only a limited resistance to abrasion. The filaments were used entirely for decorative purposes, providing a glitter and sparkle that could not be achieved by other means.Īs textile fibres, these metal filaments had inherent short comings which restricted their use. These metal filaments were made by beating soft metals and alloys, such as gold, silver, copper and bronze, into thin sheets, and then cutting the sheets into narrow ribbon-like filaments. Thus, metallic fibres are: fibres produced from metals, which may be alone or in conjunction with other substances. Federal Trade Commission and is defined as: A manufactured fibre composed of metal, plastic-coated metal, metal-coated plastic, or a core completely covered by metal. The generic term “metallic” was adopted by the U.S. The term metallic fibre, in its general sense, means simply a fibre that is made from metal. ![]() Thus knitted fabrics are flexible and extensible and metal wire possess properties which are advantageous in technical textile with regard to their permanent antistatic behavior, known conductivity, shielding from electro magnetic field & resistance to cutting. However, combination of knitted structure, textile and metal yarn of wire make it possible to create innovative products for multipurpose technical application. Many technical applications demand properties which cannot be obtained by simply processing common textile material into single textile fabric. ![]() Various methods have been developed to coat fibers and textile materials by metals. These materials have high electrical conductivity and radar reflecting property, yet are lightweight and flexible. With the advancement of technology, metal/conductive textiles found extensive functional applications. The metal threads were twisted, doubled or wrapped around some other thread such as cotton. The Persians made fabulous carpets with gold thread and the Indians, ornamental sarees with it. These were the first ‘man made’ fibres, which came thousands of years before nylon or rayon. Gold and silver were hammered into extremely thin sheets, then cut into ribbons and worked into fabrics. Metallic yarns or threads, in general, have been known for more than 3000 years. ![]() This paper reviews the different types of metallic fibres and their production. All that glitters may not be gold and the ‘zari’ (metallic yarn), responsible for this lustrous appearance, may or may not contain any gold. ![]() The hallmark of all Indian festivities is the golden glitter of the sarees and similarly-adorned dresses worn on such occasions.
