Man-made fibres are the twentieth-century addition to the range of natural
fibres used to make yarns and fabrics.
These fibres include those made from natural substance, such as acetate, as
well as, synthetics mode from chemicals. Synthetics are cheap to produce and
have easy care properties unlike many of the natural fibres which crease and
shrink badly and need careful laundering.
However, they are less comfortable to wear and most of them lack the
distinctive appearance of wool, silk, linen and cotton. Many modern fabrics are
made from blends of natural and synthetic fibres to give the best of both worlds.

MODERN MAN-MADE FIBRES

MODERN MAN-MADE FIBRES
New scientific developments in man-made fibres led the production of
fibres with pre-determined properties. This has been achieves due to
development of composite materials. A composite material (also called
a composition material or composite) is a material made from two or more
constituent materials. When combined, they produce a material with
characteristics different from the individual components. The new material may
be preferred for many reasons: due to their being stronger, lighter, or less
expensive when compared to traditional materials.
Another new development are plastics. They consist of any of a wide
range of synthetic or semi-synthetic organic compounds that are malleable and
so can be molded into solid objects. The word plastic derives from the Greek
53

plastikos meaning "capable of being shaped or molded". The plasticity, or
malleability, of the material during manufacture allows it to be cast, pressed,
or extruded into a variety of shapes, such as films, fibers, plates, tubes, bottles,
boxes, amongst many others. Due to their low cost, ease of manufacture,
versatility, and imperviousness to water, plastics are used in a variety of
products.
In their search of very strong materials scientists turned their attention to
carbon fibers. They are fibers about 5–10 micrometres in diameter and
composed mostly of carbon atoms. To produce a carbon fiber, the carbon atoms
are aligned parallel to the long axis of the fiber and bonded together. Several
thousand carbon fibers are bundled together to form a tow, which may be used
by itself or woven into a fabric. For the first time carbon fibres were produced
in 1860. But a new interest in carbon fibres revived in the USA and Japan in the
middle of the XX century. A joint technology agreement allowed American and
Japanese scientists to make further headway in this field. Now estimated global
demand for carbon fiber market is $1.7 billion with estimated annual growth of
10-12%.The strongest demand for carbon fiber comes from aircraft and
aerospace, wind energy, as well as the automotive industry. The main
advantages of these fibers include high stiffness, high tensile strength, low
weight, high chemical resistance, high temperature tolerance and low thermal
expansion. These properties have made carbon fiber very popular. Carbon fibers
are also combined with other materials to form composites with a very high heat
tolerance.

METALLIC, GLASS AND RUBBER FIBRES
1. Translate the text
Refined filaments, or wires, of gold, platinum, silver and other metals as
well as of glass and rubber are also considered to be man-made because the
refined metal must be produced into filamentous form.
Metallic Fibres. Centuries before fibres were produced by chemical
processes, ribbon-like metallic threads were used in hand weaving of carpets
and clothing fabrics. The metallic threads produced highly prized decorative
effects, but gold was expensive and all other metals tarnished in use. The
modern metallic filaments and yarns are inexpensive and do not lose their bright
appearance. Metallic filaments are used for decorative effects in fabrics, the
most impressive example of them being embroidery. At one time it was worn
and used also by the nobility in practically all countries. It is also undeniable
that a taste for embroidery is reviving in Europe. The most common type of
embroidery worn by the rich is called goldwork. The term "goldwork" is used
even when the threads are imitation gold, silver, or copper. The metal wires
used to make the threads have never been entirely gold; they have always been
gold-coated silver or cheaper metals. Goldwork is always surface embroidery,
that is, the gold threads are held onto the surface of the fabric by a
second thread, usually of fine silk.
Glass fibres are made by spinning melted glass of a special composition
consisting of silica sand, limestone, soda ash, boric acid, feldspar and fluorspar.
The molten glass is forced through small holes. The hot strands are gathered on
a rapidly revolving carrier that stretches the fibres into fine, flexible filaments.
Glass fibres are tremendously strong and heat resistant but have little stretch.
Glass-fibre fabrics are used when heat and fire resistance are important, as in
draperies for public places. They are also used as reinforcement for laminated
plastics.
Rubber fibres are made from natural or synthetic rubber. They are useful
because of their high elasticity and stretch. They are usually employed as a core
around which other fibres or yarns are wound to protect the rubber from
57

abrasion. They are used in foundation garments, surgical supports and elastic
webbing.

ADDITIONAL READING
A textile is a flexible material consisting of a network of natural or
artificial fibres (yarn or thread). Yarn is produced by spinning raw fibres
of wool, flax, cotton, hemp, or other materials to produce long strands. Textiles
are formed by weaving, knitting, knotting, or felting.
The related words fabric and cloth are often used in textile trades (such
as tailoring and dressmaking) as synonyms for textile. However, there are subtle
differences in these terms in specialized usage. A textile is any material made of
interlacing fibres, including carpeting and geotextiles. A fabric is a material
made through weaving, knitting, or bonding that may be used in production of
further goods (garments, etc.). Cloth may be used synonymously with fabric but
is often a piece of fabric that has been processed.
The word 'textile' is from Latin, from the adjective textilis, meaning
'woven', from textus, the past participle of the verb texere, 'to weave'. The word
'fabric' also derives from Latin, and earlier as the Latin fabrica 'workshop; a
skilful production, structure, fabric', which is from the Latin faber, or 'artisan
who works in hard materials'.
Textile fibres can be created from many natural sources (animal hair or fur,
insect cocoons as with silk worm cocoons), as well as semisynthetic methods
that use naturally occurring polymers, and synthetic methods that use polymerbased materials, and even minerals such as metals to make foils and wires. The
textile industry requires that fibre content be provided on content labels. These
labels are used to test textiles under different conditions to meet safety
standards (for example, for flame-resistance), and to determine whether or not a
textile is machine washable or must be dry-cleaned. Common textile fibres used
in global fashion today include a lot of natural and man-made fibres.
Fiber or fibre (from the Latin fibra) is a natural or synthetic substance that
is significantly longer than it is wide. Fibers are often used in the manufacture
of other materials. The strongest engineering materials often incorporate fibers,
for example carbon fiber and ultra-high-molecular-weight polyethylene.
Synthetic fibers can often be produced very cheaply and in large amounts
compared to natural fibers, but for clothing natural fibers can give some
benefits, such as comfort, over their synthetic counterparts.
Natural fibers develop or occur in the fiber shape, and include those
produced by plants, animals, and geological processes. They can be classified
according to their origin:
Vegetable fibers are generally based on arrangements of cellulose, often
with lignin: examples include cotton, hemp, jute, flax, ramie, sisal, bagasse, and
banana. Plant fibers are employed in the manufacture of paper and textile
(cloth).
Wood fiber, distinguished from vegetable fiber, is from tree sources.
Forms include ground wood, lacebark, thermomechanical pulp (TMP), and
