Definition of fiber

DEFINITION OF FIBER

A textile or cloth is a flexible woven material consisting of a network of natural or artificial fibres often referred to as thread or yarn. Yarn is produced by spinning raw fibres of woolflaxcotton, or other material to produce long strands.Textiles are formed by weavingknittingcrocheting,knotting, or pressing fibres together (felt).
The words fabric and cloth are used in textile assembly trades (such as tailoring and dressmaking) as synonyms for textile. However, there are subtle differences in these terms in specialized usage. Textile refers to any material made of interlacing fibres. Fabric refers to any material made through weaving, knitting, spreading, crocheting, or bonding that may be used in production of further goods.Cloth may be used synonymously with fabric but often refers to a finished piece of fabric used for a specific purpose.

History
The discovery of dyed flax fibres in a cave in the Republic of Georgia dated to 34,000 BCE suggests textile-like materials were made even in prehistoric times.
The production of textiles is a craft whose speed and scale of production has been altered almost beyond recognition by industrialization and the introduction of modern manufacturing techniques. However, for the main types of textiles, plain weavetwill, or satin weave, there is little difference between the ancient and modern methods.
Incas have been crafting quipus (or khipus) made of fibres either from a protein, such as spun and plied thread like wool or hair from camelids such asalpacasllamas, and camels, or from a cellulose like cotton for thousands of years. Khipus are a series of knots along pieces of string. Until recently, they were thought to have been only a method of accounting, but new evidence discovered by Harvard professor Gary Urton indicates there may be more to the khipu than just numbers. Preservation of khipus found in museum and archive collections follow general textile preservation principles and practice.
During the 15th century, textiles were the largest single industry. Before the 15th century textiles were produced only in a few towns but during they shifted into districts like East Anglia, and the Cotswolds.
Fiber (American English) or fibre (International english ) is elongated stringy Natural , man-made or synthetic material. In the case of natural fibers, they often tie together the parts of natural creatures. Natural Vegetable fibres generally consist of cellulose, examples include cotton , linen and hemp. Cellulose fibers are used in the manufacture of paper and cloth . Natural Animal fibre include spider silk , sinew, hair, and wool .There are naturally occurring mineral fibre such as Asbestos .


Man-made fibres are those that are made artificially, but from from natural raw materials (often cellulosic ). Examples include Fiber glass , rayon , acetate cupro and the more recently developed Lyocell .Synthetic fibres include nylon , acrylic , polyester and graphite fibre .
