Introduction
Food, shelter and clothing are the basic needs of everyone.
All clothing is made from Textiles and our shelters are made more comfortable
and attractive by the use of textiles. Textiles have such an important bearing
on our daily lives that everyone needs to know something about them. From
earliest times, people have used textiles of various types for covering or
modesty, warmth, personal adornment, to display personal wealth and even for
biomedical and technical purposes.
A study of textiles will show, for example why certain
fabrics are more durable and serviceable for specific purposes. Complete
knowledge of textiles will facilitate an intelligent appraisal of standards and
different qualities of textile products.
The word "textiles" comes from the Latin term textere,
"woven". Today the word textile is more generalized to refer to product made
from fibres.
A "fibre" is defined as any product capable of being woven
or otherwise made into a fabric. It may be thought of as the smallest visible
unit of textile production 'or' a fibre can be defined as a pliable hair like
strand that is very small in diameter in relation to its length. Fibres are the
fundamental units or the building blocks used in the making of textile yarns
and fabrics.
Where as "yarns" are produced by twisting or spinning of the
textile fibres and in turn a fabric is a planar structure produced by
interlacing or interloping of yarns.
Classification of Textile Fibres:
The textile industry uses many fibres as its raw materials.
As a result of the development of new fibres, difficulties arise in textile
industry in terms of identification, classification. Hence, classification of
textile fibres was compounded by the trained manufactures to identify each of
the fibres with the different trademarks. Textile fibres are classified
according to the source and the length of the fibres.
