However they are constructed, all textiles are made from yarns
The vast array of textiles available today are expected to serve a hugh variety of purposes,
each requiring a different charactoristic and property.
To ensure that the yarns used to produce these textiles
have the charactoristics and properties appropriate to their end use,
the yarns have to be carefully designed.
Strength, elasticity, extention, handle and feel, abrasion resistance,
plus the visual and aesthetic quality of the yarn
must be appropriate to the end use of the yarn.
Some of these properties will come from the constituent fibres,
others will come from the
way that the fibres are arranged and treated in the yarn structure.
In order to more easily understand yarns
it is nesseccary to break them down into some sort of classification system
All yarns can be divided into one of two categories,
continuous filament yarns or
spun-staple yarns
both staple and filament yarns can then be further subdivided.
