Yarn:
Generally yarn is a continuous strand
which is made up of filament, fibers or materials where the materials are
suitable for knitting, weaving, otherwise forming a textile fabric.
Yarn is an assembly of fibres that are
twisted together to form a continuous strand. Yarns may be made from either
staple fibers or filament fibers. Staple fibers are twisted into yarns;
filament fibres need little or no twist to hold them together into yarns. The
type & length of fibre, the type, ply & size of yarns & the amount
of twist given to yarns determine many of the characteristics of fabrics made
from the yarns. All fabrics except plastics & non-wovens depend upon the
use of yarns. For example, fabrics constructed of spun yarns are less smooth
than fabrics constructed of filament yarns. They also have a lower luster cord
or rib fabrics contain ply or larger yarns in the rib direction.
