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.
