Yarn

Generally yarn is a continuous strands which is made up of filament, fibres 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 fibres or filament fibres. Staple fibres 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 lusture cord or rib fabrics contain ply or larger yarns in the rib direction.
