WHAT IS YARN? All fabrics- except plastics and non-woven’s- depend upon the use of yarns. A yarn is an assemblage of fibers that are laid or 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 fibbers need little or no twist to hold them together in yarns. The type and length of fiber, the type, ply, and size of yarns and the amount of twist given to yarns determine many of the characteristics of fabrics made from the 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.
