Single Yarns: To make these spun yarns, single strands of fibers are held together by twist. They are either given S-twist or Z-twist. Single yarns are used for making most of the fabrics.
Ply Yarns: Two or more strands or yarns are twisted together to make ply yarns. In two-ply yarns, two single strands are twisted together, and three-ply yarn is made up of three single strands and so on. The strands are generally twisted in one direction and then combined and twisted in opposite direction.
Cabled Yarns: Two or more plied yarns are twisted together, usually, around each other continually in the opposite direction of the previous twist. Thus, it may be twisted in an S/Z/S form or a Z/S/Z form These yarns are hard, rough and strong.
Doubled Yarns: In the weaving process, two or more strands are treated as one but they are not twisted together as when making ply yarns. Doubled yarns are used for giving ornamental effects due to their lustre and softness.
Novelty Yarns: For making novelty yarns, decorative effects are produced by giving different amounts of twists while spinning. Sometimes, yarns having different diameters are twisted together to make them. They are used for making ornamental fabrics having various textures and color combinations. There are many types of novelty yarn, each having difference in its making process. These novelty yarns include slub yarns, boucle yarns, spiral yarns, chenille yarns among others.
