Yarn is an assemblage of fibers twisted or laid together to form a continuous strand of suitable thread. Yarn can consist of staple fibers, filaments, or a combination of the two. Filaments merely need grouping in order to produce the thickness of the yarn. Grouping of filaments is achieved by twisting them together. Staple fibers have to be twisted to make them adhere to a continuous length of yarn. With the action of twisting forces, the fiber surfaces into contact with each other setting up friction between them which enables them to withstand tension. Different types of yarn are filament yarn, staple yarn, etc.


A thread is three or more yarns tightly twisted, dyed, and finished to fit into the eye of the needle or to be hand-knotted, crocheted, etc. So it is called sewing thread, mostly used in the apparel industry and anywhere is sewing process required.
