The yarn contains fibers which
remain in extended state individually. By twisting, the yarn along with fibers
is contracted and its mass per unit length increases. Again by de-twisting, the
filament of yarn gets extended. For staple fiber yarn, this phenomenon is
called contraction and for filament yarn, this is called twist retraction.
