Yarns are made by twisting fibers to form an interlocked continuous length. This process is known as spinning which is carried through various spinning machines like ring spinning machines
and open-end spinning machines. Although there are various spinning methods, the basic processes included in them remain similar that are carding, combing, drafting, twisting and winding. They are all done with the help of specialized machines like carding machines
, winding machine
and yarn twisting machines
All the above mentioned spinning processes are conducted for making yarns from natural fibers. The synthetic yarns are formed through polymer processing
. For example, acrylic yarn is made from acrylic polymers
. The methods adopted for making these synthetic yarns include wet spinning, dry spinning, melt spinning etc. However, these are the methods for making filament yarns. There are many other yarns that are made from combination of staple and filament fibers. They are known as integrated multicomponent yarns. Integrated composite spinning and coverspun are the two significant methods for making such yarns..
