The process of making a yarn by some separate process like carding,
drawing, drafting, roving, spinning from a textile fiber to a specific yarn is called the yarn manufacturing. It can be differ by process to process. As we know that there are two types of fiber. One is man made and other is natural fiber. So while processing man made fiber, the process could differ.
For staple fiber process we basically use some special machine like, ring spinning, open end / rotor Spinning, friction spinning, self twist spinning, electrostatic spinning, vortex spinning, air-jet spinning, twist-less spinning.
For filament fiber process to yarn we have to use other methods. There are some spinning process for the filament yarn. Now a days these are widely used. These are wet spinning, dry spinning melt spinning, bi-component spinning, film splitting.
There is another yarn manufacturing method. It is called the integrated multi component yarns. It is produced by mixing staple yarn and filament yarn. That is why it is called integrated multi component yarn. It is done with integrated composite spinning, cover spun, selfil yarn spinning, aero-dynamic spinning.
