Introduction to Spinning:

The process of converting fiber into yarn is called as Spinning.

Flow Chart of Spinning:

Objectives:

Blowroom:

Opening: Open the material into very fine tufts
Cleaning: Eliminate most of the impurities.
Mixing and Blending: Provide a good blend of two different fibers.
Lap or Flocks formation: To form sheet of fiber with uniform weight and width called lap or transfer the fibers in open form to card through chute feed.

Input- Fibers Output- Lap/Fibers in chute feed system

Carding:

Opening into individual fibers: To open the tuft of fibers into individual fibers.
Elimination of Impurities: To remove remaining trash particles from the material.
Elimination of Dust
Disentangling Neps: To remove neps from the fibers.
Sliver Formation: Formation of Uniform strand i.e Sliver.

Input- Lap/Fibers from Chute Feed Output- Carded Sliver

Drawframe:

Equalizing: To improve the evenness over short, medium and long term in the sliver.
Parallelizing: To arrange the fibers parallelly in the sliver strand by drafting.
Blending: Blending of sliver of two different materials can be achieved at Drawframe.
Dust Removal

Input- Carded Sliver Output- Drawn Sliver

Speed Frame:

Attenuation of Sliver: Drafting of the sliver strand.
Insert twist & Roving Formation: To insert small amount of twist so to hold the strand of fibers together.
Winding on bobbin: To wind the twisted roving strand into a bobbin.

Input- Drawn Sliver Output- Roving

Ring Frame:

Drafting: To draw the roving to the specified degree of fineness.
Twisting: To impart sufficient twist to the emerging strand of fibres to form a continuous length of yarn
Winding: To finish up the small stuff into convenient package called as bobbin.

Input- Roving Output- Yarn

Comber:

Note: Input and output except comber are for carded yarn.
