Introduction to Spinning:

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

Flow Chart of Spinning:

  • 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


  • 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


  • 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


  • Removal of Short Fibers: To remove short fibers of pre-determined length.
  • Impurities removal from lap: Remove impurities from comber lap.
  • Sliver formation: To produce a consistent sliver of required per unit length.

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

Alternative Spinning Processes (Other than Ring Spinning):

  • Rotor Spinning
  • Air Vortex Spinning
  • Electrostatic Spinning
  • Friction Spinning
  • Wrap Spinning
  • Bobtex Process
  • Adhesive Process
  • False Twist process
