  • 4.  The process of making the yarn from a textile fiber is called Spinning.  Yarn is defined as a linear assemblage of the fibers twisted together.
  • 5. B. Yarns are classed based on fiber length and method of processing
  • 6. 1) Blow room a) Mixing bale opener b) Condenser & cages c) Hopper feeder d) Breaker scutcher e) finisher scutcher f) Lap forming unit
  • 7. 2) Carding 3) Draw frame 4) Speed frame 5) Ring frame
  • 8. Make – lakshmi reater Model- lb 3/2
  • 9. 1) Reduction of bigger tufts of material into small size. 2) Removal of trash.
  • 10.  BALE OPENING or BREAKING:  The cotton tufts are opened in this process.  As the cotton arrives in an extremely compressed condition the first operation is to loosen the matted fibers  The cotton fiber is loosen by means of rotating spiked rollers of the bale opener.
  • 11.  This is a process of mixing the same/different category of fibers to get desired properties and cost effectiveness.  Mixing is done after the study of the essential properties of fiber like staple length,Tensile strength, fineness, uniformity etc.
  • 12. 1) Condensation of loose fibre into sheet form. 2) Removal dust trough suction.
  • 13. 1) Reduction of tuft size. 2) Opening cleaning & removal of trash. 3) Condensation of fibre.
  • 14. 1) Maintaining uniform eveness . 2) Feeding to finisher scutcher.
  • 15. 1) Extraction of trash by opening with two bladed beater. 2) Cleaning of the open material with dust removal.
  • 16. 1) Further cleaning by opening with krishner beater. 2) Maintain uniform evenness. 3) Removal of dust.
  • 17. 1)Convert shed of fibre into lap.
  • 18. 1) Indiviualization of fibre. 2) Removal of trash & dust. 3) Removal of short fibre & nep. 4) Conversion of lap into sliver.
  • 19.  Carding is the heart of spinning in this process the minute impurities like small seed particles,immature fibers etc. are removed.  The straightening and aligning of fibers are done in this process.  In carding the Blow room lap is attenuated to the card sliver.
  • 20. 1) Parallelisation of fibre. 2) Reduction in trash. 3) Improving in uniform way by doubling.
  • 21.  Through drafting fibbers get paralleled  Up to Eight Carded Slivers are fed into the Draw-Frame and they are stretched/Straightened and made into a single sliver.  Also fiber blending can be done at this stage.
  • 22. 1) Reduction of no. of fibre into sliver. 2) Parallelisation of fibre & convert in roving.
  • 23.  Further drafting is done here to get the fibers more aligned/paralleled.  The Sliver from Draw-Frame is thicker and will be difficult to be fed into the Ring-frame as is, hence here the Slivers are stretched and were made thinner by Drafting and mild twisting (so as to strengthen the Roving).  The End-Product from the Simplex is called as Roving.
  • 24. 1) Conversion roving into yarn. 2) Improving the strength by twisting. 3) Winding into suitable package.
  • 25.  The roving is fed into the Ring-frame and is made into yarn by further Drafting & Twisting.  Basic Functions of Ring Frame  to draft the roving until the required fineness is achieved
  • 26.  to impart strength to the fiber, by inserting twist.  Depending upon the yarn count required , the drafting and twisting can be adjusted.
