Yarn & Fabric Formation by Sukhvir Sabharwal

  1. 1. Processing of Cotton YARN & FABRIC FORMATION By:-Sukhvir Sabharwal B-Tech 2007 Batch TITS Bhiwani (INDIA)

  4. 4. Ginning• Ginning is the separation of seed from seed cotton• Recovery of clean lint. The process requires a dryer, a gin saw or some other type of separation devices.• The clean lint is then compacted and tied with a bale wrap.• It is finally weighed and stored.
  5. 5. Opening and Cleaning of Raw Cotton • The object of this process is to blend cotton so as to obtain uniform raw material, remove leaf dirt and fresh, open up the fibres after they have been compressed in the bale • To deliver a clean uniform product in a suitable form to the nextstage.
  6. 6. Blow room• The blow room machinery performs function of opening hard pressed bales of cotton and cleaning the cotton of impurities
  7. 7. Carding• In carding, the lap is attenuated into a sliver (about 100 draft)• The fibres made parallel for the next stage.
  8. 8. Drawing• Drawing evens the sliver.• It attenuate the sliver to desired count• Doubling reduces mass CV
  9. 9. Roving• Roving further attenuates the sliver to above 7 draft.• It makes the sliver useful to make yarn
  10. 10. Spinning• There are two main types of spinning: ring spinning and open-end or break spinning.• In ring spinning the roving is further attenuated by roller drafting to the fineness of the yarn required, usually a draft of about 20• and at the sametime twist is applied to give the yarn the necessary strength.• Full bobbins may be manually or automatically doffed.
  11. 11. Cone winding• Cone winding facilitates subsequent processing by rewinding yarn onto a large package• and removing faults.

  15. 15. TYPE OF CONE
  16. 16. Warping• To make bigger package to supply warp yarn• Yarn with uniform tension
  17. 17. Sizing• The purpose of sizing to increase weaving resistance• Resistance against abrasion
  18. 18. Drawing in• The drawing-in of the sized warp threads through the heddles, reeds and drop-wires of the loom• May be done either manually by a pair of workers
  19. 19. Weaving• Interlace between two sets of yarn• Weaving is the crossing of yarns at right angles or strips of other materials to produce a flat, more or less compact surface.

  22. 22. Woven structures Plain weave
  23. 23. Woven structuresTwill weave Twill weave, the secondbasic weave, is characterized by diagonal lines running at angles varying between 15° and 75°. A twill weave is denoted by using numbers above and bellow a line (such as 2/1 twill which may be interpreted as two up and one down in the shedding sequence).
  24. 24. Woven structureSatin and Sateen weave Sateen weave is the third basic weave, in which the interlacing points are arranged in a similar way to twill weaves but without showing the twill line. The satin weave is warp face weave and the sateen is a filling face weave. Fig. Shows 5 ends (Harness) satin. In this case, the repeat is on 5 ends x 5 picks.
