  1. 1. Weaving Presentation By:-Sukhvir Sabharwal Triburg /// 1sukhvir.sabharwal.tit07@gmail.com
  2. 2. 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. 2 sukhvir.sabharwal.tit07@gmail.com
  3. 3. Weaving Preparatory Process • Before weaving, the weaver beam needs some few operations before placing the beam on loom • Warping • Sizing • Drawing 3sukhvir.sabharwal.tit07@gmail.com
  4. 4. Warping • To make bigger package to supply warp yarn • Yarn with uniform tension 4sukhvir.sabharwal.tit07@gmail.com
  5. 5. Sizing • The purpose of sizing to increase weaving resistance • Resistance against abrasion 5 sukhvir.sabharwal.tit07@gmail.com
  6. 6. Drawing in • The drawing-in of the sized warp threads through the heald eyes, reeds and drop-wires of the loom • May be done either manually by a pair of workers 6 sukhvir.sabharwal.tit07@gmail.com
  7. 7. Types of Looms • Hand loom • Power Loom • Jacquard Looom • Air Jet Loom • Water Jet Loom • Rapier Loom • Sulzer Loom • Projectile 7sukhvir.sabharwal.tit07@gmail.com
  8. 8. Loom Chart 8 sukhvir.sabharwal.tit07@gmail.com
  9. 9. • Handloom : weaver could sit at the centre of the loom and merely pull the handle to make the shuttle move from one end of the fabric to insert a weft thread. 9sukhvir.sabharwal.tit07@gmail.com
  10. 10. • Power loom : Earlier version of power loom were run by two man. Soon power looms were driven by steam and most of the wooden parts were replaced with iron. The average speed of the power loom had increased from 60 to 140 picks per minute with the rise on productivity. • Productivity of this m/c is very low upto 20 to 24 meter per day • The weft insertion is done thru shuttle which has a capecity of 10 meter, iot means after every 10 meter there will be a knot 10sukhvir.sabharwal.tit07@gmail.com
  11. 11. • Automatic Loom/Shuttleless loom : Traditional Power looms were stopped every few minutes in order to replace the empty weft pirns in the shuttle and this limited the number of looms, a weaver could operate to about four. Later an automatic weft transfer system which replaced the weft pirn in the shuttle without slowing or stopping the loom. The average speed of the Automatic loom is 100 to 200 meter per day. • 11sukhvir.sabharwal.tit07@gmail.com
  12. 12. • Shuttleless Loom : The dynamic problems created by the picking and checking mechanism and the inherent process of pirn winding for shuttle looms had encouraged the loom makers to develop alternative means of weft insertion in which heavy shuttle is not projected forwards and backwards across the width of the loom. It is customary to refer these looms as shuttleless looms. 12sukhvir.sabharwal.tit07@gmail.com
  13. 13. • MAJOR FAULTS • Starting Mark • Double Pick • Brocken Pick • Thick Place • Miss Pick • CUTTABLE FAULTS • Crack • Tear • Fabric Cut • Multiple Breakage • Float • CONTINUOUS FAULTS • Wrong Pattern • Missing End • Stitches • Reed Cut • Temple Cut • MENDABLES • Loom Fly • Bent Pick • Hanging Thread • Snarling • Loops 13sukhvir.sabharwal.tit07@gmail.com

  17. 17. Woven structures Plain weave 17sukhvir.sabharwal.tit07@gmail.com
  18. 18. Woven structures Twill 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). 18sukhvir.sabharwal.tit07@gmail.com
  19. 19. Woven structure Satin 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. 19sukhvir.sabharwal.tit07@gmail.com
