    1. 1. Spinning Presentation By:-Sukhvir Sabharwal (TITS -2007 Batch) Triburg /// 1sukhvir.sabharwal.tit07@gmail.com
    2. 2. Spinning • The formation of yarn from fibers by spinning becomes possible when they have surfaces of cohesiveness. Flexibility permits the fibers to be twisted around one another. 2sukhvir.sabharwal.tit07@gmail.com
    3. 3. Spinning Process Chart 3
    4. 4. Spinning Process • Ginning & Mixing •  Blowroom •  Carding •  Drafting •  Combing •  Ring/Roter Spinning •  Winding •  Spinning 4sukhvir.sabharwal.tit07@gmail.com
    5. 5. Ginnig & Mixxing • Ginning –The primary object of the Ginning is to separate the fibers from cotton seed. • Separated fibers are mixed and goes to blow room process. 5sukhvir.sabharwal.tit07@gmail.com
    6. 6. Blowroom • Basic operations in the blowroom: -Blow Room involves a set of machinery which opens and cleans the raw cotton opening -cleaning -mixing or blending -microdust removal -uniform feed to the carding machine -Recycling the waste 6sukhvir.sabharwal.tit07@gmail.co m
    7. 7. Carding • THE PURPOSE OF CARDING: Before the raw stock can be made into yarn, the remaining impurities must be removed, the fibers must be disentangled, and they must be straightened. This straightening process puts the fibers into a somewhat parallel lengthwise alignment.The initial process of arranging the fibers in parallel fashion is known as carding.The result from the carding machine is called as card sliver. 7sukhvir.sabharwal.tit07@gmail.com
    8. 8. Combing • The process of straightening and parallelisings of fibers and the removal of short fibers and impurities by using a comb on combs assisted by brushes and rollers is called combing. The combing process • 8sukhvir.sabharwal.tit07@gmail.co m
    9. 9. Draw frame • Drawframe is a very critical machine in the spinning process. It's influence on quality, especially on evenness is very big.If drawframe is not set properly, it will also result in drop in yarn strength and yarn elongation at break.The faults in the sliver that come out of drawframe can not be corrected . It will pass into the yarn 9 sukhvir.sabharwal.tit07@gmail.com
    10. 10. Roving Frame/Speed Frame • The bobbins are placed on the roving frame, where further drawing out and twisting take place until the cotton stock is about the diameter of a pencil lead. There are two stages in roving: intermediate and fine. The operations are identical. Roving is the final product of several drawing-out operations. It is the preparatory stage for the final insertion of twist. 10sukhvir.sabharwal.tit07@gmail.co m
    11. 11. Rotor/Open end spinning • Coarser yarn are made on open end from 4s to 30s. • Rotor yarn is mainly used in Denim, Sheeting, Home furnishing and Terry towels. 11 sukhvir.sabharwal.tit07@gmail.com
    12. 12. Ring Spinning • Spinning process is done by the machine called Ring frame. Ring frame converts the bobbin into a yarn. The bobbin taken from the previous process Fly frame is mounted on Ring frame either automatically or manually. The Ring frame stretches the material using a drafting 2s to 140s • Ring yarn is finer then open end • It has more hairiness as compare to open end 12sukhvir.sabharwal.tit07@gmail.co m
    13. 13. Types of spinning • The roving, on bobbins, is placed in the spinning frame, where it passes through several sets of rollers running at successively higher rates of speed and is finally drawn out to yarn of the size desired. Spinning machines are of • two types: ring frame and mule frame. The ring frame is faster process, but produces relatively coarse yarn. For very fine yarns the mule frames are used. • As the fibers pass through these processes, they are successfully formed into lap, sliver, roving and finally yarn. Fibers may be blended during the spinning process. The blending procedure varies with its compatibility with the particular spinning techniques listed below: •  Open-end spinning •  Friction spinning •  Self-Twist spinning •  Electrostatic spinning •  Vortex spinning •  Air-jet spinning •  Twistless spinning •  Wet spinning •  Dry spinning •  Melt spinning •  Bicomponent spinning •  Bicostituent spinning •  Film splitting •  Integrated Composite spinning •  Coverspun •  Selfil •  Aerodynamic spinning 13 sukhvir.sabharwal.tit07@gmail.com
    14. 14. TYPES OF YARNS • There are various types of yarns, having its own characteristics. These characteristics vary according to the construction and treatment given in the manufacture of yarn. The different types of yarns are listed below: •  Ply yarns •  Cabled yarns •  Doubled yarns •  Novelty yarns •  Slub yarns •  Flake yarns •  Spiral yarns •  Ratine yarns •  Boucle, loop or curl yarns •  Nub, Knop, Knot or Spot yarns •  Chenille yarns 14sukhvir.sabharwal.tit07@gmail.co m
