Types of Yarn Winding

Types of Winding:

Precision winding:
By precision winding successive coils of yarn are laid close together in a parallel or near-parallel manner. Through this process, it is possible to produce a very dense package with the maximum amount of yarn stored in a given volume.


  • The package is wound with a reciprocating traverse
  • Patterning and rubbing cause damage of packages
  • The package contains more yarn
  • The package is less stable
  • The package is hard and compact
  • The package is dense
  • The rate of unwinding of the package is low and the process of unwinding is hard
  • The unwound coil is arranged in a parallel or near-parallel manner

Non-precision winding:
By this type of winding the package is formed by a single thread which is laid on the package at an appreciable helix angle so that the layers cross one another and give stability to the package. The packages formed by this type of winding are less dense but more stable.


  • Only one coil is used to make this package
  • The cross-winding technique is used
  • The packaging density is low
  • The minimum number of yarns is wound
  • The package formed is soft and less compact
  • The stability is high
  • Flanges are not required
  • The rate of unwinding is high and the process is easy
  • The packages formed have low density

Difference between Precision and Non-Precision Winding:

1. No. of coils remain constant from the first layer up to the full diameter of package.1. No. of coils per traverse of yarn guide decrease with increase in package diameter.
2. No air gaps.2. Air gaps is found here.
3. Winding angle is 90°or near 90°3. Winding angle is less than 80°
4. Bobbin can be wound by 1 or more yarn.4. Bobbin can be wound by only one yarn.
5. Less stable package.5. More stable package.
6. The yarn package is hard and more compact.6. The yarn package is soft and less compact.
7. Flanged bobbin is needed.7. Flanged bobbin is not needed.
8. Yarn tension is relatively more at the time of winding.8. Yarn tension is relatively less at the time of winding.
9. Process is less hairy.9. Process is more hairy.
10. Yarn package density is more.10. Yarn density is less in the package.
11. Difficult to dye, only surface yarn is dyed properly11. Easy to dye.
12. Yarn coil is arranged in the parallel or near parallel.12. Yarn coil is arranged in traversal.
13. One or more yarn can be wound in package here.13. Single yarn is wound here.
14. Yarn withdrawal from the package takes more time and it is relatively difficult.14. Yarn withdrawal from the package takes less time and it is comparatively easier.
