Difference between Precision Winding and Non Precision Winding

The difference between Precision winding and Non Precision Winding are given below,
Precision Winding
Non Precision Winding
1. Number of coils remains constant from the first layer up to the full diameter of package.
1. Number of coils per traverse of yarn guide decrease with increase in package diameter.
2. No air gaps.
2. Air gaps are found here.
3. Winding angle is 90º or near 90º.
3. Winding angle is less than 80º.
4. Bobbin can be wound by one or more yarn.
4. Bobbin can be wound by only one yarn.
5. Less stable package.
5. More stable package.
6. Flanged bobbin is needed.
6. Flanged bobbin is not needed.
7. Yarn tension is relatively more at the time of winding.
7. Yarn tension is relatively less at the time of winding.
8. Yarn package density is more.
8. Yarn density is less in the package.
9. Yarn coil is arranged in the parallel or near parallel.
9. Yarn coil is arranged in traversal.
10. Yarn withdrawal from the package takes more time and it is relatively difficult.
10. Yarn withdrawal from the package takes less time and it is comparatively difficult.
