5 Poor yarn quality: Inconsistent twist or diameter.

6 Handling/Storage: Mishandling or poor stacking.

Rectification
1 Optimize tension: Adjust winding tension properly.
2 Ensure Package Shape: Avoid overfilling and
maintain uniformity.

3 Use anti-slough devices: Caps or rings to secure
layers.
4 Adjust machine settings: Tune traverse speed and
angles.

Effect
a Yarn damage: Cuts or abrasions on the yarn surface.

b Reduced strength: Compromised yarn integrity leads
to breaks during downstream processes.
c Quality issues: Causes weak points or defects in
finished fabrics.
