Difference Between Precision Winding and Non Precision Winding
Precision Winding:
In case of precision winding process, continuous coils of yarn on winding package are laid parallel or near parallel to each other. As a result, very dense package is formed here. The packages which are produced by precision winding process contain maximum amount of yarn in a given volume.

| Precision and non precision winding difference |
Non Precision Winding:
In case of non-precision winding process, winding package consists of a single yarn. Here, wounded single yarn laid in the winding package at substantial helix angle so that the wound yarn cross one another and provide stability. In case of non-precision winding process, less dense package is formed.
