False twisting:
- a twisting operation applied at an intermediate position on a yarn so that no net twist can be inserted, as distinct from twisting at the end of a yarn where real twist is inserted.

Festooning:
- festooning, or plaiting, is used in the case of materials which can not be wound on to a roller prior to further processing for reasons of practicalities or economics. For instance, if the fabric is thick but narrow there is a practical limit on the amoun
