English term or phrase: rise of the fibre helix
The rotation of the fibre helix, q , and the rise of the fibre helix, H can be expressed as:
q = b2 - b1 , H = z(b2) - z(b1) .

English translation:the slope of the helix
Explanation:
If you imagine a helix as a wound spring standing upright (long axis vertical) and viewed from the side, the rise or slope of the helix is the 'steepness' of the individual turns of the helix.

As I understand your text, it specifies that 'pure rotation' means that a given point on a helix of the yarn before rotation ends up at a different point along the mathematical line of the helix after rotation, but the helix slope does not change. This means that the helix has not been stretched or compressed, as stretching or compression would change the slope.

'rise' means the change in height (assuming the helix is oriented vertically), or more generally the rate of change in height as a point moves along the path of the helix. It is essentially synonymous with 'slope'.
