Abstract
The invention provides a method of testing yarn comprising periodically feeding a length of yarn by means of a fluid stream along a pathway so that it extends between a pair of spaced clamps, clamping the length of yarn towards the ends thereof by means of the clamps and causing one or both clamps to move relative to the other progressively to tension the yarn until breakage. Tension and elongation of the yarn is measured.
