A method of monitoring yarn quality in a yarn texturing process comprises measuring the velocity of the travelling yarn at two locations and comparing the measured velocities. At a first location the yarn tension is sufficient to draw out the crimp and at a second location the tension is lower such that the crimp is developed. Apparatus for performing this method comprises a measuring device (28) ...
