Abstract: An optical filtering technique is used to improve the on-line quality characteristic of textile yarn. This enables measurements to be made of the size of the main body of the yarn and the variation in hairiness along the length of the yarn. This technique has been found to be entirely satisfactory in practice because the two parameters are parallel- recorded. A prototype system is described; it offers a wide range of benefits such as on-line recording results, easy measurements, very high operating velocity and compactness. Examples of results are presented.
