Measurement Of Lateral Yarn Density Distribution
Apparatus for measuring the lateral yarn density distribution of a yarn uses selected radiation in the X-ray spectrum wavelength. Radiation absorption is determined in a number of narrow planes across the yarn and in two or more rotational orientations. The measuring takes place without any damage to or physical interference with the yarn.
