| Description
| - Yarn diameter is an important determinant of many fabric parameters and properties e.g. cover factor, porosity, thickness, air permeability, fabric appearance,.. etc. There are many methods based on different types of sensors used for characterization of yarn unevenness. These instruments differ in the principle of measuring and the logic of evaluation of yarn irregularity. It is essential to investigate more deeply which of these methods is more reliable and to establish a relationship between the results obtained from different techniques. Uster tester 4 equipped with the optical sensor OM, Lawson Hemphill YAS system, Quick Quality management QQM3, were used in this study. Optical microscope has been also applied using cross sectional method and longitudinal method for evaluation of yarn diameter. The present investigation focuses on analysis of the data obtained from these commercial instruments as a stochastic process. It was found that a bimodal distribution can be applied to characterize the yarn diameter. The D-yarn program developed also supports this fact and deliveries much information about the characteristics of yarn diameter. Beside many other techniques, the autocorrelation function, spectrum analysis and fractal dimension was used.
