This paper contains a comparative analyse of the statistical spreading parameters for some quality characteristics of thin flax yarns, 50 tex (Nm 20), 41.7 tex (Nm 24) and 38, 5 tex (Nm 26) from hackling flax, produced by wet spinning from bleached roving. This analyse make it possible to take decisions in a very short time about the behaviour of these yarns in the following stages of processing and in use. The statistical values used for characterisation of qualitative parameters distributions of yarns investigated are the coefficient of asymmetry, the coefficient of vaulting and the coefficient of excess. These coefficients make it possible to analyse in detail the distribution in comparison with the normal distribution.
The statistical analysis of the distribution flax yarns characteristics was made by the mathematical programme software proposed by authors. This project began with fibres characterization because yarn strength and component fibres properties have a strong correlation.
