variance analysis of hydrophylic behaviour of vlieseline performed on the basis of parameters of its exposure to the glow discharge

The subject matter of the article represents summarized findings of the variance analysis of the fractional factorial experiment (the Latin Matrix). The items analyzed collectively by the coauthors include the discharge current, the pressure of the orifice gas, or the air, and the period of exposure to the direct current of the glow discharge. The properties analyzed by the coauthors include the water absorption capacity, the wettability, and the capillary rise of the repair vlieseline. The discharge current range was 20-100 mA, the pressure range was 50-200 Pa and the treatment time range was 15-120. The experiment was conducted according to the Latin matrix method, and the analysis of variance (ANOVA) was used to check the influence of the discharge current, pressure and the treatment time onto the hydrophilic properties of the material. The coauthors have demonstrated that the discharge parameters are an insignificant factor in comparison to the exposure period.
