Abstract: This study investigates the drying kinetics of electrospun nanofibrous mats prepared from 9 wt.% PVA solutions modified with a micro-emulsion containing aminosiloxane and Aloe vera (ASAV). The additive was incorporated into the PVA solution at concentrations of 0.4-1.0 wt.%, and the obtained nanomats were subjected to thermal treatment at 70-110°C using a laboratory moisture analyzer. Residual moisture removal was monitored for 60 minutes and evaluated using two-factor ANOVA with replication. The results reveal statistically significant main effects of temperature and ASAV concentration (p < 0.001), while no significant interaction between the factors was detected. Increasing temperature significantly accelerates moisture removal, whereas ASAV concentration introduces secondary but systematic variations in drying behavior. These findings provide quantitative guidance for optimizing thermal post-treatment conditions of Aloe-modified PVA nanofibrous systems intended for electrospinning and sanitary applications.
