The use of super absorbent polymers (SAP) for moisture absorption and comfort is still unexplored. The aim of this work was to observe the application of super absorbent fibres in car seats for comfort purposes. In this research the efficiency of different SAP fibrous webs were determined under different moisture percentages to examine the sorption and desorption efficiency. A SAP fibrous web with low thickness and high moisture absorption were tested with a multilayer sandwich structure of a car seat cover to determine moisture absorption through the cover material. The standard Cup method was used to determine the moisture permeability of different car seat covers with a superabsorbent layer closed with impermeable polyurethane foam. It was observed that the SAP fibrous layers are very effective in absorbing and desorbing water vapour under extremely high and low moisture percentages. In extreme humid conditions (95%RH), 20g of the SAP layer absorbs nearly 70% of its weight in water vapour, reaching the maximum absorption capacity in 6 hours.

W fotelach samochodowych, w celu podniesienia ich właściwości użytkowych, zastosowano włókna superabsorbujące . Badano efektywność różnych tkanin poprzez określenie sorpcji i desorpcji w różnej wilgotności. W celu określenia absorpcji wilgoci przez materiał pokrywający fotele samochodowe badano superabsorbujące materiały włókniste o małej grubości i wysokiej absorpcji wilgoci. Określono przepuszczalności pary wodnej dla różnych pokryć foteli samochodowych. Zaobserwowano, że materiały superabsorbujące są bardzo efektywne w absorpcji i desorpcji pary wodnej w ekstremalnie wysokiej i niskiej wilgotności. W warunkach ekstremalnych, przy wilgotności (95% RH) 20 g warstwy SAP pochłania prawie 70% ciężaru pary wodnej i osiąga maksymalną zdolność absorpcyjną w ciągu 6 godzin.

Decision making process in current tactical C2 systems is base on planning process of commanders and their staff. Improving tactical decision making by interfacing war game simulations with tactical C2 systems is achievable. Commander can review the results of the simulation and subsequently modify the tactical plan. Previously, the use of "training" simulations was not a viable solution to real world decision making due to the lengthy time required to input all of the combat entities, the unit organizations and personnel dispositions, the equipment configurations, status of the units and equipment, and the distribution of the available supplies. Modern C2 systems have all of this information stored in the common system databases, and this information can be used to instantiate and populate the simulation through an electronic adaptation of the data structures to match the requirements of the constructive simulation. This paper will provide description of system approach of interfacing simulation and C2 system to improve decision-making.
