Application of textiles as technical products demands they meet new requirement. Thus an important property of some textiles is their fatigue strength. Functional loads courses of some products can be used just sporadically as a program of fatigue examination. At the beginning they normally should be schematized or filtered to obtain useful program of loads. There are described typical ways of functional course processing, used so far in fatigue strength of construction parts, in the paper. It was found that the traditional analysis of complex functional load courses is labor-consuming. For this reason, nowadays specific software is used for such analysis.

In the paper the problem of assessment of textiles fatigue property is taken up. The wide range of textiles application, including technical textiles, requires knowledge of their behaviour under varied kind of loads. Materials fatigue phenomenon of machine and construction elements as well as methodology and test equipment have the mirror in professional literature. In the case of fibres and textiles the main stream of interest focuses on strength characteristics determined under static or quasi-static conditions. This approach in many cases is insufficient to proper estimate of their utility in real using conditions. The fatigue test issue of textiles isn’t New but as soon as it have not taken rightful place in complex textiles assessment.

Physiological aspects of water vapour transport through clothing textiles were presented. Conditions of thermophysiological comfort and thermoregulatory meaning of perspiration are depicted. One was concluded that, for choosing right clothing materials, assessment of their barrier properties acccordant with users' feeling is important.

There are many theories concerning designing of the woven clothes made of the multifilament threads. This relatively new group of technical clothes that are made of stripes lacks the theoretical background. This paper discusses and analyses the geometrical possibilities of the change in porosity and the tensile strength of clothes that are made of stripes. The starting point for the analysis was the theory of geometrical similarity of the woven cloths. Based on this theory, it is demonstrated here that the possibilities of the change In porosity and the tensile strength of clothes that are made of stripes are less for clothes made of multifilament threads.

The humidification phenomenon of the space closed by the body and clothing fabric was investigated using physical simulation of mass and heat transfer on a Hy-tester computer system. Measurements were performed at fixed conditions, including water supply rate, temperature and pressure gradients. The humidity of air in the closed space above the specimen was maintained at a fixed level by using an adjustment drying system with a pump. Changes of air properties, such as relative humidity and temperature under the specimen versus time, were measured and recorded. On the basis of the model of water vapour concentration in a cell closed by the specimen and the model of drying pump voltage, a kinetic balance of water vapour mass was determined. The kinetic curves of humidification flux obtained, sorption flow and transferred flow are characteristic for tested materials and they display the moisturising and drying process of a clothing microclimate.

Za pomocą komputerowego systemu Hy-tester, stosując metodę fizycznej symulacji procesu przenoszenia masy i ciepła, badano zjawisko nawilżania powietrza w przestrzeni zamkniętej tkaniną odzieżową. Pomiarów dokonywano przy stałej szybkości dozowania wody oraz pod działaniem gradientu temperatury i ciśnienia powietrza. Dzięki zastosowaniu systemu osuszania z pompą perystaltyczną, wilgotność powietrza w przestrzeni ponad badanym materiałem była utrzymywana na określonym poziomie. Mierzono i rejestrowano czasowe zmiany wilgotności względnej i temperatury powietrza pod próbką. Na podstawie modelu uwzględniającego stężenia pary wodnej w komorze pomiarowej zamkniętej badaną próbką oraz modelu zasilania pompy osuszającej wyznaczono kinetyczny bilans pary wodnej. Otrzymane w ten sposób kinetyczne krzywe strumienia nawilżającego, strumienia sorbowanego oraz strumienia przenoszonego są charakterystyczne dla badanych materiałów i obrazują zjawiska nawilżania oraz osuszania mikroklimatu odzieżowego.
