This paper deals with the evaluation of the moisture management of woven polyester fabric in three basic weaves – plain, twill and satin. It details types of liquid management and evaluates fabric comfort in terms of liquid moisture transport, drying speed and the moisture management of resistivity. It discusses the relationship between moisture management and the drying time of textile structures. New equipment is defined for drying speed determination, and its schematic and principles are discussed in this paper. Because the methods have some limitations and matters of presumption, the necessary interpretation of results is also discussed.

W artykule dokonano oceny zarządzania wilgocią tkaniny poliestrowej o trzech podstawowych splotach – gładkim, diagonalnym i satynowym. W pracy omówiono rodzaje zarządzania płynami i ocenę komfortu tkaniny pod względem transportu wilgoci w cieczy, prędkości suszenia i zarządzania odpornością na wilgoć. Przeanalizowano związek między zarządzaniem wilgocią a czasem schnięcia struktur tekstylnych. Zdefiniowano nowy sprzęt służący do określania szybkości suszenia, przedstawiono jego schemat i szczegółowo omówiono zasadę działania.

Waterproof breathable laminated fabrics have the special property that permits water vapour to pass through but protects by preventing the entrance of liquid water. Different characteristic properties of the layered constructions of these fabrics have good influence on their hydrostatic resistance and mechanical performance. This research study presents an experiment to enhance the hydrostatic resistance and tensile strength of four different types of hydrophobic membrane laminated waterproof fabrics by considering their breathability as well. For this purpose, water repellent coating based on C6-fluorocarbon resin along with polysiloxane hydrophobic softening agent was applied on these four different types of laminated fabrics using pad-dry-cure method. The coated fabrics were characterised by performing different experiments to evaluate the effect of coating on their hydrostatic resistance and mechanical property as well as on water vapour permeability and air permeability. From the test results and analysis of variance (ANOVA), it was found that hydrostatic resistance and tensile strength of the laminated fabrics were enhanced after coating along with proper water repellent property, whereas there were no significant changes in their water vapour permeability and air permeability.

Breathable layered waterproof fabrics have good applications in the fields of sportswear, protective clothing and construction industries. The properties of these fabrics in allowing water vapour to pass through while preventing liquid water from entering have made them unique. The mechanical properties of these fabrics are also very important for the satisfaction of the wearers. The layered constructions of these fabrics with different characteristic properties contribute to the influence on their hydrostatic resistance, mechanical properties and water vapour permeability. This study presents an experiment on eight different types of hydrophobic and hydrophilic membrane laminated layered fabrics used as sportswear during hot or cold weather. The hydrostatic resistance, tensile strength, stiffness and water vapour permeability of these fabrics were evaluated by varying different fabric parameters in the experiment. It was found from the test results that the fabric density, thickness and weight as well as types of membranes and layers have a significant effect on those properties of the layered fabrics.

Oddychające warstwowe materiały wodoodporne mają szerokie zastosowanie w odzieży sportowej i ochronnej. Zdolność przepuszczania pary wodnej i dobre właściwości mechaniczne takich materiałów są korzystne pod kątem komfortu ich użytkowania. Zbadano osiem typów membran hydrofobowych i hydrofilowych, stosowanych do produkcji odzieży sportowej używanej w czasie upałów lub chłodów. Oceniono właściwości hydrostatyczne, wytrzymałość na rozciąganie, sztywność i przepuszczalność pary wodnej tychże materiałów. Na podstawie wyników badań stwierdzono, że gęstość, grubość i gramatura materiału, a także rodzaje membran i warstw mają znaczący wpływ na właściwości hydrostatyczne i mechaniczne oddychających warstwowych materiałów wodoodpornych.
