This study investigates the effect of material composition on moisture management properties. Fiber type has significant influence on the moisture management properties of knitted fabrics. In this article, single jerseys knitted fabric samples with different yarn compositions were prepared. Liquid moisture transportation properties including wetting time, absorption rate, spreading speed, one-way transportation capability, and OMMC were evaluated by Moisture Management Tester (MMT) and vertical wicking was evaluated using thermography system and image analysis. Knitted sample having fine cotton yarns with coolmax and micro denier multifilament polypropylene showed best liquid transportation properties. There is a strong co-relation between OMMC and accumulative oneway transport index with vertical wicking of knitted samples.

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.
