Design of rain protective materials with satisfactory comfort-related properties

Resistance to water penetration is the most important quality of materials that should provide adequate rain protection. At the same time, those materials need to be breathable in order to evacuate the perspiration away from the skin and from the garments. Within the meaning of all above mentioned, this paper focuses at the design of two-layered materials and investigation of their water vapour resistances.The results indicated that the samples produced from polyurethane that comes from the copolimer of polyester/polyeter have at least 6 times lower water vapour resistance than those produced from the base of hydrophilic polyester. Because of higher differences in obtained values, this is an important fact that should be taken into account when designing a product that will assure the optimal wear comfort.
