Effect of Aggressive Components of the Marine Environment the Protective Properties of the Textile Materials

Abstract

The article provides the details on the influence of marine environment on textile materials. It justifies the aggressive components of marine environment in contact with clothing surface: sea salt and oil. Sea salt is an integral part of sea water and accumulates in the structure of clothing. Oil becomes a part of sea water in contingency situations at offshore oil and oil products production and transportation facilities. This causes a variation of the properties of textile materials that depend on the concentration of aggressive components in the structure of textile materials. Active concentration of aggressive components in the textile is defined based on its liquid absorption capacity. The article establishes the peculiarities of volume variation for different textile fibers interfacing with liquids. It identifies the structure of sea salt and chemical composition of oil that cause a variation of the properties of textile in contact with them. It was established that the presence of sea salt in humid environment contacting with the surface of special cotton based fabric causes reduction of capillarity in all material samples. It was established that the packages of materials based on fabrics with mixed fibers have crude oil permeation less than cotton surfaces of clothing. Meanwhile, use of thermal insulation, like Hollofiber together with such materials, reduces the level of clothing saturation with subject liquids. The article presents experimentally obtained data on sea water and oil permeation into special clothing materials.
