AbstractMoisture-proof polymer-coated textile materials are widely used for the manufacture of special clothing for workers in the oil, gas, chemical and other industries. During operation, such materials are subjected to the complex effects of mechanical loads (multi-cycle bending, stretching, abrasion) and environmental factors (temperature fluctuations, precipitation, ultraviolet radiation). The combined effect of these factors leads to a gradual decrease in protective properties, primarily a decrease in the level of water resistance. In this regard, an urgent task is to assess the combined effect of mechanical wear and environmental factors on the level of water resistance. The aim of the work is to determine the effect of air temperature and multi-cycle bending on the level of water resistance of coated textiles to predict the wear life of the product. Two types of water-resistant textiles with a microporous polyurethane coating and a membrane layer, manufactured by Mogotex (Republic of Belarus), were selected as the objects of study. To determine the change in the water resistance of the water-resistant coated textiles after exposure to high-cycle bending at specified temperature and humidity parameters, a method for studying the performance properties of water-resistant materials under various temperature and humidity conditions was used. To identify the combined effect of air temperature from +5 to +15 °C and the number of bending cycles in the range from 150 to 300 kilocycles on the water resistance level of the studied coated textile materials, a complete factorial experiment was conducted and exponential multiplicative models were developed. The resulting models and patterns can be used for scientifically-based forecasting of the service life of workwear depending on the climatic conditions of the region and the intensity of mechanical loads. |
