Abstract [eng] |
In this study, different samples of commercially available breathable polyurethane (PU)-coated fabrics were experimentally tested applying the crumple/flex method. The flexing fatigue resistance test involves the nucleation of damage that is responsible for coated fabric failure. Therefore, views of coating were made by means of scanning electron microscopy (SEM to look for signs of coating cracking or other damage. In addition, we tested two of the most important end use characteristics, i.e. windproofness and waterproofness, of breathable-coated textile materials before and after the flexing fatigue resistance test. To study the trends in relationships between the number of flexing cycles and the resistance to water penetration of the materials tested, a regression analysis was made. The dependencies of all the fabrics tested in the warp and weft directions can be described by exponential equations with the coefficient of determination R-2 within the range of 0.72 and 0.96. Residual values of the resistance to water penetration were also computed with respect to their initial values. On the grounds of the dependencies proposed, the suitability of the fabrics is discussed. |
