Synthetic leather via natural is one of the most common synthetic leather with higher quality. Real leather goods are preferred by many customers because of their excellent properties, such as good water vapor permeability, and wearing comfort. Therefore, the development of synthetic leather via natural with excellent performance as a supplement of real leather has gained increasing attention and has become a widely interesting research topic. Synthetic leather via natural can be described as faux leather which has been emerged in recent years and became the most ideal substitute for real leather. Continuous development in this research area led to an expansion of faux leather applications.
In this study three different types of synthetic leather via natural were examined before and after sewing with superimposed seam. Tests were applied to determine the physical properties like thickness and stiffness, the functional properties like tensile strength, elongation, crease recovery, air permeability, vapor permeability, abrasion resistance, and colorfastness to light in addition to the seam properties like seam thickness, seam stiffness, seam tensile strength, seam pucker and seam appearance. All tests were done according to standards and took place into conditioned atmosphere of 21ºC and 65% RH. Comparisons have been made among them; this was done with reference to durability, efficiency and appearance
