This study investigates influences of some washings, special treatment processes and bleaching on some physical, mechanical properties, and hand evaluations of jeans produced from two types of denim fabrics. Processes were applied systematically on sewn jeans products to see effects of individual applications clearly. According to the results, fabric type and all of the finishing processes applied to obtain worn appearance and aged look have significant influences on mechanical properties of denim fabrics. Stone washing and its combination with bleaching were determined as the most aggressive applications for denim fabrics. Although significant decrease was observed on the fabric in terms of tear strength and breaking elongation, enzyme washing can be recommended as an environmentally friendly and less damaging option.
