Özet
<p>Dye transfer from shoe lining leathers to socks or human skin is a prevalent issue in the footwear</p><p>industry, often resulting in consumer dissatisfaction. One of the key factors in preventing this</p><p>problem is the rubbing fastness of dyed leathers, which is significantly influenced by the dye</p><p>type and dyeing process used. This study investigates the impact of various dye types and</p><p>dyeing methods on the rub resistance properties of shoe lining leathers. Specifically, acid dyes,</p><p>1:2 metal complex dyes, and reactive dyes were applied to six chrome-tanned crust leathers</p><p>under controlled laboratory conditions. After dyeing, the rub fastness properties of the leathers</p><p>were assessed in dry, wet, and artificial sweat environments. The findings indicate that leathers</p><p>dyed with 1:2 metal complex dyes exhibited superior rub fastness, significantly outperforming</p><p>those dyed with reactive and acid dyes. The commercial shoe lining leather sample tested in the</p><p>study showed lower rub fastness than the all dyed leathers. These results underscore the</p><p>importance of selecting the right dye type and controlling dyeing parameters to enhance leather</p><p>durability. The study offers valuable insights into the mechanisms of dye fastness and provides</p><p>recommendations for improving footwear manufacturing processes, with the potential to reduce</p><p>dye transfer and enhance consumer satisfaction. </p>
