Özet
The fact that leather's surface of use is brought touch and appearance in an unusual way has become the main objective of finishing in recent years. Because some surface defects cannot be overcome with a classic type finishing, it possible for them to be evaluated with coating techniques. Coating must be aimed at obtaining an alluring product besides its compatibility with the leather properties' being important and in addition to its overcoming the surface defects. In the study, we conducted some studies on the evaluation of the leathers, which are of low quality and contain surface defects, aiming at obtaining different surface characteristics. We aimed to bring ease of use and alternative appearance and touch by creating a fibrous surface through the covering of the flocked, which is an important group of synthetic leathers, and alcantara's applicaitons on leather. In order to obtain an effective fibre surface in different patterns and smooth applicaitons, different binder types, flock formulations and flock fibres were tried, their characteristics were determined thanks to imaging techniques and the sufficiency of fibres' bindings were examined through some physical tests. According to the results, it was observed that in the products of bag, shoes, dress and accessories, on which fantasy appearance and different patterns were applied, polyurethane binder is at the sufficient level and it brings in more superior binding characteristics than acrylics binder.
