Özet

The leather industry, in foundation of Turkish economy, is a labor-intensive branch of industry that takes an important part among textile and related branches of industry; by processing hides or skin of bovines and ovines, makes them eligible for production of various manufactured goods. The present leather products involves many varieties like saddlery, sole leather, technical work ware, hides and furs, leather clothing etc. However, alongside these variations, demands for leather products across the globe are influenced from strategies of societies aiming environmental protection. Developing environmental consciousness, increase of sensibility for ecologic issues and legal legislations leads industrialists to choose methods that have less damage to environment and to produce goods obtained by these methods. Increased environmentalism propagandas have influence on derivation of new leather types named as "Eco-leather", "Bio-leather", "Chromium free-leather". In leather production, this worldwide searching issue proposes new studies for the agenda. New products and production processes designs in which bestavailable techniques, clean technologies are used and environmental impacts are minimised during along an innovative conversion. In this study, various tanning combinations were implemented among alkali aluminosilicates which is a kind of zeolite, vegetable and vegetable-synthetic tanning matters and aluminum triformate. It was attempted to specify whether alkali aliminum silicates have tanning effect or not, and which combination provides the most appropriate results as for tanning quality. Leather samples that were procured in pursuant of these combined tanning methods were tested and analyzed in physical and chemical terms, the results were evaluated by comparing according to accepted standards for garment leathers.
