Abstract

Bu çalışmada; deri işlem basamaklarında hidrojen peroksidin alkali ortamda Na2S’ün yerine kullanılması ile yüksek oranda kirlilik yüküne sahip geleneksel kıl giderme-kireçlik işlem basamaklarının yanında enzimatik sama işleminede alternatif olup olmayacağı, mamul deri özellikleri üzerine etkisi ve atık sularındaki atık yükleri araştırılmıştır. Hidrojen peroksidin kıl giderme/kireçlik ile lif açılımı performansının yeterli olduğu, derilerin fiziksel özelliklerinin ve hava geçirgenliği değerlerinin geleneksel yöntemlerle işlenen deriler kadar iyi olduğu ve işlentiler sonunda atıksulardaki KOİ ve sülfit değerlerinin son derece düşük olduğu tespit edilmiştir

USAGE OF HYDROGEN PEROXIDE IN LEATHER MANUFACTURING PROCESSES AND ITS EFFECTS ON LEATHER CHARACTERISTICS

Abstract

In this study, hydrogen peroxide usage instead of sodium sulphide (Na2S) under alkaline condition in leather manufacturing was investigated, whether hydrogen peroxide could be an alternative to high pollutant conventional unhairing-liming process or not. Besides, the effect of hydrogen peroxide on leather properties and the pollution load of liming wastewater were studied. The results indicated that the unhairing and fiber opening performance of hydrogen peroxide were satisfactory and the physical characteristics of the leathers as well as the air permeability values were comparable to those obtained by conventional unhairing-liming process. In addition, the chemical oxygen demand (COD) and the sulfide values of the waste water were also lower than the conventional one
