Boraks inorganik kimyasallar sınıfındadır ve alev geciktirici olarak farklı sektörlerde kullanılmaktadır. Boraks yüksek tutuşma sıcaklığına sahiptir, yanma sırasında toksik gazlara neden olmaz ve çevreyi kirletecek emisyonlar yaymaz. Bu çalışmada, ilk olarak wet blue derilerin retenaj işlentisi yapılmış ve ardından finisajı yapılmamış deriler ilk olarak, boraks kimyasallarının fiksasyonunu arttırmak için atmosferik basınç plazması içeren argon gazı ile modifiye edilmiştir. Daha sonra 0, 30 g/L, 40 g/L, 50 g/L boraks çözeltisi padding tekniği ile modifiye edilmiş derilere uygulanmış ve deriler standart bir finisaj reçetesi ile mamul hale getirilmiştir. Derilerin alev geciktirici özelliği limit oksijen endeksi (LOI) (ASTM D 2863-77) alev dayanımı testi ve TGA analizi ile belirlenmiştir. Ek olarak, modifiye edilmiş deriler FTIR, SEM ve Hidrofilite analizleri ile değerlendirilmiştir. Elde edilen sonuçlarına göre, 30 g/L, 40 g/L, 50 g/L boraks uygulanmış deri gruplarının LOI değerleri sırasıyla %29.2, %30.5 ve %31.2 olarak tespit edilmişken kontrol numunesi için bu değer %19.0 olarak belirlenmiştir.
Boraks belongs to the class of inorganic chemicals and is used in different industries as a flamming retardant. Boraks has a high burning temperature, does not cause toxic gases during burning and does not spread emissions that will pollute the environment. In this study, it was first made the retention process of wet blue skin and then the skin not finished was modified with argon gas containing atmospheric pressure plasma to increase the fixation of borac chemicals first. Later, the 0.30 g/L, 40 g/L, 50 g/L borac solution was applied to modified skin with padding technique and the skin was prepared with a standard finishing recipe. The fever delaying properties of the skin are determined by the limit oxygen index (LOI) (ASTM D 2863-77) fever resistance test and TGA analysis. In addition, healed skin is defined by FTIR, SEM and Hydrofilite analyses. According to the LOI results, 30 g/L, 40 g/L, 50 g/L boraks were 29.2%, 30.5 and 31.2%, respectively, while the control sample was 19.0%.
Borax is in the class of inorganic chemicals and is used as flame retardancy in different industries. It has high ignition temperature, does not cause toxic gases during combustion and does not emit emissions that will pollute the environment. In this study, retanning process of leathers was made according to upholstery leather recipe and then the leathers were modified with argon gas containing atmospheric pressure plasma to increase the fixation of borax chemicals by surface modification effect of plasma. Then, 0, 30 g/L, 40 g/L, 50 g/L of borax solutions were applied to the modified leathers by padding technique and the leathers were finished by standard finishing recipe. Flame retardant property of leathers was determined by limit oxygen index (LOI) (ASTM D 2863-77) fire resistance test and TGA analysis. In addition, the treated leathers were characterized by FTIR, SEM and Hydrophilicity analyses. According to the obtained results, 30 g/L, 40 g/L, 50 g/L borax applied leather groups had 29.2%, 30.5% and 31.2% LOI values respectively, while control sample had 19.0%.
