Abstract

In this study, test liner papers in seven different grammage (85 g/m2, 90 g/m2, 95 g/m2, 100 g/m2, 105 g/m2, 110 g/m2, and 115 g/m2) were made from recycled fibers , and effects of grammage on strength properties of handsheets were investigated. The stretch and TEA values of handsheets were increased with increasing grammage. The tensile and tear indices of handsheets were changed irregularly with increasing grammage. On the other hand, burst index of handsheets was not affected with grammage increases. A negative correlation was also observed between the air permeability and grammage of handsheets.

Özet

Bu çalışmada, 7 farklı gramajda (85 g/m2, 90 g/m2, 95 g/m2, 100 g/m2, 105 g/m2, 110 g/m2, ve 115 g/m2) atık kağıt liflerinden test liner kağıtları üretilerek kağıdın sağlamlık özellikleri üzerine gramajın etkileri incelenmiştir. Kağıtların uzama ve TEA değerlerinin gramaj artışları ile arttığı tespit edilmiştir. Kopma ve yırtılma indisi değerlerinin gramaj artışı ile düzensiz bir değişim gösterdiği belirlenmiştir. Diğer taraftan, patlama indisi değerlerinin gramaj değişiminden etkilenmediği tespit edilmiştir. Ayrıca, kağıtların hava geçirgenliği ile gramajları arasında negatif bir ilişki gözlemlenmiştir.
