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.

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.
