Abstract
The objective of this study was to determine the effect secondary fiber has on the burst and tensile of the paper sheet. There are many different physical aspects to burst and tensile and these aspects are discussed in some detail. Previous work has been performed in similar areas. The data and conclusions from that work was extremely helpful to this study. The literature search revealed several theories of the relationship between burst and tensile. The theory which this study investigates is the Carson linear relationship model.
The handsheets which were produced had varying amounts of secondary fiber. They also contained some alum and rosin to similate production requirements. The secondary fiber used in the handsheets were treated to excessive drying to produce the correct amount of hornification.
The results of the study are conclusive. The secondary fiber does effect the burst and tensile. However, it effects both of them to the same degree. The relationship between the two remains linear. When the data was used to calculate the radius of curvature, it showed more stretching the fiber network as the percent of secondary fiber increased.
