This thesis was designed to determine the effects of moisture on the penetration of size solution into a paper sample. The experiment involved use of laboratory equipment and procedures to accomplish the objectives of this experiment.

Handsheets were conditioned, sized, cut, stained, and viewed under a laboratory microscope to obtain the desired results. The results from this procedure determined that the area of size deposition was dependant upon the moisture content of the paper sheet. As the moisture content of the samples increased, the size was retained more on the sample's surface as opposed to penetration into the paper web.

If the results obtained in this study can be reproduced on the machine scale, extensive capital benefits will be realized by the particular mill. The benefits will be in the form of increased production as well as a reduction in steam consumption. However, benefits obtained from this increase in moisture should be weighed against effects on strength as well as other problems associated with high moisture content utilization, such as moisture profile.
