Abstract

The purpose of this paper was to determine the feasibility of using a pulping aid with a polysulfide kraft cook. Since any change in an operation such as pulping must yield a product such that the quality is better or not appreciably reduced and at the same time must be economically acceptible, the feasibility was based on these factors. Tests were made on a standard kraft cook, a polysulfide cook, a cook using the pulping aid alone and a cook using the pulping aid with the polysulfides. From the work conducted, there were no significant changes in the physical and optical tests performed while at the same time, a slight increase in the yield over the standard kraft cook was noted.
