A literature research is presented concerning the pickup and penetration of starch at the size press. The literature research indicates there is very little quantitative results in this area. The objective of the experimental work is to determine the effect of starch temperature, sheet moisture, and machine speed on the penetration of starch into the sheet. The depth and quantity of penetration was obtained by using a spectrophotometer to determine the concentration of starch in microtomed samples.
The experimental results indicated that increased temperature of starch solutions and increased machine speeds increases penetration. Penetration also increases with increasing moisture content of the paper but only to an optimum moisture content. The effects of penetration and pickup on physical and optical test results are also discussed in the discussion section.
