During the paper manufacturing process, many scientific processes are manipulated to control the physical properties of the paper such as weight, thickness, color, strength, and moisture. While most of these variables remain fixed after the paper is made, the moisture content begins to change almost immediately.

Nanotechnology, as it applies to doctor blades, is a microscopic filler material that is used to enhance the doctor blade performance. It’s added to resin to make the blade denser with higher peel strength and improved chip resistance. This stands out from a typical composite blade and allows for better wear resistance and roll cleaning.

Dryer fabrics, often called dryer “felts”, are used to hold paper against the outer surfaces of steam-heated drying cylinders. The pressure from the dryer fabrics increases the rate of heat transfer from the dryer to the paper. The pressure that is applied to the paper depends on the fabric tension and the diameter of the dryer. The pressure can be calculated, as a first approximation, by the equation:
