Abstract
The repeated action of compression-decompression pulses on a wet web of fiber, created by dropping a weight from a height, loosens the internal structure of the fiber. The impaction of fiber did not cause any change in average weighted fiber length, fine content or Canadian Standard Freeness. The sheet made from these fibers showed an increase in tensile strength with increased number of impacts or impact intensity.
In a blend of impacted fibers (internally fibrillated), abraded fibers (externally fibrillated) and fines (fibers shorter than 0.23 mm and created by prolonged beating in a Valley beater), fines were found to be the most influential effect on paper property development.
