The Behaviour of Fibre-to-Fibre Bonds in Sheets Under Dynamic Conditions

Abstract

Using the techniques described in a previous paper, a study has been made of the breakage of fibre-to-fibre bonds in paper sheets under tensile strain . The frequent occurrence of partial separation in the areas of bonding and the relative rarity of total breakages are of particular interest. The way in which the bonded area loss is distributed between the bonds has been examined with particular reference to the effect of drying tension and beating . Both partial and total breakages are more common in freely dried sheets than in sheets dried under tension. Possible reasons for the occurrence of partial bond breakages are discussed.
