Tying together the ultrastructural modifications of wood fibre induced by pulping processes with the mechanical properties of paper

摘要: The composition and ultrastructural arrangement of cell wall polymers in wood fibres have determining influence on the properties derived materials. It is therefore important to improve our understanding relationship between organisation, modifications induced by pulping treatments, resulting paper sheet mechanical properties. different treatments which are subjected during manufacturing pulps papers induce morphological micro-structural alterations due removal constituents microfibrillar elements. impact processes was investigated at scale transmission electron microscopy. Particular attention given effects beating refiners various intensities ultrastructure fibres. most characteristic consisted delaminations, microfibril disorganisation, even fractures, varying importance depending intensity refining. consequences internal surface were examined relation Correlations type alteration observed its possible a property suggested. With similar approaches, drying recycling studied.
