An Essay on the Fine Structure of the Wood Cell Wall Related to the Physical Properties of the Recycled Paper
Remarakable progress in microscopic techniques from the 1950’s to the 1960’s enabled plant anatomists to clearly describe the fine structure of the wood cell wall. Nowadays, it is our common knowledge that each lamella can be approximated by a “two-phase structure”, i.e. the reinforcing element of cellulose microfibril (CMF) and the matrix (MT) substance of lignin-hemicellulose compound. However, an exact image of the fine structure and the functions of each cell wall constituent has yet to be clarified. For better utilization of the wood as the engineering materials, it is indispensable that such characteristics should be revealed. However, it is still difficult to measure the complicate properties of each cell wall constituent directly as it is in the cell wall.
