Title:
弱い繊維結合を有する木材を得る方法
Document Type and Number:
Japanese Patent JP3927604
Kind Code:
B2
Abstract:
A method and an arrangement for obtaining wood in which the tracheids have less ability to bind to each other. The end surface of the wood is irradiated with pulsed laser light of such strength, and with such a number of pulses, that lignin-related cellulose and hemicellulose bonds break up along the light-conducting middle lamella to a depth which is sufficient to ensure that reduction of the wood (to paper pulp) via mechanical processes can be done more quickly, more gently and with greater efficiency.
