Method for manufacturing ligneous material

A method for manufacturing ligneous material, the method comprising:

• preparing first wood fibers which are acetylated with a first degree of acetylation, and second wood fibers which are not acetylated, wherein said first degree of acetylation measured in weight percent gain is 7% or greater;
• and
• binding a first amount of said first wood fibers and a second amount of said second wood fibers with a binder to form a composite,
• wherein said binder comprises polyisocyanate and a thermosetting resin, the content of said polyisocyanate is 50% by weight or greater with respect to the a amount of said binder, and wherein the average degree of acetylation measured in weight percent gain of said composite is 7 to 18%, and
• wherein said first wood fibers have a diameter of 0.1 to 1.0 mm.
