| 摘要 |
The invention relates to various methods for the acetylation of lignocellulosic fibres such as jute, hemp, wood fibre, sisal, tow, straw and the like, and involves the mixing of the lignocellulosic material acetic anhydride in such quantities as to effect a 20 % weight gain of the material on completion of the acetylation reaction, and also adding energy to the mixture to catalyse the acetylation reaction. The energy may be ultrasonic, thermal, or in the form of microwave radiation.
