METHOD FOR IMPROVING BIODEGRADATION RESISTANCE AND DIMENSIONAL STABILITY OF CELLULOSIC PRODUCTS

摘要

The invention concerns a method for improving the resistance of cellulosic products against mould and rot as well as for enhancing the dimensional stability of the products. According to the method the cellulosic products are subjected to a heat treatment which is carried out at an elevated temperature. According to the invention the products are dried to a humidity of less than 15 %, and then they are kept in moist atmosphere at a temperature of at least about 150 DEG C for typically 2 to 10 hours until a weight loss of at least 3 % has been obtained.
