Abstract

Generally, it has been know that AKD develops sizing efficiency by forming the chemical bond with cellulose in neutral paper making. However, there have been many expriments in opposition to this theory. This study was carried out to find whether there is chemical bond between AKD and cellulose or not. Also, it was investigated that how much the reacted AKD forming chemical bond and the unreacted AKD contribute to sizing degree respectively if chemical bond presents, and what caused AKD sized paper to migrate under high temperature. Besides, this work experimented several factors having influences on AKD sizing in paper amking.
