【 摘 要 】

Bleached eucalyptus Kraft pulp was acetylated with acetic anhydride under mild conditions, and recycling treatments were performed for acetylated pulp and unmodified pulp. The results indicated that Kraft pulp could be acetylated with acetic anhydride in absence of the catalyst, and hydrophobic acetyl functional groups were introduced into cellulosic fibres. Acetylation can restored the swelling ability of Kraft fibres, inhibit the hornification of Kraft pulp and improve pulp performance with the progress of cycles.
