This paper presents the second part of a study of deinking using wort. Physical properties of deinked pulps such as tensile strength, bursting strength and tearing resistance were investigated. In order to analyze the properties, the fiber length and coarseness of deinked pulp was also measured. Results of deinking experiments showed that the deinking efficiency of enzyme treatments was higher than that of chemical treatments in strength properties such as tensile strength, bursting strength and tearing resistance on the the whole. we think that the reason why is that the fiber length and coarseness of deinked pulp with wort are more increased and decreased than those of deinked pulp with chemicals individually.
