摘要：

Fibre characteristics of kraft softwood and hardwood unbleached and bleached pulps, namely FS number - indicating fibre strength, L number - indicating fibre length and B number - indicating fibre bonding ability, were determined by the PULMAC zero-span tester. A higher tensile index of softwood pulp and unbleached pulps is related to a higher FS and L number and, consequently, to higher strength and length of fibres. On the contrary, hardwood pulps have, at an equal tensile index, a higher B number than softwood pulps. At an equal tensile index, the B number of bleached pulp is higher than that of unbleached pulp.
