摘　　要：It is important to measure wool diameter as the wool quality depends on the fibre diameter D and its deviation CVD. According to IWTO standards, the fibre diameter parameters can be tested with the methods of Airflowmeter, DA; Sirolan-Laserscan, DL and CVDL; and OFDA, Do and CVDo. However, these parameters only characterize the average diameter and the variation between the fibres. A single fibre analyzer (SIFAN) can be used to measure fibre profile along the fibre and fibre tensile properties simultaneously. The results obtained from the four methods show that there are i) high relationships between Laserscan values and the results of Airflow, OFDA and SIFAN in the average diameters; ii) correlations between CVDL and CVDo or CVDave; iii) the high correlation between Dave-Dmia but a low correlation between Dave-Dmax; and iv) the relationships between the wool quality and the ratio of Dmln/Dave and Dmin/DL. Based on the results and discussions, the effective measurement of wool diameter should be the SIFAN method. The new parameters of Dmin/DL and Dmin/Dave are the useful value for the evaluation of wool quality in practice.It is important to measure wool diameter as the wool quality depends on the fibre diameter D and its deviation CVD.
