主　　题：synthetic fiber cutter blade sharpness measurement 

摘      要：Quantitative measurement of the cutter blade sharpness is yet a difficult problem, since so far there has been no appropriate testing method. In this paper, a technique is introduced for measuring the cutter blade sharpness at different testing conditions. The sharpness of cutter blades are measured by detecting the force to cut off the fiber with a material strength testing machine, and the results indicated that the technique could be used to measure the cutter blade sharpness satisfactorily. The fiber tension and downward speed of cutter blades are recommended to be 4.9 cN and 50 mm/min respectively for cutting 0.22 mm PET fiber.
