The influences of the slot width of the attenuator on the properties of PET spunbonded fibers were studied, and Fourier transformation infrared spectrophotometry (FT-IR) and Wide-angle X-ray diffraction were applied to characterize the crystalline and orientation structure of PET spunbonded fibers as well. It was found the attenuator with positive air pressure is more advantageous to spin PET spunbonded fiber and the fiber becomes finer and its' tensile strength becomes higher with the decrease of the slot width. The air speed in the attenuator was predicted as well. Springer Science+Business Media, LLC, 2007 Wang Hong Nonwovens R & D Center, Donghua University, 200051, Shanghai, P.R.
