The acoustic emission(AE) characteristics of tensile damage processes in PE fiber was studied by means of testing. By using AE multi-parameter analysis, the AE characteristics of different damage phases were defined and AE parameters of different damage types were obtained. The research indicated that the determinant rule of PE fiber invalidation occured when the AE extent was more than 90 dB and the duration was more than 1042 μs.
