    Abstract

    Fibrillation (axial splitting) of uniaxially oriented, thin tapes of polyolefin polymers critically affects the production rates and quality of woven sack fabric. A test method based on tensile testing of the twisted tape is described that will prove useful to monitor the day-to-day routine testing of tapes for fibrillation behavior. The test method lends itself to standardization for use in commercial laboratories, requiring simple sample preparation and apparatus. For the general procedure, fibrillation strength of the large number of tapes of various molecular orientation indices were measured using the proposed test method. The results obtained show a good correlation between the molecular orientation index and fibrillation strength of tapes.
