Abstract:

In this study, the effects of braid pattern and take-up rate on the mechanical properties of the tubular braided ropes of polypropylene were investigated. Strand fineness of 70 tex and 150 tex, braid pattern of 1/1 and 2/2, and high & low take-up rates were selected. For both strand finenesses, the highest values for maximum tenacity, modulus and yield tenacity were obtained with the high take-up rate and the 2/2 pattern. However, the highest values for maximum strain and yield strain were obtained with the low take-up rate and the 1/1 pattern. There were statistically significant differences between the results of other mechanical properties, except for the maximum strain value for braided ropes produced with a different pattern. There were statistically significant differences among the results of all the mechanical properties tested for braided ropes produced with different take-up rates.
