Effects Of Test Parameters On Mechanical Properties Of Jute Yarns

Quality of jute yarn is usually judged in terms of tensile property and irregularity. Tensile property is basically the response of the material to tensile force or extension. Tenacity and breaking extension are most important parameters for jute yarn. Filled in jute bags are stacked in storehouse and the height of the stack is more than 20 ft., when the bags are dropped from the stack the bags are subjected to impact loading on the floor of the store house and reasonably good work of rupture is helpful for preventing the failure of the bag. Initial modulus value may have certain role to take proper shape when the material is packed inside the bags. The tenacity of a textile yarn is dependent on the gauge length and test speed during tensile testing. Studies on the effects of gauge length and test speed on tensile properties of jute yarn have been discussed in this paper.
