Abstract:

The tensile property of regenerated bamboo yarn of 14.58 tex was studied using an HD021N single yarn tensile tester at different tensile speeds (100, 500, 1000, 2000, 3000, 4000, and 5000 mm/min). It was observed that the distribution on diagrams of the breaking strengthfrequency and elongation at break frequency of yarn is normal. The breaking strength of the yarn increases when the tensile speed varies from 100 mm/min to 3000 mm/min, then the strength decreases greatly with an increase in tensile speed. The breaking time of the yarn decreases with an increase in tensile speed. A non-linear three-element viscoelastic model was used to simulate the tensile property of the yarn at various tensile rates. The relative error between the theoretical tenacity and actual tenacity is bound to be less than 3%.
