Strength prediction of staple yarns based on the acoustic and initial modulus
Original language description
For monitoring of the influence of the twist factor on the yarn packing density, orientation factor and strength, three groups of total thirteen compact polypropylene yarns with same fineness and different twist factor were spun. It was found that for prediction of orientation factor it is possible to use sonic modulus of yarns or other parallel fiber bundles. From packing density, yarn diameter and tangent of helix angle the orientation factors were calculated. The packing density and orientation factor were also used for prediction of yarn strength.
