Fiber orientation and strength of staple yarns based on the acoustic and initial modulus
Original language description
It is well known that twist has crucial influence on the mechanical properties of short staple fiber yarns. The possibilities of prediction of twist influence on the fibers orientation in the staple polypropylene yarn are discussed in this work. The mainstructural factors which are significant for yarn strength prediction are packing density and orientation factor. These factors are influenced by raw material properties, technology of yarn production, yarn fineness and twist (yarn twist factor). For monitoring of the influence of the twist factor on the yarn packing density, orientation factor and strength of three groups of thirteen compact polypropylene yarns of the same fineness with different twist were spun. It was found that for prediction of orientation factor it is possible to use sonic modulus of yarns and parallel fiber bundles. From packing density, yarn diameter and tangent of helix angle the orientation factors were calculated. The packing density and orientation factor w
