Influence of Opening Force During OE Spinning on Fiber Geometry

摘要

This paper deals with the dynamics of sliver separation into flocks, little flocks, and individual fibers during the OE spinning process. A functional dependence is determined for the opening force exerted on a clamped sliver tuft. The influence of the opening force on fiber geometry simulated with a double helix model is established. Fiber coiling is simulated with a primary helix and fiber crimping with a secondary helix. The decoiling and decrimping forces and the degrees of fiber extendedness as a function of the tensile force during gradual loading are measured for cotton, regenerated cellulose-viscose, and cotton-type PAN and PES fibers. The function of the opening roller rotation speed and the degrees of fiber extendedness during the OE spinning process are established.
