The molecular orientation acquired during fiber formation of acrylic fibers by wetspinning has been studied. Orientation was detected by measurements of sonic modulus which were converted into an orientation factor. The orientation correlates very well with the ratio of take‐up velocity to the freely extreuded velocity. Several mechanisms for the origin of spin orientation are discussed.
