Behavior of Fluid Fibre in Open End Spinning

Quality of Yarns Produced by Japanese Open-End BD-200 Spinning Machines and of Final Products

Yarns produced by Japanese Open-end BD-200 spinning machines give these major advantages: (1) They are somewhat stronger than yarns spun by Czecho BD-200's. (2) They are almost as strong as yarns spun by ring spinning machines. This strength is obtainable without raising the cost of raw cotton if the right fore-spinning processes and spinning conditions are used. (3) They have maximum strength ...

Spinning eggs—which end will rise?

We examine the spinning behavior of egg-shaped axisymmetric bodies whose cross sections are described by several oval curves similar to real eggs with thin and fat ends. We use the gyroscopic balance condition of Moffatt and Shimomura and analyze the slip velocity of the bodies at the point of contact as a function of u, the angle between the axis of symmetry and the vertical axis, and find the...

Oscillating Fluid on a Spinning Rod

Weissenberg observed that when a rod is rotated in a complex fluid, the fluid will climb the rod. When revolutions per time are sufficiently large, climbing ceases and oscillations on the fluid surface begin. Previous studies of this phenomena focus on the regime prior to oscillation; however, this study focuses on understanding these oscillations. By performing a harmonic analysis, wave featur...
