Nanofiber assembly by rotary jet-spinning.
High-voltage electrical fields and low production rate limit electrospinning, the electrical charging of polymer liquids, as a means of nanofiber fabrication. Here, we show a facile method of fabrication of aligned three-dimensional nanofiber structures by utilizing high-speed, rotating polymer solution jets to extrude fibers. Termed rotary jet-spinning, fiber morphology, diameter, and web poro...
متن کاملQuality 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 ...

متن کاملOn the Jet-driven Axisymmetric Thin Liquid Film over a Spinning Disc
We consider the steady laminar annular spread of a thin liquid film generated by a circular jet impinging perpendicularly in direction of gravity on the centre of a horizontally rotating disc (figure 1). The individual flow regimes arising due to the largeness of the Reynolds number formed with the radius of the jet, its slenderness, and the relative magnitude of the centrifugal force measured ...
متن کاملSpinning 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...
