Abstract In the spinning process the filaments leaving the spinnaret in a vertically downward direction pass through a first coagulating bath and the fluid entrained by the filaments is decelerated by means of concentric angularly directed jets of fluid prior to passage through a second coagulating bath. The filament may then pass-over a bar which changes the direction of the filament and removes entrained fluid. Further coagulating bath treatment may be provided by passage through the trough of a saddle guide prior to passage between a pair of vane type rolls for shaking the remaining bath fluid from the filaments. The filaments are then loosely deposited on a travelling web for further treatment. Specific apparatus for carrying out the process is provided including elastic covered vanes on the rolls as well as several embodiments for the decelerating fluid jet arrangement.
An apparatus for use in a continuous wet spinning process comprising a pair of oppositely rotating rollers adapted to receive the travelling filament therebetween, each of said rollers being provided with a plurality of radially extending vanes having an elestomeric coating thereon, said rollers being spaced such that the vanes of the rollers are disposEd in partial overlapping engagement with each other whereby the filaments will be vibrated to accelerate the centrifugal drive-off of water entrained by the filaments in the form of fine droplets.
