INSTALLATION FOR PRODUCTION OF FIBRE MATERIAL OUT OF THERMO-PLASTIC Russian patent published in 2010 - IPC D01D5/08 

FIELD: machine building.

SUBSTANCE: installation is designed for production of fibres out of thermo-plastic by means of supplying polymer melt and/or mixtures of polymers inside heated rotating fiberisator, in forming and simultaneous pulling fibres from jets of melt. The installation consists of an extruder, fiberisator, transporter for fibre collection, system for control and adjustment of temperature in the fiberisator; the system includes an optical pyrometre, power source and inductor. Notably, the rotating vertically installed fiberisator heated from the inductor is made in form of a cylinder with internal surface formed with a truncated cone, where angle between a shaft axis and an internal wall of the fiberisator is not less 30° and not more 35°, and with a lower truncated cone of the fiberisator where angle between a vertical axis of the fiberisator and cone generatrix is 45-60°. In a bottom part of the fiberisator and along circumference there are made openings; melt of thermo-plastic material flows via the openings under effect of centrifugal forces at fiberisator rotation. Angle of incline of secant flow of air from the opening of the inductor relative to vertical axis of the fiberisator is not less 10° to facilitate air flow directing formed fibre to a side opposite to the fiberisator. Diametre of produced fibre is adjusted by velocity of rotation and temperature of fiberisator walls, while output is determined with diametre and number of the openings in the fiberisator.

EFFECT: upgraded quality and physical-mechanical properties of produced fibre and reduced losses of source raw material due to destruction.
