Method of drawing and heat treating synthetic filaments |
| abstract |
A method of drawing and heat treating undrawn filaments of condensation polymer between a heated feed roller rotating at a constant peripheral speed and a draw roller rotating a constant peripheral speed greater than that of the former, the surface of said feed roller being heated at a temperature within the range of from the second order transition point of said filaments to a temperature 55* C. higher than the second order transition point, characterized in that, A. A PRESSURE ROLLER IS PROVIDED WHICH ROTATES BY CONTACTING WITH THE AFORESAID HEATED FEED ROLLER AND PRESSES AGAINST AT LEAST THE FINAL TURN OF THE FILAMENT WOUND AROUND THE HEATED FEED ROLLER TO THEREBY FIX THE NECKING POINT AT THE POINT OF CONTACT OF THE TWO ROLLERS; AND B. A SLIT HEATER HAVING A GROOVE WIDTH OF 0.5-3.0 MM IS DISPOSED BETWEEN THE HEATED FEED ROLLER AND THE DRAWING ROLLER, THE TEMPERATURE (Y* C.) of the slit heater and treating time (x sec.) being so chosen as to satisfy the following conditions: y > OR = -1770.8 x + 255, 100 < OR = y < OR = 400, and 0.01 < OR = x < OR = 0.12. |
