Three times drafting step is: solidify roller 7 around to acid removing roller 11, carrying out drawing-off under the strand warp after the secondary drawing-off; Because of the linear resonance surface velocity of acid removing roller 11 slightly faster than on solidify roller 9 and the linear resonance surface velocity that solidifies roller 7 down; Strand under solidify roller 7 around to acid removing roller 11, being stretched once more, on acid removing roller 11, carry out disacidify simultaneously and handle;
The spinning cake forming step is: the strand after three drawing-offs gets into tophan box 15 and is wound into spinning cake.
At last through alkali cleaning, pickling, the step process of washing, oil, dry then, break into bobbin after the damping, divide grade packaged at last.
Use the test of XL-1 type Yarn Strength appearance, the intensity of spinning finished product can reach 2.5CN/dtex.
Also can under solidify and be provided with four on the roller with drawing-off dish up and down; Last solidify be provided with more than four on the roller on the drawing-off dish; Last drawing-off dish and the precedence of following drawing-off dish according to drawing-off; Last drawing-off dish, down the external diameter of drawing-off dish becomes greatly successively, from the nascent strand of glue-spraying device through acid-sweepping rod around to last drawing-off dish, twine drawing-off from small to large according to the size of last drawing-off dish, time drawing-off dish external diameter then.
