Abstract

PURPOSE: Unopened tow of synthetic fiber is opened, compressed to give filaments fine scratches, then cut into short fibers to produce novel type staple fiber having good spinnability and giving cloth or high softness and draping property.
CONSTITUTION: A tow of synthetic fiber is opened and the opened tow 1 is compressed with the first compression rollers 2, 2' to form fine scratches on the fiber surface by the compression stress at the crossing points, i1Wi3 between filaments a, b and c. Then, the resultant fiber is compressed with the second compression roller 3, 3' to move the crossing points on the sheet 4 a little to j1Wj3. Further, the tow is treated with rollers 7, 7' and 8, 8' under tension to modify the opening state to give the tow 9 with fine scratches such as l1Wl3, m1Wm3 along the filament length, then made into short fibers to give the objective staple fibers.
