PURPOSE:To obtain the title fiber having tenacity close to natural kemp and dull gloss and highly similar appearance to that of natural kemp, by putting synthetic fiber undrawn yarns to roller pressing treatment. CONSTITUTION:A undrawn synthetic fiber tow 1 of very high breaking elongation, consisting of thermoplastic synthetic fiber is fed, via a converging guide 2, to one or more pairs of upper and lower metallic press rollers 3 and subjected to pressing treatment. Thence, the resultant tow 5 is fed to a cutter, without drawing, to produce staple fibers, thus obtaining the objective synthetic fiber. |
