IPC: B29K67/00
Filed: 2001-04-06
Abstract: PROBLEM TO BE SOLVED: To provide a chip composed of PTT having a polymerization degree suitable for fibers for textiles or fibers for materials and capable of industrially stably producing a fiber having excellent strength because of properties without causing fusion of chip to chip or occurrence of powdery polymer and a method for producing the chip.

The resultant chip has high polymerization degree and adequate crystallinity.  As a result, transportation and extrusion of the chip can stably be carried out because of chip scarcely causing heat fusion and clogging of a fan of a pneumatic transport (pneumatic line) or a drier or loss of the polymer can be suppressed, because the producing method can suppress occurrence of the powdery polymer and a fiber having excellent strength can industrially stably be produced, because the production method can suppress unevenness of yarn diameter due to change of extrusion pressure in yarn spinning or occurrence of fluff or end breakage.
