A high-speed apparatus and method for producing thermoplastic synthetic fibers

摘要

This invention relates to a compact in-line high-speed apparatus for producing thermoplastic synthetic fibers comprising; a) a melt spinning device (1) equipped with a spinning block (9) and a tow drawer (10) wherein the spinning block (9) has at least one extruder, at least one spinneret block (40), and heating means, and the tow drawer (10) draws fibers spun from the spinning block (9) as a bundled tow, b) a drawn tow accumulating device (2) equipped with at least two tow feeding rolls (28) and a tow accumulating conveyer (29) wherein the tow feeding rolls (28) can feed the tow obtained from the tow drawer (10) onto the tow accumulating conveyer (29), and the tow accumulating conveyer (29) can accumulate the tow fed from the tow feeding rolls (28), and c) a high-speed tow stretching device (3) stretching the tow supplied from the drawn tow accumulating device (2) at high stretching speed. It also relates to a method for producing thermoplastic synthetic fibers using this apparatus.
