PACKAGED CARBON FIBER PRECURSOR TOW, AND METHOD AND DEVICE FOR MANUFACTURING SAME.

摘要

Provided is a packaged tow wherein a carbon fiber precursor tow (1), which has a flattened cross-sectional shape comprising a first surface and on the opposite side therefrom a second surface, is layered and packaged inside a container while in an untwisted state. The front end and back end of the carbon fiber precursor tow (1) are placed on top of the fully-packaged carbon fiber precursor tow. The portion of the tow from the bottom of the package to the tow front end (1a) placed on top of the carbon fiber precursor tow (1) is in an untwisted state. A top/bottom identification means is applied so that the top and bottom of the tow front end (1a) and back end (1b) can be distinguished, thereby making it possible to match the top and bottom surfaces of tow front ends (1a) and back ends (1b) from a plurality of packaging containers (4), preventing fiber breakage from occurring in a flameproofing step due to accumulated heat in twisted parts.
