A method for manufacturing a glass fiber. |
摘要 |
<p>A method for manufacturing a glass fiber having a polygonal cross section is provided. According to the method, a glass fiber having an orbicular cross section is manufactured by drawing molten glass supplied into a crucible heated at higher temperatures than a softening point of glass out of a nozzle having an orbicular cross section heated at lower temperatures than the heating temperature of the crucible and at higher temperatures than the softening point of glass. Then, the glass fiber is passed through a slit of a twin roller, having a predetermined shape, whereby glass fibers having a polygonal cross section are successively manufactured. The twin roller is heated at slightly higher temperatures than the softening point of the glass. <IMAGE></p> |
