Beschreibung
Zusammenfassung:	Various embodiments directed towards methods of applying sizing to fibers are disclosed herein. In some embodiments, solvent can be used to dissolve a sizing material into a solution, which can then be used to coat the fibers. In some embodiments, a water bath is used to coagulate a sizing on the fiber surface and to remove the remove solvent after coating the fibers, so that water vapor can be created during a subsequent drying step as opposed to solvent vapors. In some embodiments, strong acids or strong bases can be used as the solvent.
