ABSTRACT:
In a draft roller for fiber, a rubber roller is used as the top roller. A thin amorphous quartz membrane of 0.05 to 5 micron thick is provided on all or part of the surface of the rubber roller to improve both holding of a fiber bundle and abrasion resistance of the rubber surface. It is preferred that the thin quartz membrane contain one or more of carbon black, diamond powder, metal powder or fine olefin tetrafluoride powder in dispersion.
The thin amorphous quartz membrane is formed by applying an organic solvent solution of perhydropolysilazane having a molecular weight of 600 to 1000 on all or part of the surface of a rubber roller, removing the solvent and heating the coated layer.
