摘要： Provided is a method for manufacturing a glass fiber strand in which a glass fiber strand is formed by bundling a plurality of glass fiber filaments comprising molten glass drawn out from a nozzle, wherein said method for manufacturing a glass fiber strand is capable of detecting breakage of the glass fiber filaments in a more reliable manner. This method comprises: an image capturing step for generating a plurality of items of image data by continuously capturing images of a plurality of glass fiber filaments f; an image processing step for extracting, from the image data, a high luminance object having a luminance of a prescribed value or more; and a breakage detection step for detecting that a glass fiber filament f has broken on the basis of the results of the image processing in the image processing step.

摘要： A highly temperature-resistant glass fiber and a preparation method therefor. The glass fiber comprises 62-66 wt % of SiO2, 14-19 wt % of Al2O3, 15-20 wt % of CaO, 0-2 wt % of MgO, 0-3 wt % of Fe2O3, and 0-1.2 wt % of TiO2, the total content of Na2O and K2O is 0.1-0.8 wt %. By precisely controlling the mixture of the components, the glass fiber has good resistance to high temperature and formability, and significantly increases the high-temperature softening point. The glass fiber has a forming temperature of not exceeding 1380° C., an upper limit temperature of devitrification of lower than 1280° C., and a high temperature softening temperature of 950° C. or above.
