| titleOfInvention | Measurement method of silica adhesion amount of synthetic fiber |
| abstract | An object of the present invention is to provide a method of measuring the amount of silica adhesion of a synthetic fiber to which an oil agent containing colloidal silica has been attached, which can be used for process control of a production process. SOLUTION: A process of preparing a standard sample containing an oil agent and a silica standard solution, a process of processing a synthetic fiber to prepare a test sample, and ammonium molybdate mixed under acidic conditions for the standard sample and the test sample Color from yellow to yellow and then measuring the absorbance of at least two wavelengths of wavelength 1 in the range of 385 to 440 nm and wavelength 2 in the range of 500 to 700 nm, and calibration from the absorbances of the measured two wavelength standard samples Forming a line, and calculating the silica adhesion amount from the measured absorbance and calibration curve of the two-wavelength test sample, wherein the step of preparing the standard sample and the test sample includes an oil or colloidal silica A method of measuring the amount of attached silica, which comprises a process of mixing and boiling synthetic fiber attached with oil, water and sodium hydrogen carbonate.
