Optical Fiber Image Method For Measuring Cotton Fiber Impurity In Changling, Shaanxi

For a long time, the measurement of impurities in cotton fibers by fiber inspection departments and textile enterprises in our country adopts the weighing method of mechanical separation of impurities. The disadvantage of this method is that the measuring speed is very slow, and the impurities in cotton fibers can not be effectively measured, which can not meet the requirements of fast speed measurement for cotton quality inspection.

An optical image measurement method has been developed by Changling spinning and weaving company.

The technology has a test window, which is equipped with a standard light source on both sides of the symmetry, and has a certain angle with the test window. The lens is mounted below the lens and connected to the camera through an optical regulator. The light source uses a symmetrical tungsten lamp with the same power and the same color temperature to irradiate the tested cotton fibers from a certain angle of the normal surface of the tested cotton fiber surface, ensuring that the illumination of the test window is good and uniform, and the diaphragm is installed on the receiving optical path of the optical system, which helps to reduce the external stray light into the optical system of the cotton fiber color.

This patented technology ensures the stability of the standard light source, stable and uniform illumination of the test window, the design of the optical regulator and the impurity image of the tested cotton fiber is clear and accurate, and the special image processing software for cotton fiber impurities is made by using standard white boards and impurity plates.

It is reported that the patented technology has been successfully applied to the XJ128 fast cotton fiber tester which is newly developed and manufactured by Changling spinning and weaving company. It ensures that the product is fast, comprehensive, accurate and highly automated in testing cotton fiber impurities.
