摘要： A fiber instrument for measuring properties of a fiber sample, the fiber instrument having a surface for receiving the fiber sample, a hand for pressing the fiber sample against the surface, an illumination source for selectively illuminating the fiber sample with more than one peak wavelength, where each of the peak wavelengths is independently controllable as to an applied intensity of the peak wavelength, a sensor for capturing images of the fiber sample while it is illuminated, and a controller for controlling at least the sensor and the illumination source. By providing multiple peak wavelengths of illumination that are each independently controllable as to illumination intensity, the fiber instrument as described herein is better able to detect both foreign material within the fiber sample, and color gradations of the fiber sample.

摘要： A fiber classing device having a sample window for viewing a fiber sample. A light source provides light that is directed toward and reflected by the fiber sample, producing reflected light. A photo sensitive detector is positioned to receive the reflected light, and it detects lightness, redness, and yellowness of the fiber sample. Processing means assign a preliminary grade to the fiber sample based at least in part on the lightness and yellowness of the fiber sample. The processing means also selectively adjust the preliminary grade to a final grade based at least in part on the redness of the fiber sample. The photo sensitive detector has one or more of a spectrometer, a camera, or a set of three photo diodes. A first photo diode detects light with a wavelength of between about 505 nanometers and about 605 nanometers, corresponding to the lightness of the fiber sample. A second photo diode detects light with a wavelength of between about 430 nanometers and about 530 nanometers, corresponding to the yellowness of the fiber sample. The third photo diode detects light with a wavelength of between about 550 nanometers and about 650 nanometers, corresponding to the redness of the fiber sample. The processing means analyzes the information from the photo sensitive detector to determine the mean redness, variance in lightness, variance in redness, variance in yellowness, contrast in lightness, percent of yellow spots, and contrast in yellowness of the fiber sample. The selective adjustment from the preliminary grade to the final grade is based at least in part on these parameters.

摘要： An apparatus for processing a sample of fibers and trash, having a cylinder for receiving the sample. Pins extend from the surface of the cylinder and retain the fibers. A knife extends along the cylinder adjacent the pins, and removes the trash that is not retained by the pins. The trash is separated from the sample along a downward direction. A counter-flow of air in an upward direction is directed towards the cylinder, where the velocity is sufficient to blow the fibers that are not originally retained by the pins up toward the cylinder, and yet is insufficient to prevent gravity from pulling the trash downward.

摘要： A fiber quality monitoring apparatus is constructed with a sample window for viewing a fiber sample. As the fiber sample passes the sample window, a bulb is strobed to produce a light pulse that is directed toward and reflected by the fiber sample. When the light pulse reaches a desired intensity, a first photo diode generates a synchronization signal. A second photo diode detects reflected light with a wavelength between about 500 nanometers and about 600 nanometers and produces a reflection signal. A third photo diode detects reflected light with a wavelength between about 430 nanometers and about 530 nanometers and produces a color signal. A charge coupled device camera is positioned to receive the reflected light pulse. The charge coupled device camera has an array of pixels which receive the reflected light pulse. Pixels receiving the reflected light pulse at an intensity below a desired value are designated as dark pixels and pixels receiving the reflected light pulse at an intensity greater than the desired level are designated as light pixels. A prism focuses the reflected light pulse received by the second and third photo diodes, and a transparent block encloses the strobing Xenon bulb and the first photo diode so that the light pulse is conducted from the Xenon bulb to the first diode. Processing means analyze the color signal and the reflection signal and produce a composite value, and a percentage value representing the percentage of dark pixels in the array of dark and light pixels. Furthermore, the processing means recognizes and classifies patterns of dark pixels in the array of light and dark pixels, and controls fiber processing equipment in response to the composite and percentage values.

摘要： A method for measuring the weight of impurities in a mixed volume of fibers and impurities by mechanically separating the impurities are from the fibers, whereupon some undesired fibers still remain admixed to the impurities due to imperfections of the mechanical separation. A total weight of the separated impurities and the undesired fibers is gravimetrically measured. An image of the separated impurities and the undesired fibers is created. A weight of the undesired fibers is estimated from the image. The estimated weight of the undesired fibers is subtracted from the total weight to yield a corrected weight of the impurities. The mechanical separation and the subsequent electronic correction yield a more accurate weight of the impurities.
