Development of the system for testing cotton fiber length

In this paper,a novel method was introduced to test the fiber numberlength distribution of cotton fibers.The sample fibers were combed into a bundle one end flat and the other end uniform and straight along the fiber length direction,then,the bundle was cut into fiber particles with specific length by a fiber amputator,and the particles from different area of the fibers were distributed on a grading board,after that,the images of the fiber particles on the board were taken and transferred into a computer by a scanner and other image analysis equipments.Image analysis arithmetic was used to calculate the number of the particles and figure out the fiber number at different fiber length area,then,different values such as maximum fiber length,mean length based on the number of fibers and standard deviation of fiber number-length distribution were worked out.
