A measurement of fiber breakage ratio in combing process

Through analyzing the fiber input and output of a comber,a measurement of fiber breakage in combing is achieved by calculating fiber length distribution by weight and noil percentage.The equation for satisfying the number requirement of the input and output fibers is discussed.The basic principle is the fact that the number of fibers will increase after fiber breakage in combing.The measurements such as fiber breakage percentage and fiber breakage rate tage are defined.The test and calculation only use the fiber length distribution and noil percentage.The method is applied to the comber processing evaluation and has achieved an accurate description of the fiber breakage.Real calculation indicated that a common comber can causes fiber breakage percentage ranging from 1.6% to 3.6 %.The proposed fiber breakage measurement also can be used in other fiber processing system,such as carding and drafting.
