【Abstract】 Based on optical measurement technology, a test device for quickly measuring the cross-section parameters of yarns was designed. Through testing the samples of filament bundle with different linear density and different twist, the influences of linear density and twist on the cross-section parameters were analyzed, and the calculation methods of cross-section test diameter, cross-section test area and cross-section equivalent diameter, cross-section equivalent area, as well as cross-section shape factor were given. The results showed that, the test device could obtain the cross-section parameters of yarns including structural factors, which could provide more accurate cross-section information of yarns for the mechanical property prediction and the quality control of industrial yarns.更多还原
