Abstract:The fine and mature cotton fibers can make it possible to spin a finer yarn, and fineness and maturity of cotton fibers were essential qualitative characteristic, however, there was no direct or indirect measurement method that was both fast and reliable to estimate them. In this paper, a novel method was put forward to assess cotton fiber fineness and maturity based on optoelectronic measuring techniques. The experimental results were compared between the microscope measurement and system measurement and the linear fit results of two measuring methods of that linear fit were 0.98788, and standard deviation was 0.19081. Average cross-sectional widths of cotton samples measured by the microscope and the system had a fairly low correlation with the micronaire data. The linear fit results of the fiber maturity ratio of two measuring methods were 0.95587, and standard deviation was 0.33203. This method can be done in the lab and be used in the industry adherent to the present measurement instruments, for example AFIS, after improved.
