Abstract: By using of computer’s dynamic microscopic observation and real-time image process-ing technology,an automatic ramie fiber fineness instrument was designed with selecting and exploiting of relative software of the CCD camera,the 3 D loading platform,the strobe light (synchronizedwith the movement of loading platform),the projection optical microscope,the stepping motor,etc.It can rapidly and accurately determine ramie fiber fineness index:the diameter (d,μm),the metric count (Nm ,m/g),the linear density (ρL,tex)and fiber irregularity (CV,%). The results showed that the instrument was stable and repeatable as well,small error and high accuracy. A ramie fiber sample was detected for 5 min to 6 min and the number of fiber specimens up to 1000/min. The success of developing of the in-strument has filled the gap in the field of the quick determination technologies of fiber fineness of ramie in China and provided guidance of ramie fiber products quasi -determination in ramie scientific research and production.
