Lotus silk is a natural fiber with high economic value; however, current production remains largely manual, resulting in low productivity and limited scalability. This study experimentally investigates the length of lotus fibers drawn under the influence of processing parameters, including storage time, lotus stem diameter, cutting depth, and the length of the lotus stem segment involved in the extracting process. Experiments were conducted with 108 combinations, and the data were analyzed using analysis of variance (ANOVA). The results indicate that the effective extracted stem length is the dominant factor influencing fiber length, followed by post-harvest time and stem diameter. The interactions between post-harvest time × stem diameter and cutting depth × post-harvest time were found to have significant effects. Furthermore, the lotus silk yield reached 102.4 mg per kg of fresh lotus stems. These findings provide an initial quantitative basis for the development of mechanized solutions for the lotus silk extraction process.
