The objective of this research was to determine the characteristics and physical properties of paper mulberry yarns spun by different methods. The materials used for this study were the inner barks of paper mulberry trees (Broussonetia papyrifera (L.) Vent.), between 6 to 12 months old.  The paper mulberry yarns were spun by the modified hemp spinning method using 2, 4 and 6 mm strips and the modified cotton spinning method using 3.5, 5 and 6.5 cm fibers.  The yarns produced were tested for physical properties according to the American Society of Testing Materials (ASTM) standards. It was found that the modified hemp spinning methods produced much smoother yarns, but they were still uneven in texture and classified as grade C. In contrast, the modified cotton spinning methods produced fuzzy and rough yarns, more uneven in texture and classified as below grade D. The paper mulberry yarns spun by different methods statistically had different yarn count, yarn twist, yarn breaking strength and yarn elongation at the .01 level. The yarn spun by the modified hemp spinning method using 6 mm strips had the highest yarn count, breaking strength and elongation, while the yarn spun by the modified cotton spinning method using 3.5 cm fibers had the highest yarn twist.
