This research objectives were to study and compare moisture, modulus of maximum tensile stress and taxonomy of Cyperaceous rhizomes aging 5 months and years was found that the mean moisture of the fiber from Cyperaceous rhizomes aging 5 months and years were % and % , respectively. The mean modulus of maximum tensile stress of the non-dyed and dye fiber from Cyperaceous rhizomes aging 5 months and years were , , and , respectively. And taxonomy of the Cyperaceous is Sedge (Goke Tagrab-common name) which is classified in Cyperaceae family. It’s scientific name is Cyperus procerus Rottb.
