Abstract: The physical and mechanical properties of the nettle fibers were studied. Its micro-structure was observed and the obsorbent quality was analyzed. The results show that the main length of nettle fibers is short,varied by large ratio,especial the shorter fibres below 20 mm,the nettle fibers have strong power to drive water in spread and there is relationship with the nettle fibrous construction closely.This research could be used to develop nettle products.
