Abstract
In this paper, the Rubiaceae Chinese Fevervine stem was used as raw material, with pool dipping, manual decorticating, acid dipping and sodium hydroxide scouring twice as the degumming method, to produce Chinese Fevervine Fibre (CF fibre). Through an orthogonal experiment, optimised two-fold sodium hydroxide degumming using refining technology was achieved: in the first alkali degumming, the NaOH concentration was 1.4% at a temperature of 95 °C for 3.5 hours; in the second , the NaOH concentration was 0.8% at a temperature of 95 °C for 2.5 hours; and in the acid dipping, the sulfuric acid concentration was 6% at room temperature for 0.5 hours. The CF fibre produced has a spinnability of 39.90 mm length, a linear density of 2.82 dtex, a tenacity of 18.56 cN/dtex, and a break elongation of 2.81%.
