By setting the retting duration of 20 hours, the factors affecting the residual gum percentage of the retted kenaf fibers are studied. The experimental results show clearly that the following factors have the significant influence on the residual gum percentage of the retted kenaf fibers and show the obvious variation tendency. The preferred processing parameters are as follows: pH value 7. 0、bath ratio 1: 50、reuse percentage of retting liquid 50%、air flow volume 2. 5L/min、temperature 40℃、nitric additives (ammonia is better than nitrates) percentage 0.45%.By comparison with anaerobic retting, the retting duration using aerobes is much shorter than that using anaerobes.
