Abstract
The present invention relates to a chain, continuous and no-waste method for degumming and fiber-separating the ramie, including anaerobic circle step, in which the raw fibers after the waste alkali bath step are immersed in the anaerobic water pool; aerobic circle step, in which the raw fibers after the anaerobic circle step are immersed in the aerobic water pool; alkali-hydrogen peroxide one bath scouring-bleaching step, in which the raw fibers after the aerobic circle step are immersed in a combined solution of NaOH and HO; and the treatment by a fiber-separating and washing device followed by the immersion in the cellulase solution. In the present invention, the ramie degumming process and the degumming wastewater treatment are performed integratively, and the degumming wastewater is completely recycled after treatment.
