Abstract: In order to make full use of agricultural biotic resources and enrich natural vegetable fibers for textile industry, chemical degumming of okra fibers was explored in both theoretical and practical aspects. The chemical components of okra fiber were determined by chemical analysis. The chemical degumming of okra was studied through adopting two boiling and boiling –bleaching methods in the experiment. The additives, such as JFC, Na2SiO3 and urea, have been successively added in the progress of alkali boiling. Then the effect of additives on the removal of gelatin was analyzed. The longitudinal structures of the okra fibers before and after degumming were examined by scanning electron microscopy (SEM), and their tensile strength was tested. The result showed that the main chemical components of okra fibers are as follows: 50.8% cellulose, 20.21% hemi-cellulose and 16.66% xylogen. Boiling-bleaching is an effective degumming method for okra fibers, and the property of the okra fibers degummed by this method is similar to that of the degummed jute technical fiber.
