Electron microscopy, IR spectroscopy, and x-radiography have been used to study the supermolecular structure of guza paya cellulose obtained by the following technological methods: alkaline cook, bleaching with hydrogen peroxide, and acidification; alkaline cook in the presence of anthraquinone, oxygen-soda cook, bleaching and acidification; and alkaline cook in the presence of anthraquinone and hexamethylenetetramine, followed by an oxygen-soda cook, bleaching, and acidification. It has been shown that the structure of the cellulose depends on the method of its production, but changes take place only at the supermolecular level, without affecting the fine structure. |
