PEROXIDE PULPING PROPERTIES OF ANNUAL PLANTS. 3. DIMENSIONAL CHARACTERISTICS OF FIBERS OF WHEAT STRAW
Abstract
Dimensional characteristics of peroxide cellulose fibers (received by means of delignification with reaction mixture «H2О2 – H2О – AсОН – АсООН – catalyst») and sulfate cellulose fibers from stems of wheat straw was studied by using L&W Fiber Tester (properties of sulfate cellulose fibers there are in the brackets): the number of fibers in the 1 g 20,0×103 (20,1×103); weight mean length 1,34 (1,22) mm; arithmetic mean length 0,577 (0,509) mm, weight mean width 19,3 (17,8) µm; arithmetic weight mean width 17,8 (16,8) µm; wall thickness 1,65 (1,65) μm; coarseness 0,158 (0,109) mg/m; shape factor 90,7 (86,3)%.
