STUDY ON COTTON STEM FOR CELLULOSIC INDUSTRIES

In order to investigate the possibility of utilizing cotton stem in cellulosic industries chemical, physical and anatomical properties of cotton stem (var. varamin) was investigated.Cotton wood fiber length, fiber diameter, lumen diameter and cell wall thickness was measured at 840 mm, 23.9mlm, 16/1...
