Effect of TAED activated H2O2 bleaching on the properties and structure of jute fibers

Abstract

Abstract-Both conventional hydrogen peroxide bleaching and tetraacetylethylenediamine/hydrogen peroxide system bleaching were carried out on the scoured jute fiber, and the properties and structures of bleached fibers were compared to estimate the effect of tetraacetylethylenediamine in hydrogen peroxide bleaching. The results shows that tetraacetylethylenediamine/hydrogen peroxide system bleaching could be carried out at lower temperature with a mild alkaline condition, and which is much more effective in removal of noncellulosic materials, especially for color matters and lignin, while causes weaker fiber damage. X-ray diffraction analysis indicates that both conventional hydrogen peroxide bleaching and tetraacetylethylenediamine/hydrogen peroxide system bleaching used in this study does not change the crystalline structure of jute fibers.
