Effect of Different Degumming Treatments on Morphological, Physical, and Chemical Properties of Hierochloe odorata Fibers

The aim of this research is to investigate the effect of different chemical combinations in degumming of Hierochloe odorata fibers. The degumming processes were established to ensure minimum strength loss of Hierochloe odorata fibers. Structural, morphological, chemical, and mechanical properties of the Hierochloe odorata fiber were examined according to the varied degumming procedures. It is very clear that the degumming procedure has a very significant influence on the fiber properties. A solution of sodium hydroxide (5%) and sodium chloride (1.72%) treatment increased the cellulose content of Hierochloe odorata fibers from 65.88 to 94.70%. All degumming processes lead to an increase in the tensile strength of the fibers, while the highest strength has been obtained for the degumming procedure contain 5% NaOH, 72% NaClO₂, 85% Glycerol (H4) with a value of 150 MPa. As a result, all degumming contents in this study can be used to process Hierochloe odorata fiber, especially in terms of mechanical properties H4 process can be suggested.
