Steam explosion and alkali boiling combined degumming of natural bamboo fibers

In order to improve the effect of natural bamboo fiber degumming,the process of steam explosion and alkali boiling combined degumming of bamboo fibers was researched,and the effect of process conditions on the degumming effect of the fibers was analyzed.SEM,FT-IR and strength tester were used to examine the surface morphology structure,chemical composition,and strength of the combined degummed fibers.The results showed that the effect of fibers treated by steam explosion and alkali boiling combined treated degumming was better than that of fibers by single alkali boiling or steam explosion,and the diameter of fiber reduced obviously.Furthermore,the more intense steam explosion conditions,the higher degumming rate,the more scattered,and the better softness of the fibers.The hemicelluloses and lignin were removed from the fibers well,and the cellulose content rose to 63.59%,and the strength and elongation of the bamboo fibers at break were 21.98 cN/tex,3.56%,respectively.
