Abstract In this study, waste cotton fabric was used as cellulose raw material and
pretreated in aqueous NaOH/urea solution system to investigate the effect of
NaOH/urea pretreatment solution on the hydrolysis of cotton fiber. The cotton
fiber was pretreated with different conditions of aqueous NaOH/urea solution,
and the pretreated cotton fiber was hydrolyzed under the same conditions as
the original cotton fiber. The results of characterization analysis showed that water
retention value of pretreated cotton fiber was higher than that of unpretreated sample. Moreover, the cotton fiber presented both a convoluted structure and a coarser
surface, XRD results suggested that the… More >
