Bamboo fibers as a quality original textile materials has caused large numbers of consumers, prod

3、ucers and researchers concerned. This study mainly uses chemical treatment methods for chemical treatment of bamboo, including hydrogen peroxide and urea reagent pretreatment on bamboo processing, And then with a certain concentration of NaOH, Na2SO3, Na2SiO3, anthraquinones complex mixture of addit

4、ives to scouring the bamboo processing, and the proportion of different concentrations of additives on the scouring effect of the final washed in isolated natural bamboo fiber, Comparative Analysis of the best handling of the parameters of reagents, the use of best technology experiments. Then, in the pretreatment of H2O2 concentration 3 g / L, urea 8 g / L; alkali processing solution NaOH is 10 g / L, Na2SO3 is 2%, Na2SiO3 is 2% and anthraquinones of one percent additives, tempe
