Study on the enzymatic refining of natural bamboo fibers

The effects of enzymatic treatment on the refining of natural bamboo fibers were studied.The experimental results showed that the fiber linear density gradually decreased to a constant and the residual gum firstly decreased and then increased with the increasing of cellulase concentration,treatment time and temperature.And the optimum conditions could be expressed by cellulase concentration of 1.5%,treatment time of 180 min and temperature of 55 ℃.The fibers after treated had the linear density of 6.58 tex,decreased by 35.5% than those untreated,and the content of residual gum of 18.43%,decreased by 15.14%.
