Study on Bacteriostatic Activity of Bamboo Pulp Fiber
In order to examine the bacteriostatic and bacteriostatic stability,bamboo pulp fibers were subjec-ted to tests and analyses of their morphological structure and chemical composition,and a bacteriostatic rate test was done by using Escherichia coli as the bacterial strain.In order to investigate the bacteriostatic components of the fiber,bamboo pulp fibers were conducted Soxhlet extraction by using a 75%ethanol solution,ultraviolet spectra of the extracts were tested together with chromogenic reactions.The results showed that the bacteriostatic rate of the bamboo pulp fiber was more than 93%,and the bacteriostatic rate of the fiber was reduced to 75.4%after the Soxhlet extraction with 75%ethanol solution.The results of UV spectra,infrared spectra and chromoge-nic reaction preliminarily deduced that the bacteriostatic components of the fiber contained phenolic compounds.To explore the bacteriostatic stability of bamboo pulp fibers,the influence rule of commonly used chemical rea-gents and dyes in dyeing and finishing process on the bacteriostatic rate of bamboo pulp fibers were analyzed.The results demonstrated that the bacteriostatic properties of the fibers were strongly affected by sodium hydroxide,hy-drogen peroxide had no significant effect on the bacteriostatic properties of the fibers,and conventional dyeing and finishing processing conditions did not seriously affect the bacteriostatic properties of bamboo pulp fibers.
