Chitosan (CS) and graphene (Gr) were used to modify bamboo fiber fabrics to develop new bamboo fiber fabrics (CGBFs) with antimicrobial properties. The CGBFs were prepared by chemical crosslinking with CS as binder assistant and Gr as functional finishing agent. The method of firmly attaching the CS/Gr to bamboo fiber fabrics was explored. On the basis of the constant amount of CS, the best impregnation modification scheme was determined by changing the amount of Gr and evaluating the properties of the CS/Gr modified bamboo fiber fabrics. The results showed that the antibacterial rate of CGBFs with 0.3 wt% Gr was more than 99%, and compared with the control sample, the maximum tensile strength of CGBF increased by 1% in the longitudinal direction and 7.8% in the weft direction. The elongation at break increased by 2.2% in longitude and 57.3% in latitude. After 20 times of washing with WOB (without optical brightener) detergent solution, the antimicrobial rate can still be more than 70%. Therefore, these newly CS/Gr modified bamboo fiber fabrics hold great promise for antibacterial application in home decoration and clothing textiles.
壳聚糖（CS）和石墨烯（Gr）被用于改性竹纤维织物，以开发具有抗菌性能的新型竹纤维织物（CGBFs）。通过以CS作为粘合剂助剂、Gr作为功能整理剂进行化学交联来制备CGBFs。探索了将CS/Gr牢固附着在竹纤维织物上的方法。在CS用量恒定的基础上，通过改变Gr的用量并评估CS/Gr改性竹纤维织物的性能，确定了最佳浸渍改性方案。结果表明，含0.3 wt% Gr的CGBFs的抗菌率超过99%，与对照样品相比，CGBF的最大拉伸强度在纵向提高了1%，在纬向提高了7.8%。断裂伸长率在纵向提高了2.2%，在纬向提高了57.3%。用无荧光增白剂（WOB）洗涤剂溶液洗涤20次后，抗菌率仍可超过70%。因此，这些新型CS/Gr改性竹纤维织物在家庭装饰和服装纺织品的抗菌应用方面具有巨大潜力。
