Bamboo pulp fibers, made of fast grown bamboo, were the recycled and environment-friendly natural raw materials in the textile industry which particularly today was paid more attention to its good performance due to energy and environment crisis. Hyper branched polymer was attracted more study because of the vast potential application in the future. In this study, the fabrics were modified with the amino-terminated hyper branched polymer (HBP-NH2) by dipping method and anti-UV and anti-bacterial properties of the treated bamboo pulp fabric were investigated. The results showed that the treated bamboo fabric had good antibacterial properties, the bacteria reduction of S.aureus and E.coli were as high as 89% or more, and also remained at around 88% after 20 times washing. The UPF values were increased from 8.16 to 18.18 which improved the anti-UV property of bamboo fabric.
