The development of a mild and green method for separating natural fiber bundles from willow bark is an essential step in exploring and preserving their natural functions. The isolation of well-oriented fiber bundles from the bark of a fast-growing willow hybrid solely using sodium bicarbonate under mild conditions was successfully demonstrated. Additionally, Lyocell fibers were mixed with an equal amount of the willow bark fiber bundles and proved their ability to convert into spun yarns, which provided excellent protection for ultraviolet radiation (UPF > 140). Moreover, these yarns demonstrated strong antibacterial activity (A > 8) against the Gram-positive pathogen Staphylococcus aureus, resulting in complete eradication of viable bacteria after 24 -h incubation with the material. A laundering treatment had no effect on the UV protection or the antibacterial performance. Utilizing these inherent properties from natural fibers for technical textile applications is very promising.
