本研究是將Lyocell利用鹼處理及酵素處理後，探討Zeta電位的變化。當Lyocell以鹼處理後使纖維產生膨潤現象。而Lyocell經由酵素處理後，纖維表面的纖維素會受到纖維素酵素給分解，造成表面破壞。經由鹼處理及酵素處理後，可以發現，原纖受到濃度25%鹼處理及酵素處理後，Zeta電位分別是－17.73mv、-28.25mv、-31.49mv，可以明顯看出Zeta電位增高。進而可以推論，纖維受到膨潤後和表面有受到破壞，Zeta電位會明顯受到改變。

The research with Lyocell by caustic treatment and enzyme treatment, probe into the change of Zeta Potential. Lyocell make the swollen phenomenon by caustic treatment. Lyocell make with enzyme treatment. Cellulose of fiber surface make to decompose by enzyme treatment, produce to destroy on surface. through caustic treatment and enzyme treatment fiber make to 25% caustic treatment and enzyme treatment, Zeta Potential to differentiate -17.73mv、-28.25mv、-31.49mv, to find Zeta Potential with add. then all right inference, fiber make the swollen phenomenon, and produce to destroy on surface, Zeta Potential will be obviously received and changed.
