摘　　要：The effects of coagulation conditions on tensile properties of the regenerated cellulose fibers prepared by wet-spinning from NaOH/thiourea/urea(8∶6.5∶8 by weight)aqueous solvent were investigated by tensile tester,X-ray diffraction(XRD),and scanning electron microscope(SEM).The results show that the tensile properties of the as-spun fibers change with the coagualtion concentration,temperature,and time.When the spinning solution is coagulated in 10% H2SO4/12.5% Na2SO4 aqueous solution,the as-spun fibers have a typical structure of cellulose II,a circular cross-section,and homogeneous morphological structure.The effects of coagulation conditions on tensile properties of the regenerated cellulose fibers prepared by wet-spinning from NaOH/thiourea/urea （8 ： 6.5 ： 8 by weight） aqueous solvent were investigated by tensile tester, X- ray diffraction （XRD）, and scanning electron microscope （SEM）. The results show that the tensile properties of the as-spun fibers change with the coagualtion concentration, temperature, and time. When the spinning solution is coagulated in 10% H2SO4/12. 5% Na2SO4 aqueous solution, the as-spun fibers have a typical structure of cellulose II, a circular cross-section, and homogeneous morphological structure.
