摘　　要：采用三聚氰胺和甲醛与对苯二甲醛在碱性条件下合成改性三聚氰胺甲醛树脂,然后将聚合物改性三聚氰胺甲醛树脂与粘胶溶液共混纺丝制备网状结构的纤维。使用扫描电子显微镜(SEM)、傅氏转换红外线光谱分析仪(FTIR)等分析了改性三聚氰胺树脂对粘胶纤维的成形及力学性能方面的影响。结果表明:改性三聚氰胺与粘胶纤维共混所得纤维的电镜照片中没有相分离现象,证明二者相容性较好;且在力学性能方面改性纤维相比与未改性纤维其断裂强度提高了26.3%,说明改性三聚氰胺的加入改善了粘胶纤维的力学性能。To enhance the mechanical properties of viscose fiber, a new method was proposed by blending viscose with melamine formaldehyde resin for spinning. The compatibility and enhancement mechanism between modified melamine formaldehyde resin and viscose fiber were studied by scanning electron microscopy （SEM） , Fourier transform infrared spectroscopy （FTIR） , thermogravimetric analysis （DTG）, nitrogen content and tensile strength. Results of SEM, FTIR, DTG and other comprehensive analysis showed that modified melamine formaldehyde resin and viscose fiber had a better compatibility, which means the modified melamine resin was successfully melted and blended with the viscose fiber. There was no macromoleeules existed on the face of solid particles, and no phase separation phenomenon founded from the scanning electron microscopy photos. All the results indicated that the modified melamine formaldehyde resin had better compatibility with the viscose fiber. Besides, the breaking strength of the modified viscose fiber increased by 26% compared to the ordinary one.
