利用电子束辐照对醋酯纤维进行预处理,研究电子束辐照对醋酯纤维结构、性质及生物降解性能的影响。通过扫描电镜、红外光谱、黏度测试等方法证明:电子束辐照使醋酯纤维表面产生刻蚀,纤维大分子链断裂,聚合度降低,提高了酯酶和纤维素酶对醋酯纤维的降解能力,且辐照剂量越大,处理后醋酯纤维生物降解性能越好。
The pretreatment of acetate fibers by electron beam irradiation was used to study the effects of electron beam irradiation on the structure, properties and biodegradability of acetate fibers. Scanning electron microscopy, infrared spectroscopy, viscosity test and other methods proved that electron beam irradiation caused the surface of the acetate fiber to be etched, the fiber macromolecule chain was broken, the degree of polymerization was decreased, and the degradation of acetate fiber by esterase and cellulase was enhanced Ability, and the larger the radiation dose, the better the biodegradability of the acetate fibers after treatment.
