摘　　要：目的 对从废弃皮革提取的二次胶原纤维进行一系列性能评价,着重研究它在吸音、阻燃方面的性能,探究二次胶原纤维及其复合纱线、布料在包装领域应用的可能性。方法 采用SEM、氨基酸分析仪、傅里叶变换红外光谱分析、驻波管及氧指数法对二次胶原纤维进行测试,采用万能拉力机对复合纱线、布料进行力学测试。结果 二次胶原纤维具有多孔隙、多层结构的特点,其最佳吸声系数可达0.98,极限氧指数为34.7%,二次胶原纤维复合纱线、布料具有良好的力学性能。结论 实验结果表明,二次胶原纤维具有良好的吸音、阻燃性能,其复合纱线、布料具有良好的力学性能,在包装领域具有良好的应用前景。The work aims to evaluate a series of properties of secondary collagen fiber extracted from waste leather,especially the sound-absorbing and flame-retardant properties and explore the possibility of application of secondary collagen fiber and its composite yarn and cloth in packaging field. The secondary collagen fiber was tested by SEM, amino acid analyzer, Fourier transform infrared spectroscopy, standing wave tube method and oxygen index method. The mechanical properties of composite yarn and cloth were tested by universal tension machine. The secondary collagen fiber had porous and multi-layer structure. The best sound absorption coefficient was 0.98 and the limiting oxygen index was 34.7%. The secondary collagen fiber composite yarn and cloth had good mechanical properties. Therefore, secondary collagen fiber has good sound-absorbing and flame-retardant properties, and its composite yarn and cloth have good mechanical properties, which has a good prospect in packaging application.
