摘要(Abstract)：

以废弃胶原纤维为原料，优化氧化钙法胶原蛋白提取工艺，并将提取溶液作为胶黏剂用于废弃胶原成网固结，通过湿法成网制备废弃胶原非织造布。用扫描电镜对其结构进行表征，并对所制备的非织造布进行透气、顶破性能测试。结果表明：废弃胶原纤维呈束状排列，线密度和长度分别为(0.18±0.11) dtex和(17.8±6.4) mm,离散度较大；胶原蛋白最佳提取工艺为：温度70℃,反应时间80 min,氧化钙用量8%～14%;所制备的非织造布中胶原纤维排列杂乱，且纤维之间存在大量交叉和缠结，结构稳定；所制备的非织造布柔软且其厚度可调，交联后非织造布的顶破性能大幅提升，当戊二醛用量为5%时，非织造布顶破强力达96.9 N,透气性影响不大，是理想的高端擦拭用材料。

关键词(KeyWords)： 废弃胶原纤维;胶黏剂;湿法成网;非织造布;顶破性能
