摘　　要：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。Waste collagen nonwovens were fabricated using wet-laid technology with waste collagen solution as adhesive,which was extracted from waste collagen fibers using calcium oxide.The structure of waste collagen fibers and as-prepared nonwovens were characterized by SEM,and the properties of the formed nonwovens were investigated by ball bursting tester and fabric permeability meter.The results show that the waste collagen fibers are arranged in bundles with fineness and length of(0.18±0.11)dtex and(17.8±6.4)mm,respectively.The best extraction process of collagen is as follows:temperature 70℃,reaction time 80 min,calcium oxide dosage 8%-14%.Collagen fibers in the as-constructed nonwovens keep disordered and form stable structure with tangles.The as-prepared nonwovens are soft,and its thickness can be controlled by adjusting the slurry concentration.The bursting performance of crosslinked nonwovens is greatly improved.When the dosage of glutaraldehyde is 5%,the bursting strength is 96.9 N.The air permeability changes slightly.These results suggest potential for wet-laid waste collagen fiber nonwovens as high-end wiping materials.
