改性非织造布溶胶复配比的实践

Practice of composite ratio of modifying nonwovens sol

以改性非织造布的溶胀性、重金属离子过滤性能、防紫外线性能与断裂强力为指标探讨丝胶/羊毛角蛋白/水性聚氨酯复配整理溶胶对非织造布改性的最优配比。测试结果表明,随着羊毛角蛋白比例的增加,改性非织造布的溶胀性降低,重金属离子过滤性能提高,防紫外线性能与断裂强力先增后减。当丝胶∶羊毛角蛋白∶水性聚氨酯=2∶2∶1时,在较低溶胀和较高强力下,改性非织造布的重金属离子过滤性能和防紫外线性能得到改善。

The optimum ratio of sericin/wool keratin/waterbased polyurethane composited finishing sol is discussed based on the swelling property,heavy metal ion filtration property,UV protection property and breaking strength indexes of modified nonwovens.The test results show that the swelling property of the modified nonwovens decreases with the increasing of the proportion of wool keratin,the heavy metal ion filtration property increases with the increasing of the proportion of wool keratin,and the UV protection property and breaking strength both increase first and then decrease with the increasing of the proportion of wool keratin.When the proportion of sericin/wool keratin/waterbased polyurethane is 2∶2∶1,the property of heavy metal ion filtration and UV protection of modified nonwovens are improved under the condition of lower swelling and higher strength.
