测试其拒水性和紫外防护性能，皂洗次数对整理前
后的亚麻织物性能的影响数据如表 3 所示。从表 3
可以看出，随着皂洗周期达到 20 次，GO 整理亚麻
织物的水接触角和 UPF 均有明显下降，说明 GO 与
织物的结合力不强，部分石墨烯片层脱落导致性能
下降，这与观察到的 GO 整理亚麻织物的 SEM 图结
果一致。而 FSiAc 乳液整理亚麻织物的水接触角和
UPF 下降不明显，说明乳液在织物表面结合牢固。
因此，GO/FSiAc 复合乳液中由于 FSiAc 乳液的存在
使亚麻织物的水接触角和 UPF 下降更为缓慢，皂洗
20 次后，GO/FSiAc 复合乳液整理亚麻织物的水接
触角仍达到 142.00°，UPF 仍达到 162.22，此时测得
的 T UVA 仍为 0.94%，证明 GO 片层与 FSiAc 乳液的
层间作用以及 FSiAc 乳液的桥梁作用显著提升了整
理亚麻织物的耐久性。

整理
3 结论
（1）采用 Hummers 法制备了 GO，利用半连续
种子乳液聚合法合成了 FSiAc 乳液，将两者复合制备
成 GO/FSiAc 复合乳液整理剂，并采用轧-烘-焙工艺将
其整理在亚麻织物上，得到了具有拒水防紫外性且弹
性耐久性良好的多功能性亚麻织物。
（2）XPS 和 SEM 结果表明，GO/FSiAc 整理剂已
成功整理到亚麻织物表面并在织物表面形成了一层均
匀的拒水防紫外薄膜，含氟基团和 GO 片在织物表面
富集。
（3）GO/FSiAc 复合乳液整理亚麻织物的各项性
能明显优于原始亚麻织物、FSiAc 乳液整理和 GO 整
理的亚麻织物。m(BA)∶m(MMA)=7∶3、GO 质量浓
度为 4 g/L 时，整理后亚麻织物对水接触角可达
148.48°，UPF 可达 179.77，断裂强力达到 691 N，断
裂伸长率达到 14.5%。经 20 次皂洗后，整理亚麻织物
表现出较好的耐久性，并且保持了良好的透气性。
（4）GO 和 FSiAc 乳液复配整理亚麻织物的多功
能性仍需继续研究，如何发挥 GO 的特性及改进 FSiAc
第 39 卷
乳液的制备工艺，以进一步提升亚麻织物的应用性能
和服用性能将是接下来的研究重点。
