摘　　要：为提高聚酯/锦纶6(PET/PA6)双组分纺粘水刺非织造布的亲水亲油性能,以二苯甲酮(BP)为光引发剂、丙烯酰胺(AM)为亲水接枝单体、丙烯酸丁酯(BA)为亲油接枝单体,采用紫外光接枝法将AM和BA接枝PET/PA6双组分纺粘水刺非织造布表面以提高其亲水亲油性能。通过扫描电子显微镜(SEM)、红外光谱(FT-IR)、X射线光电子能谱(XPS)等研究了接枝前后PET/PA6双组分纺粘水刺非织造布的结构,并分析了其亲水性、亲油性和柔软度等性能。结果表明,AM和BA成功接枝到PET/PA6双组分纺粘水刺非织造布表面,且非织造布的亲水亲油性能和柔软度随着接枝率的增加先升高后降低。当接枝率为18.32%时,接枝后非织造布的吸水率提高了39.25%,吸油率提高了73.58%,非织造布的柔软度较好。Photografting of acrylamide（ AM） and butyl acrylate（ BA） onto PET / PA6 bicomponent spunbonded spunlaced nonwovens was conducted with benzophenone（ BP） as photoinitiator,AM as hydrophilic monomers and BA as oleophilic monomers to improve its hydrophilic-lipophilic properties.The PET / PA6 nonwovens before and after photografting were observed by scanning electron microscopy（ SEM） and characterized by Fourier transform infrared spectroscopy（ FT-IR）,X-ray photoelectron spectroscopy（ XPS）,water absorbency,oil absorbency and softness. The successful grafting of AM and BA on PET / PA6 bicomponent spunbonded spunlaced nonwovens was confirmed. Properties such as hydrophilicity,oleophilicity and softness rise with the increase of the grafting rate before they were reduced. It is shown that 39. 25% increase in water absorption,73. 58% increase in oil absorption and good softness of the PET / PA6 nonwovens after grafting when the grafting rate was 18. 32%.
