聚酯/锦纶6双组份纺粘水刺非织造布的光接枝亲水亲油改性

为了提高应用于擦拭布领域的聚酯/锦纶6（PET/PA6）双组份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，采用紫外光接枝的方法将AM和BA接枝到PET/PA6双组份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)等研究了接枝前后的PET/PA6双组份纺粘水刺非织造布的结构，并分析了其亲水性、亲油性和刚柔性等性能。结果表明，AM和BA成功接枝到PET/PA6双组份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。

Hydrophilic-lipophilic modification of PET/PA6 bicomponent spunbonded spunlaced nonwoven by ultraviolet grafting

Photografting of acrylamide (AM ) and butyl acrylate (BA) onto PET/PA6 bicomponent spunbonded spunlaced nonwovens applied in wiping field was conducted with benzophenone (BP) as photoinitiator, AM as hydrophilic monomers and BA as oleophilic monomers in order 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 hydrophilic, oleophilic and softness would rise with the increase of the grafting rate before they were reduced. It showed 39.25% increase in water absorption, 73.58% increase in oil absorption and the softness of the PET/PA6 nonwovens after grafting is good when the grafting rate was 18.32%.
