ABSTRACT
In this paper, the method of “hydrophobic modified coating” was used by introducing the low surface energy hydrophobic groups and silica nanoparticles on the surface of towel fabric. A hydrophobic lipophilic cotton fabric with biodegradability and super absorbent capacity was prepared by modifying the surface by silica nanoparticles. The surface structure was characterized by Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM). The performance indexes such as oil absorption ratio and oil retention rate were tested and evaluated. The results revealed that the hydrophobicity and oil absorption properties of the cotton fabrics were significantly improved after hydrophobic modification. The water contact angle is 140° and the oil contact angle is 0°, showing strong hydrophobicity of the modified fabric. In addition, the modified cotton fabric had an oil retention rate of 84.6%, which can be avoided as secondary pollution during the recycling of saturated pure cotton fabric. Moreover, the cotton fabric with residual oil can be used for power generation fuel, high fever, high enthalpy, and flammable ashless products.
摘要
本文采用“疏水改性涂料”的方法，在毛巾织物表面引入低表面能疏水基团和二氧化硅纳米颗粒，用改性剂制备了具有生物降解性和高吸收性的疏水性亲脂性棉织物。二氧化硅纳米粒子表面的表面化。采用傅立叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）对其表面结构进行了表征，并对其吸油率和吸油率等性能指标进行了测试和评价，结果表明：疏水性和吸油性均较好。棉织物经疏水改性后，各项指标均显著提高。水接触角为140°，油接触角为0°，改性织物具有较强的疏水性，改性棉织物的保油率为84.6%，可作为饱和纯棉织物再利用过程中的二次污染。此外，具有残余油的棉织物可用于发电燃料、高热、高焓和易燃、无灰产品。
