碱减量-氟硅烷处理涤纶织物的拒水拒油性
|
摘要
对涤纶织物进行碱减量处理,然后用氟硅烷(1H,1H,2H,2H-全氟辛基三乙氧基硅烷)对其进行低表面能整理,探究碱减量处理对涤纶织物拒水拒油和防污性能的影响。分别采用接触角测试仪、冷场发射扫描电镜以及傅里叶红外光谱表征了联合处理后涤纶织物的表面性能。结果表明,当NaOH质量分数为5%,碱减量处理时间10 min,温度90℃时,碱减量-氟硅烷联合处理涤纶织物可获得超疏水性能,接触角为152.5°,滚动角为9.8°,拒油等级为5级,耐污等级5级。
Alkali deweighting finish of polyester fabric is carried out,and then is modified by fluoroalkyl silane finishing agent(1 H,1 H,2 H,2 H-perfluorooctyl triethoxysilane) for its low surface energy.The effect of alkali deweighting finish on water-and oil-repellency and stain resistance of polyester fabrics is investigated.The surface properties of fabrics are characterized with contact angle tester,scanning electron microscopy and Fourier transform infrared spectroscopy.The results show that the polyester fabric features super hydrophobic properties with 152.5° of the contact angle,9.8° of water rolling angle,Grade 5 of oil repellency and Grade 5 of stain resistance under the treatment conditions of 5% NaOH,alkali treatment at 90℃ for 10 min.
