摘要
采用传统方法对涤纶进行碱减量处理,再用聚丙烯酸对涤纶进行预处理以增加涤纶后续反应位点,然后利用正硅酸四乙酯在酸性条件下易水解碱性条件下易缩聚,以及涤纶耐酸碱的特性,对涤纶选择了先酸后碱一浴法采用直接加布工艺进行了表面粗糙整理。十八烷基胺具有长烷基链,整理织物后可降低织物表面能量。经碱减量/聚丙烯酸/正硅酸四乙酯/十八烷基胺处理后的涤纶织物具有疏水性能,静态水接触角达116°。SEM照片显示处理后织物与未处理织物相比较,处理织物表面粗糙程度明显增加。
To obtain hydrophobic polyester fabric alkali deweighting treatment was applied to polyester fabric to improve its physical properties.Polyacrylic acid was adopted next to increase reactive sits on polyester fibers for subsequent treatments.Because of the fact that tetraethylorthosilicate hydrolyzes preferably at low pH but it more likely condenses under alkaline conditions,the polyester fabric was firstly treated in acidic solution of tetraethylorthosilicate,and then in alkaline solution for surface roughness.Octadecylamine having a long alkyl chain was used for treatment of polyester fabric to reduce surface energy.After these treatments,the polyester fabric was found to be more hydrophobic and the static water contact angle on treated polyester fabric was increased to 116°.SEM images showed that the treated fabric had rougher surface than untreated one.
