Abstract

A novel fluorine-containing water-repellent agent (OFAE-SA-BA) was designed and synthesized by emulsion copolymerization, which was used to replace the commercial long fluorocarbon chain water-repellent agent. To improve water repellency, the intermediate and monomer containing two short fluoroalkyl chains were successfully synthesized and characterized by H NMR, C NMR and FT-IR, respectively. After being treated by the water-repellent agent, the surface chemical composition, molecular weight, thermal stability, surface morphology, wetting behavior, and durability of the modified cotton fabrics were characterized using X-ray photoelectron spectrophotometry (XPS), gel permeation chromatography (GPC), thermal degradation (TG), scanning electron microscopy (SEM), and video-based contact angle goniometry, respectively. The cotton fabric demonstrated water contact angle of 154.1°, both the water and oil repellency rating were grade 4. The durability of water repellency of the treated fabrics only decreased slightly after 30 times, which represented very good washing durability. The finishing agent did not affect the whiteness of the fabric.

摘要

一种新型含氟拒水剂（OFAE-SA-BA）通过乳液共聚合成，用于取代商业长氟碳链拒水剂。为了提高拒水性能，成功合成并通过 H NMR、C NMR 和 FT-IR 分别对含有两个短氟烷基链的中间体和单体进行了表征。经拒水剂处理后，采用 X 射线光电子能谱仪（XPS）、凝胶渗透色谱仪（GPC）、热降解（TG）、扫描电子显微镜（SEM）和基于视频的接触角测角仪分别对改性棉织物的表面化学成分、分子量、热稳定性、表面形态、润湿行为和耐久性进行了表征。棉织物的水接触角达到 154.1°，拒水和拒油等级均为 4 级。处理后的织物经 30 次洗涤后，拒水耐久性仅略有下降，具有非常好的耐洗性。整理剂不会影响织物的白度。
