Abstract

This study explores the surface modification of polyethene terephthalate (PET) fabric via glycolysis, employing choline hydroxide as an eco-friendly catalyst. A range of chemicals was evaluated for catalysing the glycolysis reaction. Among them, choline hydroxide demonstrated notable enhancements in surface hydrophilicity, moisture regain, wicking properties, and water contact angle, surpassing other catalysts. Scanning Electron Microscopy (SEM) revealed a marked increase in surface roughness and irregularities following glycolysis in the presence of this ionic liquid. The surface modification technique employed in this investigation resulted in a decrease of less than 20% in the breaking force of the fabric. Fourier Transform Infrared (FT-IR) spectroscopy and the methylene blue staining method confirmed the emergence of free hydroxyl groups on the modified fabric's surface. These findings suggest that glycolysis catalysed by choline hydroxide is a promising approach for enhancing the surface characteristics of polyester fabrics, which may lead to improved functional properties in textile applications.

利用氢氧化胆碱催化糖酵解对聚酯织物进行表面改性

本研究采用氢氧化胆碱作为环保催化剂，探索通过乙二醇反应对聚对苯二甲酸乙二酯（PET）织物进行表面改性。研究评估了一系列用于催化乙二醇反应的化学品。其中，氢氧化胆碱在表面亲水性、回潮性、吸湿性和水接触角方面都有显著提高，超过了其他催化剂。扫描电子显微镜（SEM）显示，在这种离子液体的存在下，乙二醇的表面粗糙度和不规则性明显增加。这项研究采用的表面改性技术使织物的断裂力降低了不到 20%。傅立叶变换红外光谱（FT-IR）和亚甲基蓝染色法证实了改性织物表面游离羟基的出现。这些研究结果表明，氢氧化胆碱催化的糖酵解是增强聚酯织物表面特性的一种很有前景的方法，可改善织物应用的功能特性。
