ABSTRACT

Fluorinated compounds are exceptional to exhibit good as well as durable oil and water repellency. However, due to their adverse effect on human and ecology, these compounds are under immense pressure. In this research, stearic acid which is a long-chain bio-based fatty acid is polymerized with a bio-based cross-linker citric acid in the presence of a catalyst. Stearic acid is a fluorine-free, environment-friendly, and nontoxic compound as compared to fluorinated compounds. Optimization of various parameters such as dosage of monomers, polymerization conditions, time, and temperature was carried out. The optimized recipe treated cotton fabric exhibited appreciable oil and water repellency and contact angle as well as the additional performance properties like crease recovery, soil resistance, antimicrobial performance, and shrinkage. Furthermore, the characterization of finished fabric was also carried out by SEM, EDX, XRD, FTIR, ¹ H-NMR spectroscopy analysis.

摘要

氟化化合物具有出色的耐油性和耐水性。然而，由于它们对人类和生态的不利影响，这些化合物承受着巨大的压力。在这项研究中，作为长链生物基脂肪酸的硬脂酸与生物基交联剂柠檬酸在催化剂存在下聚合。与含氟化合物相比，硬脂酸是一种无氟、环保、无毒的化合物。对单体用量、聚合条件、时间、温度等参数进行了优化。经优化配方处理的棉织物表现出明显的拒油拒水性和接触角，以及其他性能特性，如折痕恢复、抗污性、抗菌性能和收缩率。此外，¹  H-NMR光谱分析。
