ABSTRACT
Fluorinated compounds provide excellent oil and water repellency to cotton fabrics. But, they have various toxic effects on human health and the environment. To address this challenge, scientists are continuously struggling to develop the eco-friendly oil and water repellents. To support these efforts, this research focused on the synthesis of some bio-based and non-fluorinated oil and water repellent recipes for the cotton fabric through the polymerization of palmitic acid with an eco-friendly cross-linker “citric acid” considering the effects of catalyst, enhancer, time, temperature, and polymerization environment. After the numerous trials, an optimized water repellent finish has been developed. The performance of the cotton fabric treated with the newly developed water repellent was measured in terms of the oil and water repellency, crease recovery angle, contact angle, stain release, air permeability, shrinkage, washing durability, tensile strength, tear strength, and antimicrobial performance. Finally, the characterization of the optimized recipes and the treated fabric was performed through the various techniques such as H-NMR spectroscopy, scanning electron microscope (SEM), Fourier-transform infrared spectroscopy (FTIR), Energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). The results exhibited the successful synthesis and application of the newly developed recipes onto the cotton fabric.
摘要
氟化化合物对棉织物具有极好的拒油拒水性能. 但是，它们对人类健康和环境有各种各样的毒性作用. 为了应对这一挑战，科学家们一直在努力开发环保型拒油拒水剂. 为了支持这些努力，本研究集中于通过棕榈酸与环保交联剂柠檬酸的聚合，综合考虑催化剂、促进剂、时间、温度和聚合环境的影响，合成一些生物基和无氟的棉织物拒油拒水配方. 经过多次试验，研制出一种优化的拒水整理剂. 测试了经新型拒水剂处理的棉织物的拒油拒水性能、折皱回复角、接触角、脱渍性能、透气性、缩水率、耐洗性、拉伸强度、撕裂强度和抗菌性能. 最后，通过核磁共振波谱、扫描电镜、傅立叶变换红外光谱、X射线能谱和X射线衍射等技术对优化配方和处理后的织物进行了表征. 结果表明，新配方的合成及在棉织物上的应用是成功的.
