Synthesis of Bio-Based Non-Fluorinated Oil and Water Repellent Finishes for Cotton Fabric by Using Palmitic Acid, Succinic Acid, and Maleic Acid

ABSTRACT

Oil and water repellency is very important for certain textile end products. Traditional durable oil and water repellents contain fluorine or formaldehyde-based substances. These substances have a long-term negative impact on the human health and natural environmental, and therefore, they are being banned. To address this problem, scientists are continuously working on the development of new sustainable alternatives. In this regard, present paper reports the results of the successful development, optimization, and application of two ecofriendly oil and water repellents for cotton fabrics. In case of the first oil and water repellent development, present research polymerizes the bio-based palmitic acid with formaldehyde-free bio-succinic acid. While in the second oil and water repellent, this research polymerizes the bio-based palmitic acid with formaldehyde-free maleic acid. The developed polymers provided comparable or better performance properties with reference to the C6-based commercial fluorocarbon. In addition, the proposed polymers were successfully characterized using X-ray diffraction (XRD) analysis, FTIR analysis, H-NMR spectroscopy, energy dispersive X-Ray (EDX) analysis, and SEM analysis).

摘要

拒油和拒水性对于某些纺织最终产品非常重要. 传统的耐油防水剂含有氟或甲醛基物质. 这些物质对人类健康和自然环境具有长期的负面影响，因此被禁止使用. 为了解决这一问题，科学家们不断致力于开发新的可持续替代品. 在这方面，本文报告了两种生态友好型棉织物拒油拒水剂的成功开发、优化和应用结果. 在第一次开发防油防水剂的情况下，本研究将生物基棕榈酸与无甲醛生物丁二酸聚合. 而在第二种拒油拒水剂中，本研究将生物基棕榈酸与无甲醛马来酸聚合. 开发的聚合物提供了与基于C6的商用氟碳化合物相当或更好的性能. 此外，使用X射线衍射(XRD)分析、FTIR分析、H-NMR光谱、能量色散X射线(EDX)分析和SEM分析成功地对所提出的聚合物进行了表征.
