Synthesis of Nontoxic and Bio Based Oil and Water Repellent Polymers for Cotton Fabrics Using Stearic Acid, Succinic Acid, and Itaconic Acid

ABSTRACT

Fluorocarbon-based oil and water repellents are considered best in textile finishing due to their excellent performance. Although, long chain fluorocarbons are effective oil and water repellents but they are toxic and being banned. Therefore, the present study develops two fluorine-free water-repelling polymers for cotton fabrics using ecofriendly recipes containing bio-based stearic acid and formaldehyde-free succinic acid and itaconic acid. One optimized recipe was achieved through polymerization between bio-based stearic acid and succinic acid, and other optimized recipe was achieved through polymerization between stearic acid and itaconic acid. These two recipes were applied to cotton fabric, and treated fabric exhibited a water repellency rating of 4 and an oil repellency rating of 1. The proposed polymers exhibited good oil and water repellency and washing durability up to 10 washing cycles. However, after 20 washing cycles, the proposed polymers exhibited water repellency for ironed fabric and zero oil repellency. The proposed polymers exhibited comparable or better testing results than commercial C6-based fluorocarbon. The characterization of the two best recipes was carried out through H-NMR Spectroscopy, scanning electron microscope (SEM), Fourier-transform infrared spectroscopy (FTIR), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD).

摘要

氟碳基拒油拒水剂因其优异的性能而被认为是纺织品整理的最佳选择. 然而, 有效且含有高氟碳链的拒油拒水剂有毒且被禁止使用. 因此, 本研究采用含有生物硬脂酸, 无甲醛琥珀酸和衣康酸的生态友好配方, 开发了两种用于棉织物的无氟防水聚合物. 通过生物基硬脂酸与琥珀酸的聚合得到一个优化配方, 通过硬脂酸与衣康酸的聚合得到另一个优化配方. 将这两种配方应用于棉织物上, 处理后的织物的拒水性等级为4, 拒油性等级为1. 该聚合物具有好的拒油拒水性和耐洗性, 最多可洗涤10次. 然而, 经过20次洗涤循环后, 所提出的聚合物对熨烫织物表现出拒水性, 且拒油性为零. 与商用C6基氟碳化合物相比, 建议的聚合物显示出类似或更好的测试结果. 通过H-NMR光谱, 扫描电子显微镜 (SEM), 傅里叶变换红外光谱 (FTIR), 能量色散X射线光谱 (EDX) 和X射线衍射 (XRD) 对两种最佳配方进行了表征.
