Bio-based Phytic Acid/chitosan and Polycarboxylic Acid for Eco-friendly Flame Retardant and Anti-crease of Cotton Fabric

ABSTRACT

Cotton is one of the most common natural textile fiber, while the high flammability and easy to crease restrict its applications. Improving the flame retardancy and anti-crease property of cotton fabric is very important for its industrial applications. In this study, phytic acid and chitosan were used to construct bio-based IFR system which was used along with eco-friendly 1,2,3,4-butanetetracarboxylic acid (BTCA) to enhance the flame retardant and crease-resistant properties of cotton fabric simultaneously. The results of LOI and vertical burning indicated that the multifunctional modified cotton fabric would greatly improve the flame retardant properties. The modified cotton achieved the LOI values of over 31% indicating excellent flame retardancy. And the multifunctional modified cotton fabric obtained the CRA over 260° revealing excellent crease-resistant performance. This research provides basis for the development of multifunctional modification of natural cellulosic fibers to improve their flame retardant and crease-resistant properties using bio-based products and eco-friendly polycarboxylic acid.

摘要:棉是最常见的天然纺织纤维之一, 其高易燃性和易起皱性限制了其应用。提高棉织物的阻燃性和抗皱性对其工业应用具有重要意义。本研究以植酸和壳聚糖为原料构建生物基IFR体系, 并与环保型1,2,3,4-丁烯四羧酸(BTCA)结合, 同时提高棉织物的阻燃性和抗皱性。结果表明, 多功能改性棉织物的阻燃性能得到了显著提高, 改性后棉的极限氧指数 (LOI) 值达到31%以上, 表明其具有良好的阻燃性能。改性后棉织物的折皱回复角 (CRA) 超过260°表现出优异的抗皱性能。本研究为利用生物基原料和环保型聚羧酸对天然纤维素纤维进行多功能改性以提高其阻燃性和抗皱性提供了研究基础。
