离子交换纤维(简称IEF),是在纤维的高分子链上带有离子交换基团的离子交换材料,它出现于五十年代,七十年代以后随合成纤维工业的兴盛而崛起。因其比表面要比常用的离子交换树脂(IER)大得多,且交换基团配置在纤维表面,故吸附、解脱速度快,交换效率高。此外,还具有良好的柔曲性,能加工成织物、无纺布、毡,呈任何几何形状,以适应不同应用场合的要求。 Ion exchange fiber (IEF) is an ion exchange material with ion exchange groups on the polymer chain of fibers. It appeared in the 1950s and 1970s with the rise of the synthetic fiber industry. Because of its specific surface than the commonly used ion exchange resin (IER) is much larger, and the exchange group is arranged in the fiber surface, so adsorption, release speed, exchange efficiency. In addition, it also has good flexibility, can be processed into fabrics, non-woven fabrics, felt, in any geometric shape, to meet the requirements of different applications.
