[BMIM]Cl离子液体处理对苎麻性能的影响
Effect of [BMIM]Cl ionic liquid treatment on properties of ramie
摘要
Abstract
The processing and consuming properties of ramie are dissatisfactory because of its high crystallinity and orientation degree. [BMIM]Cl ionic liquid, an eco-friendly solvent, was employed as modification reagent to improve ramie's properties. The ramie was swelled in ionic liquid containing some water for a period, and the crystal structure, weight loss, wetting ability, dyeing ability and tensile strength both before and after swelling were studied using different analysis methods. The results showed that ionic liquid had a distinct swelling effect on ramie fiber. The crystallinity of ramie fiber decreased after ionic liquid treatment, and some parts of hemicelluloses and pectin in ramie were removed by ionic liquid treatment with a weight loss upto about 5.3%. These changes in crystal structure and ramie component leaded to the improvement of wetting and dyeing properties, but the tensile strength of treated fiber was weaken in a certain extend.关键词
