核桃青皮天然色素的染色性能
Dyeing properties of natural pigment from walnut green peel
摘要
Abstract
Walnut green peel,which was a by-product of walnut,was largely discarded,in order to im-prove the utilization rate of walnut green peel,walnut green peel pigment was extracted by ethanol extraction from walnut green peel,the pigment stability was determined,and the cotton fabric was dyed by four meth-ods:direct method,same bath method,pre-medium method and post-medium method,the color difference and color fastness of different dyes were compared,and the optimized dyeing method was selected.The re-sults showed that walnut green peel pigment had good stability,and the best dyeing performance was post-medium method.Therefore,the extraction of pigment from walnut green peel not only reduced the waste of resources,but also reduced the pollution of the environment,which was of great significance for improving the utilization rate of walnut green peel.关键词
