摘要
采用甲醇、盐酸和水的混合溶液对槐花提取物进行水解,将芦丁转化为槲皮素,以增强染色棉的防紫外线效果。槲皮素的相对得率(%)由未处理的槐花提取物在359nm处的吸光度与370 ~ 371nm处的吸光度之比确定。在反应时间为60 min的条件下,1 M HCl的槲皮素得率为93.09%,0.5 M HCl的槲皮素得率为52.03%。将槐花水解液与水按50:50或75:25的比例进行染色。经槐花水解提取物染色后,棉织物的UPF值提高到13.80,对紫外线的阻隔率为92.76%,而未经槐花染色的棉织物对紫外线的阻隔率为84.78%。本方法可以生产出一种重量轻,颜色为黄色的夏季棉,可以为日常夏装提供适度的紫外线防护。
UV protection effect of cotton dyed with Flos Sophorae (Sophora Japonica L.) extracted with acid hydrolysis
Flos Sophorae extract was hydrolyzed using a mixed solution of methanol, HCl, and water to convert rutin to quercetin for the purpose of enhancing the UV protective effect of dyed cotton. Relative yield (%) of quercetin in the hydrolyzed extract was determined by the percent ratio of the absorbance of untreated Flos Sophorae extract at 359 nm to the absorbance of hydrolyzed extract at 370–371 nm. Quercetin yield was 93.09% when 1 M HCl was applied and 52.03% when 0.5 M HCl was applied, both with 60 min reaction time. The latter was applied in dyeing cotton with the dyebath containing hydrolyzed Flos Sophorae extract and water by 50:50 or 75:25 ratio. By dyeing with hydrolyzed Flos Sophorae extract the UPF value of cotton was enhanced to 13.80 indicating 92.76% blockage of the UV rays as opposed to 84.78% blockage by the same fabric without Flos Sophorae dyeing. The present method could produce a light-weight summer cotton with yellow color which could provide a moderate UV protection for daily summer attire.
