【摘要】 为解决桑叶作为天然植物染料源在工厂实用化中的一些问题进行了本研究。桑叶染色液既可用鲜桑叶也可用桑叶粉提取,用桑叶粉有利于工厂贮存和加工;桑叶粉可由桑叶经日晒粉碎、烘干粉碎得到,日晒式节约、方便,即有利于农户也有利于厂商;桑叶提取染色液为碱性、在阴凉的室温下避光可以保存一段时间,还原剂的加入可使保存时间延长;用20g/L的Na OH作为提取剂时,采用大浴比1∶100,一次性沸煮提取的方法较节约。更多还原

【Abstract】 The problems of mulberry leaf as a natural plant dyestuff in the factory practicality were studied. Mulberry leaves dye liquid can be extracted from mulberry leaf powder or fresh mulberry leaves,but mulberry leaf powder more available for storage and processing in the factory. Mulberry leaf powder could be obtained from fresh mulberry leaves by solar drying or heat drying,and then to crush. The way of solar drying was economic and convenient,and it was beneficial to the farmers and manufacturers. Dyeing liquid extracted from mulberry leaf was alkaline; it was stable for days when keep in dark place,and even a long time in the presence of reductants. The optimum condition was 20 g / L Na OH solution with bath ratio 1∶ 100 as extraction agent and boiling once.更多还原
