摘要
以活性黄分别和氧化镧、氧化镨、氧化钕、氧化钐、氧化铕、氧化钆、氧化镝、氧化镥、氧化钇等为原料,制备了活性黄镧、活性黄镨、活性黄钕、活性黄钐、活性黄铕、活性黄钆、活性黄镝、活性黄镥、活性黄钇等染料,并且用这些染料对真丝绸进行了染色,其上色率和固色率远大于活性黄染料。分别测定了活性黄及活性黄稀土染料的紫外可见光吸收光谱。在200.00- 800.00 nm范围内,测定了活性黄及活性黄稀土染料的最大吸收峰的波长。
Reactive yellow rare earth dyestuffs are prepared by using reactive yellow and lanthanum oxide, praseodymium oxide,neodymium oxide,samarium oxide,europium oxide,gadolinium oxide, dysprosium oxide, lutetium oxide,yttrium oxide respectively for dying silk cloth. Compared with that of reative yellow, the degree of dying and fixation of reactive yellow rare earth dyestuffs rises remarkably. The UV-VIS spectrum of reactive yellow rare earth dyestuffs and reactive yellow dyestuff are studied. In 200.00-800.00 nm.the λmax of reactive yellow,reactive yellow lanthanum,reactive yellow praseodymium,reactive yellow neodymium, reactive yellow samarium, reactive yellow europium, rective yellow gadolinium, reactive yellow dysprosium, reactive yellow lutetium and reactive yellow yttrium are 383.00 nm,382.50 nm,383.00 nm,382,50 nm,382,50 nm,383.00 nm,382,50 nm,383.00 nm respectively. Reactive yellow praseodymium,reactive yellow neodymium,reactive yellow gadolinium, reactive yellow dysprosium, reactive yellow yttrium and reactive yellow have the same color.
