摘要
本文用可见光谱、红外光谱、热分析、纸色谱分析、X-射线衍射分析及电子显微镜等分析手段,研究了稀土与七种阳离子染料及稀土与两种腈纶纤维的相互作用。稀土对阳离子染料的可见光谱无显著影响,稀土使阳离子染料对腈纶纤维的直接性明显下降。稀土与腈纶纤维之间的化学作用非常微弱,但稀土对腈纶纤维的整列度、取向度、玻璃化转变温度等结构常数有较大影响。
By the usage of visible spectrum,infrared spectrum,thermal analysis,paper chromatography,X-ray diffraction analysing,and electric microphotograph,the authors analysed the relative reactionbetween seven kinds of cation dyestuffs and rare earth and two kinds acrylic fibres.There is noevident effect of rare earth on the visible spectrum of cation dyestuffs.However,rare earth makesthe direct action of dyestuff decrease evidently on acrylic fibre.Rare earth has a very weak chemi-cal reaction with acrylic fibre,but has a large effect on the structure constants of acrylic fibre,such as orientation,and glass temperature
