Dyeing of cotton with phthalocyanines

自本世纪初合成以来，酞菁类化合物一直是众多研究的对象。然而，由于它们在水和有机溶剂中的溶解性较差，限制了它们在纤维染色方面的研究和应用。在这项研究中，我们报道了在含有三氟乙酸和质子化的酞菁(MPC)的有机溶液中，用单体MPC对棉进行染色，得到蓝色和绿色的颜色。结果表明，本技术可应用于多种酞菁类化合物的染色，如：MPC，M=铜、氢、镍、镁、锌、钒等。作为有机溶剂，我们可以使用二氯甲烷、二甲苯和甲苯。染料的吸收光谱和X-射线衍射谱表明，该膜为A型。扫描电子显微镜(SEM)显示，棉花表面密布着MPC。随着电解时间的延长，微晶的数量增加。

Ever since their synthesis in earlv this century, phthalocyanines continue to be the subject of numerous studies. However, the studies and applications of their dyeing of fibers are limited because of their poor solubility in aqueous and organic solvents. In this study, we report the dyeing of cotton with phthalocyanines (MPc) using monomeric MPc from organic solution containing trifluoroacetic acid and protonated MPc, which gives blue and green colors. We conformed that the present technique can be applied to the dyeing of many phthalocyanines, e.g., phthalocyanines (MPc, M=Cu, H_2, , Ni, Mg, Zn, VO). As organic solvent, we coukd use diclorometahne, xylenne, and toluene. Absorption spectrum and X-ray diffraction pattern of the dyeing stuff showed that this film is a-type. Scanning electron micrographs (SEM) of the film shows that the cotton surface is densely covered with MPc. The amont of the crystallites increased with electrolysis time for 1 h.
