【摘要】 将涤锦复合丝分离得到的单一组分超细涤纶和超细绵纶纤维放在同一分散染料染浴中，在不同的温度下染色，测得几种蒽醌染料和偶氮染料染色物的明度Ｌ·及ＰＥＴ／ＰＡ６两相间染料的分配系数Ｋ。通过染料与纤维的无机性／有机性值计算，结合实验结果的分析，表明蒽醌型分散染料适合于 ＰＡ６纤维的常压染色，但离温离压染色对 ＰＥＴ／ＰＡ６复合纤维不易匀染。偶氮型分散染料在ＰＥＴ／ＰＡ６两相间的分配系数Ｋ随温度变化较小，因而较适合于ＰＥＴ／ＰＡ６复合纤维的染色，能获得较均匀的染色效果。更多还原

【Abstract】 PET and PA6 microfibers, separated from PET/PA6 bicomponent fiber, were dyed at certain temperature ranging from 65 to 130 ℃ in one bath containing different single disperse dye. The lightness L * of the fabrics dyed with several anthraquinone dyes and azo dyes and the partition coefficient K of the dyes absorbed in two phases of PET and PA6 were tested. By calculating the inorganic-organic value of the dyes and fibers, and analyzing the experimental results, it is showed that anthraquinone disperse dyes are suitable for PA6 dyeing at atmosphere, while the partition coefficient of the azo dyes is about 1 and changes slightly with the temperature. So at high temperature, it proofs better uniform than the anthraquinone dyes.更多还原
