摘要: A new dyeing process of sol–gel silica doped with direct dyes is investigated for improving color strength (K/S value) and fastness. Cotton fabrics are dyed in this dye solution. The results indicate that the K/S value C.I. Direct Blue 86 Red 23 enhanced by 12.8% 16.8%, respectively. For 86, washing staining fastness improved half a grade, rubbing change one Compared to fabric fixed fixing reagent MMF-1, about 23.7% wet grade. formation uniform continuous layers on fiber surface solution revealed video microscope, calculated weight gain 4.6%.
