Foaming indigo: An efficient technology for yarn dyeing
The global production of denim fabric is more than 9 billion meters, and indigo dye, an essential dye in the denim field, uses about 30–50 tons of water per million meters in the washing process after dyeing in order to remove the floating color. At present, the most common cotton yarn dyeing process is the traditional process of dyeing, using the multi-vat immersion dyeing method of the assembly line. In order to successfully reduce the water and energy consumption with the foaming process, it is necessary to combine the foam system by indigo reduction method. This study through the foam system selection and process optimization,The results showed the concentration of sodium dodecyl sulfate is 3 g/L, the concentration of citric acid is 1.2 g/L, the temperature is 50 °C, the speed is 1200r/min, and the stirring time is 5min. A simulated factory yarn-dyeing line was built, Through orthogonal test, sodium Hydrosulfite concentration and sodium hydroxide concentration required for 5 g/L indigo reduction were 7 g/L and 3 g/L, respectively. When the temperature was 80 °C, the reduction effect of indigo was the best. Taking the K/S value of cotton dyed with 5 g/L traditional process as the control, the required concentration of indigo dye foaming process was determined to be 14 g/L at 50 °C, and the foam indigo foaming technology was realized. By comparing the twist, single yarn strength, and hairiness tests of the dyed cotton yarn with the two technology, the results showed that the properties of the dyed cotton yarn with the foam indigo technology dye are better than the traditional technology. Compared with traditional technology, foam technology saves about 53.5% water and has an efficiency ratio of 1:10.
期刊介绍:
Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied.
Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media.
The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
