44 KKU Science Journal Volume 40 Number Review ABSTRACT Indigo blue can be extracted from many tropical plants It is insoluble pigment in water Before dyeing, the must be base-oxidized to leuco form ) which is colorless and dissolves in water The process was reduced by reducing agents under alkaline condition For industry process, sodium dithionite dissolve in sodium hydroxide were used as using potassium nicklecyanide as catalyst under nitrogen condition, which was satisfying outcome Zinc lime vat is one of preparing Indigo blue, zinc powder, lime and methanol were reduced bath with lower temperature than 60 C However, repeating of dye process can be decomposed the yarn The process of Indigo blue fermentation was used ash lye and need microorganism for equilibrium, this process used among Japanese, Korean, Laotian and Thai wisdom Indigo white is the better for textile dyeing such as cotton Indigo gave the bluish to dark blue color on the cotton, whereas the affinity of for dyes is weaker for third of cotton Several time in dyeing process can be denature protein of silk Fabrics of silk are less resistance under alkaline condition comparing to cotton According to chemical structure of Indigo white, the numbers of hydrogen bond between Indigo white and cellulose of cotton are higher than Indigo white and protein of silk That result for silk obtains less blue in the natural dye So the improvement of vat substance to mix with pigment in order to reduce the pigment particles together in the formation of the lowest alkaline and adding up some essential compound to extend the hydrogen bond between Indigo white and silk : Keywords: Indigo dyed silk cloth, Natural, Indigo dyed cotton cloth 553 40
