ABSTRACT: The dyeing of wool, silk,
cotton, ramie, nylon, acrylic and polyester fabric by using the extracts from
mulberry branches and trunks was tried and the dyeability was studied. While
the dyeability of the ethanol-extracts from
mulberry is low, that of the water-extracts is high for wool,
nylon and silk fabrics. They are dyed brownish and yellowish colours. The obtained
colours depend on the extracts concentration in the dye solution, dyeing time, dye
solution pH and dyeing temperature. Wool, nylon and silk fabrics are dyed
deeper with an increase in the dyeing temperature. The mulberry extracts show
fluorescence and reducing property. The results indicate that the mulberry
extracts contain flavonols such as morin, kaempferol or quercetin, which form complexes
with Al3+ and show fluorescence. The wool treated with the mulberry
extracts or AlCl3/mulberry extracts shows fluorescence with
ultraviolet light irradiation.
