The colorants of kale powders were optimally extracted using an 1:1 mixture
solvent of ethanol and DMSO at 105℃ for 30 minutes obtaining a high yield of 359.7㎍
/mL chlorophylls. Low color fastness of the dyed fabrics with the extracts, particularly
against washing and solar radiation, can be overcome by the combined treatments of chitosan,
heat setting and tannic acid. Washing fastness to color change was improved from
rating 1-2 up to 5 due to the enhanced electrostatic interactions between the colorants
and the positive glucosamine unit of the chitosan in the cationized cotton. In addition,
the tannic acid treatment contributed to the additional increase in color fastness after the
sequential treatments of chitosan pretreatment, dyeing and heat setting. |
