Thickeners for textile printing were prepared from tamarind gum as per green
technology; this tamarind gum is composed of glucose, xylose and galactose at a ratio of 3: 2: 1 as islolated from tamarind seeds. In order to render the tamarind seeds soluble in water, they were submitted to chemical modification by carbamation followed by miniaturization through sonication.
The as prepared biopolymer was used as a thickener for textile printing of a natural dye colorant was extracted from the tamarind seed cover (coat) after being manually which separated from the seed.
To this end, we have the biopolymer ready for use as a thickener and the extracted colorant ready for use as natural dye. Addition of the two components to the printing mix would give rise to benign printing paste which could be successfully used in printing on various textile materials notably cotton, natural silk and wool after being mordanted. Nitrogen content, rheological properties, color strength and overall color fastness properties were evaluated.
