【文章摘要】： Textile printing is the most versatile and important method used to introduce colour and design to the textile substrate where in thickener plays an important role. The main function of thickener is to adhere or hold the dye particles in the desired place on the fabric until the transfer of dye into the fabric and its fixation is complete. Tamarind gum is mainly used as sizing agent for jute and cotton warps due to its excellent binding and film forming properties. It is used as substitute of starch due to its lower cost and better weaving efficiency. The unique property of tamarind gum i.e. high viscosity at low concentration and low molecular weight compared to other polysaccharide may be useful to make it suitable as thickener in textile printing. Main drawback of Tamarind gum is poor keeping property and it interferes with the reactive dye in reactive printing. This paper deals with improving the thickening properties of tamarind gum chemically to extend its application in reactive printing on cellulosic fabrics.
