Good quality printing with reactive dyes using guar gum and biodegradable additives

摘要

In printing with reactive dyes sodium alginates or synthetic thickeners are typically used as thickening agents to prevent unacceptable fabric handle. A new reactive printing process for reactive dyes on cellulosic textiles has been developed using natural thickening agents an environmental-friendly additives. Printing trials with guar gums have shown that the use of different additives can prevent fabric stiffness. These additives. Printing trials with guar gums have shown that the use of different additives can prevent fabric stiffness. These additives have no significant influence on rheology and colour strength but contributed to soft fabric handle even when guar gums were used as thickening agent. The use of additives and guar gum provide good quality prints with reduced wastewater pollution.
