  Being a major textile exporting country, Pakistan exports textile products and earns a lot of money. On the other hand it spends huge amount of foreign exchange on importing textile auxiliaries like dye intermediates, dye fixing agents, fluorescent brighteners etc. formaldehyde precondensates with amino compounds and this forms an important class of polymers like Phenol-formaldehyde, Melamine-formaldehyde etc. used largely and effectively in textile industry as dye fixing agents. At present Dimethoylol Urea (DMU) is one of the main chemical is being imported from Germany and United States of America. Present project is an attempt to synthesize DMU locally on laboratory scale. Results revealed that formalin on treatment with urea at pH 7.5 synthesized low molecular weight precondensate (DMU) that was miscible with water. Optimum time period for the completion of reaction was found to be 2 hrs. Moreover it was determined that one mole of urea required 1.5 to 1.6 moles of formalin (formaldehyde) to react completely. The results revealed that DMU precodensate is the better for rayon as compared to cotton.
