ABSTRACT:
This invention relates to a process for making textiles containing cellulose crease-resistant.
The process of the invention involves contacting the textile with an aqueous treatment bath to which alkali chlorides or bromides of sodium and potassium have been added and which contains 1,3-dimethylol-4,5-dihydroxyethylene urea, the hydroxyl and methylol groups of which can optionally be partially or completely etherified with low, monohydric aliphatic alcohols with 1 to 3 carbon atoms and potential acid catalysts. It is possible for the treatment bath to contain in addition other precondensates normally used in the treatment of textiles provided at least 40% by weight based on the weight of the sum of the N-methylol derivatives calculated as anhydrous substances is the optionally etherified 1,3-dimethylol-4,5-dihydroxyethylene urea. 1 to 12% by weight of the alkali metal chloride or a bromide of sodium and potassium based on the weight of the N-methylol derivatives calculated as anhydrous substances are employed in the treatment bath. After contacting the textile with the bath it is dried and heated to cure the resin and/or crosslink it with the fibre.
